Some sensitive mobile electronic devices react to voltage fluctuations by interrupting the charging process. The E-WERK is connected to a hub dynamo which can at slow speeds supply fluctuating power. The solution is to use the Cache battery which constantly supplies 5V which is the standard voltage required for charging via a USB connection. The cache battery effectively harmonises the voltage supplied and prevents charging interruptions.  It stores excess power from the ride and compensates in low speed/short stop phases thus preventing charging interruptions. The E-WERK will charge the Cache battery at approximate speeds from 15km/h and faster to a capacity of 80% after about eight hours. The LED indicator glows to show that the battery pack is charging. The battery comes in a nylon bag that can be fixed on to bicycle frames of all diameters using an adhesive cloth tape.
