Flying With a Power Bank? Airlines Let You Bring It – But Some Won’t Let You Use It

“`html

Power banks are something many people pack almost automatically for a flight, especially when they know they have a long travel day ahead. Our phones now hold boarding passes, reservations, maps and plenty of other things we may need while traveling, so running out of battery can quickly become a problem.

I always include a power bank among my carry-on essentials too. For a long time, the main rule I paid attention to was simple: keep it in cabin baggage, not in a checked suitcase.

Now there’s more to check before a flight.

Airline policies have changed quite a lot over the past couple of years, and international power bank rules changed again in 2026. You can be allowed to bring a power bank onto the plane and then find out that your airline doesn’t allow you to use it to charge your phone during the flight.

There’s another rule that’s easy to confuse with that one: charging the power bank itself. Plugging your phone into a power bank and plugging the power bank into the aircraft’s USB port or power outlet are two different situations under the current rules.

And airlines don’t all handle them the same way.

Can You Use a Power Bank on a Plane?

It depends on the airline.

There isn’t a worldwide ban on every passenger using a power bank to charge a phone during a flight.

Lufthansa Group airlines, Emirates, Singapore Airlines, easyJet, Jet2 and Qantas are among the carriers that currently prohibit passengers from using a power bank to charge another device onboard.

Other airlines still allow it. Their conditions vary: the power bank may have to stay visible and within reach, overhead-bin storage may be prohibited, or use may be restricted during taxi, takeoff and landing.

So the old advice – power banks belong in cabin baggage, not checked luggage – is still correct. It just isn’t the only rule worth checking anymore.

The Power Bank Rule Most Passengers Already Know

If you’ve flown with a portable charger before, you probably know that it shouldn’t go into your checked suitcase.

The U.S. Transportation Security Administration permits power banks in carry-on bags, but not in checked bags.

The Federal Aviation Administration treats power banks and portable chargers as spare lithium batteries and requires them to remain in the cabin as well.

A similar rule applies to smart luggage. If the suitcase has a removable battery and the bag has to travel in the hold, the battery comes out and stays with the passenger.

That part hasn’t changed. What has changed is what can happen after you board.

What Changed With Power Banks in 2026?

On March 27, 2026, the International Civil Aviation Organization announced new specifications for power banks carried by passengers.

One of the changes was a limit of two power banks per passenger. ICAO also prohibited passengers from recharging power banks during the flight. The announcement and the other changes are included in ICAO’s new power bank restrictions.

The distinction between the two types of charging is important.

Charging the power bank itself during the flight is prohibited under the new ICAO specifications.

So if you plug the power bank into the aircraft’s USB socket or seat power and the battery starts gaining charge, that falls under the restriction.

Now reverse the direction. You connect your phone to the power bank and use the battery you brought with you to charge the phone.

ICAO recommends against doing that too, but it didn’t introduce a universal ban that applies to every airline.

That leaves airlines free to impose stricter rules, and quite a few already have.

EASA advises passengers not to recharge power banks onboard and not to connect them to provide power to another device.

For passengers, the practical result is simple: the airline operating your flight now matters much more than it did when the only question was whether the power bank could go in your carry-on.

Some Airlines Let You Bring a Power Bank but Won’t Let You Use It

You can pack the power bank correctly, go through security with it and board with no problem. Then, a few hours later, your phone battery is running low and you discover that connecting the two devices isn’t allowed on that airline.

That situation is becoming more common.

The airline policies in this article were checked in August 2026. They can change, so I would still look at the carrier’s current rules shortly before flying.

The Lufthansa Group rules are among the stricter ones. Since January 15, 2026, passengers haven’t been allowed to use power banks to charge another device or to recharge the power bank onboard. They can’t be stored in overhead compartments either.

The rule applies across Lufthansa Group airlines, including Lufthansa, SWISS, Austrian Airlines, Brussels Airlines and Eurowings.

Emirates changed its rules on October 1, 2025. Passengers can still bring one qualifying power bank, but they can’t use it to charge another device and can’t recharge the power bank from the aircraft’s electrical supply.

