OK, so I have only used the equipment that came with the car. No problem and pretty easy to use. However, in searching for other ways to "fillup" so to speak, I came across a Charge Point site quite close to my home and surprise, surprise, it's free to anyone. So, do I just pull up, hook up and charge, or do I have to be signed on to Charge Point to use it even if it's free? It is not a DC type system but it is a level 2 charger and on the system signage it states 8.8kw I believe. The only restriction I saw was a request to limit your charge to 4 hours. Help!
