That was the first day I had the car, but I can confirm that my statement wasn't even an exaggeration. It wasn't an official Tesla charger though. It was a "Greenspot" charger down the street from me, the closest public charger by far (thus the most convenient, so I was testing it and hoping it worked well). And yes, it was an hour to charge 10% and cost $4.50 or so.
That was just a trial run to see if those chargers were any good. Once I determined that the chargers were in fact dogshit, I found the nearest Tesla Supercharger and filled up there. $27 to go from about 10% to 100%, took about 45 minutes.
I'm still disappointed, because $27 is about what my previous car cost to fill up at around $3.20/gallon. So I'm paying the same amount (probably more, factoring in that a tank doesn't go as far now) to fill up, only with an additional substantial wait. This was with the fast charger too. I've definitely spent more on electric power over the past week than I did on gas in the average week with my old car.
Been looking for a slow charger that's free, where I can plug in for a few hours while I run errands and get some energy back without breaking the bank, but so far the only free chargers I've found have been in private guarded lots like hotel parking.
The Sentry Mode, which unfortunately has to be kept on these days, drains the battery quick too. I found that closing the app out completely when the car isn't in use helps slow down the "idle drain" due to not running any extra processes, but I'm not sure if Sentry Mode stays on when I do that.
