The difference between prefilled pods and refillable pods

Prefilled pods and refillable pods are two different types of e-cigarettes, with different features and usage methods. Prefilled pods usually come with a single flavor and are usually pre-filled with e-liquid. They are usually disposable and cannot be refilled. Refillable pods can be refilled with e-liquid and used multiple times, and usually have a refillable battery. They are more popular in the market and can be used more flexibly.
