I ordered 2 ac adapters from Retrogamecave. 1 for my Duo-R and the other one for my Tg16 cd. They both work really great, but I will tell you the actual lenght of the wires are really short compared to the original ac adapters. Their only 44 inches in lengh and the originals are about 8 feet in lengh. A fairly big difference but the Retrogamecave ac adapters do seem to run a hell of a lot cooler and from what I read are also more efficient compared to the original ac adapters. Their worth buying but I figured Id give you a heads up on that ...
