Lol, this power bank has already been on the market under a handful of different names. I've personally reviewed it when branded as Hopetrek, but I've also seen it sold as Amegat/Aukey, RAVPower, Vivan, RAVPower, LOGiiX, Maxpower, Euker, Powdeom, Joway, evatronic, Poweradd and as the other OP said, Hoco, all with slightly different capacity ratings.

It's a decent power bank, but will over-negotiate power on the two type-C ports. It'll tell BOTH devices they can draw 140W (280W total) but will go into protection mode and shut off the outputs if they collectively draw over 152.5W.

It suspiciosly looks he same as hoco q17 lol
