Can I bring a power bank on planes now?

The recent incident of an onboard power bank fire that delayed an Alaska Airlines flight has triggered renewed scrutiny and swift policy changes from carriers and regulators. That event — a reported power‑bank fire aboard a Wichita–Seattle flight — prompted airlines and authorities to tighten rules, and at least one national regulator has moved to ban the device's use on certain services.

How regulators and airlines are responding Japan has announced plans to ban power‑bank use on flights this spring amid fire‑safety concerns, and several carriers around the world have already introduced stricter rules or outright bans. Airlines now vary widely: some allow power banks only in carry‑on baggage, others require devices to meet specific packaging or capacity rules, and a few prohibit them entirely on some routes.

Practical guidance for travelers - Check airline rules before you fly: carrier policies now differ and can change quickly after safety incidents.
- Keep power banks in carry‑on, unless your airline explicitly permits checked carriage (many do not).
- Avoid damaged or swollen batteries and do not use or charge a suspect device during a flight if the carrier or crew prohibits it.
- If a country has announced a ban, assume enforcement on all inbound and domestic flights there.

Why it matters Lithium‑ion batteries can present a fire risk when damaged or improperly stored; regulators and airlines are prioritizing cabin safety. Travelers who rely on portable chargers should plan alternatives — extra battery‑powered devices, fully charged devices before departure, or approved in‑flight power outlets — and confirm current rules with their airline to avoid confiscation, delays or denied boarding.
