QuestionMy light does not charge correctly anymore, I need waggle the cord to make the indication light turn red
AnswerIndication light turns red: light is in charge.
Indication light turns green: light is either fully charged, or battery is not taking charge any more.
The correct voltage output of the charger is 4.5-4.7 volt.
It sounds like the charging port is not blocked, you can use cleaning alcohol to clean the inside, make sure it is dry when you need to plug in. If it still will not work, you can send it in for repair, the repair is free, turn around time is typically 2 weeks. Or you can buy a switch unit (which has a new switch and new charging port)
