Consider the Zencar 32A EVSE, as it can be ordered with a 14-30 or 14-50 plug. Also, because multiple amperage settings are possible, you can charge at 24A (or even 26A).
Search these forums for "Zencar" - there's lot of existing info.
If you decide to purchase a different EVSE, you'll likely need to choose a 20A model as 30A is too high for the 14-30 circuit.
