Flying with a power bank: 2026 rules
A power bank does not go in checked baggage. The 2026 rules set clearer limits on quantity, cabin storage and charging during the flight.
Prepared by the FlyVentis editorial team and regularly reviewed for travel and event accuracy.
A power bank is a stand-alone energy source with a lithium battery and must travel in cabin baggage, not checked baggage. IATA's March 2026 update treats power banks separately from other spare batteries and sets a limit of two power banks per passenger for personal use. Check bag size and other electronics together with the carry-on baggage guide.
How the rules are applied can change with a stricter airline security policy. Check the operating carrier's condition; if more than one airline is involved, do not rely only on the selling company's baggage page.
Four basic rules when packing
- Put power banks only in cabin baggage; take them out first if the case will be gate-checked.
- Carry no more than two power banks per person.
- Keep each device in its own case or pouch and protect the terminals against short circuit.
- Do not travel with a device that is swollen, crushed, overheating or missing a readable label.
How to check the Wh rating
If the label shows watt-hours (Wh), use that figure. If it only shows mAh and voltage, you can estimate Wh = (mAh ÷ 1000) × V. The calculation does not replace the manufacturer label; security or the airline may ask for readable technical information.
| Energy rating | Practical approach |
|---|---|
| 100 Wh and below | Within the general passenger limit; still check the carrier's rule |
| 100–160 Wh | Under the 2026 transition, only with airline approval |
| Above 160 Wh | Do not assume it will be accepted as passenger baggage |
Do not use it or charge it during the flight
The 2026 IATA guidance prohibits charging a power bank on board and also advises against charging a phone or other device from a power bank. The carrier can make this a binding cabin rule. Keep the device where it will not slip between seats, remains visible and can be reached by crew if needed.
A small plan for gate-checked bags
- Keep power banks and spare batteries in an easy-to-reach pocket.
- If the cabin trolley is taken to the hold at the last minute, remove the batteries.
- Charge the phone from a wall outlet or a fixed charging point before the flight.
- Save a screenshot of the dangerous-goods notice in the airline's app.
