Battery rules

Type the capacity of your power bank or spare battery and see whether it can go in the cabin, needs the airline's approval, or cannot travel at all.

What you are carrying

What are they?
How is the capacity given?

Type the capacity printed on the battery (mAh) and the voltage of the cell (V). The watt-hours are worked out for you.

Power bank 1

The watt-hours are the capacity in mAh × the voltage in V ÷ 1000.

What you can carry

  • Power bank 1capacity not known yet

    Not enough information yet

    Add the mAh and volts, or the watt-hours printed on the label.

Fill in the capacity of every power bank to get the total for the trip.

Power banks stay in your hand luggage — never in checked baggage, where a fire is hard to control. Cover the terminals with tape or keep each one in a battery case.

Airlines can set their own stricter limits — several Asian airlines set lower limits than the FAA’s — so check with your airline before you fly.

The rules

  • 100 Wh or less: allowed in the cabin, no airline approval needed.
  • More than 100 Wh and up to 160 Wh: allowed only with the airline’s approval. Airlines usually allow at most 2 such batteries.
  • More than 160 Wh: not allowed in passenger baggage at all.
  • Power banks and spare batteries are hand luggage only — never in checked baggage.
  • A damaged, defective or recalled battery must not travel.
  • Cover the terminals with tape or keep the battery in a battery case.
