Precautions

If the total output exceeds 300W, the AC output is given priority, so the USB- port will switch to 5V charging speed. The USB-C port fast charge will function properly only when the total output is less than 230W.

Pass-through charging

Pass-through charging is supported by 3 USB-A ports only. You can use the USB-A ports while simultaneously recharging the power station using either of the four charging options. USB-C, DC and AC ports do not support pass-through charging.
