Quick answer: Yes, you can bring a power bank on a plane, but it must travel in your carry-on baggage—not in checked luggage. Battery size, quantity and onboard-use rules can vary by airline and country, so check your operating carrier before departure.
This guide was reviewed against current FAA, ICAO, IATA and CAAC guidance in August 2026. Airline and national requirements can be stricter and may change.
Can You Bring a Power Bank on a Plane?
Power banks are treated as spare lithium-ion batteries. In the United States, the Federal Aviation Administration requires them to be carried in the aircraft cabin. If your carry-on bag is checked at the gate or planeside, remove the power bank and keep it with you.
“TSA power bank rules” is a common way travelers search for this information, but the responsibilities are different: the FAA establishes U.S. aviation requirements for lithium batteries, TSA conducts security screening, and airlines may impose stricter conditions.
Review the FAA PackSafe lithium-battery guidance.
Can a Power Bank Go in Checked Luggage?
No. Power banks must not be packed in checked baggage. They need to remain accessible in the cabin so the crew can respond if a battery overheats, expands, smokes or catches fire.
If a power bank is discovered in checked luggage, the result can depend on the airport, airline and stage of screening. You may be asked to remove or repack it, and in some circumstances you may have to surrender it. Do not assume that it will automatically be returned.
Power Bank Watt-Hour Limits
Air-travel limits are based on watt-hours (Wh), not only milliampere-hours (mAh). The watt-hour rating represents the battery’s stored energy.
| Battery rating | General travel guidance |
|---|---|
| Up to 100Wh | Generally permitted in carry-on baggage. Airline quantity and onboard-use limits still apply. |
| Over 100Wh up to 160Wh | Under U.S. FAA rules, up to two larger spare batteries may be allowed with advance airline approval. International and airline rules may be stricter. |
| Over 160Wh | Generally not permitted on passenger aircraft. |
Always use the Wh rating printed on the product and confirm the policy of the airline operating each flight.
How to Convert mAh to Wh
If the watt-hour rating is not shown clearly, use the manufacturer’s nominal battery voltage:
Wh = (mAh × nominal voltage) ÷ 1,000
Do not assume every battery uses the same voltage. For example:
- PowerGo Slim 5,000mAh: 18.5Wh.
- PowerGo 10,000mAh: 10,000mAh × 3.85V ÷ 1,000 = 38.5Wh.
Both ratings are comfortably below the usual 100Wh carry-on threshold, but airline-specific quantity and onboard-use rules still apply.

How Many Power Banks Can You Bring on a Plane?
ICAO’s 2026 specifications limit passengers to two power banks. Airlines and national authorities may impose additional restrictions, so the safest practical approach is to carry no more than two and verify your airline’s policy before traveling.
U.S. FAA guidance separately states that most batteries for personal use do not have a general quantity limit, while allowing airlines to apply stricter limits. For itineraries involving multiple countries, follow the strictest applicable airline and national requirement.

Do You Need to Remove a Power Bank at TSA Security?
Screening procedures can vary by airport, equipment and officer instructions. Keep the power bank accessible in your carry-on and follow the directions given at the checkpoint. TSA may request additional inspection if an item cannot be identified clearly on the X-ray.
Can You Use a Power Bank During the Flight?
Do not assume onboard use is unrestricted. ICAO’s 2026 specifications prohibit passengers from recharging power banks during flight. Airlines may also restrict using a power bank to charge another device, where it may be stored, or whether it must remain visible and accessible.
Check the operating airline’s instructions and follow all crew directions. Rules may differ between airlines and routes.
International Power Bank Rules
International travelers should check every operating airline as well as destination and transit-country requirements. A rule that applies on a U.S. domestic flight may not be sufficient for another jurisdiction.
Domestic Flights Within China
Since June 28, 2025, China’s civil aviation authority has prohibited power banks without a clear CCC certification mark, with an unclear CCC mark, or from affected recalled models or batches on domestic flights within China.
How to Pack a Power Bank Safely
- Pack it in carry-on baggage only.
- Remove it if your carry-on bag is gate-checked.
- Protect exposed terminals from contact with metal objects.
- Use a protective case or pouch where practical.
- Do not travel with a swollen, damaged, leaking or recalled battery.
- Keep the Wh rating or product label readable.
- Tell the crew immediately if the battery becomes unusually hot, expands, smokes or burns.
The FAA recommends protecting terminals against short circuits and prohibits damaged or recalled batteries that could generate sparks or dangerous heat.
Choosing a Travel-Friendly Power Bank
For many travelers, a power bank below 100Wh provides a practical balance of capacity, portability and airline compatibility. A 10,000mAh model can provide approximately one full smartphone charge in typical real-world use, although the result depends on the phone, battery condition, charging method and conversion losses.
PowerGo 10,000mAh includes built-in USB-C and Lightning connectors, magnetic wireless charging and Apple Watch charging. Magnetic attachment requires a MagSafe-compatible iPhone, a phone with compatible magnetic alignment, or an appropriate magnetic case. Qi compatibility alone does not guarantee magnetic attachment.

Frequently Asked Questions
Can you bring a power bank on a plane?
Yes. Carry it in your carry-on baggage, protect it from damage and short circuits, and check your operating airline’s size, quantity and onboard-use requirements.
Can a power bank go in checked luggage?
No. Power banks are spare lithium batteries and must be removed from checked or gate-checked baggage.
How many power banks can I bring on a plane?
ICAO’s 2026 specifications limit passengers to two power banks. Airline and national requirements may be stricter, so verify the rules for your complete itinerary.
Is a 10,000mAh power bank allowed on a plane?
A typical 10,000mAh power bank is below 100Wh. PowerGo 10,000mAh is rated at 38.5Wh and is below the standard carry-on threshold. Airline-specific rules still apply.
Can I use a power bank during a flight?
Do not assume that you can. ICAO prohibits recharging the power bank during flight, and airlines may restrict using it to charge other devices. Follow the operating airline’s policy and crew instructions.
What happens if my carry-on is gate-checked?
Remove every power bank and other spare lithium battery before the bag is placed in the aircraft hold, and keep them with you in the cabin.
How do I determine the watt-hour rating?
Use the Wh number printed on the product. If necessary, calculate it using: Wh = (mAh × nominal voltage) ÷ 1,000.
Are the rules the same on every airline?
No. Aviation authorities establish baseline requirements, but airlines and countries may impose stricter rules. Check each operating carrier before departure.
