Engine Power You Can Count On
Few things are more frustrating than being stranded with a dead battery—especially in a large vehicle. The GOOLOO GP4000 offers peace of mind with serious starting power, capable of reviving even high-displacement engines in seconds. Whether you drive a pickup truck, SUV, van, or diesel vehicle, this unit ensures you’re never left waiting for a tow.
Portable Power Bank for All Your Devices
Beyond jump-starting, the GP4000 functions as a high-capacity power bank, which is especially useful during road trips, camping, or power outages. With both USB-C and USB-A fast-charging ports, you can quickly charge your smartphone, tablet, GPS, or even laptop on the go.

How the GOOLOO GP4000 Compares to Other Jump Starters
When it comes to heavy-duty jump starters, the GOOLOO GP4000 stands out with its 4000A peak current and 26800mAh battery capacity—features that place it firmly in the top tier of portable power units. However, it’s important to see how it stacks up against other popular models to better understand its value.
Compared to the NOCO GB150, which also offers high power but at a much higher price, the GP4000 provides a more budget-friendly alternative without sacrificing essential performance. While the NOCO boasts brand recognition and premium build quality, the GOOLOO delivers comparable power and added features like USB-C PD charging at a more accessible cost.
On the other hand, if you’re considering something like the AVAPOW A68, you’ll notice those models offer lower peak amps and may not handle larger diesel engines as confidently. The GP4000, in contrast, is built specifically for larger vehicles and more demanding jump-starting situations.
In short, if you’re looking for a jump starter that can handle big engines, offer fast device charging, and survive harsh environments, the GOOLOO GP4000 holds its own—and even outperforms many competitors—in the same price range.
Other GOOLOO Jump Starter Models
GOOLOO has built a solid reputation as one of the most trusted names in the jump starter industry, offering a wide range of products that combine high power output, advanced safety features, and user-friendly design. Whether you’re looking for a compact device for everyday emergencies or a heavy-duty model for large engines, GOOLOO has an option to match your needs.
