Tech checklist: essential gadgets for the plane

Power and adapters

The IATA reference threshold for transport without prior authorization is 100 Wh, equivalent to approximately 27,000 mAh for a standard battery; between 100 and 160 Wh transport is allowed only with airline consent, while beyond 160 Wh it is always prohibited. In general, each passenger can carry a maximum of two, always in the cabin — never in checked luggage — and some airlines, such as Lufthansa Group from January 15, 2026, have introduced further restrictions on use and charging on board: it's worth checking your specific airline's policy before departure. A universal travel adapter with multiple USB ports remains useful for powering multiple devices in hotels or lounges.

Audio and entertainment

Headphones with active noise cancellation (ANC) significantly reduce the background noise of engines, making it easier to rest or concentrate on long flights. A Bluetooth transmitter for aircraft, a small dongle that connects to the seat jack, allows you to use wireless headphones with the on-board entertainment system without having to use a wired cable.

Cable organization

An extra-long charging cable gives more freedom of movement when the outlet is far from the seat, while a pre-loaded e-reader guarantees light entertainment without draining your phone's battery. Keeping these items in a dedicated case prevents tangling and allows you to retrieve everything within seconds at security or during the flight.

Before each departure it is worth checking on your airline's website for updated rules on power banks and electronic devices: they change often, and what was allowed a year ago may not be allowed anymore.
