Charging a USB device such as a smartphone or iPhone
You can charge a USB device, such as a smartphone or iPhone, by connecting it to the speaker via USB. Even if the
speaker is not connected to an AC outlet, its built-in battery can supply power to a USB device.
Note
While the speaker is supplying power to the other device, the auto power off (Auto Standby) function is turned off.
If the speaker is being powered by the built-in battery only, charging of the connected USB device will stop when the speaker
turns off.
When the CHARGE indicator and (power) indicator flash slowly, the built-in battery is running low and needs to be charged. In
this state, the speaker cannot supply power to other devices.
Music playback is not available with a USB cable.
