Exactly what I wanted
This is perfect for my use. I was able to get this through Amazon for less then half the price I would have paid if I had bought it through the Inogen website. And it is the very same item. Works great so far.

I don't travel without it
Yes, it's pricey, but I have found it indispensible. Also, I had one battery that quit charging in the O² concentrator but readily charged with this device and it's resumed it's place in the que.

Inogen - Nothing Works
Puchased in June 2025. Does not work, but nothing Inogen has does work. Problem ... Inogen is only game in town.
