I also rescued one of these "portable battery boxes" from a scooter
that I scrapped (note the "handle" on the black box located under
the seat)
<https://www.jazzy-electric-wheelchairs.com/cache/1509733338387/resources/product/2390/picture.jpg>
Mine is the "extended duty" version -- taller to support larger
batteries.
It holds a pair of 12V batteries wired in series (for the scooter).
I've had to add a connector to access power from the top side
of the case (the existing case has a connector on its underside
to mate with the scooter).

That's considerably "beefier" than what I have. Mine is really small...
weighs maybe 3-4 pounds? I think it is limited to ~100W at 120VAC
(so, when powering a ~6-13W LED lamp, is good for several hours).
It has a USB output as well as a 12VDC outlet/inlet (in the form
of a "(cigarette) lighter" socket). For me, it has utility as
another 12VDC power source for the portable bits of kit (radio,
comms, etc.) that I keep in my bug-out-bag.
[I have another device that is little more than a battery-in-a-bag
that also finds use -- even as an add-on power reserve for the
little inverter]
I also keep a 1KW inverter in the car that will run off it's
battery, in a jam. But, have nothing that needs that sort of
power (at least, nothing that I'd want to lug with me in case
of an emergency)

If it is like the unit that I have, it can be charged from a wall-wart.
Think of it as a "generator" with a very limited "fuel supply".
I use mine to power a 60W-equivalent light fixture during outages;
I can carry it to any light fixture in the house.
Of course, it's also good to stuff in a bug-out-bag, knapsack, etc.

It is almost misleading withthe word Generator. I think it does have
solar cells for charging, but they would take a long time and not at all
in the night.
I would think that genertor would mean a useful generaor that would be
gas or propane powered.

This one has 300W but IME such small inverters trip off all the time
because most power tools have a much larger start-up power draw. That is
one of the advantages of direct DC, no trip-off.
Even regular draw at 120VAC is higher than that. My hedge trimmer and
the weed whacker are the most used tools here and they each pulls 4 amps
at 120VAC, almost 500W. On 50V DC that drops to about half yet the power
is still reasonably ok. Not for a professional gardener but for me.

Not sure about Tesla. Might void warranty. But i have a 2kW inverter on my Leaf (without warranty anyway). I also have a few hundred 18650 buffers as well. I can run my circular saw and drill without problem.
The new USB-C 2.1 (48V 5A) will also be able to charge my Leaf, or at least the buffer batteries.

Since I prefer not to add such "added value" to my stuff I won't buy
such vehicles. Ours are both standard fare and you can get in there. The
upside is that they also contain close to the "legal minimum" in
electronics or other fluff and, therefore, we had no breakdowns in the
more than two decades we own them.
