There are many free stations here in Los Angeles. I would say the majority of them are Clipper Creek units. They seem to be built very well and withstand any weather.
As much as I'm a Tesla fan, I really don't believe in building public charging stations that can only be used by Tesla. No matter where, I would always install a normal EV plug (J1772) that everyone can use.
In this case, OP wants to make charging available to everyone so this is a win-win.
But I'm sometimes torn. If I visit a hotel, I'll often suggest they install a HPWC.
The pitch is easy: No risk.
Tesla provides the HPWC. Facilities management (usually) can run power at low cost.
If nobody stops to charge: no cost to hotel.
If lots of people stop to charge: more guests and services (rooms, meals, recreation) sold.
Marketing: Inside the car and on Tesla's website.
The alternative is a Clipper Creek.
They have to spend between $500 and $2500.
If guests don't come, then they are out the sunk cost. And the warranty runs out. And it needs to be maintained.
If guests come and charge, great, but how do people find out. Do they need to market? Which cars can charge? How far can they go?
