Built for the Moments That Matter Most
Unmatched Power
Starts V8 trucks and diesel engines in subzero cold — 3000A peak delivers instant confidence when you need it most.
Power That Lasts
The advanced LiFePO₄ battery maintains its charge for up to 12 months in standby, with a tested 40% remaining capacity, and delivers 1,000+ reliable cycles over its lifetime which equals 10 years of reliable starts.
Maximum Safety
10 smart protections keep every start spark-free. So nothing happens if you connect it wrong. It’s completely spark-free and foolproof.
Patented Heavy-Duty Clamps
Reinforced, detachable 4ft clamps for secure and safe connections. Copper-core grip won't slip or spark like cheap clamps.

Perfect little lifesaver. I used it six times in two days when my old battery kept dying, and it never failed once
5.0
Finally, a jump starter that actually holds a charge. Left it in my glove box for months and it still fired up my SUV instantly
How It Works
Firmly insert the smart jump cable into the jump starter’s output port. The indicator light will turn on, placing the device in standby mode.
Connect the red clamp to the battery’s positive (+) terminal, then the black clamp to the negative(–) terminal. Ensure both clamps have clean, secure contact with corrosion-free metal surfaces.
Wait for the green indicator light on the smart clamps — this confirms a proper connection. Then start your vehicle.
After the engine starts, disconnect the clamps in reverse order - black first, then red and unplug the cable from the jump starter.
Engineered for Real Emergencies
Most jump starters fail when you actually need them. The PowerX won't leave you stranded. It starts V8 trucks and diesel engines in subzero cold, won't catch fire like cheap lithium batteries, and lasts 3x longer than competitors. This is the tool that gets you home when everything else fails.
