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 bought a dual fuel inverter generator a couple years ago and ran it for several days on propane last summer during a blackout. Then I got the River Pro with extra battery a few months ago mainly for indoor/winter use during blackout. I also have 10 or so UPS around the house to maintain my network drives, routers, hubs, and some home automation devices.
Does your totally portable power supply charge from solar and 12V car port?
The River Pro $430 for 720Wh.
I have 100 watt panels on my other unit but a 100 watt panel is not what I consider portable. A 30 watt mono panel is about right for something you carry over and set up in 5 seconds.

Without solar assistance, none of these battery boxes will keep you going for long with anything of substance on them.

LOL.
I have no idea what makes you think your unit is that great. LOL.

I think that someone like you really should buy one of these. I recommend it for your purpose of charging a smart phone and tablet. The 600 watt outlet should be enough for a modem and router, but just barely. Good Luck to you.
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.
It's a 55 Ah AGM deep cycle battery with fan cooled DC-AC inverter and DC to DC.
It comes with 2 USB, 2 12v outlets, 2 AC outlets (which need fan cooled inverter to run), and rear connections for additional solar panel or additional AGM battery.
The unit has a pullout handle with large wheels to move around because it weighs 100 pounds.
It comes with 5 folded solar panels that can charge it 35% on the best sunny day. Of course the inbuilt solar panel is just for worst case scenario to charge small electronics via USB, or an LED lightbulb during multiple days without power.
It recharges with an AC adapter in about 8-10 hours if it's drained. It has an LED voltmeter display. Inverter will automatically shutdown when voltage drops below a certain point to prevent damage.
It can also be recharged in automobiles using the 12v outlet.
I've used it to power a 55" TV to check news, run microwave oven, power the natural gas cooking range for the starter, charge phones and laptops, power the modem and router, during power outages. I've had it for almost 9 years for peace of mind. I have to recharge it for about 15-30 minutes every few months to top it off.
For apartments these things are great because there is no noise, no exhaust fumes, no maintenance, and multiple ways to recharge them.
