Abstract: The present disclosure discloses a drive circuit of an energy storage power supply and an energy storage power supply. The drive circuit of an energy storage power supply includes a charging control circuit, a first direct current output circuit, an alternating current output circuit and a main control circuit. The main control circuit can detect the load condition of the first direct current output circuit and the alternating current output circuit, and then the main control circuit controls the first direct current output circuit and the alternating current output circuit to be off. Thus, the problem of high power consumption when the alternating current output circuit and the first direct current output circuit in the energy storage power supply are in the no-load state is solved.

Abstract: The utility model discloses a hand warmer with detachable battery, which relates to the hand warmer field, and comprises a shell, wherein the outer side of the shell is provided with a hardware piece, the inner side of the shell is fixedly provided with a PCB motherboard, and the inner side of the shell is also provided with a detachable battery compartment; the bottom of the shell is provided with an opening structure, and a battery cover is clamped at the opening, and the battery cover can be detached from the opening; the outer side of the shell is also provided with silica gel, which is formed by splicing two plastic shells, and the silica gel is arranged outside the connecting seam of the shell. By arranging the battery cover, which can be directly detached from the shell, the utility model is convenient to replace the battery, and can be used for hand warmers all day.
