The Shimano EW-EC300 charging cable was specially designed for the Shimano Di2 12-speed road bike groups and is compatible with the components of the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 series.
The electronic Di2 system is charged from the rear derailleur, which has a corresponding connection. The charging cable can also be used to use compatible power meter cranks. It draws power from a USB-A connection.