Singapore Airlines introduced its no-use rule on April 1, 2025.

In Europe, easyJet says power banks can’t be used to charge other devices during the flight. Jet2 prohibits both charging the power bank and using it to power another device.

Qantas has prohibited using and charging power banks onboard since December 15, 2025.

Ryanair currently has a different policy. Ryanair allows passengers to use a power bank to charge a personal electronic device, except during taxi, takeoff and landing or when cabin crew instruct otherwise.

So I wouldn’t try to guess the rule from the airline’s country or region. Two airlines flying similar routes may have different policies.

Can You Charge Your Phone With a Power Bank on a Plane?

On some airlines, yes. On others, no.

This is the direction people usually mean when they say they want to “use” a power bank:

Power bank → phone

American Airlines currently permits it. Its portable charger rules say the power bank has to stay visible and within reach while it’s being used.

United also refers to passengers using portable chargers during a flight. Under its electronic-device policy, the charger should remain within reach, either on the passenger or in a personal item rather than in an overhead bin.

Delta allows use with additional restrictions. Delta says passengers shouldn’t use power banks to charge portable electronic devices during taxi, takeoff or landing, and the battery shouldn’t be stored overhead.

Lufthansa Group airlines, Emirates, Singapore Airlines, Qantas, easyJet and Jet2 currently take the stricter approach and don’t allow passengers to use a power bank to charge a phone during the flight.

If you tend to board with your phone at 12% because you planned to charge it later, this is a rule worth checking before you leave for the airport.

Can You Recharge the Power Bank From the Plane’s USB Port?

This part of the 2026 rules is clearer.

Don’t plan to plug your power bank into the aircraft’s USB socket or power outlet to recharge it during the flight.

The two directions look like this:

Aircraft USB or outlet → power bank: prohibited under the new ICAO specifications and also prohibited by many airline policies.

Power bank → phone: depends on the airline.

That distinction is worth remembering because “charging a power bank” can sound as though it refers to anything involving the device. Here, it means the power bank is the battery receiving charge.

Can You Take a Power Bank on a Plane?

For most passengers with an ordinary portable charger, yes.

Power banks haven’t been banned from aircraft. They have to meet the relevant battery limits and travel in the cabin.

Under U.S. FAA rules, lithium-ion power banks and portable chargers up to 100Wh are normally permitted in cabin baggage. Batteries from 101Wh to 160Wh require airline approval. Batteries above 160Wh aren’t allowed on passenger aircraft.

Those are general limits. Your airline can be stricter.

American Airlines and Emirates, for example, currently use a 100Wh maximum for standard permitted power banks.

For international trips, I always prefer checking what you can and can’t pack in your luggage rather than assuming that something accepted on one flight will be accepted everywhere.

Can You Put a Power Bank in Checked Luggage?

No. Keep it in your carry-on baggage.

This isn’t one of the new 2026 changes. Lithium power banks have been excluded from checked baggage for years.

There is, however, a situation where people can follow the rule when packing at home and still end up with the power bank heading toward the hold.

You arrive at the gate with the charger inside your cabin suitcase. The flight is full, overhead space runs out, or your bag has to be gate-checked.

Before handing the bag over, take the power bank out and keep it with you.

The FAA specifically requires spare lithium batteries to be removed from bags that are gate-checked or checked planeside. British Airways gives passengers the same instruction.

It’s one more thing to remember if you have a carry-on problem at the gate. Once the suitcase moves from the cabin to the hold, the battery inside it can’t go with it.

Can You Put a Power Bank in the Overhead Bin?

Depending on the airline, you may have to keep it much closer than that.

Lufthansa Group requires power banks to stay on the passenger, in the seat pocket or inside carry-on baggage under the seat.

Emirates prohibits overhead-bin storage too. American Airlines wants portable chargers kept somewhere they remain easily accessible.

Delta tells passengers to keep power banks in an accessible place such as the seatback pocket or under the seat. United says portable chargers should remain within reach, and British Airways requires them to be stored in the seat pocket or in a bag under the seat in front.

