Been a while since I've been on here, still happily driving my 2015 Spark EV purchased back in September 2017.
Thanks to a recent $600 stimulus check, I thought I would spend it on a generator for emergency preparedness. Power outages in the Dallas Fort Worth Texas area are uncommon, and I cannot think of one that lasted over 24 hours, but some have been over 8 hours. It's just been something I have wanted for many years but never got around to buying until last month.
One feature that I was hoping the generator would provide is 240V for L2 EV charging capability. At the very least at home, even better if on the road.
After researching, I became increasingly interested in generators capable of using both propane gas canisters and gasoline. If I was to carry the generator and fuel inside the Spark EV, I would be more comfortable carrying something like a propane gas canister.
So I bought a WEN 4750W dual fuel generator rated for 240V 16A featuring a L14-30R connector.
I already have a Duosida L2 16A EVSE with a NEMA 14-50 connector, so got a L14-30R to NEMA 14-50 adapter.
My test charge worked! No tweaks to anything, just connected it all and it worked as I hoped. Generator engine noise changed noticeably due to load when the charging started, but it worked fine during my brief proof of concept test of a few minutes.
Only downsides are that both the WEN generator and Duosida EVSE are not suited for wet outdoor weather. That and I found a prior comment here that the owner's' manual cautions against using a generator to charge.
