FAQ:

Q: What is an ultraslim power bank?

A: This ultraslim power bank fits in a wallet or pocket, can charge most phones to at least a third full, and is available in Lightning, Micro-USB, and USB-C versions.

Q: What is a USB Power Bank and why do you need one?

A: Due to the unfortunate fact that battery technology has failed to keep up with the processing power of modern devices, USB power banks have become an increasingly popular way to help phones and tablets get through the day.

Q: What features do you look for in a power bank?

A: Built-in cables: We preferred that the power banksโ€”especially the smaller, low-capacity modelsโ€”have some type of built-in cable. This feature is indispensable when well integrated because it reduces the number of cables you have to carry around and (eventually, inevitably) disentangle from the rest of your stuff.

Q: How much does a power bank charge from empty?

A: It has the lowest capacity of any power bank weโ€™ve testedโ€”itโ€™s able to charge most phones only to around 30% to 50% full from emptyโ€”but itโ€™s unmatched in weight (2 ounces) and size. Itโ€™s bigger and thicker than the average credit card but not by much, fitting easily in a wallet or pocket.
