Vape pens are essentially small vaporizers in the shape of a small pen or e-cigarette. They are usually very discreet, easy to use, and way cheaper than robust portable and desktop vaporizers. Vape pens almost always use conductive heating (as opposed to the preferred convection heating method). Therefore, it is essential to understand how to operate them to make sure your product does not get overheated or even burnt. Nowadays, the market is flooded by a wide range of vape pens.
