30KW Tekna (2017)
First, congrats on the purchase. We have a 2016 30 and don't regret it one bit.
I would expect about 80 miles from a leaf 24 although I am not the best person to answer that as i have a 30 and would expect about 100 miles real world driving (again, could be more/less with weather, driving speed etc...) My GOM (guess o meter) usually says just under 130 miles on a full charge if we've only been doing local, short journeys.
As for the charging, you are right, rapids do not need your own cable, they are attached to the charger. Fast changing will often need a type 2 to type 1 cable (the type often found at supermarkets or home installations).
Stuart, to get you 100 miles is that from full to turtle in winter?
What speed do you find you drive at on average to get that?
