My China Travel Prep: Don't Let Airport Security Confiscate Your Power Bank!

I’m flying to China soon, and my itinerary involves an international arrival followed by a domestic connecting flight. I've been doing my research, and let me tell you, the power bank rules are a little stricter than the usual international standards. If you're planning a similar trip, you need to pay close attention to one specific certification mark to avoid having your gear confiscated!

Here’s everything I learned and the products I’m considering buying (using my affiliate links!) to ensure a stress-free experience.

Rule 1: Carry-On is the ONLY Way

First and foremost, like most global airlines, the Civil Aviation Administration of China (CAAC) requires all power banks to be carried in your carry-on baggage or on your person. They are strictly banned from checked luggage due to the fire risk from lithium-ion batteries.

Rule 2: Capacity Limits (The Usual Stuff)

The capacity rules are pretty standard internationally:

• Under 100 Wh (~20,000 to 27,000 mAh): Perfectly fine. Most everyday power banks fall here.
• 100 Wh to 160 Wh: Requires prior airline approval. You'll need to contact your carrier in advance.
• Over 160 Wh: Strictly prohibited.

For my trip, I'm sticking to a reliable 10,000mAh or 20,000mAh unit to avoid any hassle.

Rule 3: The China-Specific "3C" Mark

This is the big one and the main reason I'm likely buying a new power bank. As of June 28, 2025, any power bank carried on a domestic flight within mainland China must have a clear, visible China Compulsory Certification (3C or CCC) mark printed on the device itself.

• My Situation: I land internationally, pass through customs, and then check in for a domestic flight. That second security check is where the 3C rule is enforced.
• The Problem: Many high-quality, internationally-certified power banks (even those "Made in China" for export) do not have this specific Chinese domestic safety mark.
• The Risk: If it doesn't have the 3C logo, security can and will confiscate it, regardless of capacity or international certifications like CE or FCC.

My Product Recommendations (Affiliate Links)

Since my current gear doesn't have the 3C mark, I’m looking at reputable brands known to sell compliant products. My strategy is to buy one online before I go to make sure it arrives in time, or I might just buy a trusted local brand once I land in China.

Here are a few 3C-certified options that have been recommended in my research. (As an affiliate, I may earn from qualifying purchases):

• Xiaomi Power Bank 33W (10,000mAh): A local favorite that airport security instantly recognizes. It offers fast charging and is highly portable. [Link to Product]
• Anker 525 Power Bank (20,000mAh): A trusted global brand with specific models that carry the CCC mark. Great for long days out. [Link to Product]
• LISEN 22.5W Power Bank (10,000mAh): This one boasts global certifications, including 3C, and an ultra-slim design which is appealing for travel. [Link to Product]

Make sure when you buy that you confirm the CCC logo is printed on the physical device, not just on the box or a sticker that can fall off.

Before You Fly

1. Check the Mark: Look for the little "3C" logo on your power bank now.
2. Verify Capacity: Ensure it's under 100 Wh.
3. Keep it Off: You aren't allowed to use or charge power banks during the flight anyway.

Following these steps should ensure you keep your devices charged and pass through airport security without a hitch!

Have you had any experiences with this specific 3C rule? What brands did you use?
