I noticed that they delisted the 100w. The 120W is only about $26 more. I didn't take any photos of the connector. The main cable has a connector on both ends as well as batter clips wired to a connector and cig plug wired to a connector.
I bought some additional connectors so I could make an extension cord as well as a hard wire to my FWC batteries. Just finished the install today and it works great. I also put a 10 A fuse in line to prevent any problems to my electrical system. One note for anyone who buys these, check the terminal block on the controller. On mine one of the panel wires was pulled out. When I went to insert and tighten, all of the screws were loose. I did notify them of this so maybe they took it off the site to inspect the remaining ones.
