Short answer: Pack power banks in carry-on baggage only, bring no more than two, keep each at 100 Wh or less, protect terminals from short circuits, keep the Wh/mAh label readable, and do not recharge a power bank from aircraft power during flight.
Packing is where many travelers make battery mistakes. The first rule is simple: standalone power banks stay in cabin baggage, not checked luggage.
For 2026, quantity and in-flight charging matter too. Do not bring a third power bank as a backup, and do not plan to plug a power bank into aircraft USB or seat power.
Before leaving home, photograph the device label, save the manufacturer specification page, and run a route-specific check if your trip involves China, Thailand, Korea, an over-100Wh device, or a recalled model.

Run a packing checkFAQ
Should power banks go in a plastic bag?
A separate pouch or bag can help prevent short circuits. The key is that terminals are protected and the device remains in carry-on baggage.
Should I keep the power bank in the overhead bin?
Avoid hiding power banks where they are hard to access. Some guidance and airline policies prefer keeping them accessible rather than in overhead lockers.
What documents should I save before travel?
Save the manufacturer specification page, a photo of the device label, and any airline approval or certification evidence relevant to the route.
