CABIN BAGGAGE · LITHIUM BATTERIES
Power Banks on Planes: Air Canada, Air Transat and WestJet Rules
Power banks and spare lithium batteries belong in cabin baggage, not checked luggage. Capacity, airline approval and in-flight use rules still matter.
Understand watt-hours
| Capacity | General aviation rule |
|---|---|
| Under 100 Wh | Normally accepted in cabin baggage, subject to the airline policy. |
| 100–160 Wh | Airline approval is generally required and quantity is limited. |
| Over 160 Wh | Not accepted as an ordinary spare passenger battery; special rules may apply to mobility aids. |
If only milliamp-hours are shown, the usual calculation is Wh = volts × (mAh ÷ 1,000). A clear capacity label helps security staff verify the battery.
How to pack batteries
- Keep each spare battery in its original packaging or a separate pouch.
- Protect terminals with non-conductive tape when necessary.
- Keep batteries away from keys, coins and jewellery.
- Do not place a power bank in checked baggage.
- Keep it accessible rather than buried in the overhead compartment when the airline requires this.
Current airline rules
The operating carrier shown on your ticket controls the flight. Recheck its official restricted-items page before departure because charging and in-flight-use rules can change.
| Airline | Important power-bank rules |
|---|---|
| WestJet | Since March 19, 2026, only one power bank is allowed per passenger. It must remain on your person or in the seat pocket, not in checked baggage or the overhead bin. It cannot be recharged on board, and its use may be restricted when aircraft power is available. |
| Sunwing Vacations | Package flights departing since May 29, 2025 are operated by WestJet. Follow the WestJet policy and verify the operating carrier shown in your travel documents. |
| Air Canada | Spare batteries travel in cabin baggage. Air Canada lists up to 15 devices and 20 spare batteries, with no more than two batteries between 100 and 160 Wh and airport-agent approval required. |
| Air Transat | Lithium batteries for personal use travel in cabin baggage only. Up to 100 Wh, the published allowance is 15 devices and 20 spare batteries. From 101 to 160 Wh, prior approval is required and the total is limited to two eligible items. |
Documents and Cuba preparation
Keep your passport details, flight confirmation, insurance, accommodation address, eVisa information and D’Viajeros QR code available offline. A power bank supports the plan, but paper copies remain useful during outages or a damaged phone.
