China Power Bank Limits on Flight: Capacity, Rules, 3C Certification

In China, passengers are allowed to bring up to 2 power banks in carry-on bags only, with a capacity under 100Wh and valid 3C certification. Those between 100Wh and 160Wh need airline permission, and power banks are completely banned in checked luggage.

How to Calculate Watt-Hours

China's power bank regulations are based on watt-hours (Wh), not milliampere-hours (mAh). Here's how to understand the limits: Formula: Wh = (mAh × Voltage) ÷ 1000. Most power banks operate at 3.7V, so:

• 10,000mAh = (10,000 × 3.7) ÷ 1000 = 37Wh
• 20,000mAh = (20,000 × 3.7) ÷ 1000 = 74Wh
• 27,000mAh = (27,000 × 3.7) ÷ 1000 = 99.9Wh (just under the limit)
• 30,000mAh = (30,000 × 3.7) ÷ 1000 = 111Wh

Important Capacity Notes

• 100Wh limit: Most standard consumer power banks (10,000mAh to 20,000mAh) fall comfortably under this limit
• 160Wh limit: Power banks between 100-160Wh require advance airline approval and are limited to 2 units per passenger
• Label visibility: Power banks must have clearly legible capacity markings. Unmarked or damaged labels may result in confiscation

China Power Bank Limit - What is the "3C Certification" Rule?

As of August 1, 2024, China has moved lithium-ion power banks into the China Compulsory Certificate (3C or CCC) management system. Even if your power bank says "Made in China," it likely does NOT have 3C certification. Products manufactured for export markets carry CE (Europe) or FCC (US) marks, but not the CCC mark required for China domestic flights. Only power banks specifically manufactured for the Chinese domestic market display the 3C logo.

• For Residents/Local Purchases: All power banks sold in China must have the 3C mark.
• For International Travelers: You do not need a 3C mark on a device bought in India or elsewhere. However, you must have a clear, legible manufacturer's label showing the capacity (Wh or mAh) and voltage. If the label is rubbed off or "homemade," it will be confiscated at airport security.

Latest New Rules About China Power Bank Limits

The rules for power bank in China has changed dramatically. Here's what you need to know about the most recent updates:

March 2026: New ICAO International Standards

On March 27, 2026, the International Civil Aviation Organisation (ICAO) implemented new global safety specifications affecting all international flights:

• Maximum 2 power banks per passenger on international flights
• No charging devices from power banks during flight
• Power banks cannot be stored in overhead bins (must be in seat pocket or under seat)

These rules were approved by all 36 ICAO Council member states and apply to all 193 member countries following a series of lithium battery incidents, including an Air China Flight CA139 incident in October 2025 where a battery ignited in an overhead locker.

June 2025: China's Strict 3C Enforcement

Since June 28, 2025, the Civil Aviation Administration of China (CAAC) has strictly enforced 3C certification requirements for domestic flights. Airport security now actively checks for the CCC (3C) mark, and non-compliant devices face immediate confiscation.

January 2026: India's DGCA Updates

India's Directorate General of Civil Aviation (DGCA) issued new restrictions in January 2026, banning in-flight power bank charging and requiring power banks to remain in passenger possession (not overhead bins).

China Power Bank Limit - Limitations You Might Not Know

Beyond capacity, China enforces three "invisible" rules that often catch travelers off guard:

• The "No-Use" Rule: On many Chinese domestic flights (e.g., Air China, China Southern), you are strictly prohibited from using your power bank to charge devices while the plane is in the air.
• Strictly No Checked Bags: This is a universal rule, but in China, if a power bank is found in a checked bag via X-ray, the bag will be pulled, opened, and delayed.
• The 2-Unit Cap: Even if your power banks are small (e.g., two 5,000mAh units), you are generally capped at two units total per passenger.

China Power Bank Rules for Different Flight Types

The power bank rules vary significantly depending on your flight type:

Domestic Flights Within China

Requirements:

• ✅ 3C certification mandatory – power bank must display the CCC logo
• ✅ Under 100Wh: No approval needed
• ✅ 100-160Wh: Airline approval required
• ❌ Over 160Wh: Prohibited
• ✅ Must be in carry-on luggage only (never checked baggage)
• ❌ Cannot use power banks to charge devices during flight

International Flights Departing from China

Requirements:

• ✅ 3C certification required (domestic rules apply at departure security)
• ✅ Same capacity limits as domestic flights
• ✅ Must follow new ICAO rules (max 2 power banks, no in-flight charging, no overhead bin storage)

International Flights Arriving in China

Requirements:

• ✅ No 3C inspection upon entry – you can enter China with non-CCC power banks
• ⚠️ BUT: If you plan to take any domestic flights within China later, your power bank will be confiscated without 3C certification

Connecting Flights Through China

Critical Rule: If your itinerary includes a domestic connection (e.g., Tokyo → Shanghai → Chengdu), the Shanghai to Chengdu segment is treated as a domestic flight. Your power bank must have 3C certification to pass security.

On All Flights (International & Domestic)

• ❌ No In-Flight Charging: You cannot use power banks to charge phones, tablets, or laptops at any time during the flight
• ❌ No Overhead Bin Storage: Power banks must remain in your seat pocket or under the seat in front of you—never in overhead compartments
• ❌ No Checked Baggage: All power banks and spare lithium batteries must be in carry-on luggage only
• ❌ Keep Switched Off: If your power bank has a power switch, it must be turned off during flight

Additional Restrictions

• ❌ No Charging Power Banks from Aircraft Outlets: You cannot recharge your power bank using in-seat power systems
• ❌ No Damaged or Recalled Units: Power banks from recalled batches are prohibited regardless of certification
• ❌ No Unclear Labels: Power banks with faded, damaged, or unclear 3C markings may be confiscated
