The charging efficiency can be different compared to the charging from the usual mains power supply. Depending on the type of the connected USB device and the frequency of use, the charging current may not be sufficient to charge the battery of the con- nected device. Some connected audio sources may not be recog- nised and cannot be charged. A USB device can be connected directly to the USB port or via a connection cable. We recommend using connection cables from the ŠKODA Original Accessories range. USB extension cables or reducers may affect the playback function of the connected device.
