What is E-Liquid ?
E-Liquid is the fluid that is vaporized in an electronic cigarette. E-Liquid varies in strength from 0 nicotine content to 36mg nicotine content. Most E-liquid bottles come in 10ml, 15ml, 20ml, 30ml, and 50ml sizes.
Please not that 30ml equals about 600 drops and the average amount of drops to refill an empty cartridge is 5-10 drops depending on the unit being used. The Joye 510 requires about 5 drops of E-Liquid to fill the cartridge.
