Experienced mechanics know that a powerful wheel charger is an essential ingredient for a well-equipped home garage. The Schumacher 6-Volt/12-Volt 300-Amp/200-Amp Wheeled Battery Charger and Jump Starter (SC1400) features 300-amp 12-volt engine start, 200-amp 6-volt engine start, 60-amp boost, and 6A ,2A charge/maintain rates. The jump start packs more than enough power to start most cars, SUVs, and small trucks. The 60-amp boost mode works to quickly add charge to a deeply discharged battery. Fully automatic and microprocessor controlled, the SC1400 automatically adjusts amperage while charging and maintaining. It also offers auto voltage detection, multi-stage charging, float mode monitoring, and reverse hook-up protection. Heavy-duty copper clamps and 4-gauge copper output cables ensure a reliable jump start every time.
