Product Description

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. If the compact device is connected to the hub dynamo, the electricity generated by the cyclist's muscle power does not have to be used by only the lighting fixtures but can alternatively be processed by E-WERK. The energy is given off via two included connection cables that tinkerers can equip with plugs suited to their individual applications. Alternatively, the user employs an also included USB cable - the standard connection par excellence that offers compatibility with a wide range of devices - making sure that his electronic equipment does not run out of power while he is on the way. A small stylus that is housed at the bottom of E-WERK is used for adjusting two turning knobs controlling voltage (2.8 to 13.3 V) and current (0.1 to 1,5 A) quickly and variably for all the usual applications. E-WERK provides power of up to 16 W, and all that with idle losses of only 0.03 W at 30 km/h! At a speed of 15 km/h, E-WERK already charges as fast as a standard mains connected charger. An extension cable offers the possibility to tap into E-WERK's energy supply at virtually every spot on the bike. Cable screw connections keep the all links securely water tight. In order to mount the "miniature powerhouse" on the bicycle frame, three differently sized o-rings and cable straps are included. Some devices, such as the 3GS iPhone, require a constant voltage from the charger. For devices like this, an intermediary or buffer cache battery must be used. The E-WERK will charge the battery, which then charges the device. The Busch & Müller cache battery can be charged by the E-WERK while simultaneously charging the device. THIS UNIT COMES COMPLETE WITH THE CACHE BATTERY AND ALL OF THE ASSOCIATED CONNECTORS. THE BATTER IS NORMALLY AN EXTRA £40!

If you're looking to use your hub dynamo to power devices on your bike this is a must-buy. Small, lightweight, and it came with every cable, adapter, extension and mounting mechanism imaginable.

However note that at present time this item is being sold for £130 by this seller - it's available for half that price elsewhere, I have no idea why it's so expensive here.

Excellent well built device that delivers exactly as promised. No issues at all . Ideal for those seeking to charge devices on the move. Suggest using the additional battery to ensure maximum benefit.

Cache battery is NOT included in the sale with this item. It is an expensive option just for the unit alone.
