hydro was out...used generator for CPAP
Well...our hydro was out and the voice recording at power company said it would be out for two days. I know my equipment instruction booklet says to never use an extension cord. I am not sure why, but am sure that at some time I will be visiting somewhere and not be able to reach a plug without an extension cord. Last night we hooked me up to a generator. I was a little worried that I might blow up in the night, or ruin my machine. But, I woke up this morning and my machine did too..lol. Our hydro is back on now...but is it ok to use a generator with my equipment?

RE: hydro was out...used generator for CPAP
Yes, as long as the generator is also "clean" enough for a computer/electronics. Most will say what it can or cannot be used for.

Electricity can be "dirty", or, more accurately, noisy. The more noise, the dirtier. Computers and other electronics need clean/quiet electricity.

Whenever I travel, I use an extension cord because plugs in hotels are never conveniently placed. Electricity gets weaker the further it has to go from the source. However, the bigger the cord, the better the power on the other end. But xPAPs draw so little, a simple two wire cord would be more than enough.

Thanks Paula for the info. I must check out our generator and see if it is ok for electronics. Several of our neighbours have the same one and hook up their tv and laptops. Nothing has been hurt yet, so likely ok.

RE: hydro was out...used generator for CPAP
Most of the smaller ones are geared toward that nowadays. The larger ones in the frame may not be. If it is marketed toward the homeowner, it is probably safe. But if it is marketed toward construction or other job sites, it may not be. But they've done a lot to "clean" up generators lately.

I wonder if a UPS system would work with it? Meaning plug the UPS into the generator and then plug the xPAP into the UPS? I know mine said it helps to keep the voltage the same in case there's fluctuations, maybe it also cleans it up?

RE: hydro was out...used generator for CPAP
A good surge protector would be a good idea when connecting a CPAP to a generator. Anything could cause a surge, if not the generator itself then something else that's also running off the generator.

Yes, Paula, a good UPS will also help clean up the electricity. It would be especially helpful keeping the voltage constant if something like a refrigerator that's running off the generator kicked on while the CPAP was running.

The reason they warn you not to use an extension cord is because a long thin one could lower the voltage supplied to the CPAP. As long as you have a good quality extension cord you should be fine.

RE: hydro was out...used generator for CPAP
The so-called 'Inverter' generators are generally very good in the smaller sizes. They actually generate 12 Volts DC and have a Sine Wave inverter built in to produce the mains voltage of 240 Volts in Australia or (presumably) 110 volts in the USA and Canada.

The older style generators can be very bad news for electronic equipment.

Do they have a 12-volt DC jack? If so, I could just plug my CPAP machine directly into that, skipping the inverter, transformers, and converter.

I just looked up some 900W Inverter Generators and while they do have a straight 12V DC output (the ones I looked at) they were not the Cigarette lighter style outlet. They use various configurations of a dual prong plug, slanted in all different directions and such to ensure no one tries to plug an AC plug into a DC outlet. I don't know if this is standard as I don't have a generator, but...

As always, YMMV! You do not have to agree or disagree, I am not a professional so my mental meanderings are simply recollections of things from my own life.

I wonder how long a CPAP without the humidifier would run on an ordinary car battery while still leaving enough charge in the battery to start the car.

RE: hydro was out...used generator for CPAP
Depends on the battery and it's charge capacity.

We discussed this in the camping thread and the 'be prepared' thread. I think one guy could get 5 nights out of the battery situation he had.

If I can find my volt meter, I'll do a test with the battery I've got. I know the meter is around here somewhere....
