I purchase another controller think it charge two of the normal PS3 controller and two move controlelr -- but it only charge one move and one nav controller . this one will charge 4 of any combination of move or nav controller . I also believe it hold they better than my other controller , provide positive feedback as to the charge status -lrb- and when it be do -rrb- and have a power button -lrb- my other one do not and thus be always drain electricity -rrb- .
