Busch & Müller USB-WERK
The USB-WERK can be connected to a dynamo hub providing 5 V at up to 1 A. An integrated small cache battery ensures that the power remains constant at slow speeds or short stops. That makes the USB-WERK an excellent solution to charge and power USB devices like mobile phones, GPS, MP3 players etc. Comes with a USB cable.
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.
The E-WERK can be connected to bicycle frames of different diameters, in any suitable position using rubber bands or cable straps. The E-WERK is splash and rainwater proof.
