Anybody have experience with CPAP.com Battery Pack?

[Brian000]

Has anybody on this board had any experience (good or bad) with the CPAP.com battery packs? Do they perform as described? Would I get 8+ hours (w/o humidifier of course) at 11 cm pressure on a PB? I'd love to go tenting again and not have to be at a power camping site!!

Hola Brian 000:

Yo compré la Everest 2 con “pack battery”, en adicion a eso compré el “cargador del carro” el que se conecta al encendedor. Mi maquina esta calibrada a 8 cm. Mi sugerencia es que pruebes en tu casa como te funciona, la unica forma que puedes saberlo es comprándolo y por tu vida muy bien vale la pena pagar lo que cuesta, sino te funciona muy bien puedes encontrar a quien hacerle un donativo.

I suppose even a quiet generator is out of the question? Disturbs other campers peace and quiet - but then so does snoring : )

I use my cpap when sleeping in a tent. It's hooked up to a small battery and a converter. I don't know the details, my husband set it up. Since it's 2:40 AM, I probably shouldn't wake him to ask! I'll ask him later in the morning and post back.

Here are some links from RestedGal on battery operation and camping;

Okay, I'm back. Here's the setup I use when camping;

My husband did extensive research on reviews on the Internet regarding using battery power for cpap machines. For my machine, a ResMed Elite S8, most of the postings indicated to be sure to use the ResMed 12Volt converter because it stabilizes the electrical input and lessens the risk of damage to the machine. This converter has a cigarette lighter plug. Handy for when you have to sleep in your vehicle during bad storms. Been there, done that.

To connect the converter to the battery, we use a 12Volt recepticle with alligator clips. We got this at Radio Shack.

For the portable battery power, we purchased a 12Volt gel cell sealed non-spillable battery, a Werker WKG12-31J-EP. We purchased it from Batteries Plus. It is the type of battery used in mobility equipment (scooters and such) and allows for a deep draw down without damage to the battery. We've used it while camping for 3 days without a problem with no recharging and that is probably the maximum you'll get out of it until you recharge again. If you are camping longer than three days and are unable to charge in the conventional manner, there are solar chargers available, but we have not gone that route yet. You can check Cabela's online and you'll see a solar charger used for wildlife feeding stations for $29.00. We don't know if, or how well it would work for the cpap application. We haven't checked into the specifications yet.

The battery weighs 23 pounds. It comes with a handle so it's fairy easy to transport. My husband made a crude, but effective way to transport it. The battery is sitting in an empty Fla-Vor-Ice Popsicle box and the converter and the 12Volt receptacle tucks in nicely next to the battery. Then, he took the Handyman's Secret Weapon, duct tape, and taped the battery to the box by wrapping tape around the middle of the battery and around the box. That way you can carry it by the handle, have all the equipment with it and most importantly, all the parts are together and there's no chance of forgetting something.

This whole setup can be put together for approximately $200.

One night when the battery died because "someone" forgot to charge it, we plugged the converter into a portable jump starting battery pack and it worked for the rest of the night, so it's handy to have one of those as a backup. However, we wouldn't recommend this as your only source of power, because the batteries in those battery packs are most often lead acid and don't tolerate deep discharge very well without damage over time. Unless, of course, your portable jump starter is a high quality expensive unit. Then this may not be an issue. We don't use one of those because the setup described above does the same thing and 1/4 of the cost.

Caveat. I have not used the humidifier with this setup. We don't believe we would have enough power for a three day camping trip if I used the humidifier. I haven't found that I needed it while camping anyway.

Hope this helps.
