Check the power

If your MacBook charger is not working, it won’t charge your MacBook’s battery. So you need to make sure the charger is working fine.

Check the power outlet

First, you need to make sure that the power outlet is ok. You can plug a lamp or an AC-powered clock into the power outlet. This simple step lets you know whether the power outlet is working or not.

Check the AC power cord

The MacBook charger comes with a removable AC power cord. Check the power cord for wear and tear. Insert the plug into the wall outlet firmly. Don’t forget to check the power cord on the charger side. Make sure you insert the power cord into the charger firmly as well.

Check the DC cable

Next, carefully inspect the charger’s output cable, starting at one end and working your way through until the other. Look out for any fraying or tears in the cable. If flaws are similar to those shown in the photo below, this is likely the problem. Replace the charger or try another available charger.

In addition, the USB-C charger uses a removable USB-C charging cable. Make sure the USB-C cable is fully inserted into the charger. Believe it or not, these simple checks often fix the MacBook battery not charging issue.

If your MacBook starts charging when you wiggle the USB-C cable, the cable is not connected properly. The removable USB-C cable is prone to get damage by bending the plugs at the two ends. Stop using the cable immediately and get a new replacement cable.

Check for charger overheating

The MacBook charger can become warm during normal use. If you place the charger in a poorly ventilated area, such as on a sofa, bedding or a pillow, the charger may turn itself off if it gets too warm. Unplug the charger immediately and let it cool down before using it again.

Check for AC line noise

The AC line noise from power tools, fluorescent lights, refrigerators, and other sources may interfere with the MacBook charger. The charger will shut down when it senses too much line noise from a socket.

Usually, the line noise won’t last long. Unplug the charger, wait for 1 or 2 minutes and plug the charger back in to see whether the charger works or not. Other solutions include using an uninterruptible power supply (UPS) to filter out the line noise or plugging the charger into a different circuit, eg., the other side of a house or office, upstairs or downstairs.

If your charger keeps turning off, you most likely have a faulty charger. You need a new charger.

Use the right charger

Apple uses a few types of chargers for different MacBook models. The MagSafe 1 and 2 chargers come in 45W, 60W and 85W. The USB-C chargers come in 30W, 35W, 61W, 67W,87W, 96W and 140W. The new MagSafe 3 chargers come in 67W, 96W and 140W.

You may quickly get confused with the chargers if you have a few MacBook Airs, MacBook Pros, iPads and iPhones in your household. The low-wattage adapters are used in low-power consumption MacBooks like MacBook Airs and 12″ MacBooks, while the high-wattage adapters are used in 15″ and 16″ MacBook Pros.

If you use a low-wattage adapter in a high-power consumption MacBook, the power adapter barely provides enough power to run your MacBook but not enough power to charge the battery.

For example, if you connect a MacBook Air charger (30W) to a 15″ MacBook Pro (87W), you could get a battery not charging notification, and the charger will get hot very soon. You may still use your MacBook without draining its battery, but the battery won’t charge. If you turn off the Mac or put it to sleep, the power adapter will start charging the Mac.

Please refer to Apple’s website to find out the original stock adaptor for your MacBook. Identify your Mac power adaptor.

No matter how many Apple chargers you have, the basic rule is that the high-wattage charger can replace the lower-wattage charger, not the other way around. You may notice the high-wattage charger outputs a higher voltage, but it doesn’t matter. The MacBook charging circuit on the logic board will automatically adjust the voltage for your MacBook. So a higher-wattage charger will not harm your MacBook.

Also, the MagSafe 1, MagSafe 2, and MagSafe 3 chargers are not exchangeable as the size of the connectors are slightly different. You can’t fit a MagSafe 3 plug into a MagSafe 2 charging port.

Check battery health management settings

The battery health management is on by default when you run macOS Catalina 10.15.5 on a MacBook with Thunderbolt 3 ports. Your battery may drain to 90% or lower before it begins to charge again. This design feature extends the life of your MacBook lithium-ion battery. You can turn off this battery health management feature in Energy Saver preferences. We don’t suggest you change the setting unless you have a particular need.

In macOS Big Sur or later, you may get a “Charging On Hold” message on the Battery Status menu, and the MacBook battery is not charging. This new feature is for learning your charging habit and optimising battery charging. When the feature is enabled, your Mac will delay charging past 80% in certain situations

You may need to charge the battery fully if you plan to use the Mac on battery outside without a power outlet. Click “Charge to Full Now” in the battery status menu to start charging.

How To Identify the MacBook model

Before purchasing any parts, you need to know the specifications of your computer.

