What you should do if your MacBook charger stops working

Not being able to use your MacBook for any reason can be frustrating and even scary. So when it stops charging, you might jump to the conclusion that your MacBook’s battery or other hardware is to blame. 

It’s important to look at every possibility before assuming the worst. In this guide, we’ll look at the different reasons why your MacBook charger may stop working. Then, we’ll walk you through possible solutions for each problem.

Make sure the charger isn&#;t malfunctioning

MacBook Charging Cable

When first encountering charging issues, make sure the power adapter isn&#;t the underlying problem. Switch to a different outlet that you know works, and check the charger&#;s LED indicators &#; many Mac chargers have some form of these &#; to see if they respond. You don&#;t want to worry yourself over a faulty outlet.

If you get no response, consider borrowing an identical charger (if possible). You can also head to an Apple Store or an Apple Authorized Service Provider and ask if you can test your unit.

If your MacBook turns on and starts charging with a different cable, your charger is likely the culprit. If your MacBook still fails to respond, you probably have a problem with the battery or other hardware, and it&#;s time to take a different approach.

This is also the perfect time to check compatibility. The evolution of Apple&#;s MacBook lineup over the years introduced a handful of different power connectors and wattages. While you can acquire power adapters that output higher power than what your MacBook requires, using an adapter that doesn&#;t deliver enough power can lead to performance issues.

If you bought a charger or a used or refurbished Mac online and your charger doesn&#;t work upon first use, make sure you have a compatible charger type.

Apple has more information about the different power adapter connectors that work with old and new MacBooks and how you can get the correct adapter, if necessary. Here are the five major connection types:

MacBook Power Connectors

Clean it out

After confirming that the charger is your issue, check for dirt in all ports and connectors. A layer of dust or grime may be present, preventing the charger from making a proper electrical connection. Also, beware of invisible, sticky layers that may be the real problem.

To clean, get a cloth or cotton swab and remove any dirt you see. You can also use a quick spritz of isopropyl alcohol on the connector, but make sure to dry the charger thoroughly before using it again.

Check for physical damage

A common cause of charger failure is physical damage. There are two types:

Dirty Pins

Prong and blade damage: Examine all prongs, blades, and other metal tips used by your charger. If a prong or blade is loose or missing, your MacBook won&#;t receive enough power, if any at all. Physical damage can cause electrical fires, so stop using your charger and get a replacement immediately.

Apple Strain Relief

Strain relief: Strain relief refers to the head of the charger, which plugs into the MacBook, slowly disconnecting from the main cable. Caused by wear and tear, this issue appears more often on older connectors than power adapters with L-style or other MagSafe connectors.

If the LED indicator lights seem to switch on and off based on the angle of the charger, you could have a short. Examine the connector&#;s end for signs of cable damage, exposed wires, or wear on the insulating covering. If you see evident signs of damage, it could be dangerous; get a replacement soon.

Make sure your charger isn&#;t overheating

If the large, boxy part of your charger remains hidden under blankets, sits in the hot sun, or otherwise resides in a heated area, it may overheat. Adapters are very sensitive to heat, which is why Apple installs automatic shut-off functions for when they get too hot. That means your MacBook will never charge if you keep charging it in a hot environment. Make sure your adapter is always in the shade and well-ventilated.

Check for line noise

Belkin BE Outlet

Alternating currents move in cycles, but between the distance electricity must travel and the electromagnetic interference of nearby devices, these cycles can get exposed to serious distortion &#; that is, until the electricity essentially breaks down into a format your laptop battery simply can&#;t use. Check to see if you have a line noise problem by unplugging your charger and letting it rest for 60 seconds or so. Then, plug it back in and see if it works.

If the charger seems fine again, you probably had a problem with ground noise building up until your adapter shut down automatically to protect itself. Try using your computer away from other appliances, especially refrigerators and fluorescent lights, which are notorious for causing line noise troubles. Your adapter&#;s overvoltage protection feature is merely a safety precaution, and it is intended to increase the lifespan of your device.

