How many spare POC batteries can I bring on a plane?

For batteries under 100 Wh (which covers most Inogen and OxyGo single and double batteries), the FAA sets no numerical limit—but you must be able to physically carry them. Use the 150% rule based on your total transit time to determine the exact number you need.

Can POC batteries go in checked luggage?

No. All spare lithium-ion batteries must be in your carry-on baggage. Only the battery currently installed in the device may be in checked luggage (inside the device). This rule is non-negotiable under FAA Advisory Circular AC 120-76E.
