Description

Technical Field

[0001] This utility model belongs to the technical field of electronic device accessories, specifically relating to a battery charging box. Background Technology

[0002] In the field of sports photography equipment, action cameras are widely used in extreme sports, outdoor adventures, and other scenarios due to their portability and high impact resistance. In the field of action camera technology, the battery charging case, as an important accessory, is mainly used to provide battery life support for the device. Currently, most action camera charging cases on the market adopt traditional contact-type or single USB interface designs, limiting their functionality to basic charging scenarios and failing to meet the increasingly diverse needs of users. The main technical shortcomings are as follows: Limited interface functionality: Existing charging case physical interfaces (such as Micro-USB, Type-C, or magnetic contacts) only support unidirectional power transmission. Users need to carry an additional data cable or dedicated adapter to charge. Furthermore, the user experience of the charging case is relatively limited. Utility Model Content
