ATWEINA USB-C Charging Adapter for Shimano 12-Speed Di2
The ATWEINA AT-0024 is a compact USB-C charging adapter for the compatible Shimano 12-speed Di2 systems and power-meter cranksets listed below. Its USB-C socket accepts a separate USB-C cable, while the four-contact end connects to the compatible bicycle component's charging port.
Use it to charge the Di2 system through the compatible rear derailleur, or a listed power-meter crankset through its charging connection. Supplied with the pictured lanyard. This is an ATWEINA aftermarket accessory, not a Shimano-branded original part.
Check the charging port and model before ordering. For the listed 12-speed road/GRX systems and power meters only. It does not recharge wireless shift-lever coin-cell batteries and is not the older 11-speed Di2 SM-BCR2 charger. USB-C cable and USB power supply are not included.
Key Features
- USB-C connection: Connects a separate USB-C lead to the compatible charging port.
- Four-contact adapter: Matches the connector arrangement shown in the product photographs.
- Compact size: Approximately 23 × 21 × 15 mm.
- Lightweight: Manufacturer-labelled net weight of approximately 4 g.
- Lanyard included: Handy for keeping the small adapter with your cycling kit.
