The GBX155 was designed for people who have never touched jumper cables. Spark-proof technology means the clamps won't arc when you connect them. Reverse-polarity protection detects if you accidentally attach red to black and blocks current flow, preventing damage to your vehicle or the unit. Thermal management keeps the battery safe during use and charging. Status LEDs confirm proper connection before power flows. You get the confidence of professional-grade safety features in a unit anyone in your household can operate.

The GBX155 delivers 4250 peak amps, enough to jump gasoline engines up to 10.0 liters and diesel engines up to 8.0 liters. That covers most cars, trucks, SUVs, vans, motorcycles, boats, RVs, and ATVs on the road. If your engine falls within those specs, this unit handles it. The heavy-duty clamps grip securely on battery terminals of all common sizes. One full charge provides multiple jump attempts, so even if the first crank is sluggish, you have power in reserve to get the engine turning.

Peak Amps: 4250A. Engine Support: Gas up to 10.0L, diesel up to 8.0L. USB-C: 60W in/out. Flashlight: 500 lumens, 6 modes. Includes: Clamps, USB-C cable, 12V-to-USB-C cable, bag, guide.
