With a peak current of 4000A, it can start almost all 12V vehicles, including gasoline engines up to 12.0L and diesel engines up to 10.0L. The GT4000S also works as a 100W power bank, letting you charge your phone, tablet, or laptop while traveling.

A portable jump starter that doubles as a power bank and flashlight
When you’re not using the GT4000S as a jump starter, it’s a compact unit that stores in your trunk. Combining a 4000A jump starter, a 100W two-way USB-C rapid charger, a 400-lumen LED light, and ten layers of safety protection, it’s ready to help with a dead battery or a long night parked on the side of the road.
With GOOLOO’s JUMPCORE technology, the GT4000S delivers a peak current of 4000A, enough for most vehicles, including cars, SUVs, trucks, RVs, and boats. One fully charged unit can support up to 60 jump starts, and BOOST mode can help revive very low batteries.
Operating the jump starter is easy. Attach the clamp leads to your vehicle’s battery terminals, then start your engine. Ten protective features of GOOLOO’s SuperSafe system guard against electrical sparks, reverse polarity, excessive current flow, and short circuits, helping prevent damage if you attach the clamps incorrectly.
The GT4000S can quickly recharge. When connected to a compatible charger via its USB-C port, which supports 100W Power Delivery input, the jump pack charges from completely empty to full in about 1.2 hours, and just five minutes of charging provides enough energy for an emergency jump start.
That same USB-C port also provides 100W output, so you can charge a MacBook or other USB-C laptop at full speed. You also get two additional USB-A ports and a 15V/10A DC port, enabling you to power your phone, tablets, tire inflators, and other gear while stranded.
While you’re waiting for assistance or searching for alternative routes, these ports can be useful. For example, you can charge your phone while you search for help online, or inflate your tires before returning home with a tire inflator attached to the DC port.
Along with its functions as a portable jump starter and power bank, the unit includes a built-in 400-lumen LED flashlight with three modes, Spotlight, Strobe, and SOS, providing you with visibility under the hood of your vehicle when working late at night or signaling for help should you require it. The GT4000S retains its charge for up to 24 months on standby, reducing the need to recharge it often, and its display shows the unit’s stored power at a glance.
The GOOLOO GT4000S 12V 4000A Peak Jump Starter contains 20,000mAh of capacity in a design that’s compact enough to store in a glove compartment or under a seat. It’s an intelligent accessory for any vehicle and also offers an auxiliary portable power supply that travels with you.
