What UPS (uninterrupted power supply) do you use for your Fisher & Paykel SleepStyle?

I have a Fisher & Paykel CPAP. I am searching for a UPS. 

What UPS (uninterrupted power supply) do you use for your Fisher & Paykel SleepStyle? What are your experiences with it? Does it kick in automatically and quietly when power goes out while you are using the CPAP?

How long do you need the UPS to provide power?  You will need to calculate the power draw, either by using the information on your power supply or from F&P documentation.   This should provide a per hour requirement.  Due to energy loss during voltage conversion, UPS systems are very ineffective for long term use.  Also, some UPS systems have an alarm that will sound while they are in use.  This precludes any sleep while it's active.

If you can provide the power supply's wattage and the desired run time, we should be able to help.
