Regarding “opportunity charging” on 120v. It is generally a hassle. What is you kWh cost?
You’re Southern California, so let’s assume high. $0.30kWh. That’s just under $0.50 per hour of being plugged in. It just isn’t worth the hassle when your at a restaurant, etc. also, IMHO, it’s pretty questionable plugging into a random outlet. Is that simply theft?
Regarding work charging. Sure, that will keep growing. But they also expect it won’t be free forever.
Anyway, when I first got my car, I was plugging my into every public free charging station I would find. When I figured I was saving ~$20 month I quit. Wasn’t worth the hassle.
I believe all these tools should be in the tool belt. But most folks will simply rely on home and work charging. And may select between the two based on cost.
Finally, if you dint drive much, a 120v outlet might meet your needs.
You might also find that you can convert an existing plug in your garage to 240v 20a. Do you have a dedicated water softener outlet or a dedicated fridge outlet (or any single plug in a single circuit in your garage).
Oh yea, a Wall Charger looks cool. But really not necessary for most people. But they are fantastic for sharing power between multiple cars. And at a good price point based on functionality.
