Can I use the Caire Eclipse 5 concentrator on an airplane?

Yes, the Caire Eclipse 5 conforms to all applicable FAA requirements for portable oxygen carriage and use on board aircraft. Bring enough charged batteries with you to power your Caire Eclipse 5 for no less than 1.5 times the expected duration of your flight, ground time before and after the flight, security screenings, connections, and a conservative estimate for unanticipated delays. (Example: a 3-hour flight needs fully charged batteries with 4.5 hours of run time)
