How do you know if a ooze pen is charging?
Authentic Ooze Smart USB Chargers should light up red when your vape battery is charging, and the battery light should light up green. When your pen battery is fully charged, the charger light should turn green and your battery light should be off.
Why is my ooze pen not lighting up when charging?
First, make sure that the pen is turned on by pressing the button on the side. If the light doesn't come on, the pen may be out of battery and will need to be charged. Once the pen is turned on, lightly press the tip of the pen against a piece of paper to see if any ink comes out.
