Nyko has come out with two accessories for the PSP. First is the Charger Case (left), in which your lovely PSP fits snugly into a neoprene lining. Both items use a lithium-ion battery. The battery works by having the PSP battery charge first. When it's in use, the charger's battery is used before that of the PSP. The Charger Case adds 7 extra hours. Both also have an anodized aluminum exterior, how fancy. In comparison, the Theater Experience (right) only adds 5 extra hours. It also provides hi-definition stereo speakers and an adjustable viewing stand. However, questions still remain in regards to the weight and actual sound quality of the speakers.
Charger Case $69.99
Theater Experience $79.99
