Di2 Charger
Shimano Di2 EW-EC300 Charging Cable
The USB charging cable for 12-speed Di2, clipping straight into the rear derailleur so the internal battery never has to come out. It also charges Shimano's 12-speed power meter cranks.
Highlights
Why we rate it
Charge through the derailleur
Plugs into the charging port on the 12-speed Di2 rear derailleur, topping up the BT-DN300 without removing the seatpost.
Quick top-ups
A flat battery is back to full in around an hour and a half from any standard USB power source.
Doubles for power meters
The same cable charges Shimano 12-speed FC-R9200-P and FC-R8100-P power meter cranksets.
Generous length
At 1.7m it reaches from a turbo-trainer bike or workstand to a wall socket or laptop without fuss.
Handy spare
Worth keeping one at home and one in the travel bag or race kit.
