I've driven a 2011 LEAF for 26 months, 15,000 miles, and the only time I ever had the 110V EVSE with me was when I drove to Knoxville. Just in case the Blink DCQC and L2 stations were all broken.
I've only actually used it one time for about 15 minutes in the garage when the Blink L2 EVSE was hung up and not wanting to reboot, and also to make sure the 110 V EVSE worked.
Other than that, I use the eV Project supplied L2 Blink EVSE in the garage. I also used the commercial Blink L2 EVSE quite a bit while working downtown while they were free, and the Blink DCQC while they were free, although the Blink DCQC weren't very reliable until around January of 2013.
The trip to Knoxville was in February 2013. I didn't trust trying it until then.
I still don't trust the reliability to use the LEAF to drive the 90 miles to Knoxville very much. And average speed including charging was 38 mph to get from home to downtown Knoxville, and overall average speed for the day was around 30 mph. Now that Blink DCQC is $5 per session, my cost for the charging is about the same as the cost for gasoline for my ICE for the trip. With the time impact, driving the LEAF to Knoxville doesn't make much sense unless I was staying for at least 3 or 4 days. The LEAF CO2 emissions are a bit lower than the ICE. Although TVA has a lot of hydro power and nuclear and some solar; and coal power has dropped quite a bit with the lowering natural gas prices; the LEAF CO2 emissions are only a bit less than for the ICE.
I also use the still free Highway 153 and Lee Highway Murphy Express Eaton DCQC a lot. This was a first in the nation trial for them. I wish they would all add one. But even though I have done more business with them having the DCQC than I would have if they didn't have it, I'm sure they are losing money by having it, at least for the incremental sales that I have made. Possible that incremental profits from others might be better than mine, but I still doubt incremental sales will be enough to justify providing free DCQC.
