Dead on arrival. Junk. Wait - I take it back - the little red LED works great, if that's your intended sole purpose for this device. It also got warm like a normal charger and it did not trip a breaker - if you only intend to warm your hand on it throughout the day. ...just no output voltage. I tried it on 2 different phones to no avail. BTW - A generic micro-USB charger is a micro-USB charger - dropping Samsung name in description is lame attempt to add a false appearance of quality. Whew - I feel better now.
