I try to explain to people on our local forum here that one of the most important things about an EV is it's ability to charge as fast as possible.
I have the 6.6 Kw charger and I would not own an EV with less, sure the 3.3 does me 98 % of the time to charge up from Midnight when the cheap rate kicks in until about 7am when I leave for work, or visa versa when I'm working nights 7 pm leave the house.
Check out our charging infrastructure

Use the filter on the top of the map and select standard type 2, they're the AC points all 22 Kw then the blue are the DC chargers and the yellow are hotel/other.
So we got a decent infrastructure and it makes sense to use it to the full !
The 6.6 Kw charger has meant that on many occasions I have been able to get back to the car, unplug and drive off without having to look for a DC charger and then also have to wait for it to charge or quiet possibly have to queue even before I start to charge.
A few weeks ago I plugged into an AC point at 25% and 2 hrs 20 mins later it was 100% charged, so quiet possibly would have got from 25% to 90% in 2 hrs. The last 10% takes longer but I think the 6.6 Kw charger is quiet useful and should be standard and shame on Nissan for making it a 900 Euro/1000 Dollar ? extra !!!
The Renault Zoe with it's on board 2-44 Kw AC charger is quiet fantastic and will charge from those AC points here in 1 hr to 80% or 1.30 mins to 100% from 0%. It would be really good if Leaf II had a 20 Kw AC charger, with all the AC points going up world wide it would be a real shame to ignore AC charging especially as batteries will get much larger.
