I completely spoiled myself. I will tell you what I have and you can work your way out from there according to what you can afford or what is logical for you.

I use a sweet battery backup called an Ecoflow Delta2. Right now on Amazon it is $499 after the $200 coupon. Original price ranged from 700-1000. You can plug this into the wall and plug the pap into it and when power goes it it doesnt miss a beat or stop working at all. https://www.amazon.com/EF-ECOFLOW-Porta ... hdGY&psc=1
'

I too have an AS 11. By plugging a special cable into my battery bank, I use the DC adapter to maximize the number of hours I will get. There is a "barrel connector" like you use in your car for your mobile charging. I use this cable (edited to update with actual AS11 manufacturers cable). https://www.thecpapshop.com/resmed-dc-c ... gLmYvD_BwE

The DC adapter is great for maximizing the number of hours you will get. If power goes out, I will switch from my regular AC plug to the DC adapter to extend the usage.

From there, the biggest draw on power is your heat and humidity levels. I can't sleep without as comfortably as with but if you cut them out completely you will double or triple the hours you will get from this bad boy. As a compromise, I have set my comfort settings down a notch on heat and humidity to cut the power usage and get used to using less. If it was a longer term storm I might cut them completely depending on when I could get out to recharge.

The whole thing can be charged in just about an hour on a regular power outlet on highest speed charging. I went all out and bought a solar panel as well to charge it.

If you can't manage something like this, they make smaller power banks that might suffice for a shorter term if you needed SOMETHING but be aware that with heat and humidity some of them may not get you through a full night of sleep..

We could get into greater specifics and discussions about the advantages of lithium iron phosphate (stable, not explosive, lasts several times longer overall) vs lithium ion (like your phone and electric cars, which can explode) vs lead batteries (which release lead gasses.)

Hope this helps.

Please let me just add-do not accidentally buy the Delta2 extra battery. It has no plugs on it.

The Delta 3 plus looks even sweeter. https://www.amazon.com/EF-ECOFLOW-Porta ... F0aWM&th=1

I just want to chime in to re-enforce exactly what lynninnj says.

I use the exact same battery, Ecoflow Delta 2.

I keep the battery plugged in to AC 100% of the time, and then the CPAP plugged in via the AC inverter. The advantage of this is:
  • The CPAP is drawing of the grid and not the battery, there for there is no charging cycles against your battery
  • Should an outage occur, no problem, this Emergency Power Standy EPS mode switches from the grid to the inverter in less than 30ms therefore you will sleep right through it.
    How many people have high capacity batteries, but when a failure occurs, they need to stumble around and hook it all up.
  • If their is an outage, then I'll use my DC-DC converter for more efficient draw
Avoid Computer UPS, they have poor capacity, are overly expensive and constantly draw off the battery, therefore have a much reduced life.

The EcoFlow Delta 2 is the best of both worlds.

Just the other night the power mustve gone out for a period of time. I got text messages from power co to say when power would be restored etc. The clock was blinking on the oven when I got up. I had no idea that power went out because my machines let me sleep right through it.
