Can I bring a portable charger to China?

Yes, you can bring a portable charger to China, but there are strict rules for domestic flights. Since June 28, 2025, all portable chargers carried on domestic flights within China must have a clear and valid CCC (China Compulsory Certification) mark. Portable chargers without this mark, with unclear marks, or that have been recalled are prohibited on domestic flights. For international flights to and from China, the rules are less strict regarding CCC marks, but the standard watt-hour limits still apply.

  • China (Domestic Flights): Portable chargers must have a clear and valid CCC mark. Chargers without this mark, with unclear marks, or recalled models are banned. The CCC mark must be printed on the device itself, not just the packaging.
  • China (International Flights): Portable chargers purchased overseas through legitimate channels and meeting the watt-hour requirements are permitted. The CCC mark requirement does not apply to international and regional flights in the same way.
  • Capacity Limits: Portable chargers under 100Wh (approximately 27,000mAh) can be carried without approval. 100Wh to 160Wh requires airline approval, with a maximum of two per person. Over 160Wh is prohibited.
  • Carry-On Only: Portable chargers must be carried in hand luggage only. They are strictly prohibited in checked baggage on all flights.
  • China (Trains): On high-speed trains and regular rail services, portable chargers must have clear markings and a rated energy not exceeding 100Wh (27,000mAh). The CCC mark is not mandatory for rail travel.
  • In-Flight Use: Using or recharging portable chargers during flights is prohibited on many Chinese airlines, following global aviation safety standards.

Detailed Answer

Why China Requires CCC Certification

China implemented mandatory CCC certification for portable chargers starting August 1, 2024. Products without CCC certification cannot be manufactured, sold, imported, or used in business activities in China. This requirement was introduced to improve product safety and traceability.

Following several aviation incidents involving portable chargers, the Civil Aviation Administration of China issued an emergency notice effective June 28, 2025, prohibiting passengers from carrying portable chargers without CCC marks, with unclear marks, or from recalled batches on domestic flights. The rule is strictly enforced at security checkpoints across all Chinese airports.

New Digital Traceability Requirements

Starting March 1, 2026, newly certified portable chargers must include a traceable QR code alongside the CCC mark. This QR code serves as a digital ID for the product, allowing consumers and inspectors to verify the certificate number, manufacturer, model, and production date. The QR code must be inseparable from the CCC mark and clearly readable.

There is a one-year transition period. From March 1, 2027, all portable chargers must have the CCC mark with the traceable QR code before they can be manufactured, sold, imported, or used. Products already in the market with the standard CCC mark before March 1, 2027, do not need to be updated.

Capacity Limits and Watt-Hour Rules

The watt-hour (Wh) rating remains the core regulatory metric for air travel. The rules are:

  • Under 100Wh: Allowed without airline approval. A typical 20,000mAh portable charger rated at 5V calculates to 100Wh (5 × 20,000 ÷ 1000 = 100), which meets the standard.
  • 100Wh to 160Wh: Requires airline approval, with a maximum of two units per passenger.
  • Over 160Wh: Strictly prohibited on all flights.

Passengers should check the rating on their device before travel. If only mAh is listed, calculate Wh using the formula: Wh = (mAh × voltage) ÷ 1000. Most portable chargers use 3.7V or 5V.

Domestic vs. International Flights

The CCC verification standard applies to domestic flights within China. If your itinerary includes a domestic connecting flight, security will strictly check for the CCC mark at the domestic transfer checkpoint. Non-compliant chargers will be intercepted even if you were allowed to carry them on the international segment.

For international and regional flights arriving in or departing from China, the rules are more flexible. Portable chargers purchased through legitimate overseas channels and meeting the watt-hour requirements are generally permitted. The CCC mark requirement is not applied as strictly to these flights.

Rail Travel in China

China's railway regulations differ from aviation rules. For high-speed trains and regular rail services, portable chargers must have clear markings and a single-unit rated energy not exceeding 100Wh (27,000mAh). The CCC certification is not a mandatory check for rail passengers. However, damaged, bulging, or poorly labeled chargers are prohibited.

Like air travel, portable chargers must be carried in hand luggage or on your person. They cannot be placed in checked luggage.

What to Do If Your Charger Is Not Compliant

If you arrive at a Chinese airport security checkpoint with a non-compliant portable charger, you have three options:

  • Ask a friend or family member to take it back. If someone accompanied you to the airport, they can take the charger home.
  • Use airport courier service. Most airports have dedicated courier counters where you can mail the charger to an address within China.
  • Use the airport storage service. Some airports offer temporary storage for a limited period. At Beijing Capital Airport, non-compliant chargers can be stored free for up to 7 days. Unclaimed items are disposed of after the storage period expires.

Real Traveler Experiences

"I had no idea my portable charger needed a CCC mark for domestic flights in China. Security confiscated it at the transfer in Beijing. I had to buy a new one at the airport. Now I always check before flying." US traveler, forum post

"My Anker power bank has the CCC mark, so I had no issues on domestic flights within China. The security officer just glanced at it and waved me through." UK traveler, travel review

"Flying from Hong Kong to Shanghai, my portable charger was fine. But when I transferred to a domestic flight to Xi'an, they checked for the CCC mark. Mine did not have it, so I had to leave it at the airport storage." Australia traveler, forum post

"On the high-speed train from Beijing to Shanghai, nobody asked about CCC certification. They just looked at the watt-hour rating. My 20,000mAh charger was fine." Canada traveler, Reddit

Pro Tips

  • Check your portable charger for a clear CCC mark before traveling to China for domestic flights
  • If your charger lacks the CCC mark, consider buying a compliant one locally or leaving it at home
  • Never pack portable chargers in checked luggage. They must be in your carry-on
  • Calculate the watt-hour rating if only mAh is listed: Wh = (mAh × voltage) ÷ 1000
  • For domestic transfers within China, expect strict CCC verification even if your international flight did not require it
  • Carry only one or two chargers under 100Wh each to avoid approval requirements
  • For rail travel, the CCC mark is not required, but the 100Wh limit and clear labeling are enforced
  • Arrive early at the airport to allow time for additional security checks on electronics

Can I use my phone charger internationally?

Yes, you can use your phone charger internationally. In most cases, you only need a plug adapter, not a voltage converter. Modern phone chargers are almost always dual voltage, meaning they can handle the different electrical currents used around the world. However, you must check your charger's label and have the correct plug shape for your destination. Most phone chargers are dual voltage: look for "INPUT: 100-240V, 50/60Hz" on the charger block to confirm You need a plug adapter to change the shape of your plug, not a voltage converter Plug types vary by region: Type A/B (US, Japan, Canada), Type C/F (Europe), Type G (UK, Ireland, Singapore, UAE), Type I (Australia, China) Universal travel adapters with built-in USB ports are the most convenient solution for international charging High-power devices like hair dryers and straighteners often need voltage converters; do not assume they are dual voltage Need data abroad?
