Any of you old bastards out there use a CPAP? No, I'm not over weight....I snore like a **** though. Anyway...I'm going camping in the truck and need to plug in and run my CPAP all night...is this going to drain my battery dead? No idea what this draws...probably as much as a very small fan on low.

 

Hey, look at the back of the machine see what the amp draw is, 400w is ~3.3 amp @120v...its just a big fan...I was just reading up on the invertors and the other guys saying the truck has to be running?

Hope this helps..

 

Ever check out the 2k-2.2k watt 'suitcase' inverter generators? Honda and Yamaha make the best of course, and there are a lot of lesser/less expensive options. And larger options. Without even having to modify one for a fuel tank extension or whatever, you should be able to get 8+ hours easily at 400-ish watts. Super quiet. Great for running all kinds of little/medium things, sip gas...

 

I don't think the 110 outlet works with the truck not running so you would need a 12v cpap and a PowerPoint that stays on (see Forscan sticky) or a small generator like suggested.
My wife is looking at smaller travel sized cpap machines for me... I wisely did NOT mention they can't get much smaller than what I have.

 

I use a Res-Med cpap, and here is what I do: I have a 12v cord/ adapter, and i use a small motorcycle or waverunner Walmart battery. I can use it for at least 2 nights, and most of a third night without a recharge. When i do need to recharge it, I jumper it to the truck and let it sit for an hour or so, and then idle for 20- 30 minutes and viola, good for several more nights.

 

Nice. I'll remember that if we don't end up with a RV.

 

You should get a deep cycle marine battery, it will probably run your cpap machine for a week.

What the hell is a CPAP? Guess will google it. I snore like a bear sometimes, but my wife too, so we both are kind of used to each other snoring. Just when she's snoring like a ****, I can't sleep, but just kick her, and usually stops long enough to fall asleep. Ha ha.

 

CPAP - Continuous Positive Airway Pressure. Helps prevent sleep apnea by keeping your airway under pressure. I use one, as I suffer from both a soft palate deformity (birth defect) that causes obstructive sleep apnea and central sleep apnea, which is a neurological disorder. Yay me.

As mentioned, the 110VAC outlet only runs when the engine is on, so scratch that.

For everyone saying "it's just a big fan"... not really. The unit I use has variable pressure, sensors to determine if I'm entering an apneic state causing a pressure increase, a heater/humidifier to heat/humidify the air so you don't get a stuffy nose, and heated tubing to prevent rain-out. Those last two pieces really suck the juice. You don't have to use them... simply turn off the humidifier and use regular tubing... if you can stand the cold, dry air.

ResMed has a pretty good guide for sizing purposes:

Using the common AIrSense 10 Elite at 8cmH2O pressure with no humidifier, the current draw is 0.79A. Compare that to the same unit running 20cmH20 pressure, the humidifier, and the ClimateLine heated tubing at 5.61A. In the first case, a 10Ah battery is sufficient for 8 hours. In the latter, you'll need 68Ah of battery (that's larger than the battery in most F150s).

 

You can also pick up a dual fuel and run off LP if your in a trailer. Saves hauling gas.

Are you camping IN the truck, or in a travel trailer? If you're in a trailer, a good deep cycle should work. You could always get a dual battery setup. Depending on your electrical setup, you may still need an inverter.
