Can you take Electric Scooters on a Plane?
The simple answer is yes for scooters with a battery size of less than 160Wh
The FAA rules state that it only allows batteries of 100Wh as carry on and checked in luggage and you can take up to two spare batteries with you.
With airline approval you are allowed to carry on a device with a 101 to a 160Wh battery, you must get prior approval thought!
Always check-in your e-scooter with the battery unmounted. No airline approves e-scooter transport with battery installed. Also, mention the battery size at check-in and make sure you read your transport company terms.
