Question about EZVIZ 12W battery solar panel

I was able to do some research and supposedly according to the manufacturer this solar panel is compatible with all EZVIZ battery powered cameras. It has USB outputs, so it charges with the USB standards. The H90 (manufacturer number CS-H90-R100-8H44WKFL) is not a camera with an integrated battery and is charged via 12V, so it is not compatible with a solar panel. Solar panels are more recommended for a camera with an integrated battery, as solar energy is not always available and the camera still needs to be supplied with power.
