    one other oddity is if you get a mask assembled, you need a prescription. If you assemble yourself none needed.

    I absolutely agree with getting a copy of your scrip for the CPAP, then shop around. My first one, I left the 8 hour sleep study with it. I got billed each month and after a few months called to see WTF with the monthly billing when I hadn't had an appointment that month. Oh, that's for your CPAP machine. Fine, what's the pay off? I paid it off, but what a rip off. They charged me over double what it would cost to just go buy the same machine. Almost $800 in 2010 for a Respironics One with humidifier. (I still have a 12V power kit for that unit, brand new in the package, if anyone needs one.)

    A few years ago I wanted a smaller unit that drew less power for travel/camping and did an at home sleep study so I could get a new scrip. Once over that hurdle, I ordered a Transcend and the 2 day battery. Ouch on the battery, ($327). Exactly 3 days short of the 9 month warranty it died, red light, won't charge. I got it replaced by Transcend with a new one. I used the second one a few times camping. Worked as advertised, I would sleep with it at night and charge during the day's riding on the bike. I did buy their 12V charging equipment. 9 months later to the day, it dies in exactly the same way. Red light, won't charge. I call, sorry, the warranty is only good for the original unit, not the replacement one. :hair Both times they swore the batteries should last much longer than 9 months, but that's BS. I suspect it's programed into the device to die. I was using it as an inline back up battery in the house, but it stayed fully charged so wasn't getting cycled like when used for camping.

    No way I was going to cough up the $300 for a new P8 after two failures right at the end of the warranty period. I already had Makita 18V tools for the house and as a back up for emergencies I had previously purchased a dual USB charging unit that fits to the Makita 18V batteries. THIS After reading and re-reading the CPAP power supply requirements, the Transcend P8 battery pack, the Transcend 12V charging unit, etc, I realized that everything is pretty damn close for these Lithium batteries. The Transcend CPAP runs on 19V. The Makita 18V batteries are really the same as the DeWalt 20V batteries, and nominal output is close enough to what the CPAP will tolerate. I pulled the Makita USB charger apart, (2 screws), and soldered the pigtail from my P8 to the main two input bars and put it back together with some strain relief and a hole for the wire to exit the plastic case.

    End result is a 4Ah Makita 18V battery will power my Transcend CPAP for two nights, just. Keep in mind my pressure is not your pressure and the more pressure you run, the more the battery will drain during the night. I have a fairly low pressure and the machine is in auto, so I don't know exactly what it is. Further, I can use the Transcend 12V charging unit to charge the Makita battery off the bike while riding. It seems a little slower than the P8 charged, but it's hard to tell. I tested it with a two hour ride and the Makita battery went from 2 bar to 3 bars. The P8 had over charge protection and an indicator light that told you when it was fully charged. I don't have that on the Makita, so I will need to moniter it a bit more until I have some idea how long it takes to fully charge the 4Ah battery.

    For my needs, I could get away with the smaller 2Ah battery for a single night if I knew I was going to be riding every day. The 4Ah gives me some leeway if I'm going to be camping a couple of days or more and maybe not riding every day. Makita does sell 5Ah & 6Ah batteries too.

    If you download the Airmini App to your phone you can connect to your phone via Bluetooth and it can give a daily report on current pressure used, Average pressure, how many events you may have had during the night, mask seal and length of sleep etc, keeps about 1 month of data to look back through.

    Yeah, I have that app. It’s very good.
    Funny thing though, I live in Australia.
    When I was in Europe last year the app gave weird readings. Like when I knew I had slept for 7.5 hours it would say 4hrs 50 minutes.
    Weird. Like the different time zones affected it ?
    I just didn’t bother checking the app after a while over there.

    @ejm4 under federal HIPAA law you are entitled to copies of any records including test results, prescriptions, diagnostics and basically everything in your medical record. https://www.hhs.gov/hipaa/for-individuals/guidance-materials-for-consumers/index.html Your doctor has NO SAY over where you can by a machine or equipment. You can contact your insurance company and find out what suppliers are in-network for your insurance. Your doctor sounds like he has immense conflicts of interest and is getting kickbacks on sales or owns the dispensing DME. You should consider transferring all care to your primary doctor that you trust for future prescriptions. There is nothing that requires you to use a specialist for coverage. Any online supplier should be able to send a fax or email to your doctor's office at your request, and receive your prescription information. If your doctor fails to do this, you need to file a complaint at the page linked.

