KFD DC Adapter for Inogen Rove 6 Inogen One G5 BA-501 MANGO120S-24CB-ING Oxygo Next Oxygen Concentrator Car Charger BA-503 BA-500 BA-516 24V 5A 120W DC Converter 12V-24V Vehicle Power Supply Cord

I used this power supply with a "Duttek 5.5 x 2.1 mm Female to 4 Pin Mini Din Male" adapter to power my Luna II CPAP. Note: For those looking for other information on this, it's a 5.5mmx2.1mm tip with a positive center polarity. I took a guess that it was, as that's standard, and it paid off for me, but now I can confirm it for you!

The Inogen one G2 requires an output of 19v. The advertisement said it would work on the G2 and the picture showed the output of 19v. The one received was 24v. Unit would not work with it. Had to return it to the seller.

I've never seen a power supply arrive so well-protected for shipping. It even had peel-off plastic for its enclosure. Nice. Anyway, in my testing, the input voltage was at 14.4 volts, and the output voltage was 24.2 volts. Its 5 amp output should be enough to power any 24-volt device that uses a 5mm plug. Would recommend.

I needed an additional car charger for my Inogen G5 and this one fit the bill. It actually charges the unit faster than the original charger I received with the concentrator. Great price, great product.

I think I packed the car charger for my Inogen so I had to get a replacement or lets say extra one. Depending on the liter flow I may have to charge my portable oxygen device during a car ride. This is supposed to be compatible to my portable unit. Will update once I use it. UPDATE - used it yesterday and it works really well with my Inogen, It was charging as I was using it driving down the road.
