Since he is asking for feedback to gauge interest, and since I know many of our forum members would want to respond, I don't think he would mind if I shared his announcement here. As you can see in the photo labels above, his e-mail address is:The Nissan Leaf ships with an 120V 12A portable EVSE for "on the go" charging. I just completed designing and testing an upgrade to it that allows 240V charging while still retaining the 120V capability. This means you can use the supplied EVSE at home without needing to install an (expensive) additional unit and still have a reasonable charge rate. (over 2.8kW) The full safety features including the GFCI protection are still 100% functional, and the unit automatically switches voltage.
We will be offering an upgrade service for these to Leaf owners soon. It would be nice to gauge interest from current and future Leaf owners. Please contact me off-list for more info.
Here's the modified unit charging at 240V 12A:
This shows the new L6-20P 240V/20A NEMA twist-lock installed, along with an adaptor cable so you can still charge at 120V:
