An e-cigarette is a vaping device designed to look and feel like a traditional cigarette. It consists of a battery, a heating element, and an e-liquid tank.

A pod system is a type of vaping device that uses replaceable pods or cartridges to hold e-liquid. It's typically smaller and more portable than other types of devices.

A box mod is a type of vaping device that is typically larger and more powerful than other types of devices. It usually has a box-shaped design and allows for more customization options.

An atomizer is part of a vaping device that heats up the e-liquid and produces vapour. A tank is part of the device that holds the e-liquid and delivers it to the atomizer.

Coils are the heating elements in a vaping device that vaporize the e-liquid. They work by heating up when the battery is activated, which heats up the e-liquid.

Vaping devices can use a variety of batteries, including built-in rechargeable batteries and replaceable batteries such as 18650s and 21700s.

E-liquids come in flavours and nicotine strengths. Ingredients typically include propyleneglycol, vegetable glycerin, flavourings, and nicotine. Some e-liquids may also contain other additives such as sweeteners or cooling agents.
