Mini Shimano 12-Speed Di2 USB Charging Adapter — Works with Any USB-C

🔌 Slim Shimano 12-Speed Di2 USB Charging Adapter — Use Any USB-C Cable

Handy little lifesaver for Shimano 12-speed Di2 — compatible with Dura-Ace R9200 / R9270, Ultegra R8100 / R8170, 105 R7100 / R7170, GRX RX825, and power-meter cranksets R9200-P / R8100-P.

I’ve given a couple of samples to friends (I’m on Campagnolo myself) and they’ve all given it the thumbs-up — works exactly as it should.

Bring your own USB-C cable and charge anywhere — at home, travelling, or out on the bike.

Slip it in your pocket or bag — saves clutter and just works.

Perfect with a power bank when you or a mate need a quick top-up mid-ride.

Includes a handy lanyard — ideal to clip to your kit or bag so it doesn’t vanish when you need it.

No need for Shimano’s pricey OEM charger — this does the job perfectly with the USB-C leads you already own. Awesome bit of kit.

⚠️ Note

For Shimano 12-speed Di2 only.

Not compatible with 11-speed Di2 — those use a different connector and voltage via the older SM-BCR2 charger.
