Vaping has become a good way to start your self from avoiding those toxic cigarettes that you've been living just to take out stress. Did you know that smoking really kills? Yes, it does not really kill you right after you smoke one but what it does is lessens your life years from 80-70 years to 60-50 years. With the new technologies that were developed and helped people to stop smoking such as nicotine patches, vaping wins ahead since it doesn't contain any toxic chemicals, not like cigarettes. Years and years people from the media are trying to sabotage the vaping industry such as water lungs wherein water lungs are really induced by an allergic reaction from specks of dust. The only problem with vaping is the user's less knowledge of vaping such as ohm's law, battery protection, and series to parallel types of vapes. Before then vaping started off as Vape pen, that has built-in batteries wherein a lot looked like a regular cigarette where the end lights up when inhaled on the other end, then came in the mechanical mods this is where beginners had lots of problem due to less knowledge of ohm's law and connection of battery such as series and parallel, good thing the variable mods came in where it has these chipsets that regulates the voltage and amperes produced by the battery and those variable mods also show the value of resistance that the coil placed. A regular vape contains Atomizer - this is where the coil and cotton is placed, Mod - this is where the Atomizer sits with the 510 connection, 510 also means the type of thread which is M7x0.5 and also the battery. The difference of variable mod from mechanical mods is that variable mods has a chipset and can do temperature control so that your cotton never burns out and also protect your battery while mechanical mod only produces the voltage left on the battery.
