Auto-Draw Pod Kits: Specifically optimized for a perfect draw-activated experience. The pressure sensor and airflow are finely tuned to provide a smooth, consistent, and responsive draw that closely mimics the feel of a cigarette, which is critical for user satisfaction and nicotine delivery.

Rebuildable Dripping Atomizers (RDAs): Atomizers without a tank. Users manually drip e-liquid directly onto the exposed coil and wick. RDAs are renowned for providing the most intense and pure flavor possible, as the vapor travels the shortest distance. They are for advanced users who build their own coils.

Pod Housings: The plastic molds that form the outer shell of a pod. These are designed for precise fitment onto the battery device, featuring channels for airflow, magnets for secure connection, and a transparent window or material to view e-liquid levels. They are a key component in pod system manufacturing.

Durable Plastic Tanks: Utilize advanced polycarbonate or PEI plastic materials for the tank section instead of glass. These are virtually unbreakable from drops, making them ideal for clumsy users or active lifestyles. However, some plastics can be susceptible to cracking from certain "tank cracker" e-liquids (e.g., strong citrus, cinnamon).

Cereal Flavors: A popular sub-genre of dessert flavors that specifically mimic breakfast cereals, most famously "milky" cereals with fruit notes or cinnamon sugar cereals. The challenge is capturing the grain flavor and the sweet milk finish.
