I have just bought the power bank. However, I have a problem with charging. Passthrogh works, but as soon as I try to charge the powerbank on its own, it displays an error message (four flashing lights). The powerbank is within the recommended temperature range. I am using the Ugreen Nexode Pro 65 W charger. The error message occurs with both the strong and weak sockets. What is the reason for this? Actually, all common fast charging technologies are supported according to the manufacturer's specifications.
