Need battery operated CPAP for camping

It help you to charge your cellphones and also help you cook something...Bigwink

The biolite camp stove looks like a handy gadget to have. It doesn't look like it would last 7 hrs though to power my cpap all night unless I stayed awake to keep adding twigs to it. That kind of defeats the purpose of the though!

I did end up buying the set up to use with a marine deep cell battery. I'll buy the battery once we're up there since I don't want to haul it on the plane. Is there a way to recharge the battery from the car or a solar panel as someone else suggested? We're going to be camping for 3 nights and I don't' think the battery will last that long without being recharged. I can't find how to do it on the internet.

Deep cell batteries need to be charged differently than car batteries. When you look into chargers, make sure it can handle both.

Go to any car parts store and ask them what they have.

You could just buy a spare car battery, swap it back and forth in your car, or charge it by connecting to you car via jumper cables or the cigarrete lighter socket. The only diference in a marine battery is that it has thicker internal lead plates to make it last longer in deep charging cycles, as opposed to the shallow charging cycles typical of a car battery. For a few nights camping once or twice a ear, it ain't gonna make any difference.

For the real cost of the connection, it is better and safer to add a small secondary electrical box with the specific lines that you would want to power with a changover switch to move the second panel from outside power to generator. Yes it costs a bit but you and your loved ones will be safe. It is a lot cheaper than an automatic system especially if you only have a manual generator like I do.

If you try the double male plug you are totally liable for anything that happens and your insurance will not cover any damage. I am an experimenter.inventor but I would not have a double male electrical cord in my house just in case someone thought that it was an extension cord.

I just did a search on the unit that I think that you have and it appears that the AC power cord can be removed from the unit (it unplugs) and a Universal 12 Volt DC Power Cord can be plugged into the DC connector on the back.
You should be able to find one at a Radio Shack or similar store and they could confirm the plug and polarity of the connector (though universal normally means that it is + to the center and - to the outside and is the most common plug size, so it should be quite cheap). Any automotive store would sell a clip on accessory socket for the cord to plug into (and it would provide a connection point if you use a car type solar cell).
There are many 12 volt solar cell chargers that would normally be used for cars that would extend the life of the battery in the wilds (and at home).

I have found that the Battery Geek style battery available on various websites are worth the money I spent because of their size, reasonable weight, and the ability to take them in a backpack, on a plane, etc.

I find myself in the same situation. I've gone on several two-nighter camping trips. I wake up often and toss and turn. I tend to be able to get enough sleep to function and even drive home.

I have a week-long camping trip coming up in July the Royal Rangers Nat'l Camporama. The very first time I've done a week long overnight outing.

From what I've read I've decided to go with a marine deep cycle battery. I will need a solar panel to charge each.

I'd like to know what size marine battery to buy?

I need to know what the lowest wattage solar panel I should buy to charge it with? I've checked into: Sunforce Solar Battery Maintainer - 1.8 Watts / 125 mAh, Sunforce Solar 12 Volt Battery Trickle Charger - 5 Watts / 350 mAh, or the Sunforce 15 Watt Solar 12V Battery Charger - 15 Watts / 1 Amp. I am thinking I should go with the last one that states 1 amp.

The bigger the battery, the better. Unless weight is a consideration.

Will you use a heated humidifier while camping? If so, it'll require a lot of extra energy.

I don't know about the size of the charger.

To be on safe side I'll go with the largest one in the solar panels.

No humidifier my cpap doesn't have one.

If I understand what I've researched so far is that a deep cycle battery rated at 50 amp hour with an 80% discharge will run my .9 amp cpap for approximately 40 hours? Given that 40 is 80% of 50 and my device rating is rounded up to 1 amp.
