As the majority of 100% VG E-Liquids are thicker than traditional E-Liquids, we recommend only using a higher-wattage vape kit which utilises coils with large wicking holes. Wicking holes are the small inlets you can see from the outside of the coil, usually spaced around the circumference of the coil with an absorbent material peeking through.
If your coil has smaller wicking holes, you'll most likely experience dry hits or burning, as the coil won't be able to draw in the thicker E-Liquid quickly enough to saturate the wicking material. However, some 100% VG E-Liquids are thinner, and these will work better with vape kits and tanks with smaller wicking holes. Be sure to read the product description on the E-Liquid that you are buying to ensure that the kit you have is compatible.
