UPS Battery Backup for CPAP in case of power outage

UPS Battery Backup for CPAP in case of power outage
Which UPS Battery Backup would be good to use with the Resmed AirSense11 in case of power outage? I see from the manual that the unit uses 53W but peak is 73. I’d like a small or medium size battery backup that will give like a few hours run time, and also to provide surge protection for it. I saw a cyber power one in the store but 70W it would run 14 minutes.

I bought a 260Wh portable one from amazon: https://www.amazon.com/dp/B0BKZ5D7XH
Without climate control (humidifier, tube temp off), the battery was at 90% in the morning. With climate control on Auto, the battery remaining charge was 60%.

Thank you for the information. That is an idea. Before I saw your response, I ended up going with the freedom v2 cpap battery. I connected the included power supply to the battery and the battery to the cpap to provide a battery backup

Make sure to test the Freedom 2 as a battery. (unplug it from wall and see if it will power your cpap). I bought one two years ago and used it as a ups. Worked fine to pass power through to my (ResMed) cpap. Had the first power outage a few weeks ago and found that the battery didn't work! It's supposed to switch to powering the unit if no wall power. It doesn't. I held its button to reset it (as manual said), I tried charging it without it being connected to cpap. When plugged it, it shows me it's 100%. Soon as I unplug it, its display no longer lights.
So I have a $300+ piece of junk. Unfortunately, I never thought to test it just as a battery when I first bought it and it's past its 1-year warranty. I'm open to suggestions if anyone knows how to fix it! |
