As the summer travel season begins, Irish holidaymakers planning trips to the UK or further afield are being urged to double-check their luggage — and for good reason. A popular travel item has just been banned from checked baggage due to serious safety risks, and failure to comply could lead to confiscation or even airport fines.

The device in question? Portable power banks.

Used by millions of travellers to charge phones, tablets, and other electronics on the go, these small lithium battery devices are now under strict regulation by several aviation authorities, including the UK’s Civil Aviation Authority (CAA). Irish tourists flying into or out of the UK are especially advised to take heed of this change.

Why Are Power Banks Being Banned?

The ban affects power banks packed in checked luggage — not those carried in hand luggage. The reason is fire risk. Lithium-ion batteries have been linked to spontaneous combustion if damaged or exposed to certain conditions. Packed in the aircraft’s hold, where temperatures fluctuate and response time is limited, they can become deadly.

The CAA has updated its travel advice stating, “Portable chargers or power banks containing a lithium-ion battery must only be carried in hand luggage and are prohibited from checked-in baggage.”

Aviation safety analyst Martin Green explains, “These batteries can overheat, ignite, and cause fires that are extremely difficult to extinguish in a sealed cargo hold. That’s why airlines are being so aggressive about enforcing these bans.”

What Irish Travellers Need to Do

If you’re travelling this summer, particularly through UK airports or flying with European carriers, follow these essential rules:

• Power banks must be packed in your carry-on. They are completely prohibited in checked luggage.
• Check the watt-hour (Wh) rating. Devices over 100Wh often require airline approval and are sometimes banned entirely.
• Don’t use or charge power banks on the plane. Doing so is now against many airlines’ in-flight policies.
• Avoid unknown brands or poorly reviewed devices. Cheaper units can pose a higher risk of battery failure or combustion.

Travel tech expert Chloe Barnes warns, “The issue isn’t just that you might lose your power bank. These rules exist because the consequences of ignoring them could be catastrophic.”

Real Cases Have Sparked Tighter Enforcement

Airlines and regulators aren’t reacting to hypotheticals — they’re acting on real incidents. Several documented cases have shown power banks causing small onboard fires, requiring emergency landings and the deployment of fire extinguishers mid-air.

According to aviation risk consultant Darren Lacey, “One case involved a unit igniting during baggage loading, which delayed a flight by 6 hours and forced the evacuation of ground crew.”

It’s worth remembering: in the air, even a minor fire can escalate dangerously in seconds.

What Else Should You Watch For?

The travel warning doesn’t stop at power banks. There are broader safety recommendations all travellers should now follow when flying with electronics:

• Laptops, tablets, e-cigarettes, and external battery packs must also be carried in cabin bags.
• Spare batteries must be individually protected to prevent short-circuiting.
• Never wrap chargers in clothes or leave them exposed to moisture.
• Inform security if your device feels hot or behaves unusually.

Irish Tourists Targeted for Extra Scrutiny?

With UK-Ireland travel ramping up for summer, airport security teams at both ends are expected to increase enforcement. Some travellers have already taken to social media describing power banks being seized during random bag checks — particularly at London Stansted, Heathrow, and Manchester.

An Irish passenger recently wrote, “I had no idea this was even a rule. My power bank was taken at security, no questions asked.”

This lack of public awareness is a growing concern. Many travellers assume that because power banks are widely sold in airports and duty-free shops, they must be safe — but that’s not always the case.
