The Schumacher DSR167 is a 12-volt jump starter that doubles as a 400-watt power inverter and portable power station. It delivers 2250 peak amps, 525 cranking amps and 350 cold cranking amps, enough to start up to 8-cylinder gas and 6-cylinder diesel engines. Two 120-volt AC outlets, a 12-volt DC socket and a 2.1-amp USB port let it run small appliances and charge phones. Owners like its starting power and versatility; some report the included side-connector charger stopped working, so a trickle charger may be needed to keep it topped up.
