I would just not buy it.
I've seen $20 milk for sale on a remote bahamas island. If someone really wanted milk, they could get it. That is the beauty of the capitalist system. If the seller starts making a lot of sales (and profit), competition will jump in - driving down the price.
Yes of course. But, have you ever not bought something and also informed the seller that they were way out of line? This happens on forums all the time. Someone is selling something, the price is way out of line, and people are happy to let them know about it.
This case is different, because my girlfriend drives a Tesla and has booked the Airbnb for a future date—and that is why I'm involved. I've continued to help the owner over the last few days. His tone has become much friendlier as he realizes I'm really just trying to help him. He's ordered a Chargepoint EVSE that I recommended (plug-in or hard-wired options) which will work for his existing NEMA 14-50 outlet....which is upside-down. This is another thing he didn't know even though he had it professionally installed.
There was no EVSE mounted on the wall that would benefit from an upside-down NEMA 14-50 installation so it was likely just installer error. The NEMA 14-50 top hole looks a lot like the 'ground' hole in a normal outlet. The installer has probably been installing these upside-down for a while now. Should be an easy fix though.
The J1772 connector can be used by pretty much every EV driver who'd want to rent this unit, so it's the much better option all around. No need for drivers to provide their own cables or adapters, assuming they even have 'em. If it were me as the Airbnb owner I'd want to know about my mistakes as soon as possible and would welcome any corrections/feedback.
You're not wrong that the market will correct this behavior, maybe, but this creates a mystery to be solved by the Airbnb owner which may be beyond his ken for a while as an EV neophyte. I'm trying to help him out since he's making an effort to accommodate EVs, even if he's clearly new to EVs and their care and feeding right now.
He doesn't actually own an EV but he's considering one for the future. I recommended a Tesla, of course.
It's amazing how far I will go for someone to use my referral code. KIDDING!
