GOOLOO GP4000 Jump Starter 4000A Peak – All Gas & Up to 10.0L Diesel, USB-C Power Bank

Power on demand with the GOOLOO GP4000

Engine-start confidence arrives in a compact, rugged pack. The GP4000 delivers up to 4000A peak to help start gasoline engines and diesel engines up to 10.0L, even when the battery reads very low. In practice, a quick press of the BOOST button can nudge a stubborn engine back to life, letting you continue your day without a tow.

Beyond jump-starting, this device doubles as a portable power bank. It features dual USB ports (one fast-charge capable) and a USB-C port for efficient recharging. The unit remains easy to carry in a glove compartment, trunk, or backpack, ready to power your devices or revive a vehicle in an emergency.
