Bike Radar say “If you’re running, or thinking of running, a dynamo hub then this little gadget will be of interest to you. You plug it into your dynamo (or any other source, such as a light battery for example) to give it power, and then you use the small selector dials to choose what voltage and current you want it to give out (2.8-13.3 volts, and 0.1-1.5 amps). You then attach the item you want to power using the enclosed leads and voilà, you have a very handy device for supplying power to almost anything, from almost anything. We have charged mobile phones, GPS units, pocket PCs, MP3 players and even the batteries for main lighting systems using the E-Werk. A few devices might well see the connection as a data connection – although nothing we tested did this – but it performed faultlessly throughout testing. This is an outstanding little product that has more uses than you can shake a stick at.” 4 1/2 stars.

Please note : The Ewerk (even with Cache Battery) does not support Apple I devices with Software freeze 4.3.3 older versions are fine.

WARNING: It is the responsibility of the user to select the correct power output for the device being used in conjunction with the E-Werk. Neither Busch & Muller or Strada will be liable for any damage caused to other equipment connected to the E-Werk.
