I actually live in Sacramento and the CHAdeMO units I tried with the Nissan Leaf were made by EATON in Vacaville (out of order three times and one time it charged for 15 minutes and stopped due to an EATON system error. Called service number and no answer) and twice at SMUD (Sacramento Municipal Utility District). The one at SMUD had a CHAdeMO on one side and a CCS on the other. The couple times I went to SMUD, the CHAdeMO was out of service, but the CCS was still functional.
Our 2012 Nissan Leaf only had a real world range of 75 miles and we were attempting to drive to San Francisco. This was around 2013 or something like that. At that time, there were only 2 CHAdeMo stations around according to PlugShare - the EATON in Vacaville and Blink at the Hilton in Concord, CA. We stopped in Vacaville thinking we would be there for 30 minutes. The EATON was out of order and we had to use the J1772 to charge in order to get home. Since the Leaf only had a 3.3 kW onboard charger, we had to wait in Vacaville for 4 hrs. Good thing there was a Starbucks on the other side of the freeway we could walk to. Another time, we tried going to Napa and the EATON was again out of order in Vacaville. Each time, we did call the maintenance number that was taped to the side of the EATON EV Quick Charger. Again, we had to wait the 4 hrs at Starbucks in order to get home.
We actually attended the EATON CHAdeMO EV Quick Charger grand opening in Vacaville. It was a nice gathering with the mayor of Vacaville saying the unofficial name of the city was "Voltville". The unit was sponsored by Mitsubishi and there were multiple i-MiEV cars lined up to charge. There were a lot of Leafs and a few Tesla roadsters in attendance as well. A Mitsubishi VP spoke about how the i-MiEV electric cars would change the world.
I'm glad you've had success at using the CHAdeMo units. My personal experience with CHAdeMO has not been great, so we quit trying to take the Leaf to the bay area, and instead drove either the FitEV (no CHAdeMO, but had a 6.6 kW onboard charger) or our 2016 Volt. Eventually, the capacity loss of the Leaf made it just a neighborhood car with a range of about 40 miles on surface streets.
