Build quality is above average. I have complaints regarding interface/firmware - it's not clear when the power bank is charged. Sometimes there is a progress bar with percentage, sometimes only a progress bar, sometimes nothing. I need to connect a USB power meter to figure out whether charging works or not. I haven't checked with my USB power meter how much amps are being put inside yet but charging speed seems decent. Never discharged more than 20% capacity of the cells though.
Discharging is OK but I've pushed only 1A through it. I tried some Samsung (S9 I think) with a brand new quality 2.4A cable - it didn't charge at all. Second cable didn't work either. Guessing some issue with QC. I'm using 3500mAh Samsung unprotected cells - no issues with warming up so far.
In a few weeks I'll have a new phone with 18W charging, we'll see how that goes.
Obviously the product needs a proper teardown.
