The brand says "seneo". Its input is 5 volts and 2 amps. And its output is 10 watts Max. I have it plugged in and it seems to work like it should, except that it's not charging my phone. What it's doing is when I place the phone on top of the charger (and I tried to make sure it's perfectly lined up) then my phone will begin to charge for only a split second but then light on the charging pad will slowly flash.
