Attention! The jump starter is designed exclusively for starting a car when the battery is discharged; it is not intended for charging the battery.

3-MINUTE ULTRA-FAST CHARGING TO 20% READY FOR USE

3.2-INCH INFORMATIVE LED SCREEN SHOWS ALL STATUS AT A GLANCE

The 3.2-inch LED screen shows battery level, specific operating status, and error reminders. View all information with ease.

PORTABLE CHARGER FOR MULTIPLE DEVICES

With 2 USB ports and 1 Type-C port (max input/output power 100W), it can also function as a portable 26800mAh power bank to charge all your devices, such as your phone, iPad, and even Macbook.

Press and hold the POWER and BOOST buttons simultaneously for 2-3 seconds to enable low current mode for charging devices that require a small charging current, such as headphones, smartwatches, etc.

Note: Based on internal testing: Performance depends on chargers and charging cables. To achieve 100W, the charger must support PD 100 Max input. Most phones, such as Samsung and Huawei, have their own protocol that does not allow 100W to be achieved when using the GT4000S. For best results, please use the included USB C to USB C cable.
