Cargador de fuente de alimentación adaptador de coche BA-306 12 V CC original OEM Inogen One 8'

This is an Inogen part number - we had an OxyGoNext and it worked fine (we bought 2 so we would have one for each car). This was overlooked when I sold the portable unit. I believe it will work on other Inogen models but not sure - be sure to research.