Reset your battery and settings

Macbook Air () Review

If you&#;re still having trouble figuring out what&#;s going wrong, don&#;t lose hope. There&#;s one more thing you can do before you give up and take your MacBook to one of the pros. This possible quick-fix is associated with your computer&#;s specific settings rather than the adapter itself. We highly suggest trying out the following two solutions, as they may just be the answer to your problem (even if it&#;s hidden):

  • Reset your battery. This is very simple on older MacBook versions. All you need to do is remove the battery, allow it to sit idle for about a minute or more, and then re-insert it. Sadly, you cannot take the battery out using the same technique on the latest MacBooks. So, if this applies to you, you&#;ll need to skip to the next step. 
  • Reset your computer’s PRAM and SMC. These are in-house frameworks and settings that dictate how your MacBook controls power levels, volume amplification, and other essential settings. If these settings begin to malfunction, it can create severe concerns. Check out our guide on how to quickly reset PRAM and SMC on your Mac if you&#;re interested in learning more.

HOW TO FIX YOUR MACBOOK APPLE MAGSAFE CHARGER 1 \u0026 2, CABLE REPLACEMENT

There was once a time when buying a new laptop charger was difficult and expensive, but computers with USB-C charging have made replacements easier to get and more affordable than ever. The best choice for almost any modern tablet or laptop is Nekteck’s 60W USB-C GaN Charger. This adapter is just as powerful and reliable as a replacement from your laptop’s manufacturer, and it’s smaller than almost any other we’ve seen. It’s safety-tested and certified, and it comes with its own USB-C charging cable, making it a particularly great value at its very low price.

Whether you need to replace your original charger or just want to have an extra at home or the office, you should get the Nekteck 60W USB-C GaN Charger. It will charge almost any USB-C laptop at full speed, and it will fast-charge lower-powered laptops, tablets, and most modern smartphones, as well. The Nekteck is also smaller than just about any other or watt charger we’ve found and comes with a detachable cable, which is something that usually costs $10 to $20 on its own. This charger, like most of Nekteck’s products, is USB Implementers Forum (USB-IF) certified, which means an independent third party has tested it and ensured it meets performance and safety specifications. This certification is the biggest difference between the Nekteck and the ZMI zPower Turbo 65W, our runner-up pick. If the Nekteck’s price rises above $30, though, we recommend you consider the non-certified ZMI model.

Port 1: 60 W USB-C
Dimensions: by by inches
USB-C cable: feet, detachable

Nekteck’s 60W USB-C GaN Charger is the best charger we’ve tested, but if it’s out of stock or if the price jumps to over $30, we recommend grabbing ZMI’s zPower Turbo 65W USB-C PD Wall Charger instead. Its 65 watts is plenty of power for most laptops and any tablet, and like the Nekteck charger, the ZMI comes with a sturdy cable. The main reason it’s not our top pick is that the ZMI charger isn’t USB-IF certified. While that’s not a dealbreaker altogether, we think it’s worth a few more dollars to get the Nekteck charger.

Port 1: 65W USB-C
Dimensions: by by inches
USB-C cable: feet, detachable

We think you should choose one of our top picks (even if you have a tablet or a computer like the MacBook Air that requires less power) because they’re an incredible value, they’re quite small, and they provide more flexibility if you choose to upgrade to a more power-hungry machine in the future. But if size is your most important consideration and your devices only need 30 watts, Anker’s Nano II 30W is the charger to get. Its volume is less than half that of the Nekteck and ZMI picks, and its compact design won’t block any outlets when you plug it in.

Port 1: 30 W USB-C
Dimensions: by by inches
USB-C cable: not included

Almost all computers that charge via USB-C have a maximum charge speed of 60 watts—but the inch MacBook Pro can charge at up to 87 watts, and the inch model maxes out at 96 watts, making them the most noteworthy exceptions. For these laptops, the best option is Nekteck’s W PD GaN Wall Charger. This watt charger, which is notably smaller than Apple’s own charger, comes with a detachable USB-C charge cable and costs less than half the price of what a full replacement set would cost from Apple. Like our watt pick, it’s independently tested and certified for safety.

Port 1: W USB-C
Dimensions: by by inches
USB-C cable: feet, detachable

The Amazon Basics W Four-Port GaN Wall Charger matches the speed of our and inch MacBook Pro charger pick and has a second USB-C port plus two USB-A ports in a body that’s about the same size. This charger has a combined total output of watts, which means you can use the USB-C ports (one of which delivers up to W, and the other 18 W) to charge a single or inch laptop or a MacBook Air at full speed alongside an iPhone at just shy of its 20 W max. Having these two powerful ports in such a small package makes the Amazon Basics a great value for anyone who wants a single, travel-size charger for a laptop and a phone or other device. The USB-A ports charge at 12 watts, which is good enough for a reasonably quick charge with most modern smartphones when the USB-C ports are occupied.

