The 10 Best USB-C Power Banks
Special Honors
TravelCard It doesn't offer a ton of added capacity, but this credit card-sized power bank is about as small as they come. Adding to its convenience is a pair of USB connectors, both Type-A and C, that are fixed to the body and tuck away neatly when not in use. travelcardcharger.com
Editor's Notes
October 01, 2020:
USB Type-C utilizes an impressive bit of technology known as Power Delivery to charge compatible electronics considerably faster than a standard Type-A connection. That efficiency, plus the ever-increasing ubiquity of the Type-C port, makes a USB-C power bank a good investment for a lot of people.
If you only need it for phones and other small electronics, the Anker PowerCore Slim A1231 is a very good choice thanks to its small form factor and reasonable capacity. If you have a modern laptop that supports USB PD charging, the ChoeTech B626 might well be the way to go, as it's powerful enough for nearly any laptop available, even a MacBook Pro.
The Zendure SuperTank, Goal Zero Sherpa 22050, and Goal Zero Sherpa 22060 are all similarly powerful, and although they're all pretty expensive, they should last for quite a while. One important feature of the Goal Zero models is their integrated AC outlet, which can accommodate a huge range of devices that don't support USB power. The RavPower PB055, alternatively, is a good choice if you need an AC jack but don't want to spend a fortune. Meanwhile, if portability is high on your list of needs, the Anker PowerCore Redux A1238 and Xcentz 32011 are both worthwhile choices, although the former is still somewhat heavy, and the latter won't be able to recharge most phones more than one full battery cycle.

Depending on what you intend to use these with, you can get away with a simple, lightweight one like the Anker Lite or iWalk. Ultrabook and MacBook pro users will almost definitely need a larger model like the Jackery or the heavy-duty Anker, which put out 45 watts using the Power Delivery specification. The PoderCamino and iMuto Pro appear to be two with the highest capacities. The Sanang is good for those whose phones utilize a fancy, new wireless charging system, while the Luxtude is a good consideration for those traveling to the USA, Europe, or Australia.
