Output Operation

3.2.1 USB Output

External AC power mode: all 3 ports (USB-A-QC3.0, Type-C-PD-18W, and

USB-A-5V1A) are active, and they can charge mobile phones, tablets,

digital cameras and other electronics devices. However, when USB-A-

QC3.0 and Type-C-PD-18W are used simultaneously, only 5V3A charging

is supported, and the combined output power of the two interfaces is

15W. 23W is the max output of USB ports when USB-A-5V1A is used and

one of these 2 ports (USB-A-QC3.0, Type-C-PD-18W) is used.

Internal battery power mode: when the “OK” key is pressed, among the

3 USB ports, only the USB-A-5V1A port is active, and the other two ports

are not active.

3.2.2 AC Output

The AC output is active only in external AC power mode. Other than

the ON/OFF switch, an overcurrent fuse at the three-in-one socket

provides extra safety. The fuse allows a current of up to 10A, so that the

combined load current connected to the AC expansion ports should be

controlled within 10A. As shown in the figure below, the middle of the

three-in-one socket is a fuse. When the fuse compartment is pulled out,

it can be seen that there is a spare fuse inside. When the working fuse is

burned out, the spare one can be used as a replacement.
