The certification model for mandatory certification of mobile power banks, lithium-ion batteries, and battery packs is: type testing + initial factory inspection + post-certification surveillance.

The above-mentioned post-certification supervision refers to a combination of two methods: follow-up inspections after certification and sampling and testing at the production site.

Except for power banks, lithium-ion batteries, and battery packs, the certification model is:

Mode One: Type testing + Post-certification supervision (for Class I or Class II equipment)

The above-mentioned post-certification supervision refers to one of the three methods: follow-up inspection after certification, sample sampling for testing or inspection at the production site, and market sampling for testing or inspection.

Mode Two: Type Testing + Post-certification Follow-up Inspection (for equipment other than Class I and Class II)
