Nothing Spoils A Road Trip Faster Than A Flat Tire. When Roadside Service Can’t Get There Soon Enough, Reach For The Powerbuilt 12V Electric Jack And Tire Inflator. Just Position It Under Your Vehicle Lift Point, Plug It Into A 12V Outlet, And Press The Button. Like Magic, The Lifting Post Extends And Raises Your Vehicle Up To 14 Inches High. With A 1-ton Lift Capacity, It Has More Than Enough Power To Lift One Side Of Almost Any Passenger Vehicle. And If Your Spare Tire Is Low On Air, Just Use The Built-in 115 PSI Inflator To Air It Up To Proper Pressure.
