16 watt max discharge. Charge also caps at a little over 16 watts, this could also be due to the phone charger. Paired this board with a 50Ah 3.7v battery, and it can charge my laptop all day! Unit sometimes produces a squealing noise, but mostly is quiet, unless you put your ear on it you can’t hear a pitch. Capacity indicator works good. Starts blinking when the voltage approaches 3.2v, and then stops to protect the lipo battery. Max charge by board is 4.2v. It supports fast charging like my picture. Step up down conversion is about 90% efficient... so 10-12% percent loss, no big deal I think. Over temperature is nice, but I have not tested. Supports dual charging, but only at 5v.
It has USB-A port with 5th contact for Dash charging (One+ phones, dash and-or warp compatibles,with original cable).
