The GOOLOO GT4000S can start your car at temperatures ranging from -20°C to 60°C. You don't need to worry, even when winter is coming.

The GT4000S jump starter will make a great gift for your family or friends. It will be helpful in their driving life.

This portable lithium car battery jump starter pack has a 3.2-inch informative LED screen that clearly shows the product's status, so you can intuitively know when to start the car. It also has built-in 10 types of protection technology to free your mind of any concerns about misoperation and sparks.

Only 1.2 hours are required to fully charge the jump box from 0% to 100%. Just 5 minutes of charging time are enough to start a car (a 100W car charger is included in the package). A single full charge can achieve 60 jump-starts. You can also use your own fast-charging charger to charge this jump starter through the Type-C port.

The GT4000S can charge laptops as fast as their original adapters (Type-C port only), allowing you to charge it whenever and wherever you need.

With a peak cranking power of 4000A, the Gooloo GT4000S can start almost all 12-volt dead vehicle engines up to 12.0L gasoline or 10.0L diesel in just a few seconds. Compared to a traditional car jumper or jumper cables kit, it is powerful enough but more compact. It is perfectly compatible with RVs, pickup trucks, motorcycles, SUVs, tractors, boats, and more.

Regular charging is not necessary as long as you own the GT4000S battery jump starter, as the built-in 10 protection technologies greatly extend the product's service life.

The GOOLOO GT4000S is not just a jump starter battery pack; it also features a portable battery bank with three USB ports and a 400-lumen flashlight with three modes (SOS, Spotlight, Strobe). It also has a 15-volt, 10-amp port for powering any 15V or 12V DC devices, like tire inflators, inverters, and more.

In the box, you will find the Gooloo 4000A Portable Car jump starter battery pack GT4000S, Heavy Duty Jumper Cables, SC 100W Car Charger, USB to Type-C Cable, Type-C to Type-C Cable, Cigarette Lighter Adapter, Storage Bag, and User Manual.
