I’ve used mine to go down the coast line of western USA. Now that they are putting in Supercharging along that route I may only use it on a rare occasion where destination charging may be an issue (or as a backup to it). I think its more of a comfort level for me now to have it.
Also you are able to get back on the road much quicker if you can’t charge overnight or don’t want to wait long at the Supercharging when going to a destination if you can do a 30 minute charge in the destination city.
BC Hydro is expanding DCFC around the province, so it may become more useful to get further around BC. So if you do travel lots in BC then it will become valuable in the medium term too.
