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. 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. By the way: Also available at Busch & Mueller is the Universal Cockpit Adapter, the ideal accessory for E-WERK, because this adapter makes it possible to keep all connected devices safely on the handlebar directly in the cyclist's field of vision.

Indispensable accessory for touring cyclists

Poster le 2011-11-19 par  Leeds. UK

Now that mobile phones are very expensive I don't want to leave mine unattended at camp site wash rooms while the battery is charging. The e-work has proved to be an excellent charging unit and worth every penny/centime/cent of its purchase price. The only caveat is that iPhone users will need to buy the auxilliary battery unit to be able to charge their phones.



Great Power Accessory

Poster le 2012-01-24 par  Kentucky. USA

Purchased the E-Werk so that I can keep my cell phone. MP3 player. netbook. and other electronics charged while touring. Have it attached to a SonDelux hub. I'm very happy with the E-Werk. it works as advertised. I recommend it to anyone wanting to use electronics will riding.



Absolutely Great For Touring

Poster le 2012-08-22 par  Chicago

This charger is great! I have used this pretty extensively for several months now. It has been extremely dependable and easy to use. The charger is a great thing to have along while touring and works as promised. It keeps up with my Garmin E-Trex 30 all day long at full brightness. I use a Duracell recharble USB battery to act as a buffer. The bracket is a nice feature. I will be buying a couple more of these for sure. Nice job Busch & Muller.
