POD Vaping is similar to a standard electronic cigarette. There is a battery and a cartridge filled with vaping liquid. A POD generally contains more liquid and sometimes a larger atomizer, producing more vapor and stronger flavor. Also, the battery is normally larger which can give you more vaping time between charging.
Although it is still smaller than a refillable vaporizer, SmokePod is larger than an ecig so keep this in mind when deciding. Many consumers will have one of each to use in different situations.
POD kits normally come with a battery, 1-3 cartridges and a charger. Some offer a choice of flavor and nicotine strength when you order. Easy to carry and great vapor - worth a try!
