This truly versatile inflator can be used anywhere. With three different power sources; you can use it in the home with the mains electric power, plug into an in-car socket using the 12V adapter, or even use the 18V lithium-ion battery if you're on the go outside. Ideal for car and bike tyres, mattresses, footballs and more, the high volume output gets the job done quickly. Complete with a digital pressure gauge and automatic shutoff technology, this inflator brings set-it and forget-it, peace of mind. Pump, pump, pump it up.
