I use it for charigng my 36V Li Ion e-bike battery from (solar charged) lead acid battery. I also intend to use it for charging Ryobi ONE+ batteries that I use in my lawn mover for instance. It works like charm and I will order second one... USB port works fine. I did not yet come to test the BlueTooth. I wish it would also show how much energy was put to the battery (mA/h).
