8. Charging the Integrated Rechargeable Battery

The USB connection on which the device is charged must have a resilience

of at least 500 mA. This is usually ensured at every USC connection of com-

puters. However, the device may also be charged with mains units offering a

higher resilience. In this case, the service life reduces accordingly.
