Product review (5 stars): TPower increible customer service.......
On June 6 I order this charger, but sadly did not work with my mother oxygen machine, I contact T- power and a day after they send me a email, asking to give them all the information I have about the charger, they also ask me if I can take pictures which I did, a day after that they send me another email telling me that a new charger was on the mail I received today, and it worked, what a custumer service I will recommend this company to anybody who would ask or any or my friends or family.

Thank you Mr. Joe you guys are incredible, again great customer service.
