GOOLOO GT4000S is a powerful jump starter with a 74 Wh capacity, delivering a 4000 A peak current and a 800 A starting current for reliable starts even with a severely discharged battery. It supports gasoline engines up to 12.0 L and diesel engines up to 10.0 L, features 100W USB‑C Power Delivery, IP65 protection, and a clear 3.2" display – ideal for the car, workshop, and travel.
The GOOLOO GT4000S jump starter is designed for real roadside emergencies as well as regular use. The combination of 4000 A peak current (maximum pulse) and 800 A starting current (during cranking) helps start a vehicle even when the battery is in poor condition or deeply discharged. Practical features such as the Boost button and LED flashlight make it easier to use, especially in the dark or in bad weather.
With a 74 Wh capacity, it can handle up to 60 start attempts on a single charge, and its lifespan of over 1,000 cycles makes it a dependable long-term helper. The rugged design with IP65 protection and an operating range of -20 to 60 °C allows use in both winter and summer. Another advantage is the long standby time of up to 24 months, so it can stay in the car as peace of mind.
The GT4000S also works as a high-performance power bank. 100W USB‑C PD is suitable even for charging laptops, while the USB outputs handle phones and accessories. Charging the unit itself is fast – to full capacity in about 1.2 hours, and in an urgent situation roughly 5 minutes of recharging may be enough for a start attempt.
