Shimano Di2 EW-EC300 Charging Cable

The Shimano Di2 EW-EC300 Charging Cable is the dedicated charging solution for Shimano Di2 12-speed electronic groupsets — the cable that keeps your system running so you can keep riding. At 1700mm in length, it gives you enough reach to connect your internal battery without awkward positioning or hunting for an adapter. It also handles charging duties for Dura-Ace and Ultegra power meter crank arms, consolidating what you need to keep your drivetrain and data fully operational.

There is no substitute for the correct charging cable when your Di2 system uses a proprietary connector. The EW-EC300 is the straightforward answer — purpose-built hardware that removes any guesswork from the charging process.
