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; the energy is made useable to 
charge and/or power mobile devices.

• Voltage and current adjustable 
• Universal connections (e.g. USB) 
• Extensive accessories 
• Splash- and rainwater-proof

Universally usable 
With this dynamo-connected, universal powering device, voltage (up to 13.3 V) 
and current (up to 1.5 A) can be adjusted variably in small increments. It charges at velocities of approx. 8 km/h and faster. At only 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. 

Connection options of the E-WERK 
Universal connections for USB, Mini USB, Micro USB. 2 free cables for individual 
connections. With special plugs for SON and Shimano hub dynamos. 
Watertight cable screw joints.
