Home charging units

Check with your electric company as they may have rebates and incentives -- but only for specific chargers. I used one at my old vacation house and said rebate basically covered the cost of the charger and install.

Also, when thinking about Level 2 charging, I recommend using kWh per hour of charge over miles per hour of charge because each vehicle is different. Someone above said their Tesla charged at 32amps and 26 miles of charge per hour whereas that same 32 amp connection would would only get you 12-15 miles in a Rivian (about 6.6 kWh/hour @ 2miles/kWh). The general math I use for mt truck which has averaged 2 miles/kWh is:
60 amp circuit charging at 50 amps = 11 kWh/hour ~ 22 miles of range
50 amp circuit charging at 40 amps = 9+ kWh/hour ~ 18 miles of range
40 amp circuit charging at 32 amps = 7ish kWh/hour ~ 14 miles of range
30 amp circuit charging at 24 amps -= 5.5 kWh/hour ~ 11 miles of range

I have an extension cord set up that I've used at Air B&Bs to charge. At one stay, we coordinated two Tesla's and the Rivian over the course of the weekend at 24 amps of charging and everyone was able to charge. In that case we were limited to 24 amps of charging as the extension cable is only rated at 30 amps.

On my home charger that charges at 40 amps, it typically takes 6-8 hours to go from a 25ish to 80% charge.

I love the clear table.

Right now, I have L1 charging on 120v 15A (really 12A), and that nets 1.4kWh/hr and 2 miles of range.

So even the most modest upgrade to L2, if you're on a 20A or 30A circuit, will be a tremendous improvement. There's no need to go whole hog on 48A for most folks.
