From the design of designer Gan Yexin et al., the scroll-type E-Saving Battery achieves a perfect balance between the area of ​​solar cells (power generation efficiency) and portability:
It still doesn't look much different from the usual mobile power supply. The columnar shape is output through the USB port - but it has a built-in flexible solar cell. When needed, the solar cell can be made by holding the lever on the back. Pull out like a reel to get the maximum light area and improve power generation efficiency. In normal times, when the panel is closed, it does not take up any space.
