Abstract: A retractable charging apparatus includes a retraction roller mechanism, a charging mechanism and a main PCB. The retraction roller mechanism includes a first driving apparatus, a transmission component having a power connection to the first driving apparatus, and at least one level of roller components connected to the transmission component. Each level of roller components includes two rollers disposed opposite each other. The first driving apparatus is electrically connected to the main PCB. The charging mechanism includes a charging PCB connected to the main PCB. The main PCB controls the first driving apparatus to drive the retraction roller mechanism. In use, a user places a power supply between the two rollers. The rollers retract the power supply into the charging apparatus, and convey the power supply to a charging mechanism for charging. After charging is completed, a retraction roller mechanism conveys the power supply out.

Abstract: A leasing terminal of a mobile power supply comprises a CPU, a network communication module and a main control MCU which are respectively connected to the CPU, and at least one charging module, at least one charging cabinet motion drive motor and at least one mobile power supply information reading module which are respectively connected to the main control MCU; and each charging cabinet corresponds to one charging module, one charging cabinet motion drive motor and one mobile power supply information reading module. By means of the present invention, when a user is outside, a mobile power supply can be leased from a leasing terminal of the mobile power supply in a self-service manner, thereby providing the flexible charging service to the user.

Abstract: A mobile power source includes an upper cover, a charging battery, a circuit board, a group of charging input metal contacts and a lower cover. The upper cover and lower cover match to form a mobile power source case, and the charging battery and group of charging input metal contacts are respectively electrically connected to the circuit board. The charging battery and circuit board are accommodated in the mobile power source case, and the group of charging input metal contacts are exposed outside of the mobile power source case.
