Can I Bring Batteries on a Plane? 2026 Rules, Capacity Limits, and Packing Tips

Many travelers pack electronics like power banks, cameras, and electric toothbrushes when they head overseas. But did you know there are strict rules about bringing batteries on planes? If you break them, you could be denied boarding, fined, or even have your items confiscated. Trip.com breaks it all down with clear, detailed rules for every type of battery, so you can get prepped before takeoff and step on board with total peace of mind.

Batteries are considered dangerous goods—especially lithium batteries—which, if mishandled, can overheat, explode, or catch fire. To keep everyone safe in the air, airlines around the world and the International Air Transport Association (IATA) have clear rules on how batteries should be carried.

Common violations include:

• Power bank mistakenly placed in checked baggage
• Carrying batteries that exceed the capacity limit without declaring them
• Exposed batteries without proper packaging

Guidelines for Flying with Different Types of Batteries

🔋 Lithium batteries

• Under 100Wh: You can bring it onboard—keep it in your carry-on bag. The maximum number allowed varies by airline.
• 100–160Wh: You’ll need prior approval from the airline, and it’s usually limited to no more than 2 items.
• Over 160Wh: strictly prohibited from being brought on board.

🔋 Power banks (portable chargers on board)

Recently, safety incidents on planes involving power banks (portable chargers) have drawn widespread attention.

Hong Kong Civil Aviation Department's new regulations:

1. Don’t use power banks to charge devices during the flight: While the plane is in the air, passengers may not use power banks to charge phones, tablets, or other electronic devices, and you also can’t charge the power bank itself.

2. Don’t put power banks in the overhead bin or in checked baggage: Because they’re considered spare lithium batteries, power banks are carry-on only and should be stowed safely in your personal carry-on bag—not overhead—and never in checked luggage.

3. Carry-on only: All spare lithium batteries, including power banks, portable chargers, and similar devices, must be carried with you onto the plane and are not allowed in checked baggage.

📝 Travel tip: Before you board, remember to double-check.

• Make sure your power bank complies with your airline’s capacity rules (generally, you won’t need to declare it if it’s 100Wh or less).
• Keep it securely in your carry-on—and never take it out or use it during the flight.
• If you’re bringing more than one power bank, make sure the total number doesn’t exceed your airline’s allowance.

🔋 Dry cell batteries and nickel-metal hydride (NiMH) batteries

• Allowed in carry-on or checked baggage
• We recommend using the original manufacturer packaging or storing them separately in plastic bags to prevent short circuits.

How do You Fly with Batteries for Everyday Electronics?

Many travelers bring all kinds of electronics on board. Here are the carry-on guidelines for common devices and their batteries:

• Cell phones, tablets, and laptops: Devices with built-in lithium batteries may be carried with you; generally no declaration is required. We recommend turning them off or switching to airplane mode.
• Cameras and spare batteries: You can bring a few spare lithium batteries—we recommend each one be under 100Wh—and pack them separately in plastic bags.
• Electric toothbrushes/razors: If they use lithium batteries, they should be packed in your carry-on baggage, and the batteries must not be exposed.
• Drones: Keep the drone and any spare batteries in your carry-on bag. If a battery exceeds 100Wh, you’ll need airline approval.

Handy Packing and Organizing Tips for Flying with Batteries

• All removable batteries should be separated from the device and packed individually.
• Place exposed batteries in a fireproof pouch or a plastic protective case.
• Avoid packing batteries near the corners or pressure points of your luggage.
• Make sure the battery isn’t damaged or swollen and isn’t a counterfeit product.
