In today's society that highly relies on portable electronic devices, portable energy storage power sources (mobile or outdoor power sources) have become an indispensable companion for people's travel and daily life. However, in order to ensure the safety and performance consistency of these portable energy storage power supplies, they need to undergo a series of strict certifications.

The certification of portable energy storage power mainly includes national certification, safety certification, battery certification, EMC certification, and environmental certification. These certifications are not only the responsibility of manufacturers, but also an important part of safeguarding user rights and security.

Firstly, it is recognized by the national government. Different countries or regions may have their own certification bodies, such as China Quality Certification Center (CQC) or China General Administration for Quality Supervision, Inspection and Quarantine (CIQ). Through national recognition, portable energy storage power supplies can enter the market and prove that they comply with relevant domestic regulations and safety standards.

Next is security certification. The safety of mobile power supplies is very important as they involve components such as batteries, charging circuits, and cooling systems. Obtaining international or regional safety certifications, such as CE certification in Europe and UL certification in the United States, can ensure that products do not pose a threat to personal safety during normal use.

Battery certification is another factor that cannot be ignored. Batteries are the core components of portable energy storage power supplies and must meet specific battery quality and safety standards. For example, UN38.3 certification and IEC62133 certification require that batteries will not experience unsafe situations such as short circuits, overheating, or explosions during transportation and use, in order to protect the safety of users.

Electromagnetic compatibility (EMC) certification is also essential. Portable energy storage power supplies can generate electromagnetic radiation during operation, which may cause interference to other electronic devices or be susceptible to interference from other devices. EMC certification such as CE certification in Europe and FCC certification in the United States can ensure that products meet the requirements of Electromagnetic compatibility when used, and reduce the impact of electromagnetic interference on other equipment and human body.

Environmental certification. In today's world where sustainable development and environmental protection are increasingly valued, portable energy storage power sources need to comply with environmental standards. RoHS directive certification restricts the use of harmful substances in products, while energy efficiency labeling certification requires products to meet certain requirements in terms of power consumption and energy utilization efficiency, in order to reduce energy consumption and negative impacts on the environment.
