The E-WERK makes hub dynamo energy universally useable and supplies mobile devices with power in variable voltage and current. With the cache battery 461A, the bike-mobile power supply unit is even more universal and an even smoother operation is made possible. For some few devices cannot be powered or charged when the voltage they are fed with fluctuates or is interrupted. When one cycles slowly, the energy created by the hub dynamo and transformed by the E-WERK first drops and reaches zero when the bike stands still. Some devices react a bit touchily to these fluctuations and switch off. Other devices have to be manually switched back to powering by the E-WERK after stops.
The high output, hub dynamo powered universal power supply and charging unit For all those who do not want to go cycling without their mobile phones, GPS, MP3 players and other electronic devices and do not have access to a stationary charging station comes the "bike mobile" E-WERK.
The double IION - the latest development in SIGMA rechargeable batteries is called the IION XL. It is, as its name suggests, the larger version of IION. Its 4 Li-Ion cells provide optimum energy for the POWERLED EVO and almost double the burn time of the KARMA EVO.
Small, light with plenty of Li-Ion power. It benefits in particular from its low weight (140 g), its high energy ratio and its resistance to extreme temperatures. Its low self-discharge makes the IION much more efficient than NiMH or lead rechargeable batteries.
