CHARGING A MOBILE DEVICE

The USB socket on the left side can provide DC power of 5V/1A for charging a mobile device. Connect the mobile device to the USB
socket with an appropriate cable of the mobile device (not included with the Bluetube speaker). The USB power is available in all
modes, including standby mode. Refer to the user manual or the manufacturer of the mobile device to verify if it supports charging
from an USB power. The USB socket is suitable for DC power-out only and cannot be used for e.g. playback of music from a USB
stick.
Warning: Never use the USB socket in rainy or moist conditions to prevent moist from entering the Bluetube speaker and
so to prevent potential short circuit. Always keep the rubber cover well closed under these conditions.
NOTE: It is recommended to use AC mains power while charging a mobile device via the USB socket. On battery power it is also
possible to charge a mobile device from the USB socket, however using battery power to charge a mobile device will consume much
energy from the battery and so drain the battery fast.
