Every car owner dreads the day when their car’s battery just won’t start. The situation gets worse when you’re alone and there’s not another car in sight. Luckily, you can be prepared with the STANLEY 1000 Peak Amp Jump Starter with Compressor. This device packs 500 amps of instant starting power, as well as 1000 peak amps, offering a convenient, portable way to jump-start your battery without relying on another vehicle. All you need to do is connect the hook the clamps to your battery, turn on the switch and start your vehicle. A built-in safety system sounds an alarm if you connected the clamps incorrectly. This jump starter also has a built-in USB port, highly useful if you need to charge your phone, and the 120-psi compressor can help with low tires. With enough power to jump-start your car, truck, motorcycle, boat, RV or tractor, the STANLEY Battery Jump Starter is ideal for everyday use or roadside emergencies (extension cord NOT included). Note: The unit should be charged every 30 days if it is not being used. If it is used, it should be charged immediately overnight.
