A small cheap underwater breathing device?

Power supply for CPAP breathing device.

• I am looking for a power supply for a CPAP breathing device so I can go camping away from normal electrical power. The device is an Aria lx produced by Respironics Inc. 100-200 VAC, 50/60 Hz/ 12VDC Class I Type BF Current Consumption: AC 1.0 A max/ DC 3.0 A max Continuous operation. The device has a 12 volt socket. I need something that can be used repeatedly for at least 3 consecutive nights of maximum 8 hours. I contacted the manufacturer by email but they declined answering my question. Charging the power supply from an in-car 12V socket is an option. I use a tent for camping and, even if it was practical, would be adverse to using a gas producing supply like an automotive battery, not to mention the possibility of acid spills and the effects of repeated depletion. Weight may also be a factor, for although travelling by car, I am a senior and find weights over 40-50 pounds a problem. Power supply must be available in Canada.

  Dear sarnian-ga; Thank you for allowing me to answer your interesting question. I?m confident that what you are looking for is called an ?inverter?. I have some workable options that you can use and if nothing else, they will give some ideas for products you can shop for locally that can get the job done: Here is a 125W DC-AC Power Converter that allows you to plug in and operate any normal household appliance. (US $24.95) GADGETS TV.COM http://gadgetstv.com/te-449.html The CPAP machine can easily operate from this power plant and in the morning you can run your car for a few minutes and restore any power drained from your car battery so the process can be safely repeated the next night without risk of running your battery down. . . . . . . Here are some other alternatives: TRIPP LITE POWERVERTER: With one of these little miracles you can plug in anything in your car that you can plug is and use at home. All you?ll need is a common extension cord to run over to your tent from your car?s cigarette lighter.

Here?s another one that?s small enough to carry in one hand. It has an input voltage range of 11-15 VDC (as a 12 VDC yours fits the requirement) and even has a 3 prong plug-in if you need that.

It?s a palm size device that plugs directly into your car?s DC outlet and, VIOLA! You have instant electricity!
