Why does the UVP warning appear on the Anker 737 PoweBank’s screen when charging a laptop？
If the USB C port of the laptop is a PD port, which can support two-way charging, it means it can either accept power or supply power via this port. While the USB C1 port in our power bank is also a two-way charging port. Therefore, when connecting the laptop to the power bank’s USB C1 port, both of them may get confused. If the powerbank wrongly recognizes the connected laptop as a power input source, then the UVP warning may appear.
The USB C2 port will not cause such a problem since it is only a power output port, please give it a try.
