Power without mains - For all those that do not want to do without mobile phone, GPS, MP3 player or other electronic devices while cycling, Busch+ Müller has developed the bike-mobile E-WERK. Connected to a hub dynamo; Voltage and current can be adapted to charge and/or power mobile devices. Includes multiple adapter cables.
With this dynamo-connected, universal powering device can be adjusted variably in small increments. It charges at velocities of approx. 8 km/h and faster. At around 15 km/h it charges as quickly as standard mains connected chargers. It can be fed with up to 50 V DC, so that operation with an e-bike or car battery is possible as well.
