CPAP Battery for Flight to China on Delta?

Yes, you can and should plug your ResMed AirSense 11 into the aircraft's power outlet, as this is the primary and most reliable method for in-flight use. Under 38 CFR 1.1, the VA is authorized to provide "prosthetic appliances," which the VA's Adjudication Manual M21-1, V.iii.1.A.1.b interprets to include devices and accessories necessary for the effective use of an issued appliance, like a CPAP. However, the VA typically provides a CPAP machine and standard accessories for home use; a battery for international travel is not a standard issue and requires a specific prescription and justification from your VA sleep physician demonstrating medical necessity for mobility (see 38 CFR 17.3230). To pursue this, your actionable next step is to contact your VA sleep clinic or Prosthetics and Sensory Aids Service (PSAS) to request a travel battery, submitting a clinical note from your provider detailing the need for continuous therapy during your long-haul flight. If the VA cannot provide one, commercially recommended options compatible with the AirSense 11 (which uses 24V DC) include the Medistrom Pilot-24 Lite or the ResMed Power Station II, both designed for aviation use—always confirm with the airline (Delta) regarding their specific power seat requirements and policies in advance. *Disclaimer: This information is for educational purposes regarding VA benefits and procedures only and does not constitute legal, medical, or official VA advice.*
