China Power Bank Limit on Flights (2026 Guide)

Flying to China? Don’t get caught off guard at security. The China power bank limit is a small issue, but something every traveller should know. Let’s go through the basics so you can keep your devices powered during the trip.

China Power Bank Limit - Latest Update

Before you zip through security, here’s the latest: as of 28 June 2025, power banks without a clear 3C (CCC) certification label, or those that are vague or recalled, are now strictly banned on China domestic flights. 

Power banks lacking this certification, with unclear or missing 3C markings, or those from recalled batches, are strictly banned from being brought on board.

Even if your power bank meets capacity rules, it won’t be allowed aboard unless that 3C mark is crystal clear. 

What Is 3C Certification?

3C stands for China Compulsory Certification (sometimes written as CCC). It’s a safety mark that China requires on certain products. It’s a bit like the CE mark in Europe. For power banks, the 3C label means the product has passed official safety checks for things like battery quality, fire resistance, and overall reliability.

If your power bank doesn’t have a visible 3C mark, airport security in China can stop you from bringing it on board, even if the capacity is within the allowed limit.

👉Note: Besides the 3C mark, make sure all other information on your power bank is clear and legible, like the capacity in mAh or Wh and the brand/model details. Security staff will check these during screening, and unclear labels could lead to your power bank being confiscated.

China Domestic Flights vs International Flights

While the new regulation applies to all flights departing from mainland China, it does not affect flights arriving in China. That is:

✅Arriving from abroad: If you’re travelling from Singapore (or any other country) to China, your power bank is generally allowed on entry regardless of its certification status. Security won’t check the 3C mark for inbound passengers.

✅Departing domestic flights within China: Once you’re in China, things change. For any domestic flight in China, your power bank must have a clear 3C certification mark to be permitted on board. Oversized or uncertified units will be confiscated.

China Flight Power Bank Rules by Capacity

The Civil Aviation Administration of China (CAAC) sets the official rules for carrying power banks on flights. Here’s a quick breakdown based on capacity:

• Under 100Wh (up to about 20,000mAh): Allowed in your carry-on with no problem.
• 100Wh–160Wh (around 20,000mAh to 27,000mAh): Allowed, but usually limited to one or two units. Some airlines may require approval.
• Over 160Wh (above about 30,000mAh): Not allowed at all on China flights.

China Flight Power Bank Rules by Airline

While the CAAC sets the general rules for power banks on flights, individual airlines may have slightly different policies.

Tips for Carrying Power Banks on China Flights

Carrying a power bank in China isn’t complicated, but a few simple tips can save you a lot of stress at the airport:

1. Carry-on only – Never pack your power bank in checked luggage. Security will not allow it.

2. Check the capacity – Keep it under 100Wh (around 20,000mAh) for easier travel. For 100–160Wh, get airline approval.

3. Keep original labels visible – Make sure the capacity in mAh or Wh and the 3C certification mark are clearly visible. Security may refuse or confiscate power banks without proper labelling.

4. Limit the number – Most airlines allow only 1–2 high-capacity units. Avoid bringing extra chargers.

5. Keep it handy – Security may ask you to test your power bank, so don’t bury it at the bottom of your bag.

6. Know your airline rules – Check the specific carrier’s website if you’re flying China Eastern, Air China, Hainan, or low-cost carriers.

3. Transport planning – Check metro apps, high-speed train schedules, and airport transfers in advance.

4. Avoid peak crowds – Popular attractions and trains fill up quickly during holidays, especially during Golden Week and Chinese New Year. Book tickets early or travel during off-peak times.
