4000A jump starter with 26800mAh capacity

The GOOLOO GT4000-Hot delivers 4000A peak current and a 26800mAh battery to start 12.0L petrol or 10.0L diesel engines. A 3.2-inch LED screen shows real-time status while ten protection systems prevent misoperation. The unit recharges from empty in 1.2 hours using the included 100W charger, and five minutes of charge provides enough power for a single jump start. IP65 water resistance and 94V0 flame-retardant housing add durability for roadside use.

Cold-weather drivers and multi-device users

Pre-heating technology enables reliable starts down to -40°C, making this model suitable for extreme winter conditions. The 65W USB-C output fast-charges laptops and the 100W two-way input keeps the pack ready between trips. Buyers who only need occasional jump starts for smaller engines or who do not require laptop charging may find a lower-capacity unit more economical.

4000A peak current rating

The 4000A peak figure determines whether the starter can crank your specific engine displacement. Verify that your petrol engine does not exceed 12.0L or your diesel engine 10.0L before purchasing.

Questions about this item

Does my vehicle need a specific engine size or voltage to use the GT4000-Hot jump starter?

The unit is designed for 12 V systems and can start gasoline engines up to 12.0 L or diesel engines up to 10.0 L, covering most cars, trucks and SUVs.

Will the jump starter still deliver its 4000 A peak current if my car battery is completely flat in freezing weather?

Yes, the built-in pre-heating technology activates automatically down to -40 °C, warming the internal cells so the 4000 A output remains available even in extreme cold.

How can I confirm the GT4000-Hot is ready to jump-start after I recharge it?

The 3.2-inch LED screen shows real-time battery percentage and status icons; when it reads 100 % and no fault symbols appear, the pack is fully charged and ready for use.
