Power banks are becoming a no-go item on more flights and an expert has revealed why airlines are cracking down on the item. In recent years, a growing number of airlines have implemented restrictions or outright bans on carrying power banks during flights. What was once an essential travel accessory is now increasingly being scrutinised by air travel safety authorities.

Travel expert Colin Pearson has shared the reasons behind these bans, the risks associated with carrying power banks and what passengers should know to avoid complications when flying. Although they have become indispensable for many, these devices pose a hidden risk that has prompted airlines to re-evaluate their policies.

Pearson says: “The main issue with power banks is the lithium-ion batteries they contain, which, if damaged or faulty, can pose a fire hazard.

“A malfunctioning power bank can overheat, catch fire, or even explode, which is particularly dangerous in the confined space of an aircraft.”

Lithium-ion batteries are known to be volatile, and when they are exposed to high pressure or extreme temperatures, such as during a flight, the risks increase. As a result, the International Air Transport Association (IATA) has recommended that power banks be carried in carry-on luggage only and limited to specific watt-hour ratings to mitigate the risk of fire.

The airline industry’s heightened caution around power banks comes after several incidents of fires caused by malfunctioning batteries. While these incidents have been rare, they’ve been enough to spark widespread concern among airline safety experts.

Airlines such as Qantas and Emirates have recently introduced stricter rules regarding power bank transportation. While these policies may vary slightly from one airline to another, most have begun enforcing size limits or outright bans on larger capacity power banks.

“The key thing to remember is to always check the specific airline's policy before you fly,” said Pearson.

“If you're planning to bring a power bank, ensure it’s within the allowed watt-hour limit, which is usually between 100 and 300 watt-hours. Also, pack it in your carry-on, never in your checked luggage.”

Additionally, some airlines are now allowing power banks with a watt-hour rating of up to 300, but only if they are carried in the cabin and not in the hold.

Smaller devices (under 100 watt-hours) are generally not subject to restrictions, making them a safer bet for passengers who want to avoid complications.

For those carrying larger power banks, Pearson advises considering alternatives, such as charging the device before travel or seeking out airports that offer charging stations to avoid the risk altogether. The decision to restrict power banks on flights may seem like an inconvenience, but it’s a necessary precaution.

Ryanair

Ryanair passengers are allowed to carry portable power banks but with certain restrictions. Power banks must only be kept in hand luggage, not checked baggage, and have a capacity of 100 Wh or less, or up to 160 Wh with airline approval. It is advised that power banks are individually insulated and protected from damage in cabin bags.

Jet2

Jet2 has strict rules for portable power banks. According to the airline: “When carried by customers, lithium-ion batteries, lithium metal batteries, and power banks that do not clearly state the watt-hour rating or lithium metal content, or where the watt-hour rating cannot easily be otherwise ascertained, are forbidden”.

That said, each passenger is permitted to travel with a maximum of 20 spare/loose lithium batteries (including power banks) in their cabin baggage. However, each battery must be individually protected to prevent short circuiting.

easyJet

easyJet allows passengers to carry power banks in their carry-on baggage, but must be individually protected to prevent short circuits. There is also a limit of two power banks per passenger and power banks must also have a capacity of 100 Wh or less.

The airline’s power banks restrictions also apply to smart luggage in the cabin. For safety reasons, the airline states that lithium battery/power banks for smart luggage needs to be disconnected. If you are unable to disconnect your power bank, you will not be permitted to bring your luggage on board.

British Airways

British Airways is very clear in their regulations surrounding batteries and power banks. According to the airline’s website, batteries of up to 100Wh, including power banks, can only be carried in cabin luggage and must be insulated from contact with metal.

Passengers are permitted a maximum of two spare lithium-ion batteries of Watt-hour between 100-160. Any power bank built into smart luggage must be disconnected before being carried into the cabin.

TUI

Falling in line with other airlines, TUI permits powerbanks in the cabin but only if there are individually protected against short circuiting. This means they should either be carried in their original packaging, with terminals taped or in a plastic bag in hand luggage.
