Hey 👋🏽. I use the QxgoNext. I’m on lev4 when I’m out it does get heavy. Still I prefer it to the tanks. Each time I left home (with an extra tank) getting in traffic stuck in traffic for hours and running out of oxygen. But with my oxgonext can changed n the car. U can order a backpack to use.

Hi Janine. Thank you! I have to carry those tanks around and they are definitely a pain! Remaining thankful - some oxygen is better than no oxygen🙂

I have the freestyle, its what the company i go through was able to get. Im only on 2 Ltd, the battery doesn't last as long as I'd like, only up to 4 hrs, but there is a care charger as well as wall charger for it and you can buy a bigger battery. Good luck.

I use a Inogen oxygen purse to go out with and a big concentrator hooked up to my CPAP at night. I am on level 3 on both. I don’t use the purse concentrator all the time, only when I am walking around the grocery store or when I exert myself.

Mine is an intogen One. It is like a purse. I use it to walk around. It only goes to 6 liters. It is battery operated. I also have one that is hooked up to my CPAP machine at night.
