Short answer: For mainland China departures or transit, a power bank can need a valid China 3C mark in addition to being under the Wh limit. A battery under 100 Wh can still be refused at the airport if required 3C evidence is missing or unclear.
China airport screening is one of the most important country-specific power-bank cases because it can depend on a visible certification mark, not only Wh.
The device label matters. If the mark is missing, damaged, or not clearly tied to the device, a marketplace listing or generic brand claim may not be enough for frontline screening.
CertiWatt treats the 3C condition as a route overlay. It should affect mainland China departure and transit scenarios without changing unrelated trips.

Can a power bank under 100 Wh be banned at a China airport?
Yes. If required 3C evidence is missing, the device can be refused even if the Wh value is under 100.
Does 3C apply to flights outside China?
No. CertiWatt applies the China 3C overlay to relevant mainland China departure or transit scenarios.
Is a product-page certification claim enough?
A visible mark on the device is stronger. Official manufacturer documentation can help, but staff may still inspect the physical label.
Which models are safer for China trips?
Models with clear cataloged 3C evidence and visible device markings are stronger candidates than models with unknown certification status.
