Many vapers prefer pod systems, also called vape pens. These are so popular because of their simplicity compared to box mods. Pod systems are smaller, more discreet, and resemble the shape of a cigarette more so than a box mod. Those making the switch from traditional cigarettes to vapes will probably be more comfortable using pod systems, at least at first. There are also much fewer pieces to worry about cleaning and maintaining with pod systems. There is a body, which contains the rechargeable battery and the coils. Disposable cartridges, or pods, are attached to the body, and the vape is ready to use. When the pod is empty, it can be replaced. You don’t need to worry about cleaning or refilling any tanks.
