Portable laptop backup power supply

Why should you buy a laptop power bank?

When you’re far from an outlet, these portable chargers will keep your computer alive. Taking care of business doesn’t always happen within range of an outlet. Traveling, working off-site and decamping to a coffee shop are all situations where a laptop power bank could come in handy.

Should you buy a portable laptop charger or a USB power bank?

A portable laptop charger will provide more power in that scenario than a USB power bank. If you want to charge lots of different devices, or a single power-hungry device, for more than a few hours—or if you have critical electronics that require a pure sine wave inverter, such as a CPAP machine—you should get a portable power station.

How many laptop power banks are there?

There aren’t quite as many laptop power banks on the market as there are standard portable chargers, but you’ll still find a fair number to consider. I tested out a handful and can recommend three that cover different needs when you’re far from an outlet but still need extra power.

How many USB ports does a power bank have?

Every large power bank I’ve tested has at least three USB ports, with a mix of USB-C and USB-A, which should cover nearly any portable device you need to recharge — earbuds, phones, tablets, laptops, you name it. In addition to the different plug formats, some ports supply power at different wattages.

What is a portable laptop charger?

Portable laptop chargers aren’t just for laptops. Since they’re power banks with AC outlets, they can provide power to virtually any device that draws up to about 100 watts—such as a room fan, floor lamp, air mattress pump, or ice cream maker.
