E-liquid vaporizers simulate the feeling of smoking, but without tobacco or any of the harmful additives that are used in the manufacturing of cigarettes. Their use is commonly called "vaping." Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor, typically released by a heating element that atomizes a liquid solution known as e-liquid. Simply fill the tank of your vape pen with e-liquid and reattach the mouthpiece. You're now ready to enjoy your vaporizer pen. E-liquids come in many different flavors. Most vaporizer pens are easily rechargeable by a USB port, like the Aspire E-Liquid Premium Vaporizer Kit. Some vapes even use bluetooth technology for peak performance, like the Vaporite Amber Mini Protank.
