@curiouskitty You are welcome. I suspect much will depend on who is providing you with the oxygen. I would ask your provider how they can cover you when you are away from home. If they have a network that can provide you with the stable concentrator. And you should understand how Medicare covers oxygen. I just read that stable oxygen cocentrators are expected to have a five year life. Medicare pays your provider monthly claims for the first 3 years and then for the next two years, the provider is expected to leave the concentrator with you and still provide the necessary servicing (2Xyear) and tubing for the next two years. When the five years are up, you can change providers or continue with the same one and get a new concentrator and Medicare will start to pay them again . That is how I understand it. So it is important you have a capable provider that can cover you somewhere else if you travel.
I know someone in Florida who is 24x7 with O2. Florida electricity goes out often so she really has to plan, and during season if she goes out in her car she needs extra batteries in case she gets stuck in traffic. One learns to plan!
