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.

Approximate is 2.5hrs
If you need 8hr...you will need the extra battery plus the solar panel
What ever the dell power supply you got...take that number multiple by 2 and 720 divide by that number is the approximate hrs. As mention by nyc10036 using 65watts.
Dell makes 45watt, 65watt, 90watt, 130 watt and so on...
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.
720Wh ÷ 130W = 5.5 hours
The thing though is that the 65W is to both charge the battery and run the laptop.
Right now, I am looking at a laptop with a fully charged battery.
It is drawing less than 30W measured with a power meter.
If you want to be absolutely certain, I would buy a one River Pro for each laptop.

Thanks!

Otherwise using electricity to provide electricity doesnt quite make sense

Thanks!
The Delta Pro has capacity of 3600Wh and a 3600W (7200W surge) AC output.
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.
Great info you gave for those who didn't know.
AGM's have a few more issues that wet cell batteries don't have, but ya'll can use your own needs to guide your research.
Any way, when I set up my system I went with a 2 battery bank setup. 3 for starting my diesel engine when it's colder than you know what, and a marine bank for deep cycle draws. (Of course, you have to have all the switches and cabling and fusing in place. Fire is a real concern with multiple battery banks.)
Primary reason for my setup was cost and warranty issues. In my area, AGM's cost twice as much as group 31 batteries, and they have a high failure rate. And getting warranty issues settled is near impossible.
Your comment about lithium batteries and solar generators is going to have me spending a lot of time researching this on utube, lol.

I have been specifically looking for something that functions like a Tesla Powerwall, especially for times in locations with the risk of frequent power outages, but without the large startup cost. Clean energy is my preference, as opposed to a gas-powered generator. Probably not the best solution out there for "living off of the grid," but technology is getting us to a better point of making this more of a reality. Will require a power transfer switch next to the main circuit breaker panel. (I don't currently have solar installed and am less interested with the potential increases in solar infrastructure bill proposals in California.)
Perhaps as a helpful comparison, I have been considering the Tesla Powerwall. The current version is spec'ed to have 13.5kWh accessible at around $10,500, before installation, permitting, and other accessory parts. Plus, Tesla no longer sells this without bundling with Tesla solar. There are other brands that sell battery backups for the home these days, but I trust Tesla for the battery cells at the moment.
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.

As an added benefit, the Delta Pro unit has been tested to be able to charge an EV car at a near Level 2 charging rate (Tesla charging at ~30A in the case of the YouTube video - https://www.youtube.com/watch?v=dT7cANo
Check the video (~10:25) for a demo on using 2 EcoFlow Delta Pro units in series to power a small warehouse/facility.

Next best price I can find for the EcoFlow Delta Pro is at HSN.com for $3,300, and most other stores sell for the list price of $3,600.
ie. My utility's TOU plan is $0.11/kWh overnight and $0.56/kWh during peak day 2-9pm.
Even with just 10kWH total battery capacity, that's $4.50/day savings, or $1,642/year saved (assuming one uses all that electricity during peak hours).
