This page combines a direct answer with airport, airline and primary-source rules. Safety answers are not influenced by partner content or advertising.
Short answer
From 27 March 2026 ICAO limits power banks to 2 per passenger and prohibits recharging them from aircraft power. Current IATA guidance allows power banks up to 100 Wh in carry-on baggage; power banks above 100 Wh are forbidden as passenger baggage. Never put a power bank in checked baggage.
Carry-on baggage
Spare lithium batteries and power banks belong in the cabin, not in checked baggage. Battery terminals should be protected against short circuit.
Checked baggage
Power banks and spare lithium batteries should not be placed in checked baggage. Devices with an installed battery can be subject to different rules.
Airport security
Check the Wh rating printed on the battery. Airlines may apply additional limits on quantity, capacity and in-flight use.
Check your departure airport
General rules are not always enough. Liquid limits and screening procedures can differ by airport, so check the airport you are actually flying from.

Power banks and batteries - three checks
For batteries, capacity is only one part of the answer; location in baggage and operator rules matter too.
- Check the Wh rating; if you only have mAh, use the PreflightMate calculator.
- Carry power banks and spare lithium batteries in the cabin and protect terminals from short circuit.
- Check airline-specific limits on quantity, use and charging on board.

Automation helps format, compare and translate data. A rule marked verified must be linked to an official source; conflicts and exceptions remain visible.
A specific airport, airline, route, destination-country rule or a security officer may apply a more restrictive requirement.
Example power-bank capacities
Using a typical 3.7 V cell voltage gives a quick Wh estimate. The manufacturer-printed Wh rating always takes priority.
