Cinq Plug5 Pure USB Dynamo Charger

Cinq Plug5 Pure USB dynamo charger, made in Germany. It replaces the headset top cap and expander, and delivers a steady 5 V through a USB-C port on top of the steerer. No add-on box and no visible cable.

The electronics detect when the lights are switched on and switch modes accordingly, negotiate the charging current with the connected device and get the most out of the hub. A rotating cap keeps the port dry when not in use.

With up to 700 mA, it continuously powers a GPS, a bike computer or a tracker, or tops up a phone. For more demanding devices, Cinq offers the Smart Power Pack II buffer battery.
