GOOLOO GT4000 74Wh Jump Starter

GT4000 Jump Starter

The GOOLOO GT4000 74Wh jump starter is an advanced booster with a capacity of 74Wh (5000 mAh, 14.8V) that delivers a starting current of 800A and a peak current of up to 4000A. This allows it to support gasoline engines up to 12.0L and diesel engines up to 10.0L, setting it apart from many compact devices. In addition to its jump-start function, it also serves as a power bank with fast USB-C PD charging up to 100W, additional USB ports, and a 150W DC output. The device allows for up to 60 starts on a single charge, features a clear 3.2” LED screen, IP65 protection rating, and a battery life exceeding 1,000 cycles.

High power and broad compatibility

High starting power translates to real-world effectiveness. The GT4000 easily handles both smaller cars and large engines, including diesel engines up to 10.0L. This means a single unit can service various vehicles—from passenger cars to SUVs and commercial vehicles. The ability to perform up to 60 starts on a single charge further enhances its practicality and provides greater independence on the road.

Pre-heating technology – a reliable start in winter

The battery pre-heating technology used allows the vehicle to start even in extreme temperatures as low as -40°C. In practice, this means the device prepares the battery for operation before starting, which significantly improves performance in cold weather. This is particularly important for drivers who leave their cars outside in the winter or travel in harsh conditions.

Fast charging and power bank functionality

A USB-C port with Power Delivery support up to 100W enables fast charging of laptops, smartphones, and other devices. Additional USB ports and a DC output increase the device’s versatility, allowing it to replace several different chargers. As a result, the GT4000 works not only as an emergency device but also as an everyday power source.

Clear display and user-friendly operation

The large 3.2-inch LED display shows the charge level, power output, and operating temperature. This gives you full control over the device and lets you know when it’s ready for use. Clear information makes operation easier, especially in emergency situations where a quick response is crucial. It takes about 1.2 hours to fully charge the device using a 100W (PD) wall charger. In practice, this means that with lower-powered chargers, the charging time will be longer, but it remains at a comfortable level. This solution allows you to quickly prepare the equipment for operation and minimize downtime.

Weather resistance and robust construction

The IP65-rated housing protects the device from dust and splashes. Combined with its rugged construction, this means the GT4000 can be used in a variety of conditions—from rain to snowy environments. This enhances its reliability in the field and while traveling.

Safety features

The device is equipped with overcharge and over-discharge protection, fuse protection, and reverse polarity protection. This ensures that using the booster is safe for both the user and the vehicle’s electrical system.
