The Best Power Bank for MacBook Pro in 2021

A MacBook is the most portable laptop your entire workstation is ever going to get.

Sure, a phone is smaller – but it’s also less powerful and will never be able to run all your programs or offer a comfortable viewing screen.

All laptops are vulnerable to one main requirement though, and that’s battery power.

Whether you didn’t remember to charge before you left for your day or will simply be using it more than can be reasonably expected on a single charge, battery life determines whether or not your MacBook is functional when you need it most.

But since you can’t expect to find power outlets wherever you go, how can you make sure your computer makes all the way through the day with you?

Just like a portable charger for your phone, you can get a portable charger for your MacBook Pro that is designed to hold at least one whole addition charge.

Keep in mind you’ll need a Mac with the latest USB-C tech unless you want to purchase a MagSafe adapter as well, but in this article, we’ll take you through some of the best power banks to keep you on the go.

Quick Summary

  • The RAVPower 26800mAh Power Bank is a solid choice if you need a reliable full charge on the regular. It’s fairly light, charges your Mac quickly via USB-C, and looks sleek doing so. The LED indicator helps you check how much charge you have left to run on.
  • If you prefer to stick with a well-known brand, the Anker PowerCore Speed 20100mAh has slightly less capacity but should still bring your MacBook close to 100%. It comes with a wall adapter that can speed up your normal charging process as well.
  • For those using a Mac with MagSafe, you can plug your AC adapter directly into the Jackery PowerBar 23200mAh for a quick and effective power-up. The power bank also includes USB-C and USB-A if you have other devices to use it with, but is truly one of a kind in regards to the AC support.
  • For the latest 16 inches MacBook Pro, you may consider MAXOAK Laptop Power Bank or Redimp Portable Charger for a cheaper alternative.

Who Should Get This?

A power bank is a great choice for MacBook users utilizing the latest machines and taking them out beyond the range of a power outlet on a regular basis. It will provide a layer of security in case you get a dreaded “power low” notification and keep your Mac running strong all day long.

However, if your Mac has just one or two homes (such as the office and a home workspace), you’re probably fine without purchasing a power bank, since you’ll be near a power outlet almost all the time.

Additionally, older MacBook Pro users will need to consider carefully since using any power bank will require a MagSafe adapter or specialty power bank and these can run fairly expensive.

This power bank offers long-lasting and reliable performance thanks to a Lithium-ion polymer battery cell capable of 1000 or more recharge cycles. It also will charge your MacBook pretty quickly and only takes 6-8 hours to recharge once depleted.

You’ll also get the benefit of multiple devices charging with two USB-C and two USB-A ports. This will work on many different devices but is a recommended cheaper alternative for 16-inch MacBooks.


  • High-speed recharging capabilities – 90 mins to 100%. 
  • Four outputs allow for multiple device charging at the same time.  


  • 600 charge and recharge cycle makes this not as long-lasting of a power bank as other options seen on the list. 

Additional Tips & Resources

Besides purchasing a power bank, there are a few things you can do to keep your Mac from draining the battery any faster than necessary. Here’s a few to get you started:

  • ​Keep the brightness down (it’s good for your eyes too!)
  • Turn off Bluetooth when you aren’t using it. After all, there’s no point scanning for nonexistent devices.
  • Turn off wifi and location services if you don’t need them or are working off the grid.
  • Constantly searching for signal is a huge power drain.
  • Make sure to close programs you don’t need rather than leaving them running in the background.

If you want the convenience of a power bank but the portability and sturdiness of a carrying case for your MacBook, you might be better served by a battery backpack.

These backpacks securely store your Mac but are designed to make charging easy with special ports, pockets, and sleeves to keep everything in order. The eBags Slim Laptop Backpack is a great place to begin looking into these devices.

Buying a Power Bank for MacBook: What to Look For in 2021?


The capacity of the power bank is what determines how much charge it can hold, and is measured in milliamp hours (mAh). You’ll want at least 20,000 mAh to get a full charge, and around 12,000 mAh for about half a charge. Numbers aren’t precise or scaleable due to energy loss during transfer.

The rate at which your computer charges is determined both by the connection and by the output rate, which should be published (though often takes some digging to find) in any product’s description.

Size & Weight

Power banks imply portability, but this isn’t always the case. You’ll notice that the larger the capacity gets, the bulkier and heavier the power bank becomes, which means you’ll need to strike a balance between the two.

If you know you’re already carrying a lot, you may be more inclined to a slimmer model, but if you aren’t afraid of weighing your backpack down, it may be worth it to go for a little extra battery life.


Can A Power Bank Charge A MacBook Pro?

Yes all standard power banks can charge a MacBook Pro, and you just have to make sure they contain at least 20,000 mAh for a full charge as well as having USB-C port like those we covered above. 

How Much mAh And Watts Should The Power Bank Need For 16″ Inch MBP?

If you are just looking for charging without using it, a 40-60 watts power deliver would work jus fine. And if you are looking to charge and use it simultaneously, you would need 100 watts. For mAH you would need at least about 25,000, which is about 20% higher mAH than the 13″ MacBook Pro.  

Final Words

Maybe one day we’ll have MacBooks that can draw power from the air around them, but until then power users are going to need power banks to keep them going on a day to day basis.

Whether you need at least one whole addition charge or just a little something extra to make sure your files get saved before the screen goes black, there are a variety of power banks that can help you make sure that happens.

  1. Thanks so much for the thorough review of these 3 products! Very helpful. Quick question. I understand that these devices will charge my 2019 16” MacBook Pro. However, will a fully charged power bank allow me to use my computer once the internal battery is drained?
    Pat Cassity

    • Hi Pat, not sure if I understand your question correctly. Suppose your MBP internal battery is drained out and you are charging it with a power bank, sure, your Mac should work because the power bank is charging it? About the 16″ what we covered previously were for 13″, for 16″ you would need at least 40-60w power. Learn more above. Thanks!
