There are a number of different types of vape kits available, including starter kits, pod systems, sub-ohm devices, and disposables.
Starter kits, as the name suggests, are devices that are designed specifically for new vapers. The airflow and power output of the devices is designed to replicate the feel of a cigarette, to make the transition from smoking to vaping as easy as possible.
Pod systems are also often designed for new users and tend to be small and compact in size. There are two different types of pod systems available, prefilled, and refillable. Prefilled pod systems require pods which are purchased prefilled with e-liquid and cannot be refilled. Once the pod is empty it can be disposed of and replaced with a new one. Whereas refillable pod kits come with pods that can be refilled with your choice of e-liquid multiple times before either the coil, or entire pod will need to be replaced.
Sub-ohm devices are recommended for advanced vapers as they are not usually designed to replicate the feel of smoking a cigarette. These devices have a coil resistance lower than 1 ohm and are usually high powered and used for direct-to-lung vaping.
Finally, disposable devices are designed for short-term use, ideal as a back-up device or taking on short trips and nights out. They are compact and completed closed systems, which come prefilled and pre-charged, and are designed to be disposed of once the device is empty.
