Good backup battery “solar generators” are great.
I recommend the Pure Sine Wave versions that advertise an ability to run
in UPS mode. You can leave them plugged into the wall to keep them charged,
while using them at below the UPS wattage limit, and Pure Sine Wave AC
inverters provide the cleanest power along with properly efficient duty cycles.
300-500 watt hour LiFePo4 units with 300 or 500 watt pure sine wave
inverters ought to run most CPAP machines for many hours, and have the
advantage of being car travel friendly.
For general home use, something bigger is handy.
I like these for their up to 1100 watt UPS functionality, 2000 watt hour
LiFePo4 battery, 2000W continuous(4000W peak) Pure Sine wave
Inverter, 100 watt Type C PD ports, 2 hour recharge time on AC power
and 500 watt 48 volt solar input rating. Runs and recharges all the small
stuff and can still keep the freezer frozen all day. It has two solid handles,
but it’s almost 50 pounds. Dad and I put ours on small dolly’s.
I’ve tested mine, boiling water with a 1500 watt portable induction cooktop
plugged into it while unplugged from AC power. No problems.
Curious how it would behave when exceeding the UPS operating limit of 1100
watts while plugged into the wall outlet, the generator shut itself down shortly
after getting the cooktop up over 1200 watts. Resetting the generator involved
turning everything off, unplugging everything, plugging the unit back in and
turning it back on. UPS mode had no problem working an 800 watt portable
coffee maker and a laptop at the same time. (Or boiling water at 1100 watts on
the variable power induction cooktop.)
Pro Tip: UPS capable Units like these with kilowatt hour and larger batteries
can also serve as VERY long running uninterruptible power supplies for home
networks, security cameras, video doorbells, etc.

I have friends that haven’t pulled the trigger yet if anyone has other options to suggest.

Thanks.
Thanks I will be ordering this item to replace my 2-3 year old RockPal for my Cpap
BLUETTI Portable Power Station EB3A, 268Wh LiFePO4 Battery Backup w/ 2 600W (1200W Surge) AC Outlets, Recharge from 0-80% in 30 Min., Solar Generator for Outdoor Camping (Solar Panel Optional)
Hopefully, my Rockpal 60 W Solar panel will work. I don’t care if it take 8 hours.
Thanks again for an excellent suggestion/alternative.

Thanks for the info on the Bluetti EB3A. I just ordered one from Amazon at a good price:
50$ off of the $300 and some other minor discounts and my $’s back for a $226/total to my door. It will arrive on Wed or Thu of this week.
