8 of the best external laptop battery chargers you can buy today

8 of the best external laptop battery chargers you can buy today

Laptops have become essential devices in the lives of many of us, especially for people that are highly mobile. Regardless if we’re traveling or going on a business trip, we tend to take our laptops with us. And ever so often we run out of battery power. Sometimes during some highly important moments such as letting the boss know that you’re going to be two days late from the vacation.

Actually, laptop batteries get less performance as they age. So a laptop that would run for 4-5 hours when new, will end up working for just 30 minutes after a few years of use. For this and many other reasons, external laptop batteries can come in very handy.

Instead of squatting next to an airport plug as people pass you by, you can very easily take out a portable battery and charge your laptop as you’re comfortably sipping a drink at the cafe bar. Or how about binge-watching the last season of Game of Thrones on a mountaintop? Yes, you can do that too, with one of these external laptop batteries.

Although not the most powerful or cheap (compared to output) item on the list, this is definitely one of the lightest at only 1.08 pounds (490 g). And considering it’s size of 6.7″ x 3.1″ x 0.8″ (17cm x 6.7cm x 2cm) it’s also one of the slimmest laptop chargers you can find. Unlike many power banks on this list, this one can actually fit in a pocket (albeit not a very tight one).

It charges most laptop models including the often troublesome Macs using the Type-C plug that matches the MacBook’s original 30W charger. However, a Type-c charger is not included in the packages and must be purchased separately.

Anker is one of the top brands when it comes to power banks. This model is a good fit for anyone that wants to power their laptops, especially MackBooks or other USB Type-C devices. One of the features that stands out for this battery is it’s fast charging time.

Although not as famous as other brands in this list, AIVANT, delivered a sound product in the KP-899. It’s one of the few powerbanks that’s been made primarely for laptops. With its high-end capacity, it can power almost all laptop models, with the exception of those that operate with a DC current over 10A/120W.

One of the most appealing features of the AIVANT KR-899 is the fact that it comes with two AC outlets. So if you’re into activities that require the use of two laptops at the same time, then this is could be one the best alternatives. Besides the 2 AC outlets, it also features four USB ports (5V/2.1A*2, 5V/1A*2) and one 12V output port for jacks.

Another handy feature of the AIVANT KR-899 is the solar input port. This means that you can charge it using solar panels, which is very useful if you’re planning long trips off-grid.

In terms of size, it comes in at 7.9″ x 5.7″ x 1.8″ (20cm x 13.7cm x 4.5cm) and it weighs 3.31 pounds (1.5 kg). So it’s definitely not the most nimble on the list.

mAh/$: $0.004761

  • 2 AC outlets
  • Can be charged by solar energy
  • Comes with a sturdy case
  • Heavy and bulky
  • Cannot be taken on planes
  • Does not support laptops with DC current over 10A/120W
  • Does not support pass-thorough charging

This concludes our list. Now, depending on your specific requirement, some of them might be better than other. So we here’s our take on the best choice for some of the most popular needs:

Before purchasing any of these it’s wise to make sure that your laptop is fully compatible with the external battery you’re interested in. So check details such as laptop model and power input specifications. Most of the time you’ll be able to figure it out by reading the product page details. But sometimes you’d need to get in touch with the supplier. This short research can save you loads of time and nervs in the unfortunate event that you’ll order an incompatible charger. It pays to do your homework!

This being said, do you know of any other external laptop battery that is so good that it should be included in our list? If so, please let us know in the comments and we’ll take it into consideration. If we consider it to be good enough, we’ll add it to the list!
