The first national standard for mobile power supplies (power banks) in China, GB/T 35590-2017, "General Specification for Mobile Power Supplies for Portable Digital Devices in Information Technology," was implemented on July 1, 2018. This standard includes: scope of application, normative references, terms and definitions, requirements, testing methods, quality assessment procedures, marking, packaging, transportation, and storage. The national standard for mobile power supplies specifies the requirements, test methods, quality evaluation procedures, marking, packaging, transportation, and storage of mobile power supplies for portable digital devices (hereinafter referred to as "mobile power supplies"). The specification is applicable to mobile power supplies with input voltage not exceeding 250V, output DC voltage not exceeding 60V, single port output current not exceeding 5A, and wired output mode used for portable digital devices. Secondly, specific and clear requirements should be made for various aspects of mobile power supply, including appearance identification, performance, safety protection, safety, electromagnetic compatibility, environmental adaptability, and the limit of restricted substances. For example, the cycle life of mobile power supply should not be less than 300 times, and the product must have overvoltage protection, overvoltage protection, short circuit protection, overload protection, and misoperation protection
