B + M K-Werk Powerbank with USB Dynamo Connection

The K-Werk from Busch+Müller is not only a flexible energy storage system for travelling, but can also be charged via the dynamo while cycling to provide you with self-sufficient power supply. Powerbanks have become helpful companions as mobile power supplies when more storage is needed for mobile phones and the like while on the move.

As a further development of Busch+Müller's USB-Werk as a charge controller and as an alternative to the LUMOTEC LUXOS headlamp, the charged battery of the long-lasting K-Werk supplies constant energy to power smartphones, sat navs or action cam batteries, for example. Even without cycling! Simply strap it to the bike frame as a compact power station. The power supply from the bicycle dynamo to the mobile battery is extremely simple via the plug-in connection cable.

With the powerful K-Werk powerbank, you are completely independent of the power grid. Ideal for charging devices via USB when travelling on short and long tours, without recharging via the socket, which is of course also possible as an alternative.
