Last Updated: March 2026 | Policies are based on TSA and IATA guidelines. Always verify with your airline before travel.
Yes, you can bring a power bank on a plane, but it must be packed in your carry-on baggage. TSA and international aviation safety rules prohibit lithium battery power banks in checked luggage because of fire risk. The rules apply regardless of airline or destination. What matters is the capacity of your power bank, measured in watt-hours (Wh), and how many you are carrying.
The most important rule is simple: power banks must travel in carry-on luggage and must meet airline battery capacity limits.
This guide covers TSA rules for lithium batteries, carry-on battery policy, size and capacity limits, and what to expect at airport security.
TSA and IATA Rules for Power Banks
According to TSA guidance, spare lithium batteries such as power banks must be carried in cabin baggage and are not permitted in checked luggage because of fire safety risks. The IATA (International Air Transport Association) has also enforced limitations regarding battery capacity:
How to Calculate Power Bank Watt-Hours (Wh)
Most power banks show their capacity in mAh (milliamp-hours) rather than watt-hours. Airlines and airport security use the Wh rating to determine whether a battery is allowed on a flight.
To estimate watt-hours:
Wh = (mAh × Voltage) ÷ 1000
Most power banks show their capacity in mAh (milliamp-hours) rather than watt-hours. Airlines and airport security use the Wh rating to determine whether a battery is allowed on a flight.
To estimate watt-hours:
Wh = (mAh × Voltage) ÷ 1000
Power Bank Size and Capacity Limits (Quick Guide)
- • Under 100 Wh — Allowed in carry-on baggage without airline approval.
- • 100–160 Wh — Allowed in carry-on, but airline approval is usually required, and quantity may be limited.
- • Over 160 Wh — Not permitted on passenger aircraft.
Carry-On Battery Policy
Airlines maintain strict policies regarding carry-on batteries in the interests of passenger safety. Most major carriers restrict:
- A maximum of two spare power banks over 100 Wh per passenger.
- Power banks must be protected individually, possibly in their original packaging or with terminals taped to prevent short circuits.
- Power banks are generally not permitted in checked baggage because lithium batteries can pose a fire risk.
Flight Packing Tips for Power Banks
To avoid issues at airport security, consider the following travel tips:
- Check battery capacity: Most newer smartphones and travel gadgets use power banks from at least 10,000 – 30,000 mAh, and they are usually under 100 Wh.
- Be accessible: For security screening, make sure you have the power banks in cabin luggage or in a personal bag.
- Know your limit: Most airlines permit up to 2 spare power banks above 100 Wh. For banks under 100 Wh, check your airline’s specific quantity policy.
- Label your gadgets: Some airports might ask for the battery capacity when going through screening.
- Use protective pouches: To minimize unintentional activation or short circuiting.

Airport Security Rules for Power Banks
Airport security officers may ask passengers to remove electronic devices from their bags during screening. In some cases, they may request that a device be powered on to confirm it is functioning normally. If you refuse to turn on a non-compliant power bank, Security may remove it, causing you delays during travel.
Cabin Luggage Electronics
Power Banks are categorized as portable electronics, just as other electronics are, and should be removed from other items, including liquids and laptops, for X-ray screening. Experts recommend:
- Carrying in a designated electronics pouch
- Separating cords and adapters to facilitate inspection
Airline Power Bank Capacity Limits
In general, TSA and IATA propose safety precautions; the airlines may have specific policies for battery capacity and the number of batteries permitted. These are important for providing safety standards for lithium batteries on airplanes. Scrutinize your airline’s policies before you leave so as not to encounter delays at security or have a battery/consumer electronics item confiscated by them.
| Airline | Max Power Bank Capacity | Max Quantity | Notes |
| Delta | 100 Wh | 2 | Over 100 Wh requires approval |
| Emirates | 160 Wh | 2 | Must declare at check-in |
| Ryanair | 100 Wh | 2 | Must be in carry-on |
Battery Safety Tips During Flights
Keep yourself safe while flying, and these tips for batteries may just help you:
- Some airlines restrict the use of power banks for charging during takeoff and landing. Check your carrier’s in-flight electronics policy before travel.
- Power banks should be checked periodically for swelling, damage, or overheating before travel.
- Any battery that overheats, smokes, or shows signs of damage should be reported to cabin crew immediately.
- Following these simple tips, you will be secure, air-legal, and able to enjoy a smooth flight.
Air Travel Safety and Lithium Battery Regulations
Lithium battery regulations for flights are established by international aviation safety organizations and airport security authorities. These rules are designed to reduce the risk of battery fires in aircraft cargo holds. Because cabin crew can respond quickly to battery incidents in the passenger cabin, spare lithium batteries such as power banks must remain in carry-on luggage.
Conclusion
Power banks are allowed on airplanes when packed in carry-on baggage and kept within airline battery capacity limits. The core rule is simple: carry-on only, never checked baggage. Knowing your power bank’s watt-hour rating before you travel is the most effective way to avoid issues at security. When in doubt, check directly with your airline.
FAQs
Can I put a power bank in my checked baggage?
No, TSA and IATA forbid checking power banks in checked bags in the interest of safety and fire hazards.
How many power banks am I allowed to bring on a plane?
Most airlines allow up to 2 spare power banks above 100 Wh. For power banks under 100 Wh, there is generally no strict quantity limit, though individual airline policies may apply. Always confirm with your carrier before travel.
What are the watt-hour limits for power banks on flights?
Under 100 Wh — Permitted in carry-on, no approval needed
100–160 Wh — Permitted in carry-on, airline approval typically required
Over 160 Wh — Not permitted on passenger aircraft
Do I need to declare my power bank at airport security?
Power banks should be placed in your carry-on and may need to be removed for X-ray screening, similar to laptops. Some airports or airlines may ask you to confirm the battery capacity. Having the capacity clearly labelled on the device or packaging helps avoid delays.
