Flying with the battery packUpdated an hour ago
Yes, but only in your carry-on. FAA rules don't allow spare lithium-ion batteries in checked bags. Detach the pack from the controller and keep it with you. Every iRESTORE battery pack is well under the 100 Wh carry-on limit (Essential/Professional 16 Wh, Elite 20 Wh). Check with your airline before an international flight.
