I'm looking to get a power bank in the 20,000 mAh bracket. It needs to be able to be recharged over USB-C as that's what our phones use and I'd like to keep things neat like that. I'm not afraid to spend money but only if I know it will be a quality product, however it's a bit of a minefield and the tech is moving fast. Current contender is an Anker PowerCore+ 21000, but it's not ideal by the looks of it. Any advice or recommendations would be appreciated.
