Info I got off of Sleep Guide about power outages with cpap
I live in an area where the power goes out fairly often. A few things I’ve learned:
1) When the power goes out, I wake up FAST!
2) If your doctor prescribes a battery pack for your CPAP, the insurance company will likely pay.
3) If you’re planning on an Uninterruptible Power Supply (UPS) you need to be sure that you get one that’s compatible with your CPAP. All UPS devices are not alike! Some generate “square wave” output, and some generate “sine wave” output. Sine wave output is generally what we’re looking for.
4) There are different types of UPS devices, the most common being “stand-by” (low-cost, compact, efficient, but uses battery power during brownouts) and “line interactive” (high reliability, high efficiency, ideal for harsh power environments).
5) A good UPS will also protect the devices plugged into it from power surges.
I have a few “line interactive” UPS devices in my house, one on the TV, one on the computer, and one on the outlet that powers the telephone, DSL MODEM, and router. I also have a spare in case there’s something that needs to be run when there’s no power.
I have always used APC brand UPS, and have had great results with them, and I’d say they’re the top UPS manufacturer.
I haven’t yet tried my CPAP on one, though.
My ResMed AutoSet II is rated for 2.5 amps @ 120 volts, and 2.5 amps @ 12 volts DC (it has a built-in battery power connector).
