The Tesla charging stations are very competitively priced and known to be reliable.
The Tesla "mobile connector" that Fenderfour mentioned is an exceptional value: like ~$230 or something, and it can do 120V and 240V (at 32A, which is a mid-range rate for 240V). That will get you ~13 miles to ~26 miles of range per hour of charging depending on how efficient the EV is. If you have a non-Tesla EV (unless it's switched to the Tesla port as many are over the next few years), you'll also need a ~$150 adapter to use with this. This is what I did when I bought my current non-Tesla EV.
There's also the Tesla "universal wall connector" that is a hard-wired option that has a built-in charging adapter, letting one easily charge vehicles with the Tesla port and the J1772 port that most non-Teslas have, currently. It's ~$550. It can also charge up to 48A, which maxes out most EVs as far as AC charge rate. That will get you ~20 miles to ~40 miles of range per hour of charging depending on how efficient the EV is. (Less, if it's interstate driving in 0*F weather, but these are ballparks)
There are other brands generally considered reliable, like Grizzl-e, etc., but the value and time-proven reliability of the Tesla charging stations are hard to beat.
