Flying With an Electric Wheelchair: The 2026 Lithium Battery Rules

Flying with a power wheelchair is more common than ever — and more standardized. Almost every U.S. airline now follows the same FAA and IATA rules on lithium-ion mobility batteries. Here's what to know before you book.

Battery size limits

Lithium batteries up to 300 watt-hours (Wh) can travel in the aircraft cabin without airline pre-approval. Batteries between 300 and 600 Wh require approval but are routinely allowed. Most lightweight folding chairs use a 200–280 Wh battery — comfortably under the limit.

What to do at the airport

• Notify the airline at least 48 hours before your flight that you're traveling with a powered mobility device.
• Remove the battery before gate-checking the chair and bring it into the cabin in your carry-on.
• Tag the chair as 'gate-check' so it travels under the aircraft, not at baggage claim.
• Photograph the chair before handing it over — this protects you if it arrives damaged.

The document to carry

Bring a copy of your battery's spec sheet, ideally showing the Wh rating in plain English. Most manufacturers publish a one-page 'airline travel letter' on their support site — print it, fold it into the chair's storage bag, and hand it to the gate agent before they ask.

Damage and compensation

Under the Air Carrier Access Act, U.S. airlines must repair or replace a damaged wheelchair at fair market value, with no liability cap. Foreign carriers operate under the Montreal Convention, which does cap liability — keep that in mind on international itineraries.
