What in the world difference does it make whether the charger is listed at 120 or 150 kW??? If you charge much at all, you soon find that having another car pairing with you, or having a hot day, can cut your kW to closer to 30 kW. Most places will not give you more than maybe 105 kW, max, and that's only if you're not paired.
And what's your hurry? After you drive off the freeway and find the SC, you realize that since it's 5PM all the locals are off work and are trying to get a full charge (Really, folks??!!) and there are no free chargers at all. Head on around to the back of the line and wait an hour. Doesn't matter if you're on a trip. Three of the chargers are blocked as their owners are over at the restaurant and are NOT coming back to move their cars. Another charger has been down two weeks and still isn't fixed. Sure, Elon says he's going to charge owners for anything over 90%, but you know that won't deter anybody. They've got free parking! And they'll just tell Tesla that they weren't gone that long.
The smart travelers charge in the middle of the day, Mon-Fri, and "never on a Sunday" as that's when the locals are all trying to get a free charge for the week. I mean, charging at home costs, what, maybe ten cents a Kw? Shoot, that would be near ten dollars for a fill up! Or less!
So, charge to full at home, and only use SC enough to get to your destination (what a concept!) where you can charge overnight enough to get back.
I wish all the newbies could figure this out. Superchargers are for TRAVEL ONLY. Get an electrician to add an outlet to your garage and charge at night. Quit having to fight the hassle at the SCs and leave them for people who really need them to get to their next stop.
Wouldn't hurt if Tesla would insist on raising the price of your car $2000, to be returned when you can show proof that you have the outlet.
