With the Tesla pricing, that's about $778/kWh (without taxes, installation, circuitry, etc), and the Powerwall is not portable, if that matters to some of us.
With the EcoFlow pricing, it's $791/kWh (without taxes and still need something like a power transfer switch installed) at the Costco price or $1,000/kWh (at the EcoFlow retail price of $3,600) and $750/kWh for the extension batteries (at the EcoFlow retail price of $2,699).
I consider the EcoFlow Delta Pro model as a DIY (as someone else has put it) starter version of a home battery backup system, with some other benefits, such as having clean energy for camping and other peripheral uses. To have it fully able to be a home backup system for a decent amount of time (12-24 hours), I will probably need 4 of these linked in series, which might be the max at this point in time. With ~14kWh, that should be more than enough for my essential needs, if I turn off non-essentials. (I'm using around 6-8kWh for essentials per day and about 12-14kWh for a typical day that includes non-essentials, too. This is in San Francisco, so no A/C.)
The Delta Pro can power essential things for at least a few hours in a serious pinch.

I'm looking for a power source to power my 90w CPAP while camping for a few days (90w x 8hrs x 2days = 1,440 watts). Would this be considered a good price for a portable power source?
No, you can't charge an EV on 600w. It won't work.
And yeah, you'll get maybe 2 miles from this pack if you somehow found a way to do it.
Not sure why this was brought up, or why so many people are considering this.

I would still worry they wouldn't work at all, since my 110v charger wouldn't work off a generator either. It had something to do with the ground detection. So probably not useful even in an emergency.

I built my own battery bank with a costco AGM, inside a battery box and with 12v and USB outlets (I can connect an inverter to the terminals I put on top), and in the end it cost me almost as much as an equivalent lithium solar generator (watt for watt) would be. However, I can charge it much faster from my alternator (it serves as a 2nd battery for my jeep, and is tied to the alternator with some 4 gauge cable and quick connects), and it will let me do 24V welding when connected in series to my starting battery. I can't find a solar generator that will let me pull 160A of power thru a 12V connection, which is why I haven't gone with one yet. I'm planning on building a lithium battery bank wired in 36V once costs come down some more, with the ability to also output 12V by either flipping a switch or with a DC to DC downconverter, so I can basically build my own solar generator that also lets me trail weld at 36V.
The solar panel is trash! Soooo difficult to set up. I'm guessing all of the Ecoflow panels are just as annoying. I had a Jackery Chinese clone panel that I got an $8 mc4 adapter for that works soooo much easier. Going to sell the Ecoflow panel. I'd suggest not getting that combo.
