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.
X703
,==Note==
* NOT supports software safe shutdown.
* Do not apply power <span class="tb_red">Please use the type-c of the X703 to your charge instead of the Raspberry Pi 4 via the Type-C socket.</span>
* Please use high quality power supply, the low quality power supply will generate surge Voltage, which will damage the board chip. we recommend Panasonic brand NCR18650BD 18650 lithium battery.
* If 【CHG】 pin is OPEN, battery charging will be started after powering on (short press the on-board button to turn on) and stopped after powering off(press and hold for 2-3 seconds to turn off). If 【CHG】 pin is SHORT, the battery will be automatically charged once your power adapter connected.* Do not short The purpose of adding the 【CHG】 jumper is to extend the life cycle of the battery by reducing the"AON" pinnumber of recharges.
* Be sure to power off & remove the 18650 battery then wait for 2 seconds when toggle charging mode
A:No, the X703 UPS does not support rpi poe hat.
