In 2026, you may be traveling to Europe or elsewhere in the world (and you’re right to do so). But be careful about what you pack in your carry-on luggage . Since mid-January, some airlines have banned the use of external batteries during flights. The reason? If they are defective, they could cause a fire…
This item has been banned on planes for the entire duration of the flight since mid-January…
An essential item for travelers, external batteries are very handy when it comes to quickly recharging all our electronic devices. But since mid-January, this handy item has been banned on board for the entire duration of the flight. You will therefore have to make do with the sockets built into the seat to recharge your phone, camera, or computer… whether the flight is long or short.
In addition, a maximum of two batteries per passenger are allowed, with a maximum capacity of 100 Wh per device. Batteries with a higher capacity will require specific prior authorization. In all cases, batteries must be placed in a bag under your seat and turned off during the entire trip. Please note that batteries are not allowed in checked baggage.
Why is this prohibited?

The reason is simple: to avoid the worst-case scenario for an airline, fire! Certain external batteries (particularly those made of lithium-ion) can catch fire if they malfunction… This is far from an isolated case, as several similar incidents occurred last year…
Which airlines prohibit the use of external batteries?
Although this ban is not yet widespread, some airlines have already taken a decision on the matter. These include:
- Air France
- Swiss Airlines
Eurowings - Austrian Airlines
- Brussels Airlines
- Lufthansa
- Air Dolomiti
- Emirates
- Cathay Pacific
- China Airlines
- EVA Air
- Singapore Airlines
- Korean Air
- Thai Airways
This is a non-exhaustive list that is sure to grow throughout the year…
