This ultra-thin power bank I tested is a must-have travel gadget (and it gets a price cut for Amazon Prime Day)
Briefly

It's small and thin, yet robust, and delivers on all its promises. I've tested portable chargers of all sizes, but recently I had the chance to get my hands on the Auskang 5,000 mAh power bank, an ultra-thin device that's about the same thickness as a stack of coins, and it didn't disappoint.
The first thing that's utterly striking about this power bank is how thin it is. It's really thin, much thinner than my iPhone, and about the thickness of a few credit cards or a few coins.
