I am in the same boat as yourself and have given Winter nights a miss for some years now for the same reason as you, come November I am days only until March or April.

I have recently purchased an Allpowers 288w power station refurbished by manufacturer on ebay for £94 and it lasts me for 6 nights on my Dreamstation CPAP device and I managed to inflate my barrow wheel as well with it, I purchased it primarily for overnight stops in Hotels with no available power points on my way down through France as they look at you a little strangely humping a massive leisure battery into the Hotel.

Just reviving an old(ish) thread.

I too suffer from OSA and use CPAP. I personally use the Ridgemonkey power pack for mine with the 12V cigarette lighter - works well for me and I can get 4 nights on it no problem. I also have 4 Makita 18V batteries, and Ive built my own box with a 12V DC regulator and cigarette lighter socket - I can usually get 2 nights on each 5A 18V battery - so more than enough for a week in France. But, if you don't have those, then something like a 110a/h 12v leisure battery should last you a week - just use a cigarette lighter socket on a lead with crocodile clips.

Whatever you do, don't go using a 240v inverter in a bivvy - not only are they extremely inefficient (i.e. waste energy) they're extremely dangerous to use in a wet bivvy. Most CPAP machines are powered off a 12V DC power supply, its just a case of getting the lead - if you can get the connectors yourself they're easy to make, or just buy from the manufacturer if they supply them.

Avoid using the humidifiers too - they use too much power, unless of course you have a BFO leisure battery, then fill your boots. I just disconnect the humidifier, but most have the option to switch them off to save power from the battery.

Another option if you have the means is to buy a travel CPAP machine, just google them - there's plenty online.

Only issue is winter fishing. I haven't yet found a solution to this problem. It doesn't matter how warm you are in your sleeping bag, if your CPAP is pushing 16L/min of cold air through your nose into your lungs you're going to get cold from the inside out. I haven't fished for several years though winter for just that reason. In fact last weekend I tried again - new water so keen as - on the first night I managed to drift off but woke in agony, I can not begin to describe the pain in my nose as it felt like it was literally frozen from all the 3 degree outside air being pushed though it whilst I slept. I ended up not using it for a couple of nights and felt like absolute **** in the mornings and most of the day. Mind you I do have quite severe OSA - when I was first diagnosed they said I was getting no more than 6 mins sleep per night - my AHI is now well below 5 on CPAP - so that means on CPAP I'm fine.

Ive also tried several MAD (Mandibular Advancement Devices) - its like a gum shield but on your top and bottom teeth and they're fixed together and usually adjustable but they force your bottom jaw forwards, in theory to open up your airway, but you end up looking like bruce Forsyth and I couldn't get on with them, even expensive privately made ones. Ive also tried the surgical route (and I really don't recommend that - I'll spare you all the details but anyone considering it please do PM me)

So other than powering your CPAP - I just wondered what you do (other than not using it) in the winter - I haven't yet found an effective way of warming up the air the CPAP pushes into you - would be grateful to hear from anyone that's solved it ? powering an electric heater will probably be a non-starter as it'd need a huge battery or even a bank of batteries ....I was wondering about of one of those diesel heaters they use on campa vans - perhaps putting it in some other shelter away from my bivvy with some flexible ventilation ducting into a box I put the CPAP into - but I have no experience of those diesel heaters - other than watching YouTube videos - I was a little concerned they might be a bit noisy - but, then again, unlikely to be as noisy as me snoring and gasping for air without CPAP. Or even something that could be powered by a gas canister - although don't want to relight the gas powered heated blanket debate - but did wonder if there was some kind of safe small gas boiler that could heat a small radiator inside an insulated box to warm the air into the CPAP ?

I pick my machine up tomorrow, been waiting months for the appointment so hopefully all going well I'll be able to work out what adaptors etc I need, good to see some advice on what powerbanks etc guys are using, when I first found out I needed a machine I started to think maybe id have to change the fishing I do, to just maybe days and places that have 240v. Luckily that doesn't seem the case
The only downside is the initial outlay on the powerbanks etc but if I need them to carry on then so be it

Sounds like you want something that isnít going to die on you . EcoFlow River is where I ended up for longer trips . Coupled with a solar panel it does everything, phones , boat pump , even the electric outboard. Best buy for years.

Snoring is not the problem, stopping breathing is the problem therefore, I don't see that device being of any use at all.

I use a ResMed CPAP machine and got one of their portable batteries. Cost a fortune but it's small and light and gives me 2 short nights on the bank. I have also used a Jackery Explorer 240 when I need an extra night or 2.

Go for the large (77850) or medium (42150) RidgeMonkey one. Jay Cater uses these for his CPAP machine, as do a good number of others that I know. They come as standard with the 12V slot too.

I was diagnosed with severe sleep apnea 3 years ago, I was suffering from lack of Oxygen to the extent of waking up with bad headaches every morning. That drove me to get help.

Using the CPAP machine was life changing for me, within a few days no headaches and my energy levels returned. I was feeling so much better.

Took me a couple of month sto try it when fishing. I use a Resmed machine, Resmed require 24v so be aware that from a 12v battery you'll need an adapter to up the voltage and like every thing medical related the prices of kit are eyewatering.

For most trips, I use Tracer lithium 8ah battery which lasts couple of nights and is light weight. When I go to fishing abroad I take a second, bigger battery 12ah. BYTW, I do not use a humidifer, as it consumes a lot more power.

One tip, the first time I used the CPAP machine, I had a run in he middle of the night. And with out thinking lept out of my bivvy, forgetting I was wearing the mask. The ensuing chaos of me dragging the mask, tubing and machine out with me taught me a lesson, you do need to be better organised! Was funny afterwards.

Its not a big deal now that I am used to the machine and have a routine. I have used the CPAP for long trips, over two weeks in France and even when mahseer fishing in India.

Final tip, be careful and keep the machine dry.

I fully appreciate that and i am not taking it lightly, and open to any advice from anyone who suffers I'm all ears to find out how you get on with your fishing etc this is all new to myself and I'm just trying to get my head around it.
I haven't had any feedback of how many times I stop etc, I'm presuming that info will be given to me next month when I have the appointment to trail a machine, it's given me questions to ask and I was working on a best case of maybe being able to fish without it if the Drs says it's ok, I'm not being naive and think I already known what they will say, I'm just trying to be optimistic, if I need to get powerpacks or have to change my fishing to suit then so be it,
I'm fully with you I don't want to be that angler either who died on the bank through my own negligence and put someone in a position of finding me. Appreciate the feedback
