The Shimano EW-EC300 Charging Cable is specially designed for Shimano Di2 12-speed road bike groupsets and is compatible with components from the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 series.
The charging process for the Di2 electronic system is done from the rear derailleur that has a corresponding connection. However, the charging cable can also be used for compatible Powermeter cranks.
