Abstract: A mobile power bank includes at least two cuboid modules including a control module and a battery module. The battery module includes a first telescopic element disposed on a first side, a first hole corresponding to the first telescopic element, a second telescopic element disposed on a sixth side, and second holes. The control module includes a first telescopic element disposed on a first side, a first hole corresponding to the first telescopic element and disposed on a second side, a power function element disposed on a sixth side, and second holes. The first telescopic element is electrically connected to the first hole in a pluggable manner. The second telescopic element is electrically connected to the second hole in a pluggable manner. The control module manages charging and discharging of the battery module accessed to the control module.

Abstract: A mobile power supply may include a charging and discharging interface, a charging and discharging circuit, a central processor, and a battery pack. The charging and discharging circuit may be configured to adjust a voltage inputted to the battery pack to charge the battery pack when the voltage inputted to the battery pack is not matched with a voltage of the battery pack, or configured to adjust a voltage output to the electronic device to charge the electronic device when the voltage outputted to the electronic device is not matched with a rated voltage of the electronic device. The central processor may be configured to control the charging and discharging circuit to charge the battery pack, supply power to or charge the electronic device.
