Technical FAQs 4

What does 3C certification mean for power banks?

3C certification, short for China Compulsory Certification, is a legal safety requirement for electronics sold or used in China—including power banks. Since 2025, any power bank without a 3C mark is banned from domestic flights and retail shelves. This isn't just a formality.

What Is 3C Certification? 3C certification, short for China Compulsory Certification, is a legal safety requirement for electronics sold or used in China—including power banks. Since 2025, any power bank without a 3C mark is banned from domestic flights and retail shelves.

Should you buy a 3C battery?

What you pay extra for is peace of mind—tested battery cells, fire-resistant casing, and better lifespan. Cheap, uncertified models may cost less upfront, but fail fast. Plus, they might get confiscated at airports or stations. If you’re traveling around China for even a week, spending a bit more for 3C isn’t just smart—it’s necessary.

Is a 3C battery safe in China?

Key Highlights: Only 3C is accepted for legal sales and transport in China. CE is a general entry ticket for EU markets, but does not test for lithium battery thermal runaway. FCC focuses on whether the device emits safe levels of radio waves—not physical safety.
