X703
,A:No, the X703 UPS does not support rpi poe hat.
Q2: Why CHG light is not light up when external power supply is connected?
# The X703 UPS does not discharge when charging. Therefore, when external power adapter is used, raspberry pi is powered by the power adapter instead of UPS.
# When remove the external power adapter, raspberry pi will be powered by the battery, which can avoid frequent battery charging and discharging.
# Please make sure that the power adapter used is ≥3A, and always short the CHG , so that it can be automatically charged when an external power supply is connected.
