• USB-A Port: Up to 20W max output for smartphones and other smaller devices.

Multi-Port Charging:

The power bank features smart power distribution. When multiple devices are connected, the total output of 140W is dynamically allocated. For example:

• Two USB-C Devices: Up to 100W from one USB-C port and 65W from another.
• Three Devices (2x USB-C, 1x USB-A): Up to 60W from each USB-C port and 20W from the USB-A port.

6.2 Recharging the Power Bank

Connect a 140W PD3.1 compatible charger to the USB-C1 input port. The power bank can be fully recharged in approximately 1.5 hours. The smart bi-directional power distribution allows the power bank to autonomously recharge itself when connected as a desktop charging station and the output demand is lower than the input power.

6.3 Desktop Charging Station Mode

When the power bank is connected to a wall outlet via its USB-C1 input, it functions as a desktop charging station. It can simultaneously charge connected devices and recharge its internal battery.
