We considered 18 USB-C battery packs and tested seven contenders over dozens of hours, and the Tronsmart Presto 10400mAh Type-C Battery Pack is the best power bank to charge USB-C–equipped smartphones and tablets on the go. The larger Anker PowerCore+ 26800 PD Battery Pack and Charger Bundle, which provides twice as much power, is our pick for keeping a USB-C–powered laptop charged. However, if your devices don’t have USB-C ports—that group includes many Android devices, and all iPhones and iPads—and you don’t plan to buy the latest and greatest Android smartphone in the next few months, our guide to standard USB battery packs offers more variety at lower prices. We also have a guide to portable AC power banks if your laptop isn’t USB-C powered, or if it needs more power than the current generation of USB-C batteries can provide.
