The Power Dome Jump Starter gives you reliable, portable power wherever you need it – on the job site, at the cabin and on the road. It'll jump start your car, charge your digital devices and even top off tire pressure with the onboard compressor. 24" jumper cables with 900 peak amps of power pack enough juice to start nearly any vehicle. The 400-watt inverter powers a laptop, small heater or blender, and there's a USB port to charge your phone or tablet. When it's time to recharge, just plug the Power Dome into your 110-volt home outlet or 12-volt car plug. Feel the power!