Port 1: W USB-C
Port 2: 18 W USB-C
Port 3: 12 W USB-A
Port 4: 12 W USB-A
Dimensions: by by inches
USB-C cable: not included

Nekteck’s 5-Port W USB Wall Charger is a powerhouse if you’re dealing with multiple devices. It not only provides up to watt charging from its USB-C port—suitable even for power-hungry laptops like the or inch MacBook Pro—but it also has four USB-A ports for all your other devices and accessories like your phone, headphones, or a power bank. It comes with a USB-C charging cable, which makes it an even better value. But the weight and large size make it best suited for a permanent position on your desk.

Port 1: 87 W USB-C
Port 2: 12 W USB-A
Port 3: 12 W USB-A
Port 4: 12 W USB-A
Port 5: 12 W USB-A

USB-C cable: 3 feet, detachable

Everything we recommend

Why you should trust us

I’ve been covering power accessories since and reviewing them for Wirecutter since This includes several previous iterations of this guide and earlier versions of our Lightning cable, Micro-USB cable, and power bank guides.

Who this is for

This guide covers chargers for laptops that get power via a USB-C connection and specifically use USB Power Delivery (USB PD), a technology that lets USB-C transmit the high power required to charge a laptop. Most modern laptops, including almost all of those in Apple’s current lineup, charge using USB-C; cheap Windows laptops and gaming computers are the major exceptions.

With USB-C becoming common across phones, tablets, and laptops, you no longer have to rely on your device’s manufacturer to be the only source of a safe charger. Every computer comes with a charger, but at times you might need or want an extra: Some people like to have one charger that they leave on their desk and another to toss in their bag; others like to have a charger in every place they work. And, of course, sometimes chargers get lost or broken, so you need a replacement.

Larger laptops often need more powerful chargers to fill up their batteries at top speeds.

1iPad Pros from and originally shipped with an watt charger, which has since been replaced with an upgraded watt model. However, all – iPad Pros can actually charge at 30 watts.

Some tablets, most notably the iPad Pro lineup, also charge over USB-C, and our picks will allow you to charge them much faster than you can with the power brick that comes in the box. According to our testing, the watt charger that comes with the inch iPad Pro will charge the iPad’s battery to 18% after 30 minutes and 35% in an hour. A watt or faster charger almost doubles that, providing 33% charge in half an hour and 65% in one hour.

Thankfully, USB-C charging is starting to become cheaper and more accessible. You can also use one of these chargers with any USB-C tablet or smartphone, though most phones won’t benefit from higher USB PD rates—if you aren’t regularly charging a laptop, you can save a good amount of money by getting a lower-powered USB-C charger made for phones.

If you only want to charge a phone

  • The Best USB Phone Charger

    The Best USB Phone Charger

    No matter what kinds of USB-powered devices you own, we have picks to power them at their fastest charging speeds.

How we picked and tested

Five different USB-C chargers stacked one on top of the other.

The fact that so many companies can make similar, inexpensive USB-C laptop chargers—as opposed to the old days when you mostly just bought a charger from the company that made your computer—means it can be difficult to find the best charger among hundreds of options. We pored over the USB charging catalogs of Amazon, Anker, Apple, Aukey, Google, iClever, Nekteck, RAVPower, Satechi, Scosche, and ZMI, companies that have proven track records of making good charging products, to find the best competitors.

From there, we whittled the list down based on the following criteria:

