Delivered on time and in good conditions. Working fine, although I could not find much relevant documentation : circuit diagrams, components data sheets, principle of operations. I had to do some reverse engineering.
Received on time, in good conditions. It seems to work properly, but lack of documentation on its actual usage, purpose of the switch and pushbutton.
Very useful item. A little more info on operation would be nice
First the output voltage is not stable. Causing my little device (150 mA consumption) to boot in an endless loop. The measured voltage under load is 4.96V. My powerbank delivers 5.04V. Just to compare.
