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 24000 mAh 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 activate low-current mode for charging devices that require a small charging current, such as headphones, smartwatches, etc.

Note: According to our own 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 when using the GT4000. For best results, please use the included USB C - USB C cable.
