8 of the best external laptop battery chargers you can buy in 2018

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 2 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.

1. MAXOAK 50000mAh 5/12/20v

This hefty external battery works with most laptops (but not Macs!) and features 6 output ports:

  • One 20V/5A port for laptops
  • One 12V/2.5A port for digital cameras
  • Two 5V/2.1A and Two 5V/1A for smartphones and other battery-charged devices

Multiple devices can be charged at once, which is very handy if you have a laptop and a phone that need juice at the same time. Or if you too have friends that never bring their own power banks and always rely on you.

And at 2.77 lb (1.2 kg) it has a decent weight, although you wouldn’t want to take it jogging.
