The 4 Best USB Power Banks for Phones and Tablets 2022

Our pick

Zendure SuperMini 20W

This is the smallest and lightest 10,000 mAh power bank we’ve tested. It has USB-C PD and USB-A ports, it comes in several colors, and its rounded edges make it easy to slip into a pocket.

The Zendure SuperMini 20W is about as small and lightweight as a power bank can possibly be while still offering enough capacity to juice up most smartphones up to three times. Its USB-C Power Delivery (PD) port can charge most handheld devices (and recharge the power bank itself) at top speed with the included USB-C cable and a compatible wall charger (the one that came with your phone will work). The USB-A port can handle any older, non-USB-C devices you might have kicking around, too. The SuperMini’s rounded edges make it easy to hold and slip into a pocket, and unlike most power banks, it comes in a wide range of colors: red, green, black, silver, blue, and pink.

Anker PowerCore III Fusion 5K

This palm-sized power bank charges your devices on a USB-A port and a speedy USB-C PD port, and recharges itself via the USB-C PD port or through a fold-out AC plug.

Buying Options

*At the time of publishing, the price was $40.

The Anker PowerCore III Fusion 5K is handy if you want a single, reliable charger that you can plug in the wall to charge your devices overnight and then pack up and carry with you during the day. Its 5,000 mAh capacity is half that of the Zendure, but that’s still enough to fully charge most smartphones more than once (and at 6.4 ounces, it’s just as lightweight as our top pick). The Fusion 5K recharges quickly via its USB-C PD port or fold-out AC plug—most models we tested have just one or the other—and it offers fairly fast charging for two devices at a time on the USB-C PD and USB-A ports. If you want a power bank that doubles as a wall charger, this is the best option we’ve found.
