I have read some of the posts on batteries, etc., and I am confused.

Unfortunately, I do not understand the difference between AC/DC and how many volts, etc., my Remstar cpap uses.

Going camping in two weeks (traveling very light), and I need a batter for just one night, so I don't need one of the $300 batteries online.

The other discussions have said that I would need a DC, or maybe an AC depending, and then I have to check watts and maybe get an inverter, etc., etc.

Too much info for me. My little oxygen-deprived brain is going to explode!  :-)

Can someone please just tell me, in as few words as possible, exactly what I need?

Someone wrote that a Black & Decker Jump Start Battery from Wal-Mart would work (the $40 price is in my range for sure), but do I need an inverter, will it just plug in?

Others wrote about marine batteries, etc...

What SPECIFIC battery have you used or do you know of that I can use and buy at a store or hardware store with little hassle and won't blow up while I am sleeping?

Thanks much!  :-)

What CPAP do you have and what is your pressure?

As long as your CPAP will work from 12 VDC, and you only need one night, a jump start battery would work well (as long as the battery has enough capacity) and you won't need an inverter -- just the battery pack and a cable that you can get from cpap.com.
Here you go man this should work good for you..

Tony,

Are you going camping in a tent or a camper?

What is the voltage capabilities of your Remstar? (see your owner's manual or manufacturer's label on unit) What model is the unit so I can research the power draw of the unit.

AC = house current (110v / 220v)

DC = car voltage (12v)

These questions will offer more insite as to a direct for an answer.

This is the cable that you will need to connect your CPAP to a battery pack that has a cigarette lighter outlet (socket) on it:

--------------------------------------------------------------------------------------------------------------------------------------------------------------------

This is the the set of two cables you will need if your battery does not have a cigarette lighter socket on it. The kit includes the "12v-dc-power-cord-shielded" cable listed above and a cable that clips to the battery and provides a cigarette lighter socket.

If you have an M series CPAP or autoPAP, set at about 10 cmh2o, your CPAP will draw about one amp; and in eight hours, it will draw 8 amp hours (Ah). You do not want to completely drain the battery as that will damage it. A battery rated at 10 Ah would be barely adequate, and a battery rated at 12 Ah would give you a comfortable margin. The numbers will have to be adjusted if you sleep more or less than 8 hours or your pressure is greater than 11 cmh2o. Example: If you sleep 6 hours and your pressure is 10 cmh2o, a 10 Ah battery would be fine.
thanks, dan. when i get home from work today i will let you know what i have specifically. i am tent camping, only for one night.
i have a motorcycle battery (fully charged), don't know if that will work with an adapter, much cheaper than buying something else if it works. here are the specs that i found online:# 12 Volts
# CCA: 200 # 12 Amp Hour @10 hr rate

tim, i am going to find the exact specs for my machine when i get home tonite, in the meantime, i do have a motorcycle battery that is fully charged (an extra one) with these specs: # 12 Volts # CCA: 200 # 12 Amp Hour @10 hr rate

here is what i have: a remstar pro, model 1005961. it is at least five years old. here is what i could find on the specs: ELECTRICAL REQUIREMENTS 100— 240 AC, 12 VDC DC POWER Direct-connect cord

I am not sure of the setting I have it on, but I believe that it is high.

Any help with what to buy specifcally appreciated.

Thanks for the detailed response Tim I realized i wasn't clear enough...
This forum is really a great resource...

Your motorcycle battery is rated at 12 Amp Hour (Ah), which should be good enough for one night, although it depends upon your pressure and how long you will be sleeping. Motorcycle batteries are normally designed to be starting battery and discharging it below about 9 or 10 volts or so will greatly shorten its life. CPAPs should be used with a deep discharge battery, aka deep cell battery, which are more tolerant to being deeply discharged. The thing that is making me believe that your motorcycle battery is designed to tolerate deep discharge is that it gives the "12 Amp Hour @10 hr rate" rating, which is a rating given to deep cell batteries.

Any battery should be tested at home anyway; you don't want to be in the boonies when you discover that your battery or battery pack is defective and won't hold a charge. My suggestion would be to get the cables at http://1800cpap.com/respironics-shielded-12vdc-power-cord-system.aspx and use your CPAP powered from your motorcycle battery for one night at home and see if it works. Make sure that the battery is fully charged before you try it out. One of the cables clip onto the battery and provides a cigarette lighter socket, the other cable plugs into the cigarette lighter socket of the first cable and then plugging it into your CPAP. If it works and your CPAP is still going strong when you wake up in the morning, you have a good battery. Don't forget to recharge your battery after using it.
