Pro Trainer Soccer

With the optional battery pack you can extend your training sessions with the Pro Trainer beyond 2 hours. If you plug in the external battery pack and run it in conjunction with the internal battery you can get 3 1/2 - 4 hours of training time with your Pro Trainer. Goes where you go. Charges in half of the time - 5-6 hours and has a trickle charge so you can leave it plugged in all the time for optimal battery operation.
