JS395B 3000A Heavy Duty Jump Starter

With high, safe current output, the 395B instantly starts heavy-duty trucks even at -40°C, so extreme weather won’t slow you down, whether you’re at the roadside or in a remote location.

Built with vehicle-grade 60°C high-rate LiFePO4 cells in a sturdy, impact-resistant casing, the 395B delivers stable, reliable power while minimizing the safety risks common in traditional lead-acid units.

Engineered for durability, its LiFePO4 battery cycles over 3000 times, allowing you to jump start more than a hundred times on a single charge, year-round—all in a compact, portable design you can carry and operate effortlessly.

A DC 29V/5A input charges the jump starter in just about 1.3 hours, keeping it ready for action. The built-in handle and lightweight design make it easy to grab and use—no helpers, no wasted time.
