EW-EC300 Charging Cable powers 12-speed Di2 systems with simple magnetic connection
What Our Gearhead® Experts Are Saying:
"I love how much simpler the EW-EC300 makes charging the new 12-speed Di2 setups. The magnetic derailleur port is super easy to use—no fumbling, and it snaps right into place. At 1.5 meters, the cable length is perfect for working on a bike on the stand. It also charges Shimano’s 12-speed power meter, which keeps things streamlined in the workshop. Reliable, straightforward, and way more convenient than the older chargers."
We turn to the Shimano EW-EC300 Charging Cable for fast, frustration-free power management on modern 12-speed Di2 systems. With a magnetic connector that attaches cleanly to the rear derailleur or compatible power meter ports, this cable makes topping off batteries intuitive whether we’re prepping for race day or maintaining a training bike. The USB-A plug adds easy compatibility with a wide range of chargers.
Built around Shimano’s latest Di2 architecture, the EW-EC300 supports the internal BT-DN300 seatpost battery while keeping our charging setup lightweight, compact, and dependable. It’s a simple yet essential tool that keeps electronic drivetrains running smoothly.
