Zencar EVSE got back with me. I'll be able to charge off of 120V or 240V and be able to chose between 12A, 16A, 24A or 32A.
Once I get it I'm planning on modifying the EVSE with a 250V 50A twist-lock end so that I can make several removable ends with several different kinds of plugs, including, but not limited to a 120V 15A, a 120V 20A, a 30A and a 240V 30A/40A/50A (by removing the neutral pin) plugs. I'm also going to rig up something to make 240V out of two 120V circuits.
I also have a large 120V isolator. I bet I could use that to make 240V out of two same leg 120V circuits. For an example, at a campground with a 30A and a 20A 120V outlets I could make a 20A 240V circuit.
