Until the promised supercharger in Merritt is built (was on the Tesla map for 2016 but nothing happened), it is nice to be able to top up an MX in Merritt if going to Vancouver from the interior. There is 12,000′ of climbing between the okanagan and Vancouver and you cannot drive very fast if you only charge in Hope.
My Chademo has saved me twice, once in Merritt and once in Surrey when I had to detour to drop someone off on the way to downtown Vancouver from Kelowna.
I set up a Greenlots account for use with the chargers.
If you do buy one, watch the video online (youtube) as to how to use it since it took me 15 frustrating minutes to figure out the “locked” position so that the charger would work.
