Power banks have had a safety problem for years. Cheap cells, inflated capacity claims, fire risks — the market has been loosely regulated and consumers have paid the price. China just changed that with its
first mandatory national standard for mobile power sources, published March 31 and taking effect April 1, 2027.
This is a significant regulatory shift. Here's what it actually requires.
Key Points
- China published its first mandatory national safety standard for power banks on March 31, 2026 — full implementation begins April 1, 2027
- All power bank battery cells must pass a needle-puncture test — no fire or explosion permitted even when physically pierced
- Stricter thermal abuse testing with higher temperatures and longer durations than previous voluntary standards
- Mandatory drop tests, compression tests, overcurrent protection, and short-circuit protection across all devices
- Manufacturers must clearly label safe service life — addressing the widespread mislabeling and fake capacity problem directly
- 28 major battery companies including ATL, BYD, and Lishen already in preliminary testing
The Needle-Puncture Test Is the Critical One
Battery fires happen when cells are damaged — dropped, compressed, or punctured. A needle-puncture test simulates exactly that worst-case scenario. If a cell catches fire or explodes when punctured, it fails. Full stop.
This test weeds out the cheap, low-quality cells that have dominated the budget
power bank market for years. Passing it requires genuinely safer battery chemistry and construction — you can't fake your way through a needle in a cell. Manufacturers using inferior cells to hit low price points will either upgrade their components or exit the market entirely.
That's the point.
Fake Capacity Claims Get Addressed Too
Anyone who has bought a budget power bank knows the drill. The label says
20,000mAh. Real-world performance suggests something considerably less. The new standard mandates clear, accurate labeling of both capacity and safe service life.
Enforcing accurate capacity claims removes one of the most common consumer deceptions in the category. A power bank that actually delivers what it says on the packaging is a better product regardless of everything else.
The Industry Is Already Moving
Twenty-eight major battery cell manufacturers — including ATL,
BYD, Lishen, and Huizhou Marathon — participated in preliminary testing before the standard was even fully published. Five chip and BMS solution companies have already passed initial bottom-up tests. That level of industry engagement before mandatory implementation suggests manufacturers are treating this seriously rather than waiting until the last moment.
With a year between publication and enforcement, the preparation window is reasonable. The companies that start now will be ready. The ones that don't will scramble.
Consumer power banks in China are about to get genuinely safer. That's not a small thing given how many millions of these devices are in daily use.
