Home Depot offers the Schumacher Battery Extender 12-volt 750-amp Car Jump Starter for $49.88 with free shipping. That's $28 under the lowest price we could find for a similar Schumacher jump starter elsewhere. It jumps 4-, 6-, and 8-cylinder vehicles and features a 2-amp USB charging port, 12-volt DC power port, LED light, 150 PSI air compressor, and 8-gauge cables with spark-resistant clamps.
