With electronic devices now an essential part of travel, many passengers wonder: Can I bring batteries on a plane? Whether it’s your smartphone, laptop, camera, or power bank, most of these devices contain batteries—especially lithium-based ones. While most batteries are allowed, there are strict rules depending on the type and capacity. This guide summarizes the latest battery regulations for air travel in 2025 to help you pass security checks without trouble.
1. What Types of Batteries Are Allowed on Planes?
According to the International Air Transport Association (IATA), the U.S. FAA, and China Civil Aviation Administration, the following battery types are generally permitted in carry-on baggage. Some are restricted by quantity or watt-hour rating:
✅ Allowed Battery Types:
• Lithium-ion batteries (phones, laptops, cameras)• Nickel-metal hydride (NiMH) batteries (rechargeable AA/AAA)
• Alkaline batteries (AA, AAA, C, D, etc.)
• Lithium metal batteries (coin/button cells)
2. Lithium Battery Capacity Limits
Lithium batteries are the most tightly regulated due to potential fire risks. Limits are based on watt-hour (Wh) capacity:
| Watt-Hour (Wh) Rating | Allowed? | How to Carry | Notes |
| ≤ 100Wh | ✅ Yes | Carry-on only | Phones, tablets, cameras, laptops |
| 100Wh–160Wh | ✅ Yes | Carry-on (max 2 pcs) | Airline approval required (e.g., drones) |
| > 160Wh | ❌ No | Not allowed | Large power tools, e-bikes, etc. |
⚠️ Important Notes:
• Spare lithium batteries are prohibited in checked luggage.• Batteries must be properly insulated and protected from short circuits—use original packaging or battery cases.
3. Can You Bring a Power Bank on a Plane?
Yes, but there are restrictions.
According to IATA and Chinese aviation regulations:
• ≤100Wh (approx. 27,000mAh): Allowed in carry-on.• 100–160Wh (27,000–43,000mAh): Allowed with airline approval.
• Not allowed in checked luggage under any circumstances.
• A maximum of two power banks over 100Wh is allowed per passenger.
• The capacity must be clearly labeled. Unmarked batteries may be confiscated.
4. Carry-On vs Checked Luggage: What's the Difference?
| Battery Type | Checked Luggage | Carry-On | Notes |
| Batteries in devices | ✅ Yes | ✅ Yes | e.g., phone, laptop |
| Spare lithium batteries | ❌ No | ✅ Yes | Must be insulated and well-packed |
| Power banks | ❌ No | ✅ Yes | Only within power limits |
| AA/AAA (non-lithium) | ✅ Yes | ✅ Yes | Preferably in original packaging |
5. Special Notes for International Flights
Airline and country-specific rules may differ. It’s always a good idea to double-check before flying:
• Check your airline’s official website or customer support.• Visit the IATA website for global regulations.
• Refer to local civil aviation authorities (e.g., CAAC, FAA).
For example:
• U.S. TSA prohibits spare lithium batteries in checked luggage.• EU carriers typically restrict high-capacity battery devices in hold baggage as well.
6. Summary: Tips for Flying Safely with Batteries
1. Check the battery label, especially for power banks.
2. Always carry spare batteries in your cabin luggage.
3. Use proper packaging to prevent short circuits.
4. Confirm rules with your airline, especially for international travel or when carrying drones, cameras, or large devices.
FAQ
Q1: Can I bring two power banks on a plane?
Yes, as long as they are both under 100Wh and clearly labeled.
Q2: Can I carry drone batteries on board?
Yes, if each battery is under 160Wh. Airline approval may be needed.
Q3: Can I check in batteries for electric scooters or tools? No. Batteries over 160Wh are not allowed on passenger flights at all.
