If you are just starting out with vaping, we don't recommend choosing a mechanical mod as your first device as these devices do not have the inbuilt safety features of our standard vaping kits and require some additional knowledge of handling and monitoring lithium based batteries.
A mechanical mod is a very basic personal vaporiser device. It is a tube that holds a replaceable rechargeable battery and on the tube is a button that when engaged completes a circuit that delivers unregulated current to the atomizer. A mechanical mod contains zero or little wiring or soldering, nor any electronics.
A major reason some vapers choose a mechanical mod aside from aesthetics is their durability. In a typical personal vaporizer, the device is heavily dependent on electronics and if any component fails, repair is usually not possible for the average user. Some electronic personal vaporizers are also basically a disposable device in that once battery end-of-life has been reached, the battery cannot be replaced.
Some choose mechanical mods for the ability to run low resistance atomizers that cannot be run on other forms of vaping equipment; however, this is riskier than using standard resistance equipment, so requires special care.