  • USB-C ports with watt or higher output: Since many laptops charge at 45 watts or higher, that’s the minimum we initially considered for the chargers we tested. Anything lower than that will still charge these devices, but won’t do so at the maximum rate. We also tested watt and towatt chargers, which are capable of charging more powerful computers faster. For our most recent update, we tested five watt chargers to find a smaller alternative that can still charge the MacBook Air and some Chromebooks at their highest speeds.
  • USB-A ports with watt or QuickCharge output (if applicable): USB-A charging maxes out at 12 watts (5 volts, amps) for Apple devices and many Android phones, while some of the latter can charge faster with Qualcomm’s QuickCharge standard. For our picks with both USB-C and USB-A ports, we only considered chargers capable of this output. With the generally low prices of these chargers, you won’t find significant savings by choosing a slower one.
  • Power-to-dollar value: We considered the price of the charger relative to the total power it can put out across its ports. This comparison allowed us to rule out models that were more expensive but didn’t otherwise offer a higher power output or extra features.
  • USB-IF certification: Although not required for our picks, certification by the USB Implementers Forum (USB-IF) means an independent third party has tested the charger to make sure it adheres to specifications and is safe. While we test every charger we recommend, certification helps bolster the credentials of a charger, signaling that it’s well-made and that the company behind it has invested in its own reputation. Given two identical chargers, we’d choose the one with the certification.

We then tested a variety of chargers, including some with just USB-C ports and some with both USB-A and USB-C. To find the top options in each category, we put the finalists through a number of tests.

  • USB-C ports: We used Total Phase’s USB Power Delivery Analyzer and its Data Center Software to measure and record the power rates the chargers made available to connected devices, the actual power output observed when connected, how those compared with the advertised figure, and if there were any errors in how the charger and device talked to each other. USB-C uses digital communication between devices to verify charging speeds in a way that USB-A doesn’t; with this tool, we can observe and record what’s going on in the communication between the charger and the device you’ve plugged in.
  • USB-A ports: We tested how much power each USB-A port can provide. To do this, we plugged in a variable power load and an ammeter, which allowed us to finely control the power flow. We started with the power load set to 0 amps, and then turned it up until it matched the promised amperage, ensuring the voltage stayed within volts to volts. Then we repeated that test on each charger’s other ports, ensuring every port behaved as expected and that combined they matched the right output.
  • Combined power output: After assessing each port, we tested the combined output when all of them were in use by devices that take a lot of power. The best chargers will support full-speed charging to your phone on the first port even as you plug your headphones into the second port, a power bank into the third, and so on down the line.
  • USB-C cable testing: For the chargers that came with a USB-C cable, we used Total Phase’s Advanced Cable Tester to make sure the cable was safe and worked as labeled. The Cable Tester checks the wiring and signal integrity, DC resistance, and compliance with USB-C specifications. Nonstandard cables have been known to cause problems, including sometimes destroying the devices they’re meant to charge. We won’t recommend a charger that comes with a cable that fails our tests.

Our pick: Nekteck 60W USB-C GaN Charger

Our pick for the best replacement USB-C laptop or tablet charger, the Nekteck 60W USB-C GaN Charger.

Nekteck’s 60W USB-C GaN Charger is the best charger you can buy if you need a replacement for almost any modern laptop with a inch (or smaller) screen that charges via USB-C. It’s also a great option for the iPad Pro. It will charge your device fast, it’s small, and it’s safe, since it’s one of the few chargers (especially at its price) to be certified by the USB-IF. It’s also quite affordable—a fraction of you’d pay Apple for a replacement—even though it includes a foot, watt USB-C cable in the box.

Charging performance is the single most important factor in this product category, and this Nekteck brick performs exactly as expected: It offers enough power for almost any inch laptop, including the more power-hungry inch MacBook Pro. USB-C charging is standardized into different power levels, and the most common ones used with computers and tablets are 45 watts (15 volts, 3 amps) and 60 watts (20 volts, 3 amps). This charger supports the former but will automatically switch to watt, watt, and watt rates as needed to fast-charge phones and other devices. When plugged into a inch MacBook Pro, it properly charged at 60 watts with volts. It passed the Total Phase tests, as expected.

Close up of the Nekteck’s 60W USB-C port.

The Nekteck’s 60W USB-C port can power almost any inch or smaller laptop at full speed. Photo: Michael Hession

The 60W USB-C GaN Charger has often been on sale, sometimes for well under $ Even at its historical high price of $29 (as of this writing), it still costs only a third of what Apple charges for its comparable charger and cable. It’s such a strong value that we don’t think you should buy a lower-powered charger even if your device requires only 45 watts; those slower chargers aren’t any cheaper, and the watt option will potentially be more useful in the future.

