Have you considered something like one of these;

That is just a battery with some expensive stuff attached.
It still needs to be charged when it is flat.
Calling it anything else is a con job.

Paul.
"it has been great" Is it still great and how do you use it? that may help Chris. I presume yours needs charging and so, HOW?

I agree with Peter, Con Job. It may be high tech but is that what you really need? Maybe it never goes flat!
Those things ARE NOT generators, they are storers and release for use later.

Traveling, Camping, In the event of a power failure here at home (is that enough usage RMD)

Charges by 240 volt @1200 watts, solar or 12 volt cig socket 10 amps. So yes RMD it's been flat.

So lets recap a 1260 wh 18650 cell batteries (105 amp hr), inbuilt 1800 watt pure sine wave inverter, inbuilt 1200 watt charger, inbuilt 400 watt solar charge controller 10-65 volt 10 amp max. All together in a nice neat package that weighs 14kg and you can carry with one hand. Yes sure their expensive, are they over priced, most likely. Are they convenient, hell yes. Are they simple and idiot proof to use, yes. Are their cheaper options most likely, But put all those features together and the cost difference may surprise you in how little their is. Can most people put a system together similar to the above, NO even if they think they can. Can I, yes, Have I, yes. Would I again, no because these are such a neat little package, that works and, it works very very well.
Yes I have a petrol geni and agm batteries, but technology is changing and, changing fast.

Not quite the same Rod. Redarc's GoBlock, rather strangely, does not contain an inverter, so no 230vac.
Furthermore, it is $800 dearer than the Ecoflow Delta 1300.

No wonder that Redarc got into the battery business.... they sure know how to charge!

A "power station" generates electricity whether it be hydro, coal, or nuclear powered.
This is NOT a "power station" in any conventional interpretation of that term.

If the OP has plenty of money and does not want the noise of a ICE generator and does not want to go the solar route then this is an option. https://www.efoy.com/
I owned one for a couple of years. Now that was/is a "power station".

Some are impressed with the ecoflow features/claims. Yes high tech, but has big big charger, but also says it has a ciggy plug lead to charge the battery. WOW, with 5 amp ciggy charging away from the grid is indeed impressive and sloooow. It can handle solar too but most won't want or have big solar panels to do the job.
So, for Chris, who must have his head done in by now, has to decipher the mass of concepts and components. In his case, some vehicle charging on a suitable sized battery, add small easily carried solar and mppt reg to assist. Maybe a small generator and 240v charger of suitable size if off grid, constant clouds and no road travel. Basic and sufficient is waaaay cheeeeaper than the Eco thing which has to cost 3 times the price EVEN with the huge range of horrendous prices shown. Convenient yes but! All ok for the well heeled folk to push expensive over practical.

Peter, in what way is an ICE generator a "power plant" when this battery option is not? There is an input (potential output energy), in the case of the ICE, fuel. In the case of the battery, electrical charge. There is storage (in the case of the ICE a fuel tank, in the case of the battery a reversible chemical reaction). There is output. In both cases, electrical energy. For the ICE via chemical/physical conversion with significant by-products and energy losses (emissions, heat, noise). In the case of the battery, reversing the chemical process to output electrical energy, by-products are heat and some deterioration in chemical conversion efficiencies).

The other emissions for the battery are prior to input and determined by the source (240v ac, solar, etc.), whereas for the ICE they are determined by production, transport and handling of the fuel.

In both cases the initial "power plant" part of the equation is the production of the input for usage as potential energy (if that is how you choose to define it. And a choice it is, not a definitive statement). If you define it as a system for conversion of input potential to output (electrical energy) they are both in the same category. All in the definition (and, as Allan has pointed out, the marketing!)??

Cheers,

Mark

It can be recharged with solar;

Harness the power of the sun by connecting DELTA to three 160W solar panels to fully charge in just 3.5-7 hours. Alternatively, you can connect DELTA to four 110W solar panels to fully charge in 4-8 hours

That makes it's a power station.

No problem with a mixture.
It is simply a question of where the ENERGY (by virtue of its height) in the water came from.
If it came from electricity from wind or solar then the reservoir is a battery to store that energy so it can be turned back to electricity as it is needed.
In general terms, Snowy 1 is power stations.
Snowy 2 is batteries (energy storage) from water pumped using electrical energy that is excess to current needs from wind or solar.

