I went with a fairly entry level Model S. 60kWh, Tech Package, nothing else. No dual chargers, no SuperCharger. The reason is simple. 90+% of my driving happens in a 30 mile radius around my house.
But on the occasional odd trip it's nice to know what the options are. SuperChargers are out (not worth the $2k to me). So the best bet should be 40A J1772 or 14-50 stations. They should give me about 25-30 miles per hour. But what about Roadster charging stations with 70A @ 208V. Can I use those (assuming I borrow an adapter - one of the stations on a typical road trip route for me even has an adapter right there with a small 'buy in' to use it)? Will the Model S simply limit this to 40A (which would mean it's slower than a 240V/40A 14-50)? Or will it charge at 46A (240V/40A gives the same amount of power as 208V/46A)? Or will it simply not work without a dual charger?
I'm taking delivery on Friday and am planning the first of those extremely rare road trips for later this month... and while I should be fine (only 160 miles and ability to charge at the destination), I still wonder what the options might be... why be prepared if you can be over-prepared?
