Small pure wave invertor for CPAP machine?
I want to take my CPAP machine on a 2 night camping trip with the grand kids but I need a small pure sine wave invertor. I also don't want it to be
noisy either.
Any recommendations?
Unit's power supply is a 90W unit
Typical Power Consumption: 53W (57VA)
Peak Power Consumption: 104W (108VA)
If I did my math right, a 105 amp deep cycle should get me through 2 nights at 7 hours each? What I don't know is how much is lost inverting.

Inverter specs will tell you how many amps they consume doing their magic. Not much. Check out Amazon.
A smallish inverter will be noisier because its cooling fan will kick in when it's working hard. Consider a 2000 watt inverter, you'll be able to use
it for other things too.

No can leave home. I know from Les who could not even sleep on our overnight plane trip. Terrible.

I have a Jackery 1000w Solar Generator. It puts out a pure sine wave. I can charge it using 12v, 110v or solar panels.

I don’t need/use a cpap, but I have seen a number of people camping using the battery-powered travel cpaps. I understand they hold enough charge
for 2 nights, so just need recharging every other day.
I think using one of the travel units sounds easier than what you are trying to macgyver.
Woke!

Appears you don't have sleep apnea. They are medical devices, not a down comforter.
I bought a transformer unit for about $200 from cpap outlet and hook it up to portable car battery I carry when truck camping. I get 4 nights use so
far even with humidifier attached

I've had my buddies use their CPAP machines on my modified sign-wave inverter with no problems. Are you sure you need a pure sine-wave?

you know i grew up in the 50's 60's and 70's...
an adult in the 80's and 90's and there were NO CPAP machines
how did people sleep?
how did we go camopping?
well...as i remember it...you worked hard...
got tired...and fell asleep
the medical industry found a "cash cow" with the CPAP machine

I have experienced the signs, and symptoms of obstructive sleep apnea most of my life! It was not officially diagnosed until eight or ten years ago,
when my cardiologist signed me up for a sleep study.
The first night was an observation and measurement exercise that recorded the frequency and intensity of the events. I was at the low end of the
spectrum for health concerns, but I returned the next night to repeat the study with a cpap device.
I could not tolerate the procedure well, and long before the night was over, the study was ended and I went home to get some sleep.
The one thing I would like to add to this conversation, is that the frequency and intensity of my episodes, appear to be directly related to the
frequency and quantity of alcohol consumed.

cpap battery or invertor?
depending on brand some will work directly on 12 volt power or have a decicated battery available (usually without heated moisture) typically direct
12 volt will be most efficient. brand provided battery next.

No need for you to continue to post about this subject, you are uninformed. Those that have had their quality of life improved by CPAP(myself
included) do not welcome your comments.

And just perhaps you have sleep apnea and the nightly sleep/oxygen deprivation has affected your brain and made you think/say cuckoo things, eh?

IMHO Santiago is correct to want a pure sine wave inverter. Electric motors run more efficently. I'm assuming CPAP machines have electric motors, I
don't know for sure.
"Modified Sine Wave (quasi-sine) A modified sine wave inverter actually has a waveform more like a square wave, but with an extra step. A modified
sine wave inverter will work fine with most equipment, although the efficiency or power of the equipment will be reduced with some.
Motors, such as refrigerator motor, pumps, fans etc will use more power from the inverter due to lower efficiency. Most motors will use about 20% more
power. This is because a fair percentage of a modified sine wave is higher frequencies – that is, not 60 Hz – so the motors cannot use it."

I know my little shop-vac hates my modified SW 1000W inverter. The motor runs HOT and at slower RPM.

remember all you nite time "maskers"...
clean those things daily or you'll be "sucking mold"
i'm still amazed at how many people use a CPAP
they draw very little current but make noise
how does the person next to you sleep?
im just saying that for 2 days "camping" you could leave a CPAP home

I do not use a cpap, but I can gaurantee that you would rather listen to that, than my horrendous snoring! I don't know this for a fact, but don't
the cpaps cut down on snoring?
