Planes can be diverted if passengers break the rule because the danger is so severe
The Civil Aviation Authority has issued a new warning as hundreds of people are packing batteries in their check-in luggage, creating a serious fire risk, and leading to planes being diverted. The CAAS says there were 650 incidents of batteries and electronic devices being packed in hold luggage last year – double the number of reports from 2024.
There were also more than 200 reports of batteries and electrical devices dangerously malfunctioning or catching fire on UK flights. The UK’s budget airlines permit power banks and batteries on board – with restrictions. The rules cover everything from power banks and spare batteries to tablets, vapes, phones, smartwatches, e-readers, and games.
Vietnam Airlines, Vietjet Air and Emirates have banned the batteries. Emirates states, like many airlines, the devices cannot be used during flight. In certain circumstances, they will be permitted on planes provided they are switched off and stored under your seat – not in the overhead cabin – with these rules coming into effect in October.
Electrical Safety First says lithium batteries pose a danger on planes because of their potential for “thermal runaway,” where the battery undergoes a rapid, uncontrollable rise in temperature, leading to fire, explosion, and the release of toxic fumes. Ryanair, easyJet and TUI all have regulations in place concerning power banks, batteries and electrical devices.
Ryanair
You may carry up to 15 personal electronic devices (this includes but not limited to: smartphones, tablets, laptops, cameras, handheld game consoles, headphones, power banks). Spare lithium batteries (including power banks) must be individually protected to prevent short circuits by placement in the original retail packaging or by otherwise insulating terminals by taping over exposed terminals or placing each battery in a separate plastic bag or protective pouch and carried in carry-on luggage only.
You may also carry up to 20 spare lithium batteries, provided they do not exceed 100Wh each.
Spare lithium batteries including power banks brought into the cabin should not be used to charge or power other portable electronic devices during taxi, take-off, or landing, not exceed 100Wh. They should not be placed in the cabin baggage loaded in the overhead storage locker. Be placed in cabin baggage under the seat in front, or on your person. Devices or batteries over 100Wh are not permitted in the cabin or the hold with the exception of Electric Wheelchair batteries.
Spare batteries, including power banks are not permitted in checked baggage.

easyJet
EasyJet strictly requires all lithium-ion batteries, spare batteries, and power banks to be carried in cabin hand luggage only, prohibited in hold luggage due to fire risks. Power banks under 100Wh (roughly 27,000mAh) are allowed without approval; items between 100-160Wh require airline approval. Batteries contained in portable electronic devices should be carried as carry-on baggage.
Should these items be packed in checked baggage, steps must be taken to prevent accidental activation and to safeguard the devices against damage; all devices must be completely switched off (not in sleep or hibernation mode). EasyJet imposes a limit of 15 portable electronic devices per passenger. Portable electronic devices containing non-spillable batteries must not exceed 12V or 100Wh, and passengers may carry no more than 2 spare batteries.
Where Smart Baggage is being brought into the cabin, the customer must be able to easily disconnect and remove the lithium battery / power bank, but it can remain in the bag. Smart baggage must not be accepted for travel if the lithium battery / power bank cannot be readily disconnected and removed by the customer. If smart luggage is to be checked in and placed in the hold, the lithium battery/power bank must be disconnected from the smart luggage at Bag Drop and taken into the cabin. Any exposed terminals should be protected from short circuit. The lithium battery/power bank needs to be disconnected, so if you are unable to remove it from your luggage, we won’t be able to accept the bag on board.

TUI
TUI’s regulations forbid passengers from carrying loose lithium batteries, power banks, or spare batteries in checked-in luggage. These items must be kept in hand luggage only. Power banks must generally not exceed 100Wh, and terminals must be shielded from short circuits. Devices should not be recharged while on board. Dry AA(A) batteries (type Alkaline, NiMh, NiC) for small personal items such as a pocket torch or a radio are permitted, provided they are inside the device or enclosed in sturdy packaging.
Where devices are stored in hold baggage, precautions must be taken to safeguard the device from damage and to prevent accidental activation; the device must also be completely switched off (not in sleep or hibernation mode). Loose batteries and power banks should be individually protected against short circuits by storing them in their original packaging, with terminals taped or placed in a plastic bag in hand luggage. Airline permission is always required for medical devices. For further details, see section Baggage – Medical baggage. TUI fly requires all power banks to be carried in hand luggage, never in checked baggage. They must be packed to prevent short circuits (original packaging or taped terminals). Generally, capacity is limited to 100 Watt-hours (Wh) per battery, with power banks not permitted to be used for charging devices or recharged onboard.
- Hand Luggage Only: Due to fire risk, all lithium-powered battery packs must be in the cabin. Capacity Limits: Power banks up to 100 Wh (roughly 27,000 mAh at 3.7V) are generally permitted.
- Safety Requirements: Terminals must be protected against short circuits, such as by taping them or keeping them in individual plastic bags.
- In-flight Usage: Power banks cannot be used to charge phones or laptops during flight, nor should they be recharged using aircraft power outlets.
- Storage: Keep them in your seat pocket or under your seat, not in overhead bins
