PowerMax PMJS 2000 Lithium Jump Starter – 2000 Peak Amps, Lightweight Portable Booster

The PowerMax PMJS 2000 Lithium Jump Starter is built to deliver reliable, on-the-go power when you need it most. With 2000 peak amps and 1000 cranking amps, it’s strong enough to jump-start vehicles up to V8 diesel engines, while also providing auxiliary power for RV slide-outs, awnings, and 12V tongue jacks when coach batteries are depleted.

Unlike bulky lead-acid jump starters, the PMJS 2000 uses a lightweight lithium battery that is 80% more powerful and holds its charge up to 10x longer. Weighing less than 5 lbs, it’s compact yet powerful, offering up to 40 jump starts per charge on 4-cylinder engines.

Equipped with built-in safety protections, heavy-duty clamps, and versatile charging options, this jump starter doubles as a portable power bank with USB and DC outputs—making it ideal for RVs, trucks, cars, and marine use.
