Cleaning

Keeping the G Pen Battery clean helps the overall performance and longevity of the product. 

Remove any unwanted concentrate residue from the power button and connection point with a G Tip or Q-Tip soaked in rubbing alcohol. Keeping these areas clean will ensure that the connections remain established and the battery functions at a high level. 


If you have any further questions, our customer service hours are 9:30 to 18:00 CET.
