I am on Energizers website attempting to provide the details about the Surface Pros connector so that they might get us one for the portable power units they sell. Does anyone have exact tip specs? Inside Diameter, Outside Diameter, Length, Width Depth? I cant find anything in my house at 5am that has mm designations and the Iphone apps are laughable. EDIT: Found a ruler and it appears the connector is 20mm long, 4 mm wide and 2 mm deep. Anyway I did the best I could on the website.
