Why doesn't my boomphones pocket speaker charge up

When I plug it in to charge the green indicator light turns on and stays solid,then about 3 minutes in the blue Bluetooth light comes on as if the power was turned on and then I pushed the power button again and the blue light went off as if I turned the power off and it will keep doing that so I just left for a few hours with both the green and blue lights on solid and when I disconnect the charging cable it goes dead and doesn't turn on like it didn't charge at all. Is there a way to fix this?
