Airline baggage update: Why your power bank could see you grounded

You might want to double-check that portable charger before you head to the terminal, as major carriers including Ryanair, easyJet, and TUI have clarified strict bans on where certain electrical items can be stowed. It isn't just about weight anymore; it's a safety gamble that could lead to your luggage being pulled from the flight entirely.

What We Know So Far

The core of the issue lies with lithium-ion batteries. While they power our modern lives, they are technically classified as dangerous goods in the aviation world due to their tendency to overheat or catch fire—a phenomenon known as thermal runaway. If a fire starts in the overhead locker, the crew can tackle it; if it starts in the cargo hold, it’s a much different story.

Ryanair has been particularly firm: power banks must be in your carry-on luggage. If you try to sneak one into your checked-in suitcase, you’re asking for trouble. The airline specifies that a maximum of two power banks per person is allowed, and they must stay with you in the cabin. What's more, you're strictly prohibited from actually using them to charge devices while the aircraft is in flight.

TUI and easyJet follow similar protocols, but the nuance is in the Watt-hour (Wh) rating. Most airlines draw the line at 100Wh. Anything above that usually requires prior approval from the airline, and anything over 160Wh is flat-out banned from passenger planes. It’s a bit of a minefield for the unprepared traveler, but the logic is sound: safety over convenience every single time.

Interestingly, some passengers have recently reported being asked to remove even small 'lipstick' style chargers from checked bags at the gate. This crackdown follows several high-profile incidents globally where battery fires in cargo holds caused emergency diversions. By keeping these items in the cabin, crews can monitor them and use specialist fire-containment bags if things go south.

What People Are Saying

Aviation safety experts are backing the move, noting that the risk is low but the consequences are catastrophic.

Lithium batteries are perfectly safe until they aren't. In the hold, a smouldering battery can go unnoticed until it's too late for the automated suppression systems to cope.

How This Affects You

For British holidaymakers heading to the Sun or a city break, this means a change in packing habits. Don't just toss your tech kit into the big suitcase that’s going under the plane. If security or ground staff find a power bank in your checked luggage, they are authorized to open your bag and remove it. In some cases, your bag might not even make it onto the flight, leaving you in Malaga with nothing but the clothes on your back.

Check the labels on your devices. If the rating has rubbed off, airport security may treat it as a high-capacity unit and confiscate it. It’s always best to carry the original packaging or a clear photo of the specs if the device is old. Better safe than sorry, as they say.

Thermal Runaway

A chain reaction where a battery cell's temperature rises rapidly, potentially leading to fire or explosion.

Watt-hour (Wh)

A unit of energy used to measure the capacity of a battery. Most airlines allow up to 100Wh without prior notice.

Coming Up

Expect more stringent checks at the 'bag drop' counters this summer. Airlines are reportedly updating their digital check-in prompts to include more explicit warnings about power banks. There is also ongoing discussion among international regulators about standardising these rules even further to avoid confusion between different carriers.

At a Glance

• Ryanair, easyJet, and TUI have strict rules regarding lithium batteries and power banks.
• All power banks must be carried in hand luggage, never in the hold.
• Using power banks to charge devices during the flight is prohibited on many carriers.
• Most devices must be under 100Wh capacity to be allowed on board.
• Failure to comply can result in luggage being delayed or items being confiscated.

FAQ

Can I put my power bank in my checked-in suitcase?

No. Power banks contain lithium batteries which are a fire risk. They must stay in your carry-on luggage so the crew can manage any issues.

What happens if I forget and leave it in my big bag?

Airport security may remove it without your knowledge, or your bag may be held back from the flight entirely for safety reasons.

Is there a limit on how many I can take?

Usually, yes. Ryanair, for example, limits passengers to two power banks in their hand luggage.

How do I know if my power bank is over the 100Wh limit?

Check the small print on the device. Most standard phone chargers are around 10-20Wh, but large laptop chargers might approach the limit.
