CCC certification is a compulsory product certification in China and is not an optional item. First of all, compliance is the foundation of market access. Cylindrical batteries that have not been certified cannot be sold in the domestic market and cannot be used in the production and circulation of complete machine products. Secondly, certification can prove that the product complies with national safety standards, reduce risks such as fire and electric leakage during use, and enhance consumer trust. Finally, products with CCC certification are more competitive in bidding and channel cooperation, serving as a \"pass\" for enterprises to expand their markets.

Smart bracelets have long become a \"little helper\" for daily health management, and the built-in battery, as the core power source, directly affects the battery life and usage safety of the bracelet. Most of these batteries are lithium-ion batteries, which have high energy density and small size, making them suitable for the portability of smart bracelets. However, due to their chemical properties, they need to meet specific safety standards during transportation and use. The un38.3 certification is precisely the core safety certification for this type of lithium battery.

As a commonly used portable charging device, power banks cannot do without UN38.3 certification whenever they are involved in air transportation, entering regular markets or doing cross-border business.
