Can I fly with
my battery?

Find your power bank to see how much energy it holds, in watt-hours (Wh), and whether airlines let it on the plane.

The rule
What airlines allow

The limit is on watt-hours (Wh), the energy a battery stores. It’s not the watts (W) printed big on many power banks, which only say how fast they charge.

• 0–100 WhAllowed in carry-on
• 100–160 WhAirline approval, 2 at most
• Over 160 WhNot allowed
• In checked bagsNot allowed
