[0001] An object of the present invention is to provide a mobile battery pack with multiple discharge functions and high adaptability.

[0002] In order to achieve the above object, the technical solution adopted by the present invention is specifically as follows: a multi-functional battery pack includes a battery pack body, and a plug interface discharge group and a cable discharge group are provided on the battery pack body; the plug interface discharge group includes a USB interface and a Type-C interface; the cable discharge group includes a first cable and a second cable, and the first cable and the second cable have different types of connector portions, such as a Lightning interface type connector portion and a Type-C interface type connector portion respectively. In addition, the plug interface discharge group may also be provided with other types of plug interfaces, and the cable discharge group may also be provided with cables with other types of interfaces.

[0003] In some other embodiments, the present invention also provides a multi-functional battery pack including a battery pack body, a plug interface discharge group and a cable discharge group; two accommodating grooves are provided on the battery pack body for accommodating a connector portion of a first cable and a connector portion of a second cable; one end of each of the accommodating grooves is provided with a wire groove for accommodating a wire portion of the first cable or a wire portion of the second cable; the plug interface discharge group includes a USB interface and a Type-C port; and the cable discharge group includes the first cable and the second cable, and the connector portion of the first cable is a Lightning connector, and the connector portion of the second cable is a Type-C connector. Here, the plug interface discharge group and the cable discharge group are disposed on the battery pack body; and state display lights are provided on both sides of the battery pack body for displaying power level and working state of the battery pack. Furthermore, a groove width of the wire grooves is smaller than a groove width of the accommodation grooves, the two accommodating grooves are respectively provided with an arc-shaped wall at the other ends away from the wire grooves, and the connector portion of the first cable and the connector portion of the second cable are both disposed below the arc-shaped walls.

[0004] Compared with the prior art, the present invention has the following beneficial effects:

[0005] 1. The battery pack of the present invention integrates plug interface discharge and cable discharge functions, providing Auser with multiple discharge methods. If the connector portion of the cable is not compatible, other external cables may be connected for use, thereby improving versatility and adaptability of the battery pack.

[0006] 2. When the first cable (e.g., a Lightning cable) or the second cable (a Type-C cable) is used, the connector portion of the cable can be held down with a finger and pushed toward the arc-shaped wall of the accommodating groove to allow the connector portion to move forward and move up along the arc-shaped wall of the accommodating groove; and at the same time, the wire portion of the cable further moves into the wire groove, and when the connector portion of the cable moves up along the arc-shape wall to protrude from the accommodating groove, the connector portion of the corresponding cable can be taken out, and then the cable can be pulled out.

[0007] 3. Combining the functionality and adaptability of new energy electric tool battery packs with mobile battery packs further increases applicability of the product.
