It fits better in a laptop bag than a pocket, but it recharges the fastest of any power bank we tested and can charge everything from smartphones to laptops. It also works as a USB hub.

The ZMI PowerPack 20000 can charge phones, tablets, and most laptops. It doubles as a hub, adding extra ports to your laptop, and it weighs less than a pound.

This power bank is about the size of a small paperback but can charge a wide variety of devices, whether you’re traveling or riding out a blackout. The two USB-A ports can charge phones and tablets, but the USB-C port can also charge many of the latest laptops.

If you need to charge your watch away from an outlet and don’t want to carry a charging cable, this power bank can charge an Apple Watch around seven times on the integrated charging pad. The included dock holds the power bank up, so it doubles as a stand.
