Mobile power source
A mobile power source includes a housing, a connecting plate, a battery assembly, and a circuit board. The housing includes a hollow middle housing having openings at an upper end and a lower end thereof, and an upper cover and a lower cover latched to the openings at the upper end and the lower end, respectively. The middle housing is provided with a plurality of pillars spaced along a vertical direction at an inner side wall thereof. The connecting plate abuts against the support surface and is fixed to the plurality of pillars. The battery assembly is disposed in the housing, which includes a battery pack, and an upper support member and a lower support member disposed at an upper end and a lower end of the battery pack, respectively. The circuit board is disposed on the upper support member.
