As of 2025, airlines around the world have tightened their regulations on carrying power banks during flights. These changes follow a rise in battery-related incidents onboard, prompting aviation authorities to enforce stricter safety protocols. Whether you’re a frequent flyer or traveling occasionally, knowing the latest power bank rules can save you time, stress, and even the risk of having your device confiscated at the gate.
Why the Regulations Changed in 2025
Lithium-ion batteries, the type used in most power banks, are powerful and compact—but they also carry fire risks if damaged, poorly manufactured, or improperly stored. In response to safety concerns, global aviation regulators such as the FAA, EASA, and ICAO have standardized rules for carrying battery-powered devices on flights. These updates include limits on battery capacity, quantity, labeling, and in-flight usage.
Are Power Banks Allowed on Planes in 2025?
Yes, power banks are permitted on planes, but only in your carry-on baggage. They are strictly prohibited in checked luggage, regardless of size or brand. This is a non-negotiable rule enforced by nearly all airlines worldwide.
Understanding Watt-Hour (Wh) Ratings
Airlines regulate power banks by watt-hour (Wh) capacity, not just milliamp-hours (mAh). If your device only shows mAh, you can calculate Wh using this formula:
Wh = (mAh × Voltage) ÷ 1000
Most power banks use a nominal voltage of 3.7V. Here are some common examples:
| Capacity (mAh) | Voltage (V) | Watt-Hour (Wh) |
|---|---|---|
| 5000 | 3.7 | 18.5 |
| 10000 | 3.7 | 37 |
| 20000 | 3.7 | 74 |
Ensure the power bank's Wh or mAh rating is clearly labeled. Devices without this information may be rejected during security screening.
Airline Power Bank Regulations by Capacity
Different Wh levels fall under specific categories of approval and restrictions:
| Watt-Hour (Wh) Range | Allowed on Plane? | Airline Approval Needed? | Quantity Limit |
|---|---|---|---|
| Under 100 Wh | ✅ Yes, in carry-on | ❌ No | Usually 3–5 |
| 100–160 Wh | ✅ Yes, in carry-on | ✅ Yes, prior request | Max 2 units |
| Over 160 Wh | ❌ Not allowed on the plane | ❌ Not allowed | 0 |
Quantity Limits: How Many Can You Bring?
While policies may vary by airline, the general guideline is:
Under 100 Wh: Most airlines allow up to 5 units per passenger.
100–160 Wh: Limited to 2 units, with prior airline approval.
Above 160 Wh: Prohibited on all commercial flights.
Always verify with your airline before flying, especially for international routes.
Can You Use Power Banks During a Flight?
In 2025, airline policies on in-flight power bank use differ widely:
Some prohibit any power bank usage once onboard.
Others allow it only if the device is in plain sight (not inside a bag or seat pocket).
A few permit usage only when the power bank is stored under the seat, not in the overhead bin.
Best practice: Use power banks only when you’re awake and monitoring them, and never leave a device charging unattended, especially on long-haul flights.
Airport Security & Packing Guidelines
Follow these packing tips to stay compliant and avoid delays at security checkpoints:
Carry power banks in your hand luggage (not checked baggage).
Label must be clear: Wh or mAh rating should be printed on the device.
Avoid damaged units: Swollen or cracked batteries may be confiscated.
Use original packaging or a protective case to prevent terminal contact.
Keep the power bank accessible for quick inspection.

Frequently Asked Questions (FAQ)
Q1: Can I check in a power bank in my luggage?
A: No. Power banks must go in carry-on luggage. They are not allowed in checked bags under any circumstances.
Q2: What happens if my power bank exceeds 160Wh?
A: Power banks over 160Wh are prohibited on all commercial flights, even in carry-on baggage. They must be shipped separately as cargo under hazardous goods regulations.
Q3: What should I do if my power bank has no label?
A: Without visible labeling (Wh or mAh), security agents may confiscate the device. Choose power banks that clearly state battery capacity and provide documentation if needed.
Q4: Can I bring more than two power banks?
A: If they are all under 100Wh, most airlines allow multiple units. For 100–160Wh power banks, you’re limited to two, and you must have airline approval.
Q5: Can I use my power bank to charge during takeoff or landing?
A: No. Wait until the seatbelt sign is off and your airline has announced that electronic devices may be used.
Q6: What voltage do power banks usually use?
A: Internally, most lithium-ion power banks operate at 3.7V. USB outputs may deliver 5V, but the calculation for Wh is based on nominal battery voltage.
Q7: What certifications should I look for?
A: Look for products certified by CE, FCC, UL, or RoHS. These confirm compliance with electrical safety, emissions, and quality standards.
Conclusion
Keep your power bank under 100Wh to avoid issues at security or boarding.
Always pack it in your carry-on and make sure the label is visible.
Don’t charge devices when sleeping or during safety-critical moments of the flight.
Use trusted brands with certified batteries and clear specifications.
Check your airline’s rules in advance, especially if you fly internationally.
