I bought the plug-in version of the Charge Point level II charger from Amazon in 2015. Didn't like the idea of having a charger hard wired. When it arrived, I found the stud to mount it above my 240 V plug, drilled the holes, put in the screws, and had the charger installed and working in less than half an hour.
This charger that I got new last year has WiFi and based on my location, knows the utility rates, etc. I can look at the trends and see that I generally use about $27 of electricity per month. On my phone I can see every time I charge, how long, and how much it cost to charge as well as the monthly trends. I spent extra $ to get this WiFi capability with the level II charger and think over the long run, it is worth the extra $.