Telling people someone is the "VOICE OF DOOM" is targeting the person. Anyone who does not agree with your well heeled life and viewpoint is ridiculed. You often denigrate people who aren't with your ideas usually with aloof comments. Money seems no object to you, others often cannot afford what you endorse. What I said to Paul is to get him to get him to explain, instead of simply posting something, ie, hit and run. Unfortunately, Paul decided to do similar. and unless getting his way will see us later it seems. ie, He is very short with Peter and taken his cricket bat home.
Chris is unsure of the basics let alone high tech expensive gear which may not be necessary. No one said it didn't work and it is an option. Hopefully Chris can absorb the concepts. If Chris is prepared for an overdraught at the bank and they are confident with the repayment profile, then ECO it is.

RMD,

I am so sorry if I have offended you. It was not intended as an insult to your person, merely to alleviate Paul's feelings. It was said as humour.
But really, you do seem to respond to so many threads in a manner that suggests that you are the only one with wisdom and we are all making a big mistake. Try using expressions like "I feel that" or "I believe" instead of "It is".

EDIT: I have just checked what I said about the EcoFlow, It was verbatim......
"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."
Where is my "well heeled life"? and "Money seeming no object..." ?
I also said that I was "impressed" with the product and that it was the "way to go for some".
Alleging that I have a "well heeled life" and that I "denigrate with aloof comments" is unacceptable and offensive. Many, in fact most of my recommendations are of simple and economic essence.
I have reconsidered... I retract my apology to you.

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.

Chris.
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!

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.

His absence from the thread and lack of detail in the question about his setup, his budget, and plans was noted Peter, but thanks for pointing out the obvious. Who knows whether he's thought his plan through or knows what options there are. Presumably he was after ideas from other CPAP-using travellers, otherwise he could have simply asked google.

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.

What!!! No wizz bang high tech gadgetry at all? Such a reliable system might be a bit cheaper too.

I thought, $3000 or so + CPAP + some power source to charge the high tech stuff which has relatively small power reserve/ run time to be not an option for Chris. Ok if he wants to/happy to start the vehicle halfway through the night.

Phil, Chris did not give the specs of his CPAP machine in his OP. If he has to use the humidifier on his machine then the average caravan solar system is not large enough to run it overnight. A generator may be a far more cost effective way to go than scrapping what he already has and putting in a half kilowatt solar array and lithium batteries.

Maybe we need to be discussing CPAP machines and their use with him to see what his power needs really are.

It is very compact, does not have a humidifier and uses B all power on 12v - roughly 0.5 amps (each machine).

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?

Following the normal rules of thumb for lithium and lead-acid batteries, your 50Ah lithium battery will give you about the same amount of useable power as an 80Ah lead acid battery.

Assuming that is sufficient and assuming the DC-DC/Solar charger is also an isolator (to protect the engine battery), then yes, the kit would appear to be suitable IMO.

Rod, you need a battery that has a greater capacity than your expected needs. 48 Ah is less than your needs. You did not say so, therefore I am assuming you also have a CPAP as the thread was commenced with CPAP needs.

If you are wholly reliant on your CPAP then I suggest you need a battery capacity for at least 3 days supply The fall back position is to have a caravan park you can rely upon to head for a powered site or be able to survive a night without your CPAP. Even in bad days of solar charging you do get some charging capacity, this will extend your stay without some external charging to somewhat more than your three day capacity. However, you need to be on your guard if you are wholly reliant on the CPAP.

The third line of defence is to carry a generator, as the OP was enquiring about.

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.

I'll second Cuppa's recommendation on the Devilbiss Intellipap II or Blue as its sold in Oz, I've actually had mine a bit longer than his and now have two after my older Phillips machine started getting a bit noisy and I bought a second Intellipap purely for use in the Oka when travelling.
Saves moving everything from bedroom to Oka every time we go away too.
As Cuppa said they run natively on 12v (as do Phillips machines and a few others) unlike Resmed machines which require a 12v to 24v converter which results in increased power consumption on 12v.
I nearly forgot to add that I use the standard humidifier every night and the Devilbiss is extremely frugal on the power use as well as being very quiet.