    This. I ran into the issue of my quack refusing to give me copy of my prescription. Fought me like a tiger for 2 months, he finally relented telling me " You must have a new prescription to get a new machine" My ass, just ordered a new machine online

    This is getting weird. It must be common knowledge across the land how to rip patients off, and everyone's* doing it! At least I can say that my pulmonary specialist isn't. He talked me out of even considering a new unit to replace my 8-year-old CPAP.


    *Unsupported exaggeration, but it sounds about right.

    I use an XT auto CPAP when I travel. I've had it in my old hard bags a few days and it doesn't take as much space as my big home unit. I wrap my headgear around the XT. I have not used it on battery power, but a combo battery - AC converter should work & it will charge on the road in the daytime. The XT is 110 Volts so I can't run it from a bike battery. If I am traveling by air, this keeps my suitcase to carry-on.
    I also use a travel air hose: https://www.amazon.com/gp/product/B01B5DHJ5O/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. It works pretty well. I need humidity so I use an inline humidity capture knob. I also use a device to reduce the pump vibration https://www.amazon.com/dp/B01FRIOEUQ/ref=psdc_8627104011_t2_B01B5DHJ5O.
    Like everyone else I wondered if I was going to overflow, but I got it to fit.

    Horse shit. I've been using my original prescription for the last 25 years and 4 CPAP's. The first one was my initial CPAP that I got through my sleep clinic when I did the original study. The next 3 were from online I ordered myself.

    Just got my new Resmed Air Mini. I was shocked to see how small it really is. I'm digging the size. Now I need to get a decent travel battery that can be charged from bike power. I know its been done to death but do you all have any opinions about which battery would work best? I know it uses 24V. I know almost nothing about wiring and electrons and such and cant figure out what I need.. The Resmed battery claims to have a 12V charger, I assume it would use some sort of "step up" to 24V/? Im so confused

    I've got a Z2 travel cpap which is of similar sized to the Air Mini. I picked up this Antigravity PS-45 ps45-power-station and have used it a few nights although not back to back nights so I don't yet know how long it will last on a single charge. It is purported to be able to be charged off the bike's 5V accessory socket but I have not verified or tested that. The PS-45 is small, and relatively light weight. Great for the camping off the bike and doable for hiking although I wouldn't want to do a through hike with it! This is my entire travel cpap and battery kit packed away in a kid's lunchbox.

    Here is an interesting hack: Jailbreaking your Resmed Airsense 10 https://airbreak.dev/

    This team shows that the Resmed Airsense 10 Autoset has all of the necessary hardware and sensors to be converted to VPAP S, Vauto, ST, ST-A with iVAPS and ASV. Put another way, the $700 Autoset can be reprogrammed using this hack to create a $4000 advanced non-invasive ventilator.

    I also have an AirMini.

    I bought the very expensive battery to go with it. It lasts about 1 1/2 nights. That leaves me with anxiety if I cannot get it charged the next day for any reason.

    My solution was to buy a 24 volt lithium battery off AliExpress and make a buck to regulate the voltage to the AirMini. You can see this stuff in the attached pic. I wanted the 24v since it suffers fewer losses to the AirMini. You could get a comparable sized 12v lithium battery but it will decrease the amount of time you will get out of it since the loss from 12v to 24v is greater.

    The AirMini needs proper voltage. You don't want electrical supply issues with that piece of expensive equipment.

    From the battery to the AirMini is my regulator. It controls the 29+- voltage from the battery and controls it down to 24.1 volts.

    The buck laying on top is to go from my bikes SAE connector to charge this battery. It takes input from the bike and ups the voltage to 29.2 volts to charge the battery. It is one way to keep the lithium battery from back feeding to the bike.

    The battery lasts for 5 full nights plus. It has a volt meter and dual USB ports. I have about $250 US in this setup which is less than the cost of the med battery. I take it too. I am paranoid about running out of battery so like the backup.

    I hope this helps.
