Each of the supporting stands 300 has a supporting container 310 which have different standards with each other. Each of the supporting stands 300 has a slot 320 disposed on a bottom of the supporting container 310 as well as corresponding to the supporting container 310.
The charging circuit 200 is disposed in the base 100. The charging circuit 200 has a first electrical connector 210. The first electrical connector 210 protrudes from the coupling surface 111. When the coupling portion 110 is coupled with the supporting stand 300, the first electrical connector 210 penetrates through the slot 320 such that a portion of the first electrical connector 210 is disposed in the supporting container 310. Therefore, a user can place an electronic product matching the standards of the supporting container 310 on the supporting stand 300 for charging the electronic product.
Furthermore, if the electrical connectors of various electronic products are of the same type and only the shapes of the various electronic products are different, the user only have to substitute another supporting stands 300 which matches the shape of the certain electronic product, and therefore the electronic products with different standards can be charged through the same charger 10. The way of using the charger 10 will be described later.
In this embodiment, the coupling portion 110 comprises two fastening pieces 120. The two fastening pieces 120 are disposed on two opposite sides of the coupling surface 111, respectively. The supporting stand 300 comprises two fastening indentations 330 disposed on two opposite sides of the supporting stand 300, respectively. The two fastening pieces 120 may be detachably fastened with the two fastening indentations 330 correspondingly such that the supporting stand 300 may be detachably fastened on the base 100. Thus, the user can substitute the supporting stand 300 rapidly with the above-mentioned fastening mechanism between the fastening pieces 120 and the fastening indentations 330.
In this embodiment and other embodiments, the base 100 further comprises a coupling indentation 130 and an upper surface 140. The upper surface 140 is connected with the circumference of the coupling indentation 130. The coupling indentation 130 is used for being coupled with one of multiple battery boxes 400. Moreover, the charging circuit 200 further comprises a second electrical connector 220 disposed in the coupling indentation 130. The battery boxes 400 may be detachably installed in the coupling indentation 130. Each of the battery boxes 400 has an accommodating indentation 410 and a third electrical connector 440. The accommodating indentation 410 is used for accommodating at least one battery 30. The third electrical connector 440 is disposed in the accommodating indentation 410 for electrically connecting with the battery 30. Furthermore, the third electrical connector 440 is partially exposed outside the accommodating indentation 410. Therefore, when the battery box 400 is detachably installed in the coupling indentation 130, the third electrical connector 440 may be detachably and electrically connected with the second electrical connector 220.
The following describes the fastening structure between the base 100 and the battery box 400. Each of the battery boxes 400 comprises a first fitting portion 420 and a second fitting portion 430. The first fitting portion 420 and the second fitting portion 430 are disposed on two opposite sides of the battery box 400, respectively. The base 100 comprises a third fitting portion 150 and a fourth fitting portion 160.

When the battery box 400 is installed in the coupling indentation 130, the first fitting portion 420 is fastened with the third fitting portion 150, and the second fitting portion 430 is fastened with the fourth fitting portion 160.
In some embodiments, the first fitting portion 420 is a convex-shaped block, and the third fitting portion 150 is a concave indentation whose shape matches with that of the convex-shaped block. The second fitting portion 430 comprises an elastic piece 431 and a convex-shaped block 432. The elastic piece 431 has a fastening section 431a and a releasing section 431b. The fastening section 431a and the releasing section 431b are connected with each other. The fastening section 431 a is connected with the battery box 400, and the fastening section 431a is positioned between the battery box 400 and the base 100. The convex-shaped block 432 is disposed on a surface of the fastening section 431a facing the coupling indentation 130. A portion of the releasing section 431b protrudes from the upper surface 140. The fourth fitting portion 160 is a concave indentation corresponding to the convex-shaped block 432. The convex-shaped block 432 faces the fourth fitting portion 160, and the convex-shaped block 432 is normally fastened with the fourth fitting portion 160 by the elastic piece 431. The user can press the releasing section 431b to make the convex-shaped block 432 move relatively further away from the fourth fitting portion 160 in order to detach the battery box 400 from the coupling indentation 130. Therefore, the battery box 400 with other standards may be substituted later.
