The HO Sports iPUMP Electric Inflator eliminates the hard work of inflating or deflating your favorite tube or any other inflatable with an H3 valve. With the iPUMP you can save your energy for paddling or playing rather than wearing yourself out by manually pumping up your inflatable with its hand pump. It can be powered by the cigarette lighter in your car or boat and has a 2-stage motor that will shut off automatically once it has reached your requested PSI. Get yourself a HO Sports iPUMP Electric Inflator and save your energy for the water!
