Awesome 5000mah power bank that weighs less than 90g (3.14oz) - Nitecore NB Air

I recently picked up on AliExpress a Nitecore NB Air power bank. 5000mah. About the same size as an Apple TV remote. Less than $40.

89g (3.14oz). USB-c. Great ultralight piece.

Previously I was using the NB10000 that most people have, but this is almost good chunk of weight savings, and can fully charge an iPhone.
