I tried the e-werk, and I found it good for flat tours. As soon as yo go to California coast, Alps, Pyrineees etc the e-werk si not good enough. the FL is a notch over the e-werk. I canned the e-werk on this behalf. I found it unusable for the type of travels we are doing. Your question about the diagrams got answered already. I am charging battereis for my Garmin, my iphone and the camera batteries.
