At 12 Volts it needs just over 6 Amps and if using 110 2 Amps 240 Watts. If I go with just a battery it would have to be big just to get any run time as well if I went with a UPS for anything over 10 to 15 minutes im looking at over $700. 

My power don’t go out often but darn that was a rude awakening.

I doubt the current draw is 6A.  That is pretty much a worst case scenario estimate at max pressure & heat settings I would bet.  My Respironics at a median pressure of 10 ish runs about 400 milliamps; with heat humidification set at "2", it will draw about a pretty steady 1.0 amp.

OMMOHY

Regardless, it seems it will still cost a grand just to run the thing on battery for the whole night.  WOW.      I guess its better then nothing though,  even for just a surge or short power blip probably not a bad idea.   but 300 dollars is probably only get you a couple hours...   a rude awakening indeed...

I see they have portable battery packs made for specific cpap machines that claim it can go 6-12 hours.   They cost about 300-500 dollars,  but it seems they are meant as travelling packs.  And not really meant everyday use to act as backup surge protector?

RE: Use a UPS for backup with CPAP suggestions
The Medistrom Lithium batteries for CPAP machines run about $400, and are good for at least six hours with very low/no humidity or heat.  If you are looking for a buffer against surges, you want a surge protector, and decent ones can be had for about $40, some with multiple sockets like a power station. I place one of those in the wall and plug my Medistrom battery into that.  We have finally gotten into our stormy time of year with its inevitable power outages.  I have tested my system, and it works, but haven't had the power outage yet in the middle of the night.
