Andrii my device is full charged and input and output cables connect to my device. In this case device doesn’t allow to use AC and doesn't work as a UPS. Why?
Zendure I'm sorry, your device is SBP1500? Your situation is, in UPS function, when the battery power is 100%, the AC is automatically switched off?
Zendure For the problem, SBP1500, AC automatically turns itself off when fully charged. Could you provide the SN number so that we can check here. I am looking forward to your reply.
support Please don't worry, firmware update is ready, you could just do through app update. Please try. Have a nice day.
support Could you provide the SN number and IMEI so that we can here update for you. I am looking forward to your reply. Have a nice day.
