Goal zero yeti 150 & cpap

You need to post what model Cpap Machine you have. My machine is a Respironics M Series BiPap. It runs on 12v. I use a 12v receptical by my bed in the RV to power my machine.

I don't have a CPAP, but I do have a Goal Zero Yeti 150 (and a Yeti 400). You should be aware that the Yeti 150 outputs Modified Sine Wave power (MSW), if that makes a difference for a CPAP. The Yeti 400 is Pure Sine Wave (PSW). I found that a fan would run only at half speed using the MSW from the Yeti 150, and I think there will be other issues like that. If I knew more about how CPAPs work I could give you more info, but I've never even seen one.

so that is basically just a storage battery that you can charge with an addsitional solar cell, wall outlet, etc.? if so it is an expensive battery pack. and to use it to put out 120 which needs to be converted to 12 volt for most? CPAPs seems a little silly to me. don't think a CPAP without humidifier will be that amp hungry but don't remember the numbers to run one 8 hours.

I would say NO based on this spec sheet... It shows the Inverter as a MSW TYPE inverter and the battery that is being charged while in high sun is a very small battery to operate a CPAP machine very long.

It appears the YETI 150 is more or less a good power source unit using solar power that is used to re-charge things like USB port, cell phone and computer batteries etc...

I would want some extra power to make sure the CPAP machine would run the whole night without any problems.

Appliances that uses motors and electronics do not do well being run by MSW type Power Inverters - especially the cheap built version AUto Parts stores Power Inverter units.

I do not have any experience with the CPAP machine but recently was talking with AIMS Inverters Technical folks about their 600WATT PSW AIMS Inverter performance and they brought up the fact that this unit solves the problem alot of their users of the smaller PSW Inverters running the CPAP machines. I assumed they was talking about the popular 150WATT and 300WATT PSW Power Inverters.

I think your best bet is to get a CPAP machines that runs from both 120VAC and 12VDC or at least get a medium power POWER INVERTER like the AIMS 600WATT PSW Power Inverter (AMAZON) that states in their description being used with CPAP machines.

Another issue that is discussed on the forums is using the 12VDC 8AMPS socket that is associated with the BAT WING Roof OTA Antenna panel. This would not be a good place to plug in a 300WATT and UP Power Inverter to use. You would want to connect directly to the Battery Bank terminals and then run an extension cord from the remote Power Inverter Installed location up to the bedroom area where you are sleeping using the CPAP machine.

Being a somewhat medical thing that is required to work for heath reasons you want to beef up on these things to insure great performance.

Would not be a good idea to run out of battery power at midnight or sooner on a poorly designed power setup with something as important to you as the CPAP machine is.

Need to check your CPAP power specifications before setting up any power sources for it.

Just some of my thoughts

My CPAP runs on 12V or 120V and I use a 12V outlet at the beside nightstand. Also, Respironics recommends a PSW if you use an inverter.

Our CPAP operates off the RV's 12vdc batteries, nothing else needed.

On Amazon, I found some Q&A on the Yeti 150 and CPAP. here

Reading what they say makes me doubtful that your Yeti 150 could run the CPAP for very long. Plus, you'd have the issue of recharging the Yeti daily and it seems to take a very long time for recharge.

Perhaps a Yeti 400? You need a fair amount of power for a full night every night, and that is a pretty big drain on a smaller Yeti.

My CPAP runs fine on the 12V power from an outlet in my RV (2 6V batteries which store 110 usable amp hours and recharge from the truck alternator). I also have tested it with a small Duracell inverter (100W) and it ran OK on that. Sometimes people get a separate 12V deep cycle battery and dedicate it to powering the CPAP, but that still leaves the issue of frequent recharging.

Better to do a proper solar system. The Yeti are $$$$ for $$ value as far as capacity goes.

Is anyone using a Goal Zero Yeti 150 to power their CPAP? If so, I would like to hear your feedback in how well it works for you.

Thank you

Ugg one more thing to lug around and manage, no thanks.
Use the existing power system, upgrade as needed.

Thank you for the replies. My cpap is a ResMed Air Sense 10 that runs off of ac or 12v. I was looking at the Goal Zero 150 as a way to power the cpap and save the camper batteries. I do appreciate the input you have provided.
