Can anyone recommend a battery for my Philips Respironics DreamStation?

I sometimes sleep in my car for up to 90 days straight, and do not have electricity to power my CPAP. So I need a battery that is portable and that can be charged quickly, like at a library, gym, or while driving. I have a Philips Respironics DreamStation Auto CPAP Hum DOM. It uses 12 V.

Would this work:

coupled with this cord:

Is there a cheaper battery? Can I just shop for any CPAP lithium-ion battery? Will they all work?

Thanks!

What type of car do you have? Perhaps you could plug in to the car and have the battery recharge when the car is driven, especially if you can do without a heated hose or humidifier.

Depending on your situation, I have a solar panel system and an AGM battery from Harbor Freight along with the vendor DC converter from our sponsor that would be less expensive than what you have shown.

Thanks prodigyplace! I actually am not worried about recharging it, since batteries are easy to charge while driving (my car has a 120V outlet, plus 3 12 V DC outlets and 5 USB outlets and I also have a DC to AC inverter). But I am trying to find out what battery I need to buy for my CPAP machine.

Thanks for the link. That is really expensive, but I might have to get it if nothing else works.

Ok, I see you updated your post.

I have a regular minivan. The solar would be nice, but I hate the idea of altering my van since I may trade it in a few years. But I like the idea of having that kind of power.

Thanks BTS! I guess I have some research to do. I didn't realize there were so many CPAP shops online.

Yeah they are endless and stay pretty consistent on pricing ...

You might read the post under yours, if the answer's not there there is no answer. Jim

The solar panel I got is free standing, https://www.harborfreight.com/100-watt- ... 63585.html

Here is the battery I got. https://www.harborfreight.com/12-Volt-3 ... 68680.html

It looks like you would need this for your machine: https://www.cpap.com/productpage/pr-dre ... -cord.html

and something like this https://www.amazon.com/KUNCAN-Cigarette ... 01MQPQLNM/

I just finished testing a jump start pack...

viewtopic/t171369/Airsense-10-powered-b ... -test.html

but it is an expensive way to go. That particular pack will charge from your 12V power plug in your vehicle in about 2 hours, or from a cell phone charger in 8+ hours.

A better way to approach this would be to install a second battery in your vehicle, hook up a dedicated 12V plug to use for your CPAP, and also install an isolation diode. This second battery would charge while your engine is running and the diode would prevent the CPAP from drawing down your main battery. This approach would also be less expensive and with a larger battery you could get several nights of use even if you don't drive every day.

Thanks!

Since you're using it in your vehicle, weight isn't the issue. Weight is the only reason to spend the extra money on LiIon.

The most cost effective thing you can do is get a 35ah scooter battery. rig up a charging cable from the cigarette lighter to that battery, and use it to power the cpap. That way you *can't* over-discharge the vehicle battery, and will be able to start it the next morning... then just let the battery charge while you're running the vehicle.

Check out Paxcess 100watt power generator at Amazon. Seems reasonable if weight isn't an issue. Search on YouTube for this item with a Resmed CPAP machine. In Canada, this item is under a different brand of Uxcell.

I have the Medistrom battery pack....available for 12V too. This can be used on airplanes where weight is an issue....pricey though.
