Workers with arm or back impairments can use the Electric-Powered Automotive Jack to raise (with the push of a button) one side of a vehicle 12-17 inches to allow for tire maintenance. The device runs off the vehicle's 12-volt DC battery via an adapter at the end of a long electrical cord that plugs into the cigarette lighter or 12V outlet. Depending on make/model, maximum lift capacities range from 1 to 5 tons. Most have a built-in circuit breaker to protect the vehicle's wiring from overload, slipping-prevention safety features, tire-inflation capability, and storage case.
