Enough for a serious workout. A recharger comes standard with the purchase of any model. All functions are controlled by a single electronic control panel. In addition to the control functions it includes a battery charge indicator, and an automatic time delay so you can walk to your playing position after start-up. The Wilson Portable Ball Machine is backed by a one-year warranty covering both parts and labor.
Extended warranties are available.
A keychain-sized remote unit starts and stops the ball throws, and also starts and stops the oscillator to position ball throws anywhere across the court. This feature allows the user to have the machine hit one forehand, then one backhand alternately. It includes a rugged carrying case with strap, and its own battery charger. If you have an ac outlet on the tennis court this option will allow you to plug the machine into the outlet. Please note that the battery must be fully charged to use the ac power supply.
