generators

Have you considered something like one of these;

I have the Delta 1300 and it's been great.

Have you considered using the money you would spend on a generator and putting it into solar and battery setup.

My Cpap machine from 12 years ago was able to run on 12V. They use very little power and can easily run from 12V either directly or via a small inverter.

It WILL BE a 4 stroke, no one uses a 2 stroke today!
People know what you mean but it isn't a Cpat it is a CPAP, Continuous Positive Airway Pressure.
Perhaps you should explain why you think you need a generator, ie, when do you need to recharge a battery etc. You certainly aren't going to run the generator all night while sleeping, so the recharging of the power source becomes the issue. Most, if travelling, the engine alternator recharges the battery and then used at night. Usually an auxiliary battery so engine still starts. You will need that second battery setup. Inverter if 240v required OR no inverter and use a 12V CPAP unit.
If you let people know what you intend, then more accurate responses tailored to your needs will happen.

Is Solar panel, regulator and aux battery an option for you? that way an inverter for 240v can be used to run the CPAP, or 12v direct.
Small Generator, must use a dedicated charger, ie, 240ac charger to smart charge the battery so it uses a %age of the generator output of 240v ac energy to recharge the battery in relatively short time.
If needed, unfortunately, Many people see generators have an 8 amp 12v output and decide that is what a generator does. "useless", and if trying to use that method, the cows will be in for milking long before the battery is charged with the engine running at MAX instead of slower, quieter more efficient option above.

Gear needed - CPAP, Battery, inverter or if 12v CPAP no inverter. + Recharging method of some sort.
A bit to get the head around initially!

A bit more info please.

What are you travelling in?
How much battery power do you have, e.g., Amp Hours
How are your batteries charged?
Is your CPAP unit a 12 volt machine?

Hi Paul,
I had not seen the Ecoflow before. I am impressed. It provides convenient power for those who do not wish to install a heap of gear into their vehicle or need to regularly change vehicles. Sure, it may be little dearer but is versatile and portable. Looks to be a well engineered product.
Way to go for some.

If Chris is considering a "power station" he should also look at LFP options - safer and arguably "better" (warranty, longevity) than lithium ion. Haven't looked at all the specs or models but these are an example of the type:
ArkPak Battery Box
Itechworld power station

Googling 'Lithium power stations' or similar will turn up a range of products +/- batteries.
Some have inverters and built in chargers but basic models also exist if you have your own 240V LFP charger and don't require an inverter.

Can someone explain how the capacity of the river at 288Wh (28.8v) converts to amphours.

Also what does "Because the AC outlets of the device are in a double blade, ungrounded configuration, it is recommended to use the UPS function of the device for temporary emergency use only. " and "DO NOT use electric devices with bare metal when charging" mean?

Hi Chris, get either the Yamaha EF1000is or the Honda EU1000i and you won't go wrong. The cheaper knock off brands can be a bit hit and miss.

Hi chris a,
Why not try a different approach?

I've been using a CPAP machine, while camping, for over 20 years. I've never used a generator, my source of power is to run the CPAP of an inverter connected to my axillary battery. It then gets charged up while driving during the day. If I'm static camping I use solar panels on the roof and bonnet of my vehicle.

Chris A,

I don't know what your set-up is, you haven't told us, so this just a first cut at comment.

With other campers in mind, I think the best option is a second battery that gets charged by the vehicle's alternator while you drive - there are a number of options for that - supplemented by a sensible amount of solar and a decent regulator for when you're camped up. The amount of solar depends on the total load on the battery, but somewhere between 100 and 200 watts is likely enough for small loads.

I would consider a generator as a last option simply because they annoy other campers. But if you have to do it get a quiet one from a reputable brand. If you go this route you will need a 240V mains battery charger. There are many, but Ctek is a good brand.

A Honda EU10i would be a suitable generator. It will happily run a 20 amp mains charger. (More if the charger is efficient, but that's a different discussion). Run it in Eco mode to keep the RPM and therefore the noise at a minimum.

If you want clean reliable quiet power this is what you need along with a nice LIfEPo4 battery.
But even the poster with starry eyes about the glorified battery solution will gulp at the price.

So after all the P- ing contests, what is the recommended device?
I need an aux battery of about 50AH , with a charging set up (DC-DC and solar) without an inverter.
Would this Itechworld device be suitable?

Hi Chris,

Having read all the other responses, I think you will find it difficult to find a generator that will run all night on one tank of fuel. Secondly, running a generator all night close to other campers is perhaps not quite the “right thing” to do, even if it is a life saving device. You may find you will need to indicate your need to run a generator all night owing to a medical condition by placing signage around your van.

Perhaps unknowingly you have bought the wrong CPAP machine, as there are models out there that can run on 12 volt power supply.

I feel for your predicament, and I think that if you want to camp off grid and still use a CPAP machine, that you buy a 12 volt machine, and perhaps sell your other one to recoup some of your initial outlay..

Macca.

I have a Westinghouse 2400 generator they probably do smaller sizes but mines been great no problems at all we use it when we loose power in the tropics during cyclone season. It's as quiet as my neighbors Yamaha I have a switch installed at the meter box so I can run lights tv and a bedroom A/C when needed. I would highly recommend them.

Choose your CPAP machine wisely & the need for a generator disappears.

We have no generator & rely soley on 'old fashioned' solar & batteries (ie. we use AGM batteries),

The key is to use appliances which are frugal on power. My Cpap averages around 20Ah per night, or 26Ah per night using the humidifier. This is 'peanuts'. This is as much as 2/3rds less power consumed compared to the CPAP machine brand leader with it's heated hose humidification.

Sadly the manufacturer of my machine is ceasing production of CPAP's at the end of the year, to concentrate on oxygen machines in these Covid times ....... so I have just bought another as an eventual replacement whilst they are still available because there is nothing else comparable on the market. They will continue to supply spares if needed. My Devilbiss Intellipap 2/ Devilbiss Blue has been used nightly for the past 5 years most of which have been in an off road camper, so it has handled plenty of dust & corrugations, & currently shows no sign of fatigue. There are a few still available in Australia for around $1300 (Google Devilbiss Blue). Quiet as Resmed . Utilise *native* 12v, & pulse dose humidifcation, both of which significantly reduce power consumption on an otherwise conventionally humidified machine. Footprint around the same as a 2 litre ice cream tub. This Link is where I bought my second one from a couple of weeks ago.
