Jump starter for large engines

The GOOLOO GT4000S-RED delivers 4000A peak current to start 12V gasoline engines up to 12.0L and diesel engines up to 10.0L. Its 24000mAh capacity supports up to 60 jump-starts on a single charge. The unit is built for drivers of RVs, trucks, SUVs, tractors and boats who need reliable emergency power.

Replaces jumper cables and slow chargers

Unlike traditional jumper cables that require a second vehicle, this pack works standalone and reaches full charge in 1.2 hours via the included 100W charger. A five-minute top-up provides enough energy for one start. It is not suited for 24V systems or engines exceeding the stated displacement limits.

Sustained output with safety monitoring

The 3.2-inch LED screen shows real-time status during extended use. IP65 water resistance and 94V0 flame-retardant housing protect the internals in harsh conditions. Three USB ports supply up to 100W PD, 65W for laptops and 2.4A for accessories while the unit holds charge for 24 months in storage.
