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.
