Power banks on flights: what is allowed and how to avoid screening trouble

Why power banks have their own rules

A portable charger is a lithium battery. Because of thermal risk, aviation authorities and airlines treat it differently from a wall charger or a cable.

The main rule: carry-on only

Most airlines forbid power banks in checked baggage: in the cabin an incident can be handled immediately, in the hold it cannot.

• Move the power bank into your carry-on before you leave home
• One forgotten in a checked bag can delay you at screening
• Follow crew instructions about charging during takeoff and landing

Capacity limits

Limits are expressed in watt-hours, not mAh, and the rating is usually printed on the casing. Above one threshold airlines require approval; above a higher one they refuse carriage.

Policies vary by carrier and country, so check your airline's baggage page.

The alternative: do not carry one

If you only need battery on the travel day itself, rent a power bank from a station and return it before heading to the airport. Dead Batt rentals start with a card tap: 15₪ for the first hour, a 30₪ daily cap and a 70₪ deposit released after return at any station in the network.

Summary

Power banks can fly, but only in the cabin and within the airline's capacity limits. And if you would rather not carry one, renting for the travel day is simpler.
