[Product Review] with PG&E Power cutoff is a remote possibility
#1
with PG&E Power cutoff is a remote possibility
I have purchased this on Amazon. AIMTOM Portable Solar Generator, 42000mAh 155Wh Power Station, Emergency Backup Power Supply with Flashlights, for Camping, Home, CPAP, Travel, Outdoor (110V/ 100W AC Outlet, 3X 12V DC, 3X USB Output)
Suppose to be able to charge from car charger, run on juice for 10 hours, can have a solar attachment (extra purchase) or charge on wall connector. The cost is lower than CPAP chargers but it says on Amazon that many people purchased to specifically for CPAP. 

[Commercial Link Removed] Search Amazon using the above description

I will report on how well it is functioning. The price is only $137.  Sleep-well 
P.S. Heater and humidifier is supposed to be turned off to run on the battery. 
P.P.S. I also bought the solar panels which were more than the generator, $170

If I still lived in CA, I would own a generator...since I live in PA, I'll just by Generac or Coleman stock.

RE: with PG&E Power cutoff is a remote possibility
that's funny. good joke, but in my experience parts of PA (NEPA in particular) lose power every bit as often (and more in most cases) as any other place I've lived, including CA. generators are just as ubiquitous, noisy and obnoxious in PA as everywhere else too! personally, I enjoy the adventure of an outage, for a few days anyway. except for 'sleeping' without my machine, if I can call it that.

RE: with PG&E Power cutoff is a remote possibility
When I did live in CA (Pollock Pines), we lost power for a week due to a blizzard that took down the grid at the 4000 foot elevation. Being without power for a week is no fun if your hot water and cooking are electric (California is in the process of banning gas). It gets worse if you depend on a well and can't pump water, and of course people with medical issues have an essential need. If you need an oxygen generator or ventilator, it is life-threatening. Power outages are serious business and not an adventure when they may recur year after year during periods of high fire risk.

FWIW, propane or NG generators run clean, quiet and are can be amazing for backup power. Where I am currently, power rarely goes out. We have underground utilities and will lose power due to a loss of the grid in the area. I still don't like it much, and if it was common, our house has a gas supply, pad and switch gear. The whole house generator went away with a prior owner, but so far, not missed.

In 26 years I never lost power, even now I am outside of the cut-off zone but one never knows. I am about to install solar panels (in November) but this preemptive cut off is somewhat unnerving (half of the CA population is considering moving out of state). After solar, I will consider a solar battery that now is not cheap enough nor good enough. This portable solar generator is good for camping or trips into areas that lose power more.

The Great State of California is NOT in the process of banning natural gas.  Berkeley was the first city to ban gas IN NEW CONSTRUCTION, possibly looking into the future.  That's a long ways from banning natural gas state-wide.  Back systems are a good idea none the less.

Yet.   Once they finalize their search for a single pink-eyed, blue-backed salamander who's tail-growth has been stunted by 1% due to the greenhouse gas emissions caused by the burning of natural gas, they'll make it a state-wide ban.   Bigwink Too-funny

RE: with PG&E Power cutoff is a remote possibility
Could be a bit light on power requirements.

I can't seem to find any info on the actual power usage of the DreamStation.  But reverse calculating things... If you have 155 Wh available and want to use the DreamStation for 8 hours, the power requirement would be 1.6 amps at 12 volts.

155 Wh ÷ 12 volts ÷ 8 hours = 1.6 amps.

This assumes that the PR brick power supply is 100% efficient and the AIMTOM inverter (it's not really a generator) is 100% efficient too. Neither device is 100% efficient - maybe 80 to 90% efficient at best. Also, the AIMTOM might have a 42,000 mAh capacity when new, but that will decrease with age and number and depth of battery cycles.

So you could bump the 8 hour time down to 6.4 hours to 7.2 hours if maintaining the assumption of 1.6 amps just because of inefficiencies alone.

The current draw of the DreamStation is going to be dependent upon your therapy pressure. Another unknown here in these assumptions.  ResMed has some great power usage info, if you search "ResMed Battery Guide", but I can't seem to find any equivalent info on the PR CPAP machines.

I suppose since you already purchased the AIMTOM, you could run a test and see if/when you have to come up for air, gasping.  If I had to throw darts at a dart board on this one, I'd guess you would be able to run 5 hours on CPAP alone (no heated anything extra), at 12 cmH2O average.  PG&E is planning on many more power outages of unknown time durations.  I don't say this based on what may be coming out in the news but what my nephew says, who works for PG&E.  He's in a different department but is in-the-know.  So don't throw rotten tomatoes at him.

It would be nice to see what your findings are and what your pressure settings are too.  Then go from there.  And if you have to return the AIMTOM to Amazon, sooner that later is better since it is "electronics".  Amazon might be particular about returns on this item if not done immediately.

Please keep us posted.
