On oxygen !!

[john65]

I have been put on oxygen overnight and am wondering if I can succesfully run the oxygen maker on my 2000 watt (with 4000 watt surge) inverter which is powered by 2 series 27 deep cycle batteries. the oxygen maker is rated
4.8 amp and has a motor of some kind inside. I do have space to add 2 more batteries.
Any comments or input gratefully recieved.
Thanks John

Hello Johnnn,

Welcome to iRV2, we're really glad to have you here as a new member and are looking forward to reading your posts about your RVing experiences and adventures in Eastern Washington. You'll find a great bunch of folks on this site who are very knowledgeable of RVing, the rigs we use, and the places we go in them.

As you'll see, they're eager to help and share their knowledge and experiences with others.

Electrically, you should be able to run the oxygen maker on the 2000 watt inverter. Considering it's 4.8 amp rating, it'll be using about 576 watts of power. Having extra batteries available as a back up would be a good idea in case the two connected to the inverter run down and you still need oxygen.

I'll move your post out of the "FAQ/Website Technical Support/Suggestion Box" forum so it gets better exposure for additional responses.


Again, welcome to iRV2, we're glad you joined.

As Richard/Hitchhiker already pointed out, your 2000 watt inverter will handle the approx 600 watt draw.

What you need to consider for the batteries is the following ten-to-one rule-of-thumb:
<LI> 4.8 amps at 120-volts . equals . 48 amps at 12-volts

So each hour your oxygen concentrator is running, it will be drawing 48 amps from the battery/batteries.
Look at your battery to find the amp-hours rating, take half of that as the best-practices-for-long-battery-life number of amp-hours you should take out of it each night.

For example, if each of your two batteries is rated at 100 amp-hours, you have a total of 200 amp-hours rating (maximum) in your battery bank. Half of that is 100-amp hours - - or just over 2 hours of run time for your oxygen concentrator.

This may be a good time to examine the feasibility of switching to higher amp-hour rated batteries - - as many as you can fit.

Would it be more economical to buy a 1000W genset to power the 02 unit? No worries about depleted batteries, or maintaining a huge bank of them and accompanying weight.

Thank you Richard, David and Ray for your input, and for this WebSite it is great but it is a learning curve for me to negotiate arround it! I am somewhat computor chalenged, but love it anyway! Thanks Johnnn

Maybe, but many campgrounds will not allow generator use overnight. Even a quiet one like a Honda eu1000i.

Concider having portable oxygen bottles for emegencies or use at night.

hey john,
check out the 12volt military medical oxygen
i didnt look at the price though, im sure its alot

Johnn A lot to consider on O2 use in RV.. Many of the oxygen converters apparently need a pure sine wave inverter, need to check with your manufacturer..There are a number of small O2 converters on the market, fairly expensive but compact and run on 12vdc or internal battery. Many use a pulsed or demand type O2 delivery, which really extend their time of use but cannot be used at night because you may not inhale strong enough to trigger the O2 flow while asleep. There are 12 volt low power units that provide both constant flow and pulsed that you can find on the internet. "Eclipse" by Sequal is one I'm aware of.. Your O2 provider should be able to get you a suitable portable unit. The Open Roads forum has a discussion on O2 use that may help.

Johnnn,

It sounds like you are planning for boondocking, which we have not done, but we run two concentrators every day/night from campground or relative home sources. When we are on the road, we run the generator. Our two kids who are on O2 are each on 1-2 liters.

We also carry a supply of E tanks for when we leave the MH, and for power outages. We have installed a 12-tank rack in our cargo trailer and when need arises we carry a second 12-tank rack strapped down. So far it's satisfied our needs.

Oh, we also carry a doctor's prescription for refilling the tanks when needed, but with careful planning, we've only needed this once.

Thank you all, my oxygen provider is lending me a 12 volt system. Thanks for the input, John

Thank you folk, we apppreciate all your input and advice. We have been on the road forabout six weeks and have had an ongoing battle with our HughesNet internet system which we think we have now got beaten into submission!!!! By the way we set it up ourselves on a tripod, and we love it.
Regarding the O2 I got a 12/110v portable unit and put 4 golf cart batteries in th M/H to feed the system. For some reason it is not reliable on 12v but works quite well on the inverter???It is true the puff puff system does not work well at night, we will be home in a month or so and I intend to persue some of the other suggestions you all sent me.
We are presently camped at Imperial Dam just out of Yuma, and loving ita!!!
