It is more convenient for outdoor travel. This kind of rechargeable electronic product has undoubtedly greatly improved people's freedom of life, but it will inevitably bring corresponding troubles. Once the power in the electronic product is exhausted, and we are in an environment where it is difficult to find an AC power source , such as outdoors, you can only look at these dazzling electronic products and sigh. In order to solve this trouble, the prior art provides such a mobile power supply, which includes a plug, a main body of the mobile power supply with a storage battery and a connector, so that we can fully charge the mobile power supply before we go out. When the power of the device is exhausted, the mobile power supply can be used to charge it to solve the problem of not being able to find the AC power supply.

Although this mobile power supply of the prior art can solve the temporary needs, the disadvantages are also obvious. If people forget to fully charge the mobile power supply when they go out, or although it is full, it is still not enough to meet the electricity needs of electronic equipment. The problem of finding a power source is still unresolved.

Utility model content

The technical problem to be solved by the utility model is to provide a mobile power supply, which can not only carry out mobile charging when needed, but also solve the problem in the prior art that the power reserve of the mobile power supply is exhausted and still needs to find an external power supply.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A mobile power supply is provided, which includes a casing and an energy storage device, the casing is provided with a power output interface, the energy storage device is arranged in the casing, and is electrically connected to the power output interface, and the energy storage device can Replacement generic battery.

After adopting such a structure, the energy storage device of this product is a general-purpose battery that can be replaced. In this way, when the user goes out, he only needs to carry or purchase a sufficient amount of batteries to meet the needs of electronic equipment. The universal battery can be purchased anywhere, so it cleverly solves the inconveniences caused by the use of accumulators in the prior art.

Fig. 2 is a schematic diagram of the assembled structure of Fig. 1;

FIG. 3 is an exploded schematic diagram of the structure in FIG. 1 .

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

A preferred embodiment as shown in Figures 1-3, it includes a housing 1 and an energy storage device 2, the housing 1 is provided with a power output interface 11, the energy storage device is arranged in the housing 1, and is connected with The power output interface 11 is electrically connected, and the energy storage device is a replaceable universal battery (not shown in the figure). After adopting such a structure, the energy storage device of this product is a replaceable general-purpose battery, so that when the user goes out, he only needs to carry or purchase a sufficient amount of batteries to meet the electricity demand of electronic equipment. Universal batteries can be purchased anywhere, and batteries of different capacities, brands, qualities, and prices can be selected and installed and replaced by themselves, thus ingeniously solving many inconveniences caused by the use of accumulators in the prior art.

In order to further enhance the convenience of the utility model, as a better embodiment, a power input interface 12 can be added on the housing 1, and correspondingly, the universal battery can use a rechargeable battery (in the figure not shown), the rechargeable battery is electrically connected to the power input interface 12. In this way, when a large amount of electricity is not required, in order to achieve the purpose of environmental protection and cost saving, a rechargeable battery can be used. When there is an AC power supply, the rechargeable battery can be charged through the power input interface 12. When the electronic device is out of power, the charged battery can be used to supply power to the electronic device through the power output interface 11 . Of course, this does not mean that it is not possible to switch to a general-purpose dry battery when the power of the rechargeable battery is exhausted under special circumstances. During specific implementation, the rechargeable battery is preferably a 18650 standard lithium ion battery (not shown in the figure), which is a lithium battery commonly used in electronic products, and is often used as a battery cell in a notebook computer battery , Like this, the utility model can also be used as the mobile power source of this lithium-ion battery at ordinary times.