So when an airline says “carry-on only,” don’t automatically interpret that as “anywhere inside my cabin baggage.” A roller suitcase zipped shut above your head may not meet the airline’s storage rule.

How Many Power Banks Can You Take on a Plane?

The new ICAO specifications set a maximum of two power banks per passenger.

Some airlines allow fewer.

Southwest, for example, limits passengers to one power bank under its current lithium-battery policy. That rule started on April 20, 2026.

Emirates also permits one qualifying power bank.

American Airlines, Lufthansa Group, British Airways, Jet2 and Qantas currently allow two.

There’s an interesting difference for U.S. passengers here. The broader FAA guidance still says there’s no federal quantity limit for rechargeable batteries under 100Wh when they’re genuinely for personal use. Your airline can impose a lower number, and that’s why I would check the carrier rather than rely only on the general FAA allowance.

What Size Power Bank Can You Take on a Plane?

This is where the numbers printed on the charger become important.

Power banks are usually advertised as 10,000mAh, 20,000mAh, 30,000mAh and similar capacities. Airline rules, however, are commonly written in watt-hours (Wh).

Under general FAA rules, up to 100Wh normally fits within the standard allowance. From 101Wh to 160Wh, airline approval is required. Above 160Wh, the battery isn’t allowed on a passenger aircraft.

Your airline may stop at a lower limit.

Those figures use a typical 3.7V battery. What counts for your trip is the actual voltage and Wh rating on your own power bank.

The FAA calculation is:

Wh = volts × amp-hours

If the label gives capacity in milliamp-hours, divide the mAh number by 1,000 first.

American Airlines uses the same calculation in its passenger guidance and gives a 10,000mAh, 3.7V portable charger as an example. That works out to 37Wh.

Can You Bring a 20,000mAh Power Bank on a Plane?

A typical 20,000mAh power bank rated at 3.7V works out to about 74Wh, so it falls below the common 100Wh limit.

That takes care of the capacity question. You still have to check the airline’s limits for quantity, storage and onboard use.

In other words, a 20,000mAh power bank can be perfectly acceptable to carry onto the aircraft and still be something your airline won’t let you use once you’re seated.

What About a 30,000mAh Power Bank?

I would check the label before taking one to the airport.

At 3.7V, 30,000mAh is approximately 111Wh. Under general FAA rules, that puts it in the 101Wh-160Wh category, which requires airline approval.

And some airlines use 100Wh as their own maximum for power banks, even though broader aviation rules allow certain batteries up to 160Wh with approval.

If you carry a larger power bank because you charge a laptop or several devices, look at the Wh number at home. The airport is not where I’d want to start doing battery calculations.

Why Do Airlines Want Power Banks Within Reach?

There’s a safety reason behind the increasingly strict storage rules.

Lithium-ion batteries can overheat and, in some circumstances, enter thermal runaway. The FAA says battery problems can result from damage, overheating, overcharging, exposure to water, improper protection or manufacturing defects.

Cabin crew are trained to respond when a lithium battery starts causing trouble.

A power bank in a seat pocket or under the seat can be noticed and reached quickly. One buried inside a closed roller bag in the overhead compartment is much harder to get to.

The FAA tells passengers to alert cabin crew immediately if a battery or electronic device starts overheating, swelling, smoking or burning.

That helps explain why several airlines now care not only about which bag contains the battery, but also where that bag is during the flight.

Your Phone Is Now Part of the Trip

I think this is one reason the new rules can catch people out. A phone running out of battery during a flight or just before landing can create more problems now than it would have years ago.

Boarding passes, hotel reservations, train tickets, maps, banking apps, two-factor authentication, translation apps and contact details can all be on one device.

For important information, I like having a copy available offline where possible. That way a low battery or a poor internet connection doesn’t leave me trying to retrieve something essential at the worst moment.

I also check the power bank before leaving home. It should be charged, undamaged and have a readable capacity label.

