A product I'd like to buy is a big portable electric heater which has a J1772 (or J3400) EV charging connector as its input.
If it pretended to be a car, then I could plug my car charging cable into it and have a 7 kW heater for the garage when I feel like heating it up real quick.

That thing is like 2 cm thick and supposedly more efficient than normal electric heaters.
Quite fascinating.
In the rare in between case, I would be satisfied with waiting for a little while.
But of course everyone has their own definition of luxury 😄
But I feel like it's silly to use a charger for an active appliance. That's why outlets exist.
That's like using a massive USB adapter to power a toaster.
I also wonder about efficiency losses.
But the benefit is I already have that high-powered plug in my garage, and that high-powered plug is meant for many repeated mating cycles.
Have a very distant thumbs up instead.
👍
Much more user-friendly and makes the car charger more useful.
I wonder how large the heating element would need to be in order to put out that much heat while still remaining at a reasonable temperature?

My second post about giving it logic so it can determine how large of a circuit it's on and automatically shut off elements it needs to to stay within spec isn't an offhand idea, it's a thing which could be done.
Seems like a really wasteful idea because you're converting power from standard 220v into the fast charge ac/DC format. Lots of loss that could be heat.
And you could just wire them in parallel with a lockout circuit so you can't use both at once anyway
Charging circuits can be any capacity based on the ampacity, and the charger's main job is to tell the car how many amps it's allowed to pull and energize the cable only when safe and the car requests it.

They could probably get ETL, those guys will list anything. 🤣🧯
"Hey. Here's half a dozen other appliances that like 7kW for your garage."
Or do the regulations require it to be a car?
The big problem is bringing *waves hands* the whole product to market. Even if the idea is simple, it's a niche.
We're talking taking a standard heater product then adding an extra $50 of circuitry and connectors.
A cursory check of my not-so-local hardware store's websites show 10kW heaters are about $600, so a $50 bump isn't really that crazy, especially if it could *also* plug into a standard NEMA connector. Instead of creating a whole new product, add EV charger support as a feature.

"Haha heater go vroom vroom"
Please tell me I'm mistaken!
The website isn't loading for me, so can't check there
The J1772 plug/socket are shielded on both sides, so there's not a significant distinction between male and female sides apart from basic geometry.
I was planning to get one of these for an electric garden tractor conversion I am slowly working on.

10 kW shop heaters are a thing you can buy but they usually need to be permanently installed and hardwired.

I'm not an EE, is the charging circuit in this case a purely resistive load or are there also some reactive qualities?
@hoofurs.bsky.social halp
Switching more or less elements to top out max safe current might be difficult.
Unless using multiple smaller heaters with relays
The only thing it really misses is max current signalling and that could be done by some pins shorted with N conductor.
I can’t actually think of a product that wouldn’t kill people if a determined enough fool got hold of it. 😂
If only there were some YouTube channel that would explain these things.
mmmm, toasty.
That thing doesn't even use a refrigeration cycle!
Where's the heat pump?!?!?
