POWER banks have become an indispensable travel companion, ensuring our devices remain charged throughout long flights and layovers.
However, as convenient as they are, power banks contain lithium batteries, which can pose fire hazards if not handled properly. For this reason, airlines and aviation authorities have strict regulations on carrying power banks onboard.
If you are planning a trip and wondering whether your power bank meets safety requirements, this guide will provide everything you need to know about flying with one.
From understanding air travel restrictions to essential safety tips, here is how to ensure a hassle-free journey with your power bank.
1. Know the rules: Can you bring a power bank on a plane?
Yes, you can bring a power bank on a plane, but only in your carry-on luggage—never in checked baggage. This rule is set by the International Air Transport Association (IATA) to minimise fire risks in cargo holds, where incidents would be harder to manage.
Additionally, power banks must comply with airline regulations regarding capacity:
- Power banks under 100Wh: Allowed without restrictions.
- Power banks between 100Wh and 160Wh: Require airline approval, usually limited to two per passenger.
- Power banks over 160Wh: Generally prohibited unless for medical equipment.
2. Choose a safe and certified power bank
Not all power banks are created equal. To avoid potential safety hazards, always purchase a power bank from a reputable brand that meets industry safety standards.
- Conformite Europeenne (CE): Ensures compliance with European safety standards.
- Federal Communications Commission (FCC): Required for devices sold in the United States (US).
- Restriction of Hazardous Substances (RoHS): Indicates the product is free from toxic materials.
- UN38.3 Certification: Confirms the battery has passed safety tests for air transport.
Additionally, opt for power banks with built-in safety features, such as:
- Overcharge protection
- Short-circuit protection
- Overheat protection
- Automatic shut-off
These features help prevent overheating, fires or explosions during use.
3. Pack your power bank the right way
To ensure your power bank complies with airline safety regulations, follow these packing guidelines:
- Carry it in your hand luggage: Placing power banks in checked bags is strictly prohibited.
- Use a protective case or sleeve: Prevents accidental damage or short circuits.
- Keep it away from metal objects: Coins, keys and paper clips can cause short-circuiting if they come into contact with the terminals.
- Store it in an easy-to-access place: Security officers may need to inspect it separately at the airport.
If your power bank has an on/off switch, ensure it's turned off before boarding.
4. Charge your power bank responsibly
Improper charging is one of the leading causes of power bank malfunctions. To charge your power bank safely:
- Avoid overcharging: Disconnect the charger once it reaches 100 per cent.
- Use the correct charging cable and adapter: Only use accessories provided by the manufacturer or ones that meet the same specifications.
- Never charge on flammable surfaces: Avoid charging on beds, couches or carpets where heat can build up.
- Unplug immediately if it overheats: If your power bank feels unusually hot, stop charging and let it cool down before using it again.
5. Store your power bank properly
When not in use, store your power bank in a cool, dry place away from direct sunlight and extreme temperatures. High temperatures can degrade the battery, while exposure to moisture can cause short-circuiting. Therefore, avoid leaving it in a hot car as the interior of a parked car can exceed 50°C (122°F), leading to battery swelling or explosion.
If you are not planning to use your power bank for an extended period, charge it to around 50 per cent before storing it. Lithium-ion batteries degrade faster when stored at zero per cent or 100 per cent charge.
6. Be aware of real-life incidents
Several incidents have occurred where power banks caused fires onboard planes, leading to emergency landings or delays. Some common causes include:
- Short-circuiting: Due to contact with metal objects in bags.
- Crushing damage: Power banks crushed under seats have overheated and caught fire.
- Defective or counterfeit batteries: Poorly made batteries have combusted unexpectedly.
To minimise risks, always buy from trusted brands, follow safety guidelines and be mindful of how you handle and store your power bank.
7. What to do if your power bank does not comply with regulations?
If your power bank exceeds airline restrictions or is in poor condition, you have a few options:
- Leave it at home: If you do not need it for your trip, avoid the hassle altogether.
- Ship it separately: Some airlines allow passengers to mail their power banks instead of bringing them on board.
- Buy a compliant one: Purchase a smaller-capacity power bank that meets airline regulations.
- Dispose of it properly: Old or damaged power banks should be recycled at a designated battery disposal facility.
Travel smart and stay safe
Power banks are a travel essential, but their lithium-ion batteries require careful handling, especially on flights.
By understanding airline regulations, choosing high-quality products and following proper safety practices, you can ensure a smooth and trouble-free journey.
Before your next flight, double-check your power bank’s capacity, pack it safely in your carry-on and follow these tips to stay powered up while keeping safety a priority.
