Dedicated grease monkeys know that a powerful wheel charger is an essential ingredient for a well-equipped home garage. While many people prefer fully automatic chargers, others want complete control over the charging process. For these hobby and professional mechanics, the answer is a Schumacher manual wheel charger. The Schumacher Electric SC1445 2-in-1 6-Volt/12-Volt 250-Amp Manual Wheeled Battery Charger and Engine Starter features a 135-minute timer that allows users to control every facet of charging and gives them multiple charging options. It features a 250-Amp (12-Volt) engine start, which is enough power to start SUVs, trucks, and other large engines. It also features three boost modes-50-Amp (12-Volt), 25-Amp (12-Volt), and 25-Amp (6-Volt)-for quickly adding charge to a deeply discharged battery. The SC1445 also includes a 10-Amp (12-Volt) charge mode for basic charging needs.
