20' Deco Home Level 2 240V 40A NEMA 14-50 Wall EV Charger w/ Tesla Adapter Expired

Probably not.
Unlike EV charging, range/dryer only need to work like 1 hour each time. Also, most likely they will not operate on their maximum power. So not an issue for comsumer grade NEMA outlet.

EV charging is consistent maximum power draw until charge finishes, which could be the whole night.

Do companies "counterfeit" that they are UL certified or put on counterfeit UL certification stickers?

Is there a UL website that you can look up products to confirm they actually do have UL certification?

So many counterfeit products out there these days, I wouldn't be surprised if companies print counterfeit UL stickers and stick them on the product and then claim to be UL certified.

Garbage, do not buy. Stopped charging at full speed, now giving like 16A only on 240v

People are confused as to what these actually do. These are basically power cords with a few safety cut outs. These "chargers" have no means to control the charge rate. The charge rate is controlled by the vehicle's integrated charge controller. The logic that sets the actual charge rate is complicated and varies from manufacturer to manufacturer. They take into account things like battery temperature, charge socket temperature, battery charge level, other heating/cooling system loads, etc..

Might be cheaper not to get this unit that has a plug. Get a unit that is hardwired (no plug). The direct hardwired units only need 2 hots and a ground (and you can even use EMT conduit as the ground). Also, doesn't need expensive industrial receptacle.

I have a 50 foot run between panel and 48 amp charger. I ran 2 hot runs of #4 THHN 90C wire. Then ran it in 3/4" EMT that can be used as the ground. For extra safety, also have a #10 ground wire in the conduit running back to panel (in case of EMT break or section separation). Don't need a neutral, and don't need a ground wire with metal EMT (optional smaller gauge ground wire can be used for extra safety).

The charger might cost a bit more, but you will make up the savings in wire and materials cost. Also, if you are running four #4 wires with this plug in model, you then have to go with 1" EMT, which is basically going to be impossible to bend with a manual pipe bender, you will need a hydraulic pipe bender. I was able to bend the 3/4 EMT with a manual pipe bender, but it's really hard and I even had a helper. Only need 3/4 EMT with a hardwired unit, due to less wires in the pipe. Don't overstuff the wire in the pipe, use a conduit online pipe sizer calculator to determine pipe size. If you overstuff the pipe, the wire will overheat.

I think this plug in model is good if you are mounting it right next to your service panel, like a couple feet away. But if you going to have a run more than about 25 feet, I would go direct hardware. It will actually be cheaper overall, due to less installation materials cost.

And people who own ICE vehicles should only be allowed to get gas at an oil field?

Got the plug in version - Plugged this into a 15 amp outlet - worked just fine. After a few days, took it to a friend that has a 14-50 outlet, unit has four red flashes indicating a ground fault. Friend uses his mobile Tesla connector plugged into the outlet just fine. I have not tried with the NO grounding setting in the unit, but 15-50 should outlet should have grounding. Am I missing something?

I would get the cheaper/portable version. It's about 1/2 price of Tesla, except that you have to use an adapter
Edit: Bought one as I need to return my current Tesla charger with my lease return. $116 delivered is awesome (compared to $266 for Tesla)

Update: got the unit. It gets hot and is not UL certified despite claims in the description. It's going back and I will use a Tesla adapter only.

What "got hot"? All these things are is a relay controller, there is no power conversion.
