[Electronics-talk] Storable energy for prolonged periods of power outage

[Steve Jacobson]

Peter,

Some CPAP machines that I've seen have multiple power inputs with different voltages.  These make it more difficult to power with anything other than a backup generator.  However, some have a separate power supply with a single plug.  One that I worked with many years ago had a twelve volt power supply, so it was pretty easy to use a twelve volt lantern battery to power it.  However, the older ones drew enough current to cause the battery to not last long.  

My experience with doctors is that you will be lucky to find one that can do any more thatn say if there is a unit with rechargeable batteries.  On the other hand, there may well be units with an external power supply and a single input that would be fairly easily connected to an alternative power source.  Modern generators provide pretty good electricity, but you will pay quite a bit and youmay not get it working when you need it.  If some machines support a connection to an automobile, you could get a 12-volt motor cycle sealed storage battery that you could keep charged, and that might work well.  Maybe it would be good to see if the doctor could give you contact information for CPAP manufacturers.  Also, these machines are so common now that perhaps you will find out about one with a rechargeable battery.

I would be interested to hear what you find out.

Best regards,

Steve Jacobson

Good afternoon everyone,

     Since I have Sleep Apnea I use a CPAP machine to enable me to sleep 
at night. The unit I have does not have any sort of backup power supply 
not even a rechargeable battery. If you asked me medical equipment like 
this should come with a way to power the device even when power to your 
home or office is out. I'm in the process of addressing this issue with 
the doctor in the hopes of getting a CPAP machine that includes a 
rechargeable battery so it can be operated in the event of a power 
failure. This happened several years ago and it was not pleasant! If 
anyone has used a generator to power medical devices such as this I'd 
like to hear about your experiences. All the best.

Peter Donahue

We thought about getting a marine backup battery but those only hold a charge for 12 hours. I didn't want a flooded basement (it was a finished basement) so we priced out a whole house gennorator and got one. When the power was out, I was real glad we had it. If we still lived in that house, I'd be real glad we had it. We took the gennorator with us when we moved to a house that didn't have as many power failures as the previous house, nor did it not have a sump pump. It was then that I decided it wasn't as critical as it had once been.
