Id be disappointed if the switching regulator injected enough noise to be a problem… but I have exactly 0 experience with those other devices so I wouldn’t guess.

P.s. The Cypress (really Spansion… actually Fujitsu) regulators don’t really make any sense … I was more talking about the Infineon ones…. But that area of electronics is mostly only theoretical for me.

I fried my 24V BKool portable A/C by running it from the accessory plug. I moved to two lithium motorcycle 12v batteries in series.

I am curious as to how well an O2 concentrator works at altitude where the partial pressure of O2 might be much lower than at the elevations these devices are designed to work at.

FAA has approved the use of O2 concentrators in airliners where the cabin pressure is typically 5000-8000 ft. I've had mine up to 9000 with no problems. Bernie
