How do I clean my SERIES-B DNA 75w?

From time to time, the 510 connector on the SERIES-B DNA 75W may need to be cleaned. A build-up of e-liquid residue may develop through general use, which can inhibit power delivery, or prevent the device from getting a clear resistance reading from the attached tank.


To clean, simply:

  • Remove the attached tank from the device.
  • Use a pin/needle to clear the connector and battery threads. Doing this will clear away any dirt or debris that may be preventing a good connection.
  • Use some paper towel or cotton wool to wipe away any leftover residue that may be left on the connector and battery threads.
