The end of our energy storage power supply is a 5.5×2.1mm charging port, and the other end of the solar panel connection cable also requires 5521 to be used. For example, if your solar panel interface is MC4, you need a 5521 to MC4 adapter cable to use our energy storage power supply for charging. It is recommended to use a solar panel with a maximum charging capacity of 120W (7A current).
