A fit EV owner did some Ice Racing and used a generator to charge:
While it is possible to charge from a stand alone generator, it is almost certainly more efficient to use the engine in your PHEV (CT didn't have the BEV available so you almost certainly do not have the Clarity Electric). It will also produce much less pollution than your generator (you seem to appreciate fresh air).
Now this is a good use for a generator. The Fit EV doesn't have much range and has no gas backup.
