Hi folks,I purchased this device today directly from SEG Electronics Market, Shenzhen. When I put this device for first charging the red charging light started glowing. It has not turned off despite 5 hours of charging. Does the first charging take that long? The battery was 40% charged when I got it. I have begun to think that the device is not charging properly and hence the red charging light is on. Should it turn off if the battery is completely charged?Appreciate your help on this.Regards,KS
