USB Port Charging

To charge the radio, insert the supplied USB
cable to the power source.
The charging indicator will stay red. After
fully charged, the red light will turn off.
It takes 4 hours for the internal 1100mAh
Li-ion battery to be fully charged.
When completely charged, the battery will
deliver 9 hours of radio play(depending on the
volume) or 8 hours of Bluetooth speaker time.

Product Features

This product uses 1100mAh, rechargeable,
built-in polymer lithium battery. It has passed
the safety test and certification, and the
capacity is larger than most of the same size of
the Bluetooth speaker, so there is a longer
working time.
This product uses a high-end professional
radio chip, using a special antenna and
matching circuit, coupled with other
professional-grade circuits, making its
receiving sensitivity better than other
performance.
