Mobile power source

A mobile power source, comprising:

• a housing, the housing comprising 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, wherein the middle housing is provided with an input interface and a plurality of output interfaces, the middle housing is provided with a plurality of pillars spaced along a vertical direction at an inner side wall thereof, upper ends of the plurality of pillars are spaced from the upper end of the middle housing, lower ends of the plurality of pillars are spaced from the lower end of the middle housing, the upper ends of the plurality of pillars cooperatively form a support surface, the lower ends of the plurality of pillars cooperatively form a limiting surface;
• a connecting plate abutting against the support surface and fixed to the plurality of pillars, the upper cover being detachably connected to the connecting plate;
• a battery assembly disposed in the housing, the battery assembly comprising 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, wherein the upper support member is fixed to the connecting plate via a first connecting member, the lower support member extends along a horizontal direction to form a mounting edge having a size profile adapted to the middle housing, the mounting edge abuts against the limiting surface and is fixed to the pillar via a second connecting member, the lower cover is connected to the lower support member;
• and
• a circuit board disposed on the upper support member, the battery pack, the input interface, and the output interface are electrically coupled to the circuit board, respectively.
