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.

Sachet Instructions
1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.
2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
7. Go clean that filthy bike!
