I noticed that all the chargers are Electrify America. Good choice as in my opinion they are the most reliable. Be sure to get the Electrify America app. It will save you money and is more reliable than using a credit card. PhilBo used abetterrouteplanner. I prefer plugshare as it is much easier to use. One more thing to consider is---what is the plan if one of the chargers does not work? Are there more L3 chargers nearby? The map would tell you.