To identify MacBook year and model follow these steps:

  • Click on Apple logo in the top left corner of the screen
  • In the dropdown menu click on the first item “About This Mac”
  • Under Overview tab locate the information about the MacBook type, size, and year.

For instance, in the screenshot above, I have MacBook Pro (Retina, 13-inch, early 2015).

Now I can locate my laptop in the MacBook Pro 13-inch model table and see that I need 60W MagSafe 2 power adapter.

The table also has an Amazon link which I can use to order the charger I need.

But before you proceed with the purchase, let me answer some commonly asked questions about MacBook chargers.

Using MacBook Air charger for MacBook Pro

According to Apple, it is acceptable to use power adapters with different wattages with MacBooks with a caveat. When using a charger from MacBook Air with a more powerful MacBook Pro expect a longer charging time.

For example, a MacBook Pro 13-inch 2012-2015 requires 60W MagSafe 2 charger.

However, it is possible to use a 45W MagSafe 2 charger (the one that comes with MacBook Air) without any issues. The difference is that the 45W power adapter has less power, and it may not charge fast enough while MacBook Pro is under heavy load.

I have both 45W and 60W chargers at home and found that 60W charger indeed works faster than the less powerful one.

At the same time, I was able to charge with a 45W adapter while watching YouTube videos. So yes, you can use a lower wattage charger with your MacBook.

Using a MacBook Pro charger for MacBook Air

It is perfectly safe to use a MacBook Pro power adapter on lower-wattage models, such as MacBook Air as long as the charging ports are compatible. However, a more powerful charger can wear out the MacBook battery prematurely.

For example, a MacBook Air 2012-2017 model requires 45W MagSafe 2 charger. But it is ok to use a 60W charger of a MacBook Pro with it.

A power adapter with more watts will charge MacBook Air faster.

On the other hand, the faster the battery is charging, the more heat it generates. Eventually, the extra heat may degrade the MacBook Air battery faster.

I have both MacBook Air 13-inch 2014 and MacBook Pro 13-inch 2015 models.

I use their chargers interchangeably, and I never had any issues in 4 years with either one. And I didn’t notice any abnormal battery degradation personally.

Apple chargers for a MacBook Pro

Since the very first model, MacBook Pros have been the go-to laptops for professionals across all fields. Introduced in 2006, they’ve since come in three sizes (13, 15, and 17 inches) and used a variety of processors, video cards, and batteries — all of which have a significant impact on the type of charger being used. So a MacBook Pro 2012 charger is quite different from a 2016 model, for example.

The latest MacBook Pros have been switched to USB-C cables, so if you have a 13-inch version of 2016 and later you’d use a 61W USB-C Power Adapter and if you have a 15-inch version of 2016 and later you’d use an 87W USB-C Power Adapter.

Older MacBooks split in lots of categories. Let’s go from the most recent to way back in time. The 85W MagSafe Power Adapter with MagSafe 2 style connector is for:

  • MacBook Pro (15-inch, Mid 2015)

  • MacBook Pro (13-inch, Early 2015)
  • MacBook Pro (13-inch, Mid 2014)
  • MacBook Pro (13-inch, Late 2013)
  • MacBook Pro (13-inch, Early 2013)

  • MacBook Pro (original)

Where to buy Apple power adapters

Once you know which Mac charger you need, you might be wondering where to buy one. The most no-brainer option is, of course, visiting your local Apple store or ordering from But if you want to save a few dollars or get a special deal, you can also check some other places in the process.

Note: There’s a lot of no-name (or even counterfeit) Apple-like products on the market, which might not work as advertised or, in some cases, damage your Mac. That’s why it’s only recommended to buy Apple power adapters only from large, trusted retailers.

Just a quick look at the 30W USB-C Power Adapter for MacBook Air gives us the following breakdown:

  • Apple’s official website simply lists the Apple MacBook Air charger for 49
  • Amazon lists the same charger with a discount at 43
  • BestBuy matches the 49 standard price but also offers four months of Apple Music for free if you’ve never subscribed before
  • Walmart drops the price to 43 to match Amazon

Right away you can see that Amazon and Walmart offer a better deal, whereas BestBuy would be great for those who haven’t tried Apple Music yet. So make sure to check those retailers (at least) when you’re shopping for your new Apple power adapter.

When to replace your MacBook charger

How do you know when to buy a new charger? Obviously you need one when the old charger fails. But sometimes your adapter might simply start working slower than usual, which is quite difficult to pin down, unless you use robust monitoring software.
