support I've checked for you, but I don't think DC is the latest version yet, so please try updating it first. Is the AC charging power set in the app? Reset the device or reboot and see if it works. Have a nice day.
Word The logic of Zendure is asinine. Why have two firmwares for two separate power standards if the performance of one lower standard is dependent on the firmware of both standards? This is simply poor planning/coding. It feels like everyone is beta testing these units. Zendure needs to get their shit together.
support Yes, in theory it is unaffected. Just a suggestion, you can bring the DC firmware up to date and give it a try. Does the AC charge normally if sleep mode is turned off?
