A junction box 20 is fixedly connected to the bottom of the base 3. The input end of the junction box 20 and the output end of the power bank body 2 are electrically connected via second wires 21. The positive terminal of the output end of the junction box 20 is electrically connected to the bottom end of the first copper conductive post 6, and the negative terminal of the output end of the junction box 20 is electrically connected to the bottom of the first copper plate 8. This allows the power bank body 2 to charge the mobile phone body 30. The surface of the first rubber shell 1... A carrying strap 31 is fixedly connected to the side for easy carrying. The clamping assembly includes multiple square slots 22, each of which is opened into the inner wall of the phone placement slot 28. A slider 24 is slidably embedded inside each of the square slots 22. A second spring 23 is fixedly connected between each of the square slots 22 and the sliders 24.