In fact, it may even be worth it to buy the charger if you simply need a new cable, because the price is about the same. USB-C charging cables have come down in price alongside USB-C chargers themselves, but good ones still normally cost $10 to $ Nekteck includes cables with its chargers—and quality ones at that. This one only supports watt charging, though, so don’t expect to get full speed if you use it with more powerful chargers.

Nekteck is one of the few companies with USB-IF certification across its entire product line. That means an independent lab has verified that it meets an industry-standard set of criteria for safety and performance. Since we test all of our recommendations ourselves, we don’t rely exclusively on USB-IF certification to make a pick. But that stamp of approval on the company’s designs and adherence to USB-C standards gives the Nekteck charger another advantage over the competition.

Close up of a Nekteck charger connected with a cable to a laptop port.

The Nekteck charger is nearly the smallest USB laptop charger we tested at this power level, just a hair bigger than the ZMI zPower Turbo. Measuring by by inches, it has a volume that’s about half that of Apple’s 61W USB-C Power Adapter, and it’s small enough to throw in a computer bag or a jacket pocket. Folding prongs make it that much more compact.

Nekteck’s standard warranty period is 12 months, but a six-month extension is available if you sign up for the company’s newsletter. We’ve found the customer support to be helpful, both in terms of response speed and addressing our concerns.

Flaws but not dealbreakers

It’s hard to find fault with the 60W USB-C GaN Charger; it’s small, fast, and affordable. We don’t expect chargers to look beautiful, but if you do, or if you want something in an Apple-y white, you might be disappointed, as Nekteck’s charger only comes in black.

Runner-up: ZMI zPower Turbo 65W USB-C PD Wall Charger

A ZMI zPower Turbo 65W USB-C PD Wall Charger with usb-c cable connected.

ZMI’s zPower Turbo 65W USB-C PD Wall Charger is the best charger you can buy if the Nekteck 60W charger is out of stock, or is selling for more than $ It offers watt charging in a relatively compact package about the same size as the Nekteck. Like the Nekteck, it passed our Total Phase tests without any issues, which means that it will charge safely and correctly match the power level of whatever you plug it into. However, it doesn’t have USB-IF certification like the Nekteck charger does. ZMI includes a 5-foot, watt USB-C cable in the box, and that cable also passed our tests.

Close up of the ZMI’s single USB-C port.

The ZMI charger properly powered a inch MacBook Pro at 60 watts, and it showed the expected results in the Total Phase tests. Although it can provide up to 65 watts, the zPower Turbo’s extra power will only be accessed by more power-hungry devices, and even then, it won’t make a big difference in charging speeds. Although nice to have, the extra 5 watts doesn’t provide any practical value.

Measuring by by inches, the zPower Turbo is almost identical in size to the Nekteck 60W charger and once again about half the size of Apple’s 61W USB-C Power Adapter. The plain black box isn’t going to win any design awards, but with the contrasting glossy and matte surfaces it does look nicer than many chargers.

The 5-foot cable that comes with the watt charger is designed to support up to watts, which we verified with Total Phase testing. The charger and cable combo comes with an month warranty, as well.

For a MacBook Air and some Chromebooks: Anker Nano II 30W

The best laptop charger for MacBook Air and Chromebooks, the Anker Nano II 30W

We think most people should choose the Nekteck 60W USB-C GaN Charger or ZMI zPower Turbo 65W USB-C PD Wall Charger even if they use a device that only draws 30 watts, like a MacBook Air or Chromebook. That’s because despite delivering more power than necessary, they’re still quite small, their prices are very affordable, and they come with cables. They’ll also provide more flexibility down the road, if you upgrade to a more powerful computer. But if you want the smallest charger that will power your thin and light computer or tablet at its fastest rate, choose Anker’s Nano II 30W. It’s as small as the 5W charger Apple used to ship with iPhones, but our tests showed it properly can charge at up to 30 W.

At by x inches, the Nano II is smaller than any of our other picks and will take up little space in a bag. It won’t block other outlets when you plug it in, either. On the downside, the prongs don’t fold; if that bothers you, we have some other models worth considering in the Competition section. And unlike the Nekteck and the ZMI, the Anker doesn’t come with a cable, so be prepared to provide your own.

For a or inch MacBook Pro: Nekteck W PD GaN Wall Charger

Nekteck’s W PD GaN Wall Charger connected to a usb-c cable.

