Comment on The "standard" car charger is usually overkill—but your electrician might not know that [32:26]

What kind of range do you have on that? I’ve been debating installing a l2 charger because overnight charging is usually good enough. I tend to get about 15-20 miles range tops on pure electric.

The way I explained it to my brother:

technically just plug in to an existing outlet will work. Even if you didn’t keep up every day, you would get tot the weekend and make it up then

but your garage already has a dryer outlet. Adapters are cheap and it will charge 4-5 times as fast

but 50a level 2 charger is the same size as a stove outlet. Maybe a little longer wire run, and the “outlet” is more expensive, but it’s well worth the cost for the freedom, the flexibility, the convenience … and may even add to your house value

  As explained in the video you can’t run 50 amps ona dryer outlet. It’s 42 amps max.

    Can you cite a time stamp? I don’t want to watch a 30 minute video.
    
    I’m very curious where “42 amps max” comes from, as NEMA outlets are rated for 15A, 20A, 30A, 50A, or 60A. 42A is a rather oddball number; I’d like some context for it.
    
    Most dryer outlets are rated for 30A, NEMA 10-30, or 14-30.

    Not the same person and cba to get a timestamp right now, but it’s the 80% rule - the electrical stuff isn’t designed to deliver the rated amperage continuously for hours on end, so for car charging, you’re apparently supposed to limit it to 80%. Now, 80% of 50 isn’t 42 but 40, so not sure if it’s a case of 80% not being a precise number or a mistake here, but it roughly checks out.

    I believe dryer outlets are typically 30a@240v. That’s a nice step up than a standard outlet and simple math shows 4x the power of 15a@120v
    
    If you have one in your garage, then you already have an outlet that can do faster charging than a standard outlet.

30-35 miles, depending on the season.