And, like every charger, it can still get left behind. Portable chargers are among the travel items people often forget, especially when they’re plugged in somewhere shortly before departure.

What I Would Check Before Flying With a Power Bank Now

I wouldn’t try to memorize every airline policy. I would check these details for the flight I’m actually taking.

Capacity: Look at the Wh rating on the power bank, particularly if you use a larger model.

Number allowed: Two is common under the new ICAO specifications, but several airlines allow only one.

Your bag: Keep the power bank in cabin baggage. If that bag gets gate-checked, remove the battery first.

Where it can stay onboard: Some airlines want the power bank under the seat, in the seat pocket or otherwise within reach rather than in the overhead bin.

Whether you can use it: Check the airline’s current rule before assuming you can plug your phone into it during the flight.

Aircraft power: Don’t plan to recharge the power bank from the plane’s USB socket or power outlet.

I’d add these checks to a night-before-flight check, particularly now, while airline battery policies are changing so quickly.

Bringing a Power Bank and Using It Are Now Two Different Questions

You can still bring a qualifying power bank on most flights. It belongs in the cabin, not in your checked suitcase.

But once you board, the airline’s own rules come into play.

International aviation specifications now prohibit recharging the power bank during the flight. Several major airlines go further and also prohibit using the power bank to charge your phone, tablet or another device.

Other carriers still allow that.

Storage rules have changed too. The charger that once stayed forgotten inside a cabin bag may now have to remain under the seat, in a seat pocket or otherwise easy to reach.

So before your next flight, I’d check four things: how many power banks your airline allows, the maximum capacity, where you have to keep yours and whether you can actually use it onboard.

The rules may have changed since your last flight.

More Questions About Power Banks on Flights

Are power banks banned on planes in 2026?

No. Power banks haven’t been universally banned from planes. They generally have to travel in cabin baggage and meet the applicable battery-capacity rules. Some airlines now prohibit passengers from using them during the flight, even though passengers can still bring them onboard.

Can I use a portable charger on a plane?

Check your airline. American Airlines and some other carriers currently permit portable chargers to power phones under specific conditions, while Lufthansa Group carriers, Emirates, Singapore Airlines, easyJet, Jet2 and Qantas currently prohibit that use.

Can I charge my power bank using the USB socket on the plane?

No. ICAO’s March 2026 specifications prohibit passengers from recharging power banks during flights, and many airlines also explicitly ban plugging a power bank into onboard USB or seat power.

Can I take two power banks on a plane?

Two is now a common maximum and matches ICAO’s 2026 specifications, but your airline may allow fewer. Southwest and Emirates currently limit passengers to one qualifying power bank.

Can I bring a 10,000mAh power bank on a plane?

A typical 10,000mAh power bank rated at 3.7V is about 37Wh, well below the usual 100Wh threshold. You still need to follow your airline’s quantity, storage and onboard-use rules.

Can I bring a 20,000mAh power bank on a plane?

A typical 20,000mAh power bank rated at 3.7V is about 74Wh and normally falls within the standard 100Wh allowance. Check the actual Wh number printed on your charger and the rules of the airline operating your flight.

Can I bring a 30,000mAh power bank on a plane?

Possibly, but check before flying. At 3.7V, 30,000mAh is approximately 111Wh. Under general FAA rules, batteries from 101Wh to 160Wh require airline approval, and some airlines use a stricter 100Wh maximum for power banks.

Does a power bank have to show its capacity?

Travel with one whose capacity can be clearly identified. Several airlines require the battery information to be visible, and British Airways says a battery may not be accepted if its Wh rating isn’t shown or can’t be determined.

What happens if my carry-on bag is checked at the gate?

Take the power bank out before the bag goes into the hold and keep it with you in the cabin. The FAA requires spare lithium batteries to be removed from gate-checked bags.

Are magnetic phone battery packs and charging cases treated like power banks?

Generally, yes, when they contain a lithium battery and work as an external power source. FAA guidance includes portable chargers and cell-phone battery charging cases within its spare-lithium-battery rules.
