CLOSED POD SYSTEM
Closed Pod systems have sealed pods that are pre-filled, however open Pod systems have refillable pods.
The closed pod system was the first type of pod device to take over the market. It consists of a battery and a pod cartridge that already contains juice. Typically, the manufacturer of a closed pod system will offer a selection of flavours. All that you have to do is snap the pre-filled pod cartridge into the battery and vape away.
These devices are especially popular with vapers who don’t want to put a lot of effort into enjoying their vaping experience.
