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.

For information and with all due respect, relying on the battery as a UPS solution is not optimal. I initially did the same thing with my ECOFLOW River 2 Pro and this is what happened: There were never power outages and the CPAP drew on the grid. After several months of non use, the battery, which had been fully charged, totally lost its retaining capacity because it had not been cycled regularly.

ECOFLOW sent me a replacement. Aware of this problem, I put a programmable timer switch (EUR 18) between the Ecoflow and the mains. It comes on once a week Sunday afternoon.

My CPAP (no heater, no humidifier, 9cm H2O pressure) runs via the 12V cigarette lighter port cable plugged directly into the 12V cigarette lighter port of the Ecoflow.

Ecoflow powers the CPAP for one week. The following Sunday, the timer comes on to recharge the battery.

Hence, the battery charge / discharge cycle is one week, thus maintaining battery health. I program the Ecoflow to charge max 90% and cutoff at 10% to avoid battery strain.

I may be getting a Resmed 11 in the near future. This machine operates on 24V and the Ecoflow provides 12V. I therefore will need to get a proprietary 12v to 24v CONVERTER (not to be confused with inverter). The ineffeciency arising from the convertor is not excessive and within acceptable parameters (eg: weekly battery charge suffices). As the whole resides on a night stand with drawers and bottom cutouts for cables and hose, there is not excessive visual / cable clutter. Daytime, drawers are closed and nothing is apparent except for the Ecoflow under the nightstand.

Should there be long power outages, I am assured to have several days to maintain operational autonomy and seek power (hello covid lockdowns).

It is good to know a cheap solar panel can ensure the battery is constantly charged but at present I do not deem this necessary.

PS: as my health provider updates masks / hoses at yearly intervals, I carefully clean the old ones and put them in ziploc bags as a reserve.

If you're using the 12V DC adapter, then your CPAP was not bypassing the battery and drawing from the grid. That feature only works when using AC devices through 120V. Using the DC ports continuously charges/discharges the battery.

And using your Ecoflow as an EPS (via 120) doesn't remove the need to occasionally cycle the battery, which is recommended every 3 months. Not weekly as your doing.

After several months of non use, the battery, which had been fully charged, totally lost its retaining capacity because it had not been cycled regularly.

Your battery had a defect. Not cycling after "several" months would not cause a complete failure, especially give the maintenance requirement is 3 months.
