Boondocking w/ CPAP: Suggestions?

[buffalobillh]

In situations in which a generator might not be an option, what do you suggest? I did search the forum and saw info about www.batterypowersolutions.net. Most CPAP batteries and systems look to be expensive, so are there any other ideas?

Thanks!

Solar + golf cart batteries = dry camping.

Maybe a separate battery and a small inverter dedicated to the Cpap. You could use a small solar charger to keep the battery topped off. There are probably better ideas but this is a start.

Get one of these - Schumacher XP2260 1200 Peak Amp Instant Portable Power Source and Jump Starter and a 12volt adapter for the cpap. Runs 8 hrs.

^^^ It has a built in inverter and the internal batteries, when fully charged will run a CPAP (with humidifier turned off) for 2+ nights without recharging. Lowe's typically sells them for $130 but often has them on sale for $89.

I have a couple of options. I have a 12 Volt power supply to use with my golf cart battery power via a cigarette lighter plug in. I also have a separate battery pack for the CPAP. I can also plug in my small inverter. I know because I misplaced the 12V power supply once. . .

I do not ever use the humidifier function on battery power, though.

DW uses this set up. Boondocked for 3 days without fail. Works for her machine anyway. Check Resmed.com for a set up for your Cpap..like Madmaxx said, she doesn't use humidifier either! Happy boondocking

I added an extra 12v battery into my 5th wheel and an inexpensive inverter from Walmart. Added a 12v power port in bed base. Works fine for me.

My wife also uses a Resmed CPAP machine which usually runs off of a 120vac to 12 vdc wall transformer. It also came with a dc to dc adapter which takes 12v to 24v dc input and outputs 12v dc to the CPAP machine. So I got a second 12v marine battery and hooked it in series with the main RV battery and then ran both the 24 and 12 volt lines (properly fused) to a switch by the bed and then to an automotive dc outlet. A switch prior to the outlet allows me to select either the 24 or 12 volt feeds. Usually run off of the 24 volt line which allows use of the humidifier.

When we started going to NASCAR races, my wife’s CPAP was A/C only. We picked up an APC Smart UPS 750. You have to be careful if you go this route because most UPS’s have alarms that sound when power is lost. You need one which allows the alarm to be silenced. The Smart UPS line had this feature. It had just enough capacity to run through the night.

Today, her CPAP is DC powered and came with a 12 volt rechargeable battery pack which connects via a cigarette lighter plug and receptacle. Without the dedicated battery pack, you could probably wire it directly to the 12 volt battery(s) in your trailer. You could probably speak to the pulmonologist about the new technologies.

I just wired a 12v outlet to my coach battery and use that, proper battery management gets me 4 days on a battery with no humidifier

Thanks, everyone! Lots of great ideas to work with.
