Why does my B1 have no power?
For starters, try pressing the Bluetooth LED on the front of the B1 to confirm it's not on. If the device that was paired with the B1 last is out of range or has been turned off, the light on the front of the B1 will turn off and remain off until the LED button is pressed.
From there, to assure it's not simply an issue with one of the accessories, swap out the USB cable and the USB AC adapter to see if that fixes things. If you have a micro USB cable laying around from an older cell phone model, you would be fine using that. And most current cell phone USB power adapters would work just fine with the B1.
If you have no success with either of the above, try plugging the B1 into a different power outlet to see how the unit reacts. If there is still no indication of the unit powering on, please contact our Support Team for further assistance.
