Air Canada Power Bank Limit 2026: mAh, Wh, WestJet & Transat

Verified August 28, 2026: Air Canada, WestJet and Air Transat all require spare lithium batteries and power banks to stay out of checked baggage. Airline-specific limits and in-flight rules still apply.

Air Canada recall alert: Air Canada currently lists Anker Power Bank A1647, Anker Zolo Power Bank A1681 and Anker Zolo Power Bank A1689 as prohibited on board because of a fire-hazard recall. Check your model number before travelling.

Air Canada, Air Transat and WestJet power bank rules at a glance

Air Canada: power banks and spare lithium-ion batteries belong in carry-on baggage. Batteries under 100 Wh are generally permitted; 100–160 Wh batteries require airport-agent approval, with no more than two spare batteries in that range.
Air Transat: lithium batteries for personal use belong in carry-on baggage. Up to 100 Wh is permitted under the published limits; 101–160 Wh requires prior approval and is limited to two eligible items.
WestJet: one power bank per passenger. It must stay on you or in the seat pocket—not in checked baggage or the overhead bin—and it cannot be recharged on board.

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.

Quick answer: carry power banks and spare lithium batteries in your cabin baggage. Remove them before a carry-on bag is gate-checked, protect exposed terminals and never travel with a swollen, damaged or recalled battery.

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.

Air Canada power bank limit in mAh

Air Canada publishes its battery limits in watt-hours (Wh), not one universal mAh number. For a common power bank rated at 3.7 V nominal, 100 Wh is about 27,000 mAh and 160 Wh is about 43,000 mAh. A typical 20,000 mAh power bank rated at 3.7 V is about 74 Wh. Always use the voltage and capacity printed on your own battery when calculating Wh, because a different voltage changes the mAh equivalent.

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.

Tell the crew immediately if a battery becomes hot, swells, smells unusual, smokes or is damaged during the flight.

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.
