After speaking with the Suaoki support and digging deeper into my CPAP machine's stats I"m still going to give the battery backup a few more tests. CPAP should be using only 7 watts per hour per the manufacturer. So, I would think I should be able to get close to 3 nights of use using roughly 45 watts per night. The battery backup claims 150 watts. We'll see, I still might keep it.
As for the generator, I needed one regardless so that is why I pulled the trigger. If I do take it, it will be to top off the house battery for a few hours during the day and keep it off most of the time.

Absolutely -- all Amazon reviews, both positive and negative, must be taken with a grain or two of salt. That's why I said, "
Needless to say, those are just three reviews, but there are 36 "critical" (Amazon's term) reviews. That's 26% of the total."
Any review (good or bad) may not be deserved. Good reviews often go something like this:
"It arrived on time; it's shiny; I like the color; I got a great deal (because other similar items cost much more -- often with good reason); I haven't used it yet but it seems well made..., etc, etc.
Same with bad reviews. It could be, as you suggested, that both CPAP reviewers left out relevant details, like whether the heater was used. That's a good point, and something to attempt to determine. Perhaps some of the positive reviews have more complete information -- like CPAP settings, actual power used, and total run time.
One thing is for sure -- we cannot simply look at the % of 4-5 star vs 1-2 star reviews. It is important to actually read a good number of each and try to determine which ones seem authoritative.
For those who aren't aware -- when purchasing an inverter, it is important to know whether any device you may possibly operate with it requires "pure sine wave" (PSW) power. That is often very difficult to determine. Mfrs do not generally make that info available in their specs. For that reason, we decided to go with a PSW inverter (MS2000) in our rig.
Most appliances and devices can operate OK on modified sine wave (MSW) power, but some cannot -- and the ones that have a problem with MSW are often destroyed by it.
Just something to keep in mind.
