I'm getting a Model 3 in the very short term and wondering what extra charging adapters I should consider. Apologies if this question has been asked but I couldn't find a similar thread. The car comes with a 5-15 and a 14-50 adapter. Looking at the additional options there are 6 more adapters. What I would like is the most common 1-2 higher voltage adapters. I'm no expert, but it seems like the 14-50 is the standard "RV" plug, which will come in useful. 5-15 is of course useful in a pinch. Any advice? I'm in Canada as far as electrical standards go. thanks.
