I've lost the point of this thread. Is it that folks want to fashion their own charging stations for less than $2200?
Even if you could just buy the 1772 plug on ebay it may not be as simple as making up a cord for it to plug into a dryer outlet. The charger in the car may not engage until it does the signaling handshake with the unit on the wall.
Electrical codes are what they are for good reason. You can think of a lot of ways somebody could be hurt or killed waving an energized plug around.
Once a guy broke in my house and I waived my charging cord at him, he acted like I had a shotgun pointed at him and he bolted out. The primary difference between the box and a cord is that the box is only energized when the cord is in. This is the same as the avcon box which I bypassed by making a pilot circuit with $2.00 in parts from radio shack. The issue with a live cord is droping it in water that is deep enough to cross the contacts,etc. If the circuit is GFI and works with the charger then it should not be an issue. If you have pets that like to chew on things, get the box because a long 240 cord may not agree with your cats mouth, unless you are not a cat person of course.
The point of dryer outlets not being designed to be used repeatedly is true but in the case of of a modified cord it would only be unplugged from the car. If you take it along and use it then it's only occasional use in other outlets. I have three outlets I use, two for EVs and on for a welder, all in the garage and all capable of at least 50A.
Warning- do not do the following as it can be dangerous and even kill you! I also have a cord for emergencies with clap ends I can clamp to panel bindings to get 240 where there is no outlet if I am stuck in a remote place and a dual outlet pigtail that gives me 240 from two 120 outlets on separate circuits.
