If you have a compact, non-rechargeable device precharged and prefilled with e-liquid, you call it a disposable vape. Most disposable vapes can't be recharged or refilled, and you don't have to buy and replace coils, which is how they vary from rechargeable mods. The disposable model is thrown away when there is no more e-liquid.
Using a disposable vape is a simple and economical way to start vaping. It is a good option for individuals who want their vaping experience to include the least effort possible because all you have to do is inhale and move on. A disposable vape is excellent for individuals who like to vape "n' go" rather than fiddle with different settings and modes.
