Can you disable auto-boot if you plug power in? In some situation you do not want to boot only charge.

Hardware or software modification needed?

What happens, if I connect a USB C power supply that does not provide 5V 5A but for example 5V 3A.

Will the UPS use the batteries to make up for the missing power? Is it possible to charge the UPS with 5V 3A when the PI is turned off?

Thank you

Hi,When the load is heavy and the USB-C power supply is insufficient, the UPS will draw power from the battery. But if the USB-C power supply does not have overcurrent protection, it may be damaged. It is recommended to use 5V 5A power supply.

Manual says "Note: the voltage range must be 3.00~4.10vdc." 18650's can go down to 2.5V per cell. Can the minimum be 2.5-2.7V or is 3.0V min a hardware limitation?

After using the USB C port on the x1202 I heard the board making small ticking noises. After I pulled the plug the entire unit lost power. Is the USB C port not the preferred port?
