Hello gvoth.
Cup height is 3 3/8 " Diameter is 2 1/16" Cup depth is approx. 1 1/2". The connector says Minsoo-YC8-5P. AC adaptor is a SINGOF. O/P: DC 12v, 1A. I believe it is a 12 volt regulated. The feet are nothing more than foam rubber squash balls that friction fit into holes in the base. You just pull them out, or push them back into the holes. Also about the cup, the inside bottom is concave. Probably with the same curvature as the golf ball. Hope this is of some help to you. Cheers.
