A:AnswerThe charger light flashes green when still charging (while device is in the charger). The charger light on front of charger will turn to SOLID GREEN (no flashing) when fully charged. It took 2.5 hours for mine to fully charge the first time.
There are also flashing green or amber or red lights on the back of the necklace device and those lights should not be confused with the light on the front of the charger unit, as the light mean different things on charger versus lights on the necklace device.