Nekteck’s W PD GaN Wall Charger provides enough power for a or inch MacBook Pro at less than half the price of one of Apple’s 96W USB-C Power Adapters. It’s smaller, too. You can find even smaller high-power-draw chargers, but they’re a lot more expensive than this particularly affordable model. We think it provides a great balance of price, size, and power.

Close up of the Nekteck W PD GaN Wall Charger's usb-c port.

The W charger can power anything that charges over USB, from phones to the inch MacBook Pro. Photo: Michael Hession

The square power brick is quite compact: Apple’s charger is inches square and just over an inch thick, while Nekteck’s is inches square and about inches thick. Both the Apple and Nekteck chargers have fold-out prongs, but the prongs on Nekteck’s charger can’t be removed and replaced with a longer cord as they can on an Apple charger.

Like the company’s 60 W charger, the W Nekteck charger is USB-IF certified, meaning an independent lab has verified that it meets a set of criteria for safety and performance. This Nekteck charger includes a 6-foot-long removable USB-C cable, adding to the value of the package. And if anything happens to the charger itself, Nekteck provides a month warranty.

Upgrade pick: Amazon Basics W Four-Port GaN Wall Charger

The best charger for charging USB-C computer and additional USB-powered devices, the Amazon Basics W Four-Port GaN wall charger.

The Amazon Basics W Four-Port GaN Wall Charger is the best solution for charging both your USB-C computer and additional USB-powered devices (such as a phone or Bluetooth speaker), and it can even handle two laptops at the same time. It’s a little larger than the Nekteck W PD GaN Wall Charger and offers the same amount of power, but it splits it up over more ports: two USB-C and two USB-A. You can get the full watt output from the top USB-C port, while the second supports watt speeds ideal for fast-charging phones like the iPhone or Google Pixel 5. The two watt USB-A ports, meanwhile, have a combined watt output, so you can charge one phone quickly or two at a slower rate.

The four ports on the Amazon Basics W Four-Port GaN Wall Charger.

Few travel-size chargers offer two USB-C ports, and even fewer offer the same overall power delivery as this Amazon charger. It can handle a wide array of devices, too: It allowed a proper watt draw when charging a inch MacBook Pro in our tests and was just as fast with the more powerful inch model as the included Apple charger.

That speed drops when you plug in a second device; combined, all four ports max out at watts. This means you can plug in a inch MacBook Pro (charging at 65 watts) and an iPhone (charging at 18 watts), and both will charge at full speed. But plugging in a inch MacBook Pro and an iPhone will result in slower than maximum charging speeds.

Amazon offers a month warranty on its products. This charger isn’t USB-IF certified, but having tested dozens of products from the company and evaluating customer reviews, we’re confident in this charger’s safety and durability.

Also great: Nekteck 5-Port W USB Wall Charger

A Nekteck 5-Port W USB Wall Charger with a usb-c cable connected.
A close up of the Nekteck charger's ports.

This five-port charger is the second most powerful USB wall charger we’ve ever tested, with a combined output of watts. We verified with the Total Phase tests that 87 watts are dedicated to USB-C charging. That’s the maximum charging speed of almost any laptop that charges via USB-C, although it’s just shy of the inch MacBook Pro’s watt rate. The remaining power is split between the four USB-A ports. Despite the charger listing each port as capable of watt charging when used individually, the highest we measured was about 10 watts—enough to charge your phone pretty fast but not at the absolute fastest rates USB-A offers.

The Nekteck 5-Port W USB Wall Charger is designed for your desk, not to be carried with you. It’s more than 6 inches long and 3 inches wide, and it weighs almost a full pound. But those dimensions (and the slightly slow USB-A charging) are a lot more acceptable at a desk, where the charger is likely to stay in one place and you might not need to gobble up power in a short period of time.

How to Fix a MacBook that Won’t Charge

Hardware:

Fraying MacBook power cord
Confession Time, 12/22/
Now that I&#;ve repaired this cord in the way I share below, I need to confess that this did not turn out to be a good long-term fix.  This method has worked find on the magsafe end but since the power brick gets hot, it melts the electrical tape and you end up with this situation:
The black sticky residue left by my electrical tape once the power brick got hot&#;not good

I have repaired my cord in another way, which is going to last a long time and I share how in another blog post here:  How To Repair a Fraying MacBook Power Cord &#; Take 2

Repair Attempt 1 (if you&#;re curious as to what didn&#;t work well):

I just noticed that of my MacBook Power Cords just started fraying.  I didn&#;t want to let it get bad before I protected it.  The best thing to do would be to put some heat shrink tubing on it but unfortunately the magsafe adapter on the end of the cord is pretty big and the heat shrink tubing that will fit over it won&#;t shrink down tight over the cord if it&#;s big enough to slip over.  You could just put a couple wraps of electrical tape on it but electrical tape just gets all sticky and doesn&#;t last very well.  So I chose a hybrid solution.

