This video explains how to charge the battery of the ONYX STUDIO 6 wireless bluetooth speaker. This process works in a similar way for the older models of this speaker, like the ONYX STUDIO 5 or ONYX STUDIO 4.
When the LED just under neath the power button starts to blink in red, then it is time for the speaker to be recharged. Connect the barrel connector of the charger with the charging port on the back of the speaker. The port is hidden behind the waterproof latch.
While the battery is being charged, the LED in the front of the speaker will be constantly red. A full charge takes up to 5 hours.
The the LED turns off, the charging process is completed and the charger can be removed.
BTW, it is possible to use this speaker during the charging process!
