Best value for money – hands down the best power bank on the market
I returned it for a refund after a short while because it wouldn't charge.

It really is pocket-sized – exactly what I needed (10,000 mAh version)
The iPhone 13 mini charges quickly
It doesn't switch off like other brands do
The LEDs are more than enough to give you a quick overview of the charge level and charging speed
