It may be a requirement to only have a J1772 charge port. AFAIK the only vehicle that has both J1772 and a standard 110v charge port is the 2011-2012 Zeros, and that's with an aftermarket upgrade.
Every other J1772 vehicle - MiEV, Volt, Leaf, Coda (afaik) .. use a J1772 to 110v adapter.
It seems like the Empulse does as well. It may be a little bulky to carry with you.. will see.
