Charging with long extension cord

[OttoT3]

Hi everyone!

I have a question about charging my model 3 with an extension cord the car is located around 80 feet away of the only 20amp outlet. Therefore I got a 100 feet long extension cord. The cord is a yellow jacket 300V 3x5.26 mm2 (10AWG) I hope someone can give me some advise if this is safe before I plug it in to the car with the 20amp Tesla adaptor. Thanks in advance!

I use a 75 foot, 10 AWG extension cord at my kids using a 15A adapter (12A limit) with no issue. I would think a 20A adapter (16A limit) would work also.

You'll be fine. The 20amp adapter only draws 16 amps, and on a 10 gauge extension cord you'll be fine. You'll see approximately a 1.5% voltage drop, which is great.

You are fine to do this.

You will have 2.7% voltage drop which is fine. 5% is considered the max.
