Soccer balls, basketballs, volleyballs and so on all have an optimum hardness. The TorrX is a portable electric pump that automatically inflates and deflates balls so that they attain their ideal pressure.
To use the TorrX, all you have to do is start by pushing in its protective end cap to power it up and reveal its needle. Once you insert the needle into the ball's air valve, the pump detects the ball's air pressure and electronically displays it in either BAR or PSI units.
The pump offers auto and manual modes -- in auto mode, you can enter the target pressure and then push the A button, which prompts the TorrX to pump in or release air until the desired pressure is achieved. Manual mode allows you to increase or lower pressure by pressing the + and - buttons.
