single charger

I'm contemplating purchasing an older Model S or a newer Model3. Ideally this is an easy question,... go with the 3 but it really comes down to cost for me. I know that with overnight charging I can get a full charge with either a single or dual charger in the car but I'm more or less...

So I may of made an mistake. For the last 3+ years I've been happily using the mobile connector to charge my car. It has worked well and I typically pull 40A at 237V. The car is equipped with the standard single charger. This fully charges the battery during the off-peak evening rates...
