GOOLOO GT4000S Jump Starter

The GOOLOO GT4000S is a 74Wh (5000mAh, 14.8V) jump starter delivering a peak current of 4000A and a starting current of 800A during starter motor operation. It supports gasoline engines up to 12.0L and diesel engines up to 10.0L. The device features a 100W USB-C Power Delivery port, 150W USB and DC outputs, an IP65-rated waterproof housing, and a 3.2" digital screen, making it practical for use both inside and outside the vehicle.

Start-up Parameters Tailored to Real-World Situations

The peak current of 4000A represents the maximum energy pulse needed to overcome resistance when starting the engine. The 800A starting current is supplied while the starter motor is turning, the most demanding moment of the process. This combination ensures effective vehicle starting even with a significantly discharged battery, providing energy exactly when most needed.

Performance and Reliability

The 74Wh battery allows up to 60 start attempts on a single charge, offering great flexibility without frequent recharging. The device has a lifespan exceeding 1,000 cycles, ensuring long service life. It is suitable for emergency support as well as regular use, such as servicing multiple vehicles or professional work.

Fast Charging and Ready for Action

Equipped with a USB-C port supporting 100W Power Delivery, the GT4000S charges fully in about 1.2 hours, minimizing downtime. In emergencies, approximately 5 minutes of charging provides enough power for a startup attempt, which is practical when access to power sources is limited.

Versatile Power Source

The GT4000S also functions as a power bank. The 100W USB-C PD port can charge laptops and other high-demand devices, while USB-A ports power smartphones and mobile accessories. The 150W DC output supports automotive equipment requiring higher power, allowing simultaneous multi-device use on the go.

Durability and Operation in Various Conditions

The IP65-rated housing protects against dust and water, enabling use in adverse conditions. It operates reliably within a temperature range of -20°C to 60°C. With a standby time of up to 24 months, the device can be stored in a vehicle and remain ready without frequent recharging.

Ease of Use and Additional Features

The 3.2" screen displays charge level and operating parameters clearly. A built-in LED flashlight enhances usability in low light. The Boost button allows forced start for deeply discharged batteries. The package includes jumper cables, USB cables, a 100W car charger, a cigarette lighter adapter, and a carrying case, making the device ready to use immediately.
