The Shimano Di2 Internal Battery Charger makes charging your Di2 electronic shifting system a snap. With its indicator lights that tell you when it's charging and when it's fully charged, you don't have to guess. Plus, a full charge takes just 90 minutes. But don't worry too much about missing a charge--your system will only need to be charged every couple months.
