China Power Bank Rules 2025: What Muslim Travellers Must Know Before Flying

A power bank is something many travellers carry without thinking. It sits in a backpack or handbag, ready to charge your phone during long layovers or a day out exploring. But in China, this everyday item has now become a potential problem at airport security.

As of June 28, 2025, China has introduced a new rule for all domestic flights: only power banks with a visible 3C certification mark are allowed onboard. This change was announced with only two days’ notice, and many passengers—locals and tourists alike—were caught off guard. Thousands of power banks have already been confiscated at security checkpoints.

If you're a Muslim traveller planning to visit China, here's what you need to know to avoid inconvenience and travel smoothly.

What Is 3C Certification?

The 3C mark stands for China Compulsory Certification, a mandatory safety label for electronic products in China. It’s similar to the CE mark in Europe or UL certification in the US.

For power banks, this rule became mandatory in August 2023. So, if you purchased your power bank before 2024 or bought it outside of China, there’s a high chance it does not have the required 3C logo.

If your power bank doesn’t have this clearly printed on its body, it will not be allowed on domestic flights in China—even if the size or capacity is within normal limits.

Why Most Power Banks Are Still Not Accepted

You might think your power bank is fine because it’s made in China. But many products made in China for international sale do not include the 3C mark, since it's only required for items sold within China.

Even popular models bought online or from trusted electronics stores may not be accepted if the certification is missing. Unless your power bank was made after mid-2023 and shows the 3C mark, it may be confiscated at the airport.

What About Popular Brands Like Anker?

Well-known brands like Anker are also affected. In fact, Anker recalled over a million power banks recently due to overheating risks. Many of their earlier models don’t have the 3C mark, especially those sold outside of China.

So even if your power bank is from a famous or expensive brand, it could still be rejected. What matters now is not the brand, but whether the 3C certification is there.

Power Bank Size & Capacity Limits

The usual rules about battery size still apply:

• Power banks must be in your carry-on bag, not in checked baggage.

• Under 100Wh: Allowed only if 3C-certified.

• 100Wh to 160Wh: You need special airline approval.

• Over 160Wh: Completely banned.

If your power bank doesn’t list its Wh rating, you can calculate it using this formula:

Wh = (mAh × Voltage) ÷ 1000

For example, a 20,000mAh power bank at 3.7V = 74Wh.

Note: Even if the size is okay, no 3C = no boarding.

Can You Use Power Banks on the Plane?

It depends on the airline. Many Chinese airlines now prohibit in-flight use of power banks, even if they’re certified. This is due to past battery incidents, such as overheating or smoke in the cabin.

Unless the crew gives you permission, it’s safest not to use your power bank during the flight.

How About International Flights?

Officially, this rule is for domestic flights inside China. But some travellers on international flights (e.g., departing from Shanghai or Beijing) have also had their power banks taken away.

Enforcement may vary depending on the airport and staff. So, even if you're flying into or out of China, it's best to follow the same rules to avoid problems.

Before flying, take a few moments to prepare:

• Check for the 3C mark on your power bank. If it’s missing, do not bring it.

• Carry your power bank in your hand luggage, never in checked bags.

• Make sure it's under 100Wh, or get airline approval for larger devices.

• Avoid using your power bank during the flight unless the crew allows it.

• If you're unsure, buy a certified power bank in China after arrival.

A Note for Muslim Travellers

China offers rich cultural experiences and beautiful destinations, including some historical Islamic sites and Muslim-friendly cities like Xi’an and Urumqi. But airport policies can be strict, especially on electronics. To avoid missing prayer times, delays, or long security checks, make sure your devices follow the rules—including your power bank.

Power banks are useful tools for travellers—but in China, they are now under tighter control. This rule may feel sudden, but it’s meant to protect everyone’s safety during air travel.

If you’re planning to fly in or out of China soon, take a few minutes to inspect your power bank today. It could save you time, stress, and possibly a lost device at the airport.
