Well i tried using the Z2 loaner last with my full mask and not happy at all....the noise drove me nuts, its set to start at 4 and ramp up to 10 over 5min, its mostly the air rushing up the tube and to the lesser extent the fan speeding up and down on the unit, exhale etc. The machine itself supplying the air was great.

Ive just gone from a S9 Resmed as it came up 'motor life exceeded' (27xxxxhrs) to an Resmed Airsense Elite 10 - its a better machine so im thinking about using it off grid and trying to see if i can,

1/ see if Chad at antigravity can send a PS-45 down to New Zealand (bit doubtfull now as im finding no one able to ship any lithium overseas even from Australia) and figure a plug set up from 24v -12v , im not electrical minded btw.

2/ Go the Medisrtom 24 lite http://medistrom.com/products-pilot24-lite.html , dont know how many nights (without humid) it would last, need at least 2, theres a NZ supplier @NZ $595 phew...

The Z2 is supposed to be the quietest travel CPAP, i did use the Qtube with the in line humidex AND without either , tried it with and without the powershell .

Ill be taking it back on Monday and will chat to the clinic about these issues and see if my set up is ok or not.

I have an old XP-10 I can part with, the platic case "popped open". Not sure about shipping from the States. If you think you'd be interested do som edigging and tell me how to ship and cost. I will think of a dollar amount........

My test of the antigravity ps-45 for cpap was a huge success. It did 8 hours last night and its still at 75%!

Specs:

Resmed S9 @ 14 pressure, no humidifier
Resmed dc battery 90w power supply
Antigravity PS-45 battery @ 45,000mAh

This means the PS-45 will do 3 nights for me + phone recharges. The ps-45 weighs less than 3lbs. That is 1lb per night of sleep!
Any reason why you didnt just plug the S9 into the A/C out ?

I'm curious too. It appears you are using the PS-45 to charge the ResMed battery while running the CPAP off the ResMed battery. Seems kind of odd to me, but I don't know your set up.

We recently had a power outage at 4 am on Christmas Day. I woke up when the power went out since the CPAP stopped. I grabbed my Makita USB adapter and a charged 3Ah battery and went back to sleep w/o issues. I already demonstrated that it will power my Transcend mini at my fairly low setting for a full night plus, and can be charged off the bike while riding during the day. I won't use it like I did the Transcend P8 as a back up system, but it's handy for outages and what is now a rare camping trip, for me.

The resmed does not have a battery. It has a 12v dc to 24v dc converter.

Massive efficiency loss via unnecessary dc to ac back to dc 24v conversation loss.

This is a pure dc solution, it is far more efficient than any solution that goes dc - ac - dc.

Exactly how I power mine, DC to DC stepup from 12v to 24v. I have a pair of Battery Power Solutions C-100s (97.68wh) in a bag, with a 2 into 1 DC cable, those going into the stepup convertor that goes into the S9 (I can usually get three, 6 - 7 hour nights, pressure at 10, no humidifier). I recently picked up a 280wh Rockpals "solar generator" and a 100w panel to see just how long I can extend my trip by packing those into one of the panniers to use.

Nice.

Let us know how the solar works out! I have been very curious about potentially adding this also.

Having purchased a 2021 Super Tenere, the thought of camping came to mind as did the idea of how to bring a cpap along. The cost of one of those travel CPAP machines are just out of my range considering the limited amount of use it will get. I tested my old System One CPAP, stripped down to just give me air, no humidification and it used a total of 60W/h for the night. My current S10 with humidifier and heated hose ran about 460W/h! I'm trying the S10 with the humidifier and hose turned off tonight, but I'll still put some water in the humidifier chamber as it can't be removed and we'll see in the morning how much power it uses. The bugger with the Resmed CPAPs are that they run on 24v instead of 12v and so either two 12v batteries in series or a step up converter will be required.

The System One machine worked, but it's so noisy compared to the S10 that between the discomfort of no humidification keeps waking me up and the noise from the System One Keeps me awake after that.

I'm looking at possibly using this: https://www.jackery.com/products/explorer-500w-portable-power-station to power my cpap, but this all adds up to a lot of weight. If it looks like I can bring all this stuff, I might just use the 110v powerbrick instead of a 12v - 24v step up converter as they would be near the same size. Yes, it might be less efficient, but perhaps more reliable.

Alas, I have other issues requiring me to use a 4" thick mattress which takes up a lot of packing room, all by itself.

