GOOLOO GP4000 74Wh Jump Starter

The GOOLOO GP4000 74Wh is a portable jump starter for 12V vehicles, equipped with a 74Wh battery, 800A cranking current, and 4000A peak current. The model is designed to start most gasoline-powered vehicles and diesel engines up to 10.0L, and can perform up to 60 starts on a single full charge. In addition to its jump-start function, it also offers fast charging via USB ports, a 15V/10A DC output to power select car devices, and a built-in LED flashlight with Normal, Strobe, and SOS modes, which can operate for up to 96 hours. All of this is housed in a compact case, making the device ideal both as emergency car equipment and a practical power source while traveling.

High starting power for everyday and emergency situations

The GOOLOO GP4000’s primary function is to provide quick assistance when dealing with a dead battery. An 800 A jump-start current and a maximum current of 4000 A translate into real help when the car won’t start in the morning, after a long period of inactivity, or while on the road. The device is compatible with 12V vehicles and is designed to support most gasoline-powered cars and diesel engines up to 10 liters. This range makes it useful not only for typical passenger cars but also for larger vehicles used on a daily basis.

Ports that enhance the device’s functionality

The GOOLOO GP4000 does more than just start your vehicle. The device features a 15W USB-C input and several practical outputs, allowing it to serve as a power source even outside of emergency situations. It features a 15W USB-C port, a 5V/2.1A USB output, a Quick Charge port supporting 5V/3A, 9V/2A, and 12V/1.5A standards, as well as a 15V/10A DC output. This allows you to charge smartphones and other compatible mobile devices, as well as power select car accessories requiring 15V/10A, such as compressors, car vacuums, or other devices compatible with this specification. It is this variety of ports that makes the device useful even when you don’t need to start the car.

BOOST function for more difficult starting situations

The jumper cable module features a BOOST button that assists in starting the vehicle in more demanding situations. This is a practical solution when the standard starting mode proves insufficient. The presence of such a module enhances ease of use and provides the user with additional support when a quick response and easy access to key functions are essential.

Copper clamps for better conductivity

In the product specifications, the manufacturer highlights the use of copper in the cables and clamps. This is important for a jump-start device because good electrical conductivity improves performance and reduces energy loss during engine startup. In practice, this means a more secure connection to the battery and greater reliability when the device needs to perform its most critical task. Sturdy metal clamps are also simply more convenient to use and hold up better when regularly carried in a car.

An LED flashlight that comes in handy not just around the car

The built-in LED flashlight is one of those features that quickly prove to be truly useful. It makes it easier to connect wires after dark, check components under the hood, or illuminate the area around the car while parked. You can choose from Normal, Strobe, and SOS modes, so the device can serve not only as a work light but also as additional support in emergency situations. The manufacturer claims the flashlight has a runtime of up to 96 hours, which increases the device’s practicality during travel, camping, and unexpected incidents on the road.

A compact design that’s easy to keep on hand

The device measures 22.81 × 9.96 × 3.81 cm and weighs 821 g, so it can be easily stored in a trunk, glove compartment, or case. This size means the GP4000 doesn’t take up much space, yet remains easily accessible when you really need it. This is important because emergency equipment should not only be effective but also convenient to store and transport. The GOOLOO GP4000 can operate in temperatures ranging from -20°C to 60°C. This is a key feature for a car device, as operating conditions can vary significantly depending on the season.
