[0023] By analyzing the prior art, the inventors found that the voltage of existing lithium batteries is generally 3.7V, and the voltage that can be provided by lithium batteries can only be an integer multiple of 3.7. This results in some electrical devices with standard voltages of 5V, 7V or 9V being unable to directly use lithium batteries to work, and requiring an external boost module, which increases the use space of the equipment and requires additional assembly, making the overall equipment more complicated to use.
