I have dual chargers, so I can't answer your question. (I believe dual chargers only make a difference when supercharging).
For what it's worth, I have a 240v plug for charging at home since I am usually there for 5hrs in a 24hr period.
I have dual chargers and both a nema 14-50 and a HPWC at home. The dual chargers are needed for the HPWC or anything above 50 amps I think. The supercharger bypasses the on board chargers I believe.
The second charger is low cost, so I don't know why somebody wouldn't include it. On resale, I can see a lot of people not considering the car because of the absence of the second charger. If I would buying used, I would not consider a single charger car.
One of the things that I think I am going to like in owning an EV is never having to visit a gas station. So why would I want to go to a Supercharger except when it is necessary? DVP&Lawrence is even between my office and home, but I wouldn't take that route on purpose and I wouldn't want to take the detour and go there and wait 30 mins to get charged. I am cheap too but my time does have value!Looking at the flip side, however, who would want to do AC charging other than overnight once the Supercharger network is more extensive? (And 40A is enough for overnight). At that point the extra charger could just be extra weight that is never used.
Correct. A single charger can handle 40A, 240 VAC and dual chargers handle 80A, 240VAC.
The supercharger completely bypasses the internal charger(s), and so whether you have one or two has no impact on supercharging speed.
The second charger is low cost, so I don't know why somebody wouldn't include it. On resale, I can see a lot of people not considering the car because of the absence of the second charger. If I would buying used, I would not consider a single charger car.
It looks like the Montreal - Windsor corridor will be full of SCs shortly. But once you get off that corridor, Canada is pretty much SC wasteland and will likely be for a while yet. But there are a fair number of 70 Amp Sun Country chargers.
I just want to remind everyone that BC is (still) part of Canada!!
:tongue:
Alberta may be joining us in the land of the debtors with WTI at $55.40.So far.... Eventually you'll all get sick of supporting the bankrupt Ontario government with your transfer payments, and get the good sense to separate! :crying:

True, but again: do you want to do a road trip with 70A charging? It's faster than 40A, but it's still GLACIAL compared to a Supercharger. If it's at 208V, that's typically 200V under load, so 200*70 = 14 kW. Still 3 hours to do what a Supercharger can do in 25 minutes. Two hours driving, 25 minute stop becomes two hours driving, three hour stop. Repeat.
That sucks, if you ask me. It's unlikely that there's three or more hours of really interesting things to do within walking distance of every 70A charger.
To me, the Model S is not a viable long-distance trip car unless you're on the Supercharger network or you're really willing to take your time, and have a lot of patience. And if the car is not used for long-distance travel, there's really no need for dual chargers as 40A is enough for overnight.
You really have to look at how you plan to use the car, and where, before deciding whether it's worth it to you to get the option. If the extra cost is not a big deal, and you like to have the best spec, then just go for it. Otherwise, I'd say it's a waste.
Of course a SC is best. I'm from Sudbury and only decided to buy the car once a SC was announced for Barrie. I agree that 70A charging is impractical for any regular distance travel. But I can see an occasion arising where there was no SC available. I'd rather sit and wait for 3 hours than 6. Do what you want of course. For the negligible cost, I think that the second charger is a little bit of insurance.

I think you are missing the point. If you have a need for faster charging at home you need an HPWC and dual chargers. I got the HPWC for the rare occasion I come home with very little charge and then have to go back out in a short period of time. It's all about the safety factor.Dual Charger is a waste of money. Tesla will have the Chademo chargers available in January which allow you to use the non Tesla charging network with direct DC charging at around 50KW.
THis along with the ever increasing SC network makes the dual charger option a waste of money in my opinion. We already have 2 SC stations between Mtl and Toronto. The Chademo adapter is going to go for around 450$ and will let you charge at 50 KW which is better than the dual charger with 240 Volts.
