I just got a passthrough from liquid nic stix. it was the cheap one they sell. when I plugged it into my computer I pushed the button and the led lit up fine. however when i put on the atomizer and put some liquid on it and pushed the button again the led kept blinking. when i unscrewed the atomizer and tried the battery again the led lit up fine. It's a 306 atomizer. anyone know why this is happening?
