Powerwalls aren't a business' core product, so they're priced at "how much to make it worth our time".

Powerwall should still benefit from the economies of scale being put into Tesla cars and their battery plants. It’s a fair question why a truck would still be competitive.

but again, they don't actually want to sell powerwalls, they want to sell cars, they're just willing to sell powerwalls.

There are a bunch of companies selling powerall type stuff as their core product. Ecoflow, Bluetti, etc.

Powerwalls are both a niche and premium product, provided by basically one company, EVs are neither.

There are probably more companies making powerwall type products than there are car companies. For example, emergency power generation companies like Generac have them, there's an ecosystem of companies competing with Jackery that are attacking it from the bottom (ecoflow, bluetti, etc), a lot of solar and solar-adjacent companies have one (enphase, myenergi, etc).

I doubt what you said is true but irrespective, number of companies != size of market, and the companies you mention serve different markets/functions, so a consumer product company also != an EV company. It is relatively easy to design/build/sell a functional powerwall or generator equivalent, but one person cannot get into the market with an EV.

Your last statement is the reason why mine is true. I'm not trying to imply that the average powerwall company is comparable to an EV company.

Then isn’t it also the reason why your statement isn’t relevant to the point I was making?

Your original statement was "Powerwalls are both a niche and premium product, provided by basically one company, "

Tesla has a very small fraction of this market. Most of the market is outside the US, and Tesla basically only operates in the US for power walls.
