    I see these on sale for anywhere from $250 to $400?

    Do the work?

    Are they legal?

    Any experiences to share?

    $250 to $400 pays for a lot of gasoline. I would pass on this product and just carry the stock EVSE and look for a 120VAC outlet.

    As JB stated, your payback will Never happen.

    I did a calculation awhile ago based on 0.11 cents a kilowatt and ~$150 dollars, that worked out to more than ~5000 miles.

    So if you save your ~$300 dollars, that's like getting ~10,000 plus miles of FREE EV driving.

    PS, If you have a 240v outlet near your Prime, you can charge up in 2 1/2 hours for less than $50 dollars.

    The calculation should be the difference between the cost per mile of gas vs. electric? If you aren’t driving on EV, you are driving on gas, so the savings are the difference, not the cost of electric driving.

    Yep, I'm just basing that on the electric usage itself.

    Just edited that....

    One would have to recurrently charge at a Tesla destination charging station for a long period to recoup the costs. Long before then, management would likely ask such a person to leave unless routinely patronizing the facility.

    Tesla destination charging stations are usually installed to attract higher paying patrons, typically at hotels.

    Using the delta between gas and electric as the savings, for my area of the country (using your same $0.11 / Kwh) at $2.50 for gas (we're a bit lower, but this is conservative):

    Cost per mile to run on electric - 5 miles/Kwh, $0.11 / KWh = 0.11 / 5 = 2.2 cents/mile

    Cost per mile to run on gasoline - $2.50 per gallon / 55 mpg = 4.5 cents/mile.

    Running on electric saves you 2.3 cents/mile if you pay for the electric. To save $300, you would have to travel 13,000 miles solely on electricity provided by that adapter to recoup the cost. That's 522 full charges.

    If you get the power for free from the Tesla point or a hotel, then the savings are the full 4.5 cents/mile and you recoup in 6,700 miles. Still a long time and still 267 full charges.

    That will set sales on fire. Spend $40K plus on a car, get $50 of electricity as a bonus. I wonder if they deliver the car with a partially charged battery pack to recoup the loss?

    With charger version 3 out nearly a year now eveyone should have seen this coming. The news was unsettling at best, but inevitable as lines for charger time are likely to start forming if Model 3 continues to grow it's sales. Even with the new pay as you go program.
    If a model 3 is the right fit as a daily driver, I think the new supercharger fee, although unsettling, isn't even close to a deal breaker in most cases.

    Sorry, I have no idea, but even if it works and legal, I don't think it interests me much. I would have to drive over 100 miles to the nearest Tesla charge station. And what would they charge per kWh for non-Tesla owner even if they do let me use it? I bet it will cost more than buying a half gallon of gas to drive the same distance on EV.