Step 1: Purchase some 1/2&#; (diameter) Heat-Shrink Tubing.  It is just big enough to slip over the magsafe adapter.  Get some heat shrink tubing here.

Step 2: Wrap electrical tape around the damaged area so that the diameter of the cord around the tape is at least 1/4&#;.  This way the heat shrink, shrinks down tightly around the electrical tape, supporting it and covering it up.

Step 3: Slip the heat shrink over the magsafe connector and over the electrical tape.

Step 4: Use a heat gun to shrink the shrink tubing over the electrical tape.  Be very careful because you could really burn yourself with a heat gun.

Finished product:

It&#;s not the most beautiful thing but it definitely extends the life of the power adapter.  I used this method to repair a different power cord on the MagSafe end and I was pleased with the result:

MagSafe is a series of proprietarymagnetically attached power connectors for Mac laptops introduced by Apple Inc. It was introduced on January 10, , in conjunction with the MacBook Pro, the first Intel-based Mac laptop, at the Macworld Expo. The connector is held in place magnetically so that if it is tugged (for example, by someone tripping over the cord) it will pull out of the socket without damaging the connector or the computer power socket, and without pulling the computer off of its surface.[1] A thinner and wider version, called MagSafe 2, was introduced in It was discontinued across Apple's product lines between and and replaced with USB-C. MagSafe returned to Mac laptops with the introduction of updated MacBook Pro models in with MagSafe 3.

History[edit]

The basic concept of MagSafe is derived from the magnetic power connectors that are part of many deep fryers and Japanese countertop cooking appliances since the early s in order to avoid spilling their dangerously hot contents.[2][3][4] MagSafe was introduced on January 10, in the first-generation MacBook Pro.[5] Apple was granted US Patent No. for MagSafe ("Magnetic connector for electronic device", issued in ) as MagSafe was deemed to be a sufficient improvement due to the connector being symmetrical and reversible, and the fact that magnets within a connector are arranged in opposing polarities for improved coupling strength.

Apple phased out MagSafe with the release of the inch MacBook and MacBook Pro that replaced it with USB-C for charging and data.[6][7] The last product with MagSafe, the MacBook Air, was discontinued on July 9, [8] The MagSafe connector returned in with the introduction of updated inch and inch MacBook Pro models.[9]

Apple also used the MagSafe trademark for a series of accessories based on the Qi standard for the iPhone 12 and 12 Pro.

Features[edit]

MagSafe (original)[edit]

MagSafe has connector pins that are designed so the rectangular connector can be inserted in either orientation. Originally the connector was T-shaped, with the cable directed straight out; later it became L-shaped, with the cable directed along the side of the computer, but still capable of being inserted in either orientation, unless simultaneous use of neighboring ports such as USB required directing the cable toward the rear. LEDs on both the top and bottom of the connector show green if the computer battery is fully charged and amber or red if the battery is charging. MagSafe can be found on the MacBook (–), MacBook Pro (–) and MacBook Air (–) notebook computers. The Apple LED Cinema Display and Thunderbolt Display include built-in MagSafe chargers.[10]

The MacBook and the inch MacBook Pro use a 60&#;W MagSafe charger, whereas the and inch MacBook Pro use an 85&#;W version. The MacBook Air used a lower-powered 45&#;W version. According to Apple, an adapter with a higher wattage than that originally provided may be used without problems.[11]

Apple formerly offered a "MagSafe Airline Adapter" for use on certain compatible airplanes. It had a DC input (instead of AC like the original MagSafe chargers) and would power the computer, but would not charge the battery.[12]

MagSafe 2[edit]

Close-up of the MagSafe 2 connector

MagSafe 2 was introduced on the MacBook Air and MacBook Pro with Retina Display at the Worldwide Developers Conference on July 11, It was made thinner to fit the thinner laptops, and also wider to preserve magnetic grip force. It also returns to the T-shaped design that points straight out, rather than the L-shape that runs along the side of the machine.[13] MagSafe 2 can be found on the MacBook Pro (–) and MacBook Air (–) notebook computers.

