Seems good quality, Since receiving and fully charging, I have cycled it empty to full 4 times and measured capacity. I am getting 33.5 to 34 Wh out so lives up to 37Wh capacity with about 90% out. 48.5 to 51 Wh in to recharge it so roughly around mid 70s efficiency on charging. I get close to 2A @5v in from a pd/qc usb supply also charging my phone I get the same ~2A @5v out. On the downside I would have preferred a usb-c out port rather than the built in cable. Also to be aware of is that the usb-c port in input for charging only it does not provide usb-c out.

Pro: Included USB C is very convenient Small - compact enough for a phone and this in your pocket Display for battery percentage Two outputs Two different inputs Cons: Doesn't fast charge my S20 FE I would've preferred Micro USB as another charge port. Overall I would recommend this to anyone.

Good charger but it doesn't have 3 input like the description says. 2 input and 2 output. It's also a bit heavy.

elle est vraiment pratique et je suis contente d'avoir dénicher cette batterie

Parfait pour mon utilisation
