Travelers around the world are being urged to take note of new safety regulations concerning lithium batteries as airports prepare for a surge in summer travel. Aviation authorities, including the UK Civil Aviation Authority (CAA), are emphasizing that power banks, vapes, and spare lithium batteries must be packed in cabin baggage rather than checked luggage. This is to ensure that any potential overheating, smoke, or fire can be quickly identified and addressed by the cabin crew. Alarmingly, incidents involving lithium battery malfunctions are now occurring approximately twice a week, prompting a need for stricter compliance with flight rules.
Research shows that reported cases of overheating or malfunctioning devices have soared by an astonishing 98% from 2024 to 2025, with occurrences involving lithium-powered devices in checked luggage up by 91%. On average, each traveler carries about four lithium-powered devices, with many still unaware of the risks associated with improper packing. A single incorrectly stored power bank can lead to baggage removal, delays, diversions, or even uncontrollable fires on board.

Lithium-ion batteries are common in various electronic devices such as smartphones, tablets, cameras, and laptops due to their ability to store substantial energy in compact units. However, issues like manufacturing defects, physical damage, crush incidents, and exposure to extreme heat can lead to a dangerous situation known as thermal runaway. During thermal runaway, a battery can rapidly overheat, potentially releasing smoke, toxic gases, or flames—creating serious risks if this occurs in an aircraft. While cabin crew is trained to handle such emergencies quickly in the passenger area, the situation becomes much more complicated if it happens in the cargo hold of the aircraft.
Because power banks are categorized as spare batteries and not just regular electronic devices, the regulations stipulate that passengers must carry them in hand luggage. It’s essential for travelers to ensure their batteries are not damaged, swollen, leaking, or hotter than normal to prevent any risks.
As of March 27, 2026, the International Civil Aviation Organization (ICAO) has implemented strengthened global guidelines regarding power banks. Passengers are now allowed to carry a maximum of two power banks, with the stipulation that these devices cannot be charged during the flight. All such items must be stored in carry-on baggage and adequately protected when not in use. Typically, batteries rated below 100 watt-hours don’t require airline approval, while those ranging between 100 to 160 watt-hours may need specific airline permissions.
It’s crucial to note that not every airline will impose the same rules. Although international regulations aim to standardize safety procedures, individual carriers can set stricter limitations around storage, capacity, quantity, and usage. For example, Emirates allows only one power bank under 100 watt-hours while banning its use during the flight, whereas Lufthansa permits two power banks but similarly prohibits their usage except in the case of medical equipment. Passengers should verify their airline’s specific policies ahead of time to avoid complications.
In response to the growing concerns over lithium battery risks, airlines worldwide are adjusting their storage policies. For instance, Singapore Airlines mandates that power banks remain in cabin baggage and out of overhead compartments, with strict prohibition on their usage during the flight. Qantas upholds similar restrictions, allowing only two power banks per passenger and banning their use altogether. It’s increasingly advised that travelers keep power banks and batteries in easily accessible locations to ensure they can be quickly checked by both themselves and the cabin crew if any issues arise.
Proper storage is key; travelers should avoid burying power banks within overstuffed bags or overhead compartments since quick access aids in detecting any signs of trouble.
Before heading to the airport, passengers should conduct a thorough battery check. Store power banks, spare batteries, and vapes in cabin baggage and make sure to cover terminals with tape or place them in protective pouches to prevent accidental contact. Ensure that all power banks display a clear capacity rating and remove from packing any devices that are damaged or swollen. Keeping devices readily accessible can significantly facilitate quicker responses in case of overheating.
Also, travelers should stay mindful of the risks involved with gate-checking. If oversized bags need to be transferred to the aircraft hold, it’s critical to remove power banks prior to handing the bag over to staff. Whenever possible, keep these items in a smaller bag under the seat to retain full control over them during the journey.
While these updated guidelines may introduce some inconvenience, they are essential for ensuring traveler safety and minimizing disruptions at airports. Non-compliance could result in the removal of a suitcase containing a prohibited device, causing delays that may ultimately compromise scheduled flights. Discovering a battery issue post-departure might lead to serious consequences, including emergency landings. Thus, adherence to power bank guidelines not only aids in fire prevention but also helps facilitate smooth operations at busy airports worldwide.
The message for travelers is straightforward: Always pack portable chargers in cabin baggage, keep them easily accessible, protect them from damage, and never assume that using these devices onboard is allowed without checking the specific airline’s rules. There’s an increasing need for passenger awareness concerning lithium battery safety as more connected devices take to the skies. It only takes a few minutes of thoughtful packing to prevent potential delays and other safety concerns on your journey.