The resulting shape is incompatible with the older MagSafe connector; Apple released a MagSafe to MagSafe 2 adapter that was also bundled with the Thunderbolt Display, which used the original MagSafe connector.

MagSafe 3[edit]

On October 18, , Apple announced updated inch and inch MacBook Pro models with a new, slimmer, MagSafe 3 connector.[14] MagSafe 3 uses a removable cable with a USB-C end and supports up to W power delivery on the inch MacBook Pro with its bundled W GaN power supply that supports USB-C Power Delivery [15]

Pinout[edit]

The MagSafe connector pins allow for the adapter to be inserted in either orientation. The first and second pins on each side of the tiny central pin have continuity with their mirror pins.

  • The inner large pins are V+ ( / / / 20 V DC). Measuring with no load will give &#;V DC for MagSafe and about 3 V DC for MagSafe 2; the full voltage is provided after a ~40 kOhm load is applied for one second.[16]
  • The outer large pins are ground.
  • The tiny center pin is a data pin using the 1-Wire protocol. The computer uses this pin to change the LED's color and retrieve the serial number and wattage of the power supply.[16]
  • Only two wires, power and ground, go to the charger unit. There is no data communication via the adapter sense pin with the charger unit itself.[16]
  • The maximum voltage supplied is as follows:
    • V DC for the 45 W units supplied with MacBook Air
    • V DC for the 60 W units supplied with MacBook and 13" MacBook Pro
    • V DC for the 85 W units supplied with 15" and 17" MacBook Pro
    • 20 V DC for the 85 W units supplied with 15" MacBook Pro Retina

The rectangular metal shroud surrounding the pins acts as shielding for the electrical pins and a ferrous attractor for the magnet in the laptop.

Third-party products[edit]

Apple does not license the MagSafe connector to third-parties, though manufacturers devised a workaround: their MagSafe items use the actual connector from Apple's AC adapter, grafted onto their own products. Since this uses an actual Apple product, purchased legally, manufacturers believe that no licensing agreements are needed (a principle referred to as the first sale doctrine) and no patent was violated.[17] However, in Apple still sued one such manufacturer, Sanho Corporation for selling its very popular HyperMac battery extension products which Apple claimed violated their patents.[18] Sanho has since ceased to sell their connector cable for the HyperMac series of external batteries.[19]

Some fake MagSafe 2 chargers have appeared on sites such as Amazon. These chargers are often unsafe, have spelling mistakes on the charger itself, and/or have inconsistencies that the official product does not contain, e.g. the LEDs on the connector do not follow the correct color code, or the charger is referred to as a MagSafe 1 charger rather than the second generation charger.

Defects[edit]

Many users have reported (as of 30&#;October&#;[update]) problems with the quality of the construction of the MagSafe cords, giving the product low marks on the Apple Store's website.[20] Common complaints included plug separating from the cord, transformer shorting, and pin springs losing elasticity.[20]

Several methods have been devised to protect the MagSafe from failure, including wrapping the cable with tape or sliding protective plastic around the cable.[21]

In , Apple posted an official response acknowledging problems with MagSafe adapters, which include incomplete circuit connection and adapter's white insulation separating from the magnetic end of the MagSafe connector.[22] Following the release of a Knowledge Base article, a class-action lawsuit was filed on May 1, , in the US District Court for the Northern District of California's San Jose office, alleging that the MagSafe power adapter is prone to frayed wires and overheating, and as such represents a fire hazard.[23]

Apple released a firmware update in October that it claims resolves this issue.[24] However, the installer for the firmware update will not run on certain older MacBooks, which means that the firmware can not be updated. This, in turn, means that it is not possible to use the new MagSafe power adapter with these MacBooks. However, as of , Apple still sells the older MagSafe power adapter.[25]

In , Apple posted a support document about the strain-relief problems with the MPM-1 ("T")-style MagSafe power cables, and issued settlement offer for buyers of Apple 60&#;W or 85&#;W MagSafe MPM-1 adapter within the first three years of purchase.[26]
