Abstract
The invention relates to a freely capacity-increasing mobile power supply comprising a main body and an auxiliary body. Battery cases are arranged in both the main body and the auxiliary body. The both ends of each battery case are fixed with wafers. The main body and the auxiliary body are in electrical connection through the wafers. The sidewall, connected to the auxiliary body, of the main body is fixed with first magnets. The sidewall, connected to the main body, of the auxiliary body is fixed with second magnets attracted to the first magnets. The sidewall, far away from the main body, of the auxiliary body is fixed with first magnets. The beneficial effects of the present invention are that since the batteries in the main body and the auxiliary body are in parallel connection, accordingly, the quantity of the auxiliary body can be increased without limitation. Consequently, the capacity of the battery in the main body can be set to be relatively small. The weight of the power supply is reduced. When the electric quantity in the battery in the main body is exhausted, the main body can be connected to one or more auxiliary bodies selectively according to actual conditions. The auxiliary bodies which are not used do not need to be carried. Thus, the freely capacity-increasing mobile power supply has the advantages of convenient operation and portability.
