SPACE CLUB Disposable vaping device or e-cigarette is a device that comes ready to vape, and you can dispose the gadget once it runs out of charge or e-liquid. Most e-cigarettes need to be re-filled, either by a re-filling the e-liquid in the tank or by replacing the pod. A disposable, anyway, is different. Disposable are designed to be used and throw away once the liquid has run dry.
