I have a Rapoo H1030 wireless headset. I just got it and I guess I need to charge it first time. But I haven’t been able to charge it. The red light keeps blinking and I have kept it on the charger from some time now. I have no clue if I am charging it properly or not. I have connected both the USB and the charging cable and it has simply been blinking red since the beginning. What do I do? How do i charge the wireless headset?
