Thank you everyone for your entries so far. I ranked them this morning and wanted to add a few more comments. We like the green and black color combination the best so far in #12. Both the idea of the lightening bolt and the outlet work well and the logo concept with our name is starting to come together. There is a new standard outlet that will accompany these vehicles and a handled cord that I think could make sense with our logo. I am not sure if I can upload pictures here as an example, but I have included 2 links below that have a picture of the charging plug end. If you click on the picture of the charging station that says "ChargePoint" it will take you to a photo gallery with some better pictures of the connector.
