I would recommend getting a low-gauge (iirc 10 or 12 gauge, 25ft max) extension cord. You can't always park this close to places you are staying.
I will repeat again, 10 or 12 gauge, 25ft max. Do NOT use a higher gauge and be careful with longer cords unless it's really high quality. You get what you pay for.
I didn't realize you were L2 charging lmfao. Usually I just L1 from a 120v when I'm on vacation. If you're rich, and can afford a nice #8, that'd be pretty sick.
Lower gauge = thicker wires = can handle more power
The magic term is "contractor cord"
But above all, never pull more than 12 amps from a regular household outlet. Most of them are only designed to deliver 15 amps. Even at 12 you risk tripping the circuit breaker.
I don't know about other EVs but in my Model Y I can set how many amps my car will attempt to charge with. For most people, or if you're unsure, I'd recommend setting it to 12 even if you can go higher.
