Here's my experience with various charging networks:

- EVGO is excellent. They have L3 (chademo/sae) chargers in lots of locations, and they work. I believe they own the chargers. The chargers seem to be 400v/100a = 40kw.

- Chargepoint is very good. They have reliable chargers, just not many L3 chargers. Most of their chargers are L2 (~6kw). I don't think they own chargers, or they own only some of them. But they are reliable and/or have good service.

- Blink has always disappointed me - L3 is unreliable and always broken. Some L2 chargers work.
