Innokin - Cartomizer for AIO
Filling Cartomizer Remove the plastic cap on the top of the cartomizer; use a paperclip, or something small enough to fill into the small hole, and pull it out. If you can see the material around the centre hole of the cartomizer, you can pour E Liquid into the unit.
Hold the cartomizer at a 30 degree angle and start dripping in the E Liquid. The idea is to pour into the side avoiding the middle hole.
