Power bank with a '3C' label. Image by Billy Jiang/That's Short for China Compulsory Certification, the '3C' label is a mandatory safety standard for electronics sold and used in China. Manufacturers have been required to secure 3C certification for power banks since August 1, 2024, but enforcement largely targeted factories and retailers.

How much does a 3C power bank cost?

A: Not really. Prices have dropped a lot since the 2025 rules kicked in. You can find 3C power banks starting from 79 RMB (around $11) on JD.com or Pinduoduo. 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.
