Some background, my husband has been using supplemental oxygen 24/7 for a number of years. Where we live our electricity supple has been very stable, no outage for last few years. He also has an Inogen portable machine. We are thinking we have been fortunate with the electricity and foolish to not have a backup. What kind of generator is needed to run a home concentrator? It may sit for long periods without use. Thank you for your input.
I'm new here and this is my first post, if I make an error or two let me know. I'll paste a few links below to help you figure out what capacity generator to get. I've been researching this very subject as I have a concentrator and here in Georgia we lose power once or twice a year sometimes for days.
You have to have the generator outside when it's running because they make carbon monoxide gas (exhaust) and that's deadly. So you need to make sure that you can move it around, they can weigh anywhere from 40 to over a hundred pounds. I know you said you just want to run the concentrator but it might be nice want to run a few lights, TV, refrig? As you'll read there is very little cost increment going from a very low power to a medium power unit. I hope this helps you.
Here are the links I mentioned
A commercial site, they have a really good calculator to help you size a unit.
Home Depot, A great article that explains generatorolgy:
Hi senrab, and welcome! We appreciate you sharing your own personal experience when it comes to house generators with the community.
The links you provided are a terrific resource to assist in knowing more about generators. There are also neat guidelines and charts for aiding in the selection of the correct size generator for one's own specific home application.
I visited each link myself - it closely resembles the decision process I went through when we installed a whole house generator for our home.
Thanks so much for your input here.
Looking forward to your continued participation in our online community.
Wishing you well,

Here's my two cents. We live in area that is prone to power outages, sometimes up to 10 hrs. Years ago after moving here and our first power outage we bought a 7000 watt (I think) gas generator that will handle our fridge, freezer and tv, plus more. This one will run up to 8 hrs depending on what is plugged into it. So I know that it will handle my O2 concentrator. My generator is in a protected shed with lots of air flow, that is about 20 foot from the door. So all I have to do is start it, run an outdoor extension cord and I'm good.
I think for someone that is interested in just running their O2 concentrator. I suggest getting a 1000 watt generator. I think my concentrator runs on 350 watts. (my computer has a 600 watt power supply and the 1000 watt generator would handle it)
I hope this is helpful!
Hi jbyrd - thanks for joining in the conversation here. We appreciate you sharing your own personal experiences using a generator for the home. It sounds like you found the right capacity and configuration that works well for your set of circumstances.
We value your input.
All the best,

We have a generator that needs to be pushed from the garage to where the portable transfer switch outlet is outside the house if there is an outage. It would be too heavy for me, but my husband, and son know how to do this and start it. It works great. It was from Farm Fleet, and around $800.00 a few years ago. You need to start it up every so often, and change the oil. It uses a propane tank, that can be switched out after so many hours. Other options are gas. Portable transfer switches may need to be installed by an electrician, and attach to your electrical panel. My husband installed ours because he is in electrical manufacturing. I bought an Evergo, and Innova so that I can charge them as a back-up. I only need night-time oxygen at this point at 2L. They also can be charged in the car. I have an oxygen cylinder I got from Lincare about 10 years ago. It's in the basement, but they say it still works. Not sure, nobody's come to test it. It's kept the major appliances, sump pump, heat and air running for hours when needed. The portable transfer switches are sold to places like Home Depot, or electricians who do the installations. They can be a resource to help you determine what you need. In an emergency there must be public buildings that have the large generators. I would think you can research one, and maybe utilize their electricity to keep a portable unit charged.
Sam S. Thank you for your reply. I have contacted our utility because of information here on copd.net. Turns out in my city they only keep track of high risk households in case of shut off for non payment. It appears there are several things to consider when buying a generator.
