ben man you rock i know you can do it
Oh, so you want a battery pack? I mean it won't be a handheld still, I don't think a "handheld" with the controller built in for the purpose of holding in your hand to play is a realistic project, just adding a battery and such is easier.
Ya something like that but maybe still an all in one unit but maybe like a detachable controller
Maybe he could use a Tenergy battery pack.
Would have to be a big pack. Apparently the slim uses 80 W while gaming.
