I have been researching extension cords to use for charging my Tesla Model 3 on a now and then basis when staying with family out of town. They only have a 5/15 plug so it is trickle charging (12 amp). I need to use at least a 25 ft. extension cord. Everything I have researched says I need at least a 12 AWG, or a 10 AWG. I have also read that the longer the cord the greater the resistance. What I don't know is if a higher gauge improves the charging in some way (other than just safety)? I did find a 12 AWG, 25 ft. cord, but I couldn't find a 10 AWG, 25 ft cord. The shortest extension cord I can find at 10 AWG is 50 ft. So my question is this: Which will charge faster/better: a 12 AWG, 25 ft cord, or a 10 AWG, 50 ft. cord? Thank you in advance.
