I think a picture might be easier to describe my unique scenerio. I cannot park where the wooden paneling is as it is tight. My driveway is long so I can park further away with the extension. If I move the outlet outside, then it would need to be attached to the panelling and it would not be great for when I am parking inside. Just trying to find the best solutions given the constraints for indoor and outdoor parking. The 14-50 outlet is on the inside of the garage to the left in the picture. Thanks for the input!Mostly human nature. For one thing, if you use it occasionally, you can check it out each time to make sure it's in good shape. If it's plugged in ALL the time, and used every day, you're going to get in the habit of ignoring it, and likely won't notice a problem until you have a failure of some sort. Since the consequences of failure in a high amperage situation can be so dire, it's not worth it in my eyes. Secondly, having extension cords on the floor can be a trip hazard.
From a "giving advice on the internet" POV, a number of people who want to use an extension cord, also want to do things that really are a problem, like running the cord through a wall, or a propped open door, or across a sidewalk, or using a 14-50 adapter with 14-30 outlet.
As far as your situation, if you want to charge outside, then ideally you would install your EVSE outside. I'm not sure why your situation doesn't "allow" that, but you might want to revisit that assumption. Personally, given your choices, I'd bite the bullet and clear room to park my car inside. If it's a truly short term need, I would do an extension cord, although an entire summer seems like a long time. The longest I've done it is for a couple of weeks when construction at my house blocked garage access.
From a convenience standpoint, I will also say that a long, heavy cord (especially the ones that can handle 50a!) can be a pain in the butt to roll and unroll...and you'll have to do that at least enough to get it back inside the garage while you're not using it.
As for the EVSE Tesla extension cord, is that any safer as a permanent solution than an 14-50 extension cord?
