Most vapes are rechargeable, but not all of them. Some vape pens are designed to be bought, smoked, and discarded completely. There is no cleanup, no charging, and a reduced number of technical issues that you can run into with non-rechargeable e-cigs. Inside one of these entirely disposable pens are made out of the same parts of any vape: a battery, a coil, and a tank already filled with your vape juice. You can get models that have a single button you push to inhale, and others can be used just by inhaling, no button required.
