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.

Nous l'avons reçu aujourd'hui ça semble un très bon produit, je l'ai utilisé pour charger un téléphone très efficace... le câble intégré une très bonne idée et le fait qu'on puisse voir la batterie restante c'est vraiment bon .. le produit est solide compacte parfait pour voyager

Great price. But plugs are very hard to push in.

Great build quality, works well!

I love the extra space for power adapters.

juste parfaite
