[0074] The charging compartment 20 includes a compartment body 21 and a compartment cover 22 connected to each other, forming a product receiving cavity for accommodating products. The charging compartment 20 also includes a first battery 24, a first power receiving device 23, and a second power output device 25. The first power receiving device 23 is electrically connected to the second power output device 25 via the first battery 24. The first power receiving device 23 receives electrical energy output from the first power output device 24 and charges the first battery 24. The charging box 10 charges the first battery 24, the first battery 24 supplies power to the second power output device 25, and the second power output device 25 charges the product inside the product receiving cavity.

[0075] An embodiment of the second aspect of this application also provides an electronic device 1000, please refer to... Figures 1 to 5 The electronic device 1000 includes a wearable device 200 and a charging device 100 according to any one of the first aspect embodiments, a product receiving cavity for receiving the wearable device 200, and a charging compartment 20 for charging the wearable device 200 in the product receiving cavity.

[0076] The wearable device 200 includes multiple rechargeable products or components. Multiple charging cases 20 have multiple product-receiving cavities for accommodating the rechargeable products or components within the wearable device 200. The multiple charging cases 20 are used to charge the multiple rechargeable products or components within the wearable device 200 respectively. Optionally, the wearable device 200 can be headphones, smart glasses, or a complete device including headphones and a wristband. For example, when the wearable device 200 is headphones, there are two charging cases 20, one for charging the left earbud and the other for charging the right earbud. For example, when the wearable device 200 is smart glasses, there are two charging cases 20, one for charging the left temple and the other for charging the right temple.

[0077] The beneficial effects of the embodiments of this application are as follows: the electronic device 1000 includes the charging device 100 in the first aspect embodiment, and the user can carry only some of the products that need to be used and the charging case 20, so the user's burden is small; the electronic device 1000 has all the effects of the charging device 100.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
