Overview
- Major UK carriers now cap power banks in carry-on bags and bar in‑flight charging, with airline-specific limits on the number and size of spare lithium cells.
- British Airways permits two power banks in hand luggage and allows up to four spare lithium‑ion batteries under 100Wh, with 100–160Wh spares needing airline approval.
- Jet2 allows two power banks and up to 20 spare batteries under 100Wh, while Ryanair also permits up to 20 sub‑100Wh spares so long as they stay in carry‑on.
- EasyJet requires all spares and power banks to remain in cabin bags with a general 100Wh cap and approval for 100–160Wh, as Wizz Air limits spares to two and requires approval for larger cells.
- ICAO’s global rule now limits each traveler to two power banks and bans recharging on board, and filmmakers using sub‑100Wh cine batteries are still allowed but should carry spec sheets to avoid gate misclassification.
