China Power Bank Guide: Rules, Buying & Rental
Everything about power banks in China — airline rules, where to buy, and delivery service.
Traveling in China means long train rides, full-day sightseeing, and constant phone use for maps, translation, and payments. A power bank is essential — but China has strict rules about what you can bring on flights and trains. This guide covers everything you need to know about using and buying power banks in China as a foreigner.
China's Power Bank Rules for Flights
China's Civil Aviation Administration (CAAC) enforces strict rules on power banks (portable chargers). These rules apply to all domestic and international flights departing from Chinese airports:
Key Rules to Remember
- Carry-on only — power banks are banned in checked luggage
• Max 2 units per passenger
- Labels must be clearly visible — capacity (Wh or mAh) and voltage must be legible
- No in-flight use — you cannot use power banks to charge devices during the flight
• 3C mark required for domestic flights (since June 2025)
How to Calculate Watt-Hours (Wh)
Most power banks list capacity in milliamp-hours (mAh). To convert to watt-hours:
Why Buy a Power Bank in China?
Many travelers bring their own power bank from home — but there are good reasons to buy one locally:
- 3C Certification: Power banks bought in China come with the 3C mark, guaranteeing they pass airport security on domestic flights.
- Affordable Prices: China is the world's largest producer of portable chargers. Top brands like Xiaomi, PISEN, and Anker cost 30–50% less here than abroad.
- No Language Barrier: Chinese power banks come with Chinese/English labels showing capacity and voltage — perfect for airport security checks.
- High Quality: Chinese brands dominate the global market. You're getting the same products sold worldwide, just cheaper.

FAQ: Power Banks in China
Can I bring my own power bank from home?
Yes, but it must have clear capacity labels (mAh or Wh) and be under 100Wh for easy approval. Since June 2025, domestic flights also require a 3C mark. If your power bank doesn't have the 3C logo, it may be confiscated at domestic airport security.
What if my power bank gets confiscated?
Airport security will offer you options: voluntary surrender, mailing it to your home address (if available), or temporary storage (up to 7 days at some airports). Prevention is easier — buy a 3C-certified one locally!
Can I charge my phone on the flight using my power bank?
Officially, CAAC rules prohibit using power banks during flight. Keep it switched off and stored in your carry-on bag under the seat. Some airlines may be lenient, but it's best to follow the rules.
Are power banks available in Chinese stores?
Yes — electronics stores, convenience stores, and vending machines in train stations all sell power banks. However, prices in tourist areas and airports are often 2–3× higher than online. Our delivery service offers fair, transparent pricing.
What about train travel?
China's high-speed trains have power outlets at every seat (or between seats). You may not need a power bank for train travel. However, for buses, hiking, and outdoor activities, a power bank is essential.

| Capacity | Allowed? | Requirements |
| ≤ 100Wh (≈27,000mAh) | ✅ Yes | No approval needed. Carry-on only. Must have clear labels. |
| 100–160Wh (≈27,000–43,000mAh) | ⚠️ With approval | Airline approval required 12–48 hours before flight. Max 2 units. |
| > 160Wh (≈43,000mAh+) | ❌ No | Completely prohibited on passenger aircraft. |
Practical Tips
- Formula: Wh = (mAh × Voltage) ÷ 1000 Most power banks use 3.7V lithium cells. So: • 10,000mAh = 37Wh ✅ • 20,000mAh = 74Wh ✅ • 27,000mAh = 99.9Wh ✅ (just under the limit) • 30,000mAh = 111Wh ⚠️ (needs airline approval)
- 💡 Tip: Tell us your check-out date and we'll make sure the power bank arrives before you need it. If you're traveling to multiple cities, we can arrange delivery to each hotel.
