Not only do I understand, I know that a UPS makes much more noise than a jump starter which is silent. Silent is what I prefer when sleeping.

I have used a jump starter for full night and for more than one night. Certainly you already know that the health and size of the battery directly affect how long it will last at a given pressure. So I can only think that your battery was too small, not charged, or old and on its way out, all of which will also affect the duration of a UPS under a load during an outage. I have seen them fail within minutes.

I have several rather large UPSs and went with a jumpstarter with an 18ah battery which as mentioned lasted the nite and into the next nite. Depending on many things including the set pressure it would be wise to have more than one if you hope to last more than one day but the above UPS is not expected to last more than a couple hours. If that is acceptable then all is good. I would certainly give it a try before the power goes out to see how long it will last and how you like it (the noise of the inverter). Some have fans and many you can hear before they are under a load when the lights go out.

Personally, I am prepared for much more than that since even where the power doesn't go out often you can't be sure when it will be restored once it goes out.

On several occasions I was able to sleep thru (w/o interrupting my sleep) brief outages when using a jump starter. Then there were times when I would wake up as soon as the power went out. But I was able to go right back to sleep since there is nothing else to do when the power is out, so in that respect it is like using a UPS.

UPSs have the very same problems.

Thanks guys, Interesting thread. I only bought up the topic because I have a spare UPS.
What im going to do is hook it up to a spare cpap and set a timer with it running and see how many hours I get out of it.

Since outages here are nearly always under 1 hour I think it will be a good solution

My UPS is silent. Some have a hum, some have a fan. Reviews are handy,

Good for you. Most of the time my use is about 20 Amp-hours a night so 18 AH would not go a night. Last night, however, I only used 4 AH. I'm sure there are some people that use 30 AH a night. Most power outages are short, some can last a week. The world is filled with different possibilities, different solutions,

If you have a solution that works for you, that's great. My personal solution, which is my primary recommendation, is a 35 AH battery, with a BatteryTender. Others may have different needs, others may already own a UPS. If this works, there's no problem with it.

You are absolutely right. I thought you would never realize that much less admit it but then you prob won't repeat that statement.

That is not what you have said your measurements recorded for your use in earlier posts and that seems very extreme for your pressure.

But finally we agree

I don't understand what you're claiming. I've said many times that my pump uses 4 Amp-hours a night, and that's in line with numerous other reports. My usage report also has several nights with humidity 3 and heated hose for a total of 20 Amp-hours, also in line with other reports. This is my normal setting most of the year. Philips doesn't publish numbers but the ResMed A10 series at pressure 10 with heated hose and humidifier (set to auto) uses 23 Amp-hours a night, according to the ResMed battery guide.

Perhaps you're confused with the concept of "pump alone" versus "pump with heated hose and humidifier."

Not at all its the double talk that is confusing.

And then on one of the most humid nights of the summer in your area you want to say that you used the humidifier? On 3? You want me to believe that or this?

Kinda convenient I think for the sake of argument. Just make it up as you go.
BTW it was you who brought up a jump starter then bashed it.

I can quote double-talks all nite instead Just help the OP solve his problem instead of confusing him.

If a UPS solves your dilemma then use it. I only suggest you try it first to make sure it will satisfy your need and you have some idea how long it will last.

Just to summarize after testing the machine ran for 90 mins on the UPS which should see me through 99% of blackouts

The unit is locally made and costs $70 US and for the money it does appear to be the ideal solution
