Some sensitive mobile electronic devices react to voltage fluctuations by interrupting the charging process. Since the E-WERK is connected to a hub dynamo, it cannot supply power free of those kinds of fluctuations. The cache battery stores excess power from the ride and compensates in low speed / short stop phases thus preventing charging interruptions.
