[0025] See also Figure 1 and Figure 2 As shown, a battery charging slot 6 is provided within a rectangular housing 1. A negative contact 61 and an adjustable positive contact 62 are provided at each end of the battery charging slot 6. The position of the adjustable positive contact 62 within the battery charging slot 6 is adjustable, so that the spacing between the negative contact 61 and the adjustable positive contact 62 is suitable for installing AA batteries and AA batteries. The positive and negative output terminals of the energy storage module 5 are electrically connected to the adjustable positive contact 62 and the negative contact 61, respectively. Specifically, the rectangular housing 1 is divided into a battery chamber and a device chamber by a vertical partition 11, and the device chamber is divided into a power generation chamber and an energy storage chamber by a horizontal partition 12.
