ENGLISH
Connecting/powering/charging electronic devices
Connect the cable (5) (circular plug to USB
socket) to the OUT connection of the USB-
WERK. Charging cables of all USB mobile
devices can then be connected to the USB
socket.
CAUTION: The USB connection to the de-
vices is neither splash nor rain water proof.
The USB-WERK emits up to 1 A current at a
voltage of 5 V.
Most USB devices feature an automa-
tic charging deactivation that prevents
overcharging. If such a deactivation is not
present and if the device shows the charge
status, the battery must be disconnected
from the USB-WERK immediately as soon as
it is fully charged. If such a deactivation is
not present and if the device does not show
the charge status, a warming battery is a
sign of the onset of overcharging.
CAUTION: If the cache battery was depleted and the USB-WERK not used for several
months afterwards, it is possible that at first no energy can be supplied. If during the
period of non use the USB cable remained connected to the USB-WERK, discharging can
occur more quickly. It takes several minutes of cycling for the cache battery to possess
sufficient energy once more. After that, normal operation commences.
This can be prevented by charging the cache battery prior to periods of non use. To do
so, it is sufficient to cycle for 10 minutes with the light switched off and no USB device
connected to the USB-WERK.

Integrated cache battery
The USB-WERK contains a cache battery
that keeps the energy supply constant
during slow cycling or stopping.
If the connected USB device requires more
energy than the dynamo is able to provide,
the integrated cache battery contributes the
energy difference. (When cycling slowly, the
cache battery discharges, whereas it char-
ges when cycling faster.) When the cache
battery is depleted, the energy supply of the
USB-WERK is interrupted so the battery can
recharge. As soon as a certain charge has
been reached, energy is once more provided
via the USB socket.
Tip:
Cycle for approx. 10 minutes at 15 km/h
with the light switched off and with no USB
device connected to ensure a basic charge of
the cache battery.
