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.

All that being said, which of these is good for fridge and cell phone power. I can live without the rest during an outage
Not a full replacement for my current 3000w gas powered inverter generator.
Still, it would be nice to have instant-on, and no generator noise
And it could be placed in the kitchen to run extension cords.
Wonder how much the large and medium units weigh.
This one says it will run a hairdryer for 2 hours. I would not consider this a reliable backup power source alone.
Space heaters, toasters, microwaves, and hairdryers are the only things that have ever tripped a breaker in my house under normal use.

If an average household uses 30-50 miles per day, at the average rate of 3-4mi/kWh (non-freeway) for EVs these days, someone will only need to charge 8-10 hours at 1600W with the EcoFlow solar system. Of course, this assumes there are 8-10 hours of good sunlight while the car is parked at home.
Seriously, just because you can do something doesn't mean you should
I don't really get off how these guys charge this much for this. Batteries are well under $200/kWh but this thing holds a whopping 3.6kWh and it's nearly $3k!? Obviously it's got the inverter and some other costs in it but it seems like their margin must be insanely high on this.

If you're thinking about these over a generator, these are not comparable unless you're using very little power or using multiple in various locations around the house.
For perspective, 1 pack would power an oven for 2 hours.
I have used 3 of these in mini home off grid situations, they work great to power a mini split, fridge, maybe the washer/dryer, and outlets for a few days. These are super plug and play when adding solar or other power sources.
I use 2 of these to run a camper A/C in overnight hours to avoid the noise of an engine.
