The Plug II is the advancement of the first frame integrated power supply, for charging or supplying USB-devices via dynamo hub. One of these evolutions is the extended functionality of the TopCap, which allows charging the iPhone® without using a special cable. Also the Plug II can be directly connected to an E-Bike battery. The revised design with the full integration of the entire electronics into the TopCap offers a clean bike design, easy retrofit as well as a very good theft protection while providing more power. The Plug II converts power from an existing dynamo hub into USB standard.