It sucks getting old, but whatchagonnado..... <sigh>

Well, after last night's check on power consumption with my current CPAP machine and the humidifier set to minimum heat, it consumed 20w per hour and based on that, I ordered the 500w Jackery unit which should provide me with 2 full nights of CPAP with level 1 humidification. I was feeling quite well this morning, just a slight dryness in the sinuses. I tossed the S10 on my scales and as it is not able to be taken apart it was weighed WITH the humidifier and it weighs pretty much the same as the old System One CPAP only, without it's removable humidifier. All this stuff will take up some room in the luggage, but it's not that bad, nor is it that heavy, though the Jackery is getting up there at around 13 lbs. I dread to think how heavy it would have been if it used gel cells instead of Lion. That Jackery will also charge all my electronic devices and with it's built in 500w inverter, can power anything that uses 500w or less, that would normally plug into a 120v socket. So.... my CPAP will run off the inverter with it's power brick instead of fooling around with a step up converter to get 24v and then having to figure out where to get what appears to be a proprietary plug that they used...

I just realised I have an error in my previous message. I wrote the S10 used 460W/h, which was incorrect. It used a total of 0.460KW/h for the entire night. That would be close to 60 watts per hour, not 460 watts!

I used the PS45 last night with my Airsense S10 Elite with Humidity at 4 just to see how long the batt would last - 6hrs it turned out, I just plugged it straight in on AC.
Mine is a CPAP , pressure starts at 5 then ramps to 13.

Its charging up now so will try again tomorrow night, next i will try Humidity at 1 and try again then without Humidity but with water in the chamber.

I just checked the details on the PS45. My S10 with humidity set to 1 and non heated hose should get just over 8 hours on that battery. While I found using the S10 with water in the tank but no heat wasn't enough, it was better than nothing. The humidity in the house is only around 30% as we are in the middle of winter here. During the summer, I have to run a de-humidifier to keep things down to 50% in which case I would suspect that a setting of 1 would be more than adequate. I'm not going for perfection, just reasonable comfort. And like you, I'll just use the inverter, but there is a performance hit from all that up and down converting. Jackery suggests that their AC outlet will have an efficiency of 85%. So my 500w battery will only put out 425w on the AC socket.

I found the S10 without heating of the humidifier used 10 watts per hour and with the humidifier set to 1 it used 20 watts per hour. If you managed to get 6 hours with the humidity set to 4, you should be easily able to get 8+ hours at a setting of 1 and if you are comfortable enough, it's a winner. It would be a bit of a pain to have to charge it every day, but if there's a campground store, office or petrol station nearby.... it shouldn't be a problem. Good luck!

I have no idea what the humidity ever is in my house i guess the weather/temps aren't so extreme down here in the South Island..

Yes im just after something that's better than nothing when i go to bike rallies which is usually 2 nights camping, there is power somewhere on site i can plug in the 45.

And all the best to you to mate :cool:

I figure you have finished your sleep based on the time difference. I would love to hear how things went with the #1 setting on the humidifier. I don't think you'll need to resort to going completely without head on the humidifier if you are willing to charge it once a day.

If you ever ride through Tokaroa, wave as you go by. I know someone there.

All the best to you as well, and, as Red Green would say: " If the women don't find you handsome, they should at least find you handy! Don't forget, we're all in this together"

I didnt use the 45 last night as i wanted a proper sleep but will do tonight and let you know, then ill do the same again on another setting.

I have been thru Tokaroa a few times , i have reliesin Rotorua.

Nice quote btw :)

Went with 1 on Humidity and down to 19c on hose temp.......5hrs was all the PS45 lasted , 1 hr less than 4 setting ?

I need to catch up on my sleep so i will try again in a few days maybe no Humidity but with water in the tank.

Hmm... That was weird. It's running in CPAP mode, so it shouldn't be varying it's power consumption like it would on APAP where it all depends on the night. If I may be so bold, try it with the humidifier set to 1 again, but turn off the hose completely. Heating the hose serves little purpose when you are using so little humidification. It's power you don't need to waste. I do have a sock on my heated hose that does help prevent rainout. But honestly, even when I used the plain unheated hose on my last machine (with the sock), I would only get a few drips in my face in the morning, but only after an 8hr+ night.... I almost miss the little bit of dripping as it used to help me wake up in the morning! Even if you don't have a sock for your hose, turn off the hose heat all together, it just eats battery.

I finally got to see my new Super Tenere today.... It's touch and go about getting the Jackery into the sidecase.... I won't know for sure until I try. If it doesn't fit, it can go in the waterproof duffel bag I plan to have on the rack/back seat. A 60 or 70 liter duffel bag can hold an awful lot of stuff and is easy to strap down.
