Mech vs unregulated CONFUSE...
There is absolutely a limit to the current you can run in a mech. This is determined by the continuous discharge rating (CDR) of the cell, and if the mech in question is serial or parallel if it uses more than one battery.
Knowing battery safety is especially important using a mech because there are no safeguards other than your willingness to learn and follow safety measures. If you have an atomizer short or a resistance that is too low most regulated mods won't allow firing. A mech with a shorted atty can cause the battery to vent.
The same limits (set by the physical technologies we use) apply to regulated mods, though a great majority of them can determine its
batteries aren't up to CDR spec by their voltage sag, it isn't a sure bet for your personal safety.
People chose mechs over regulated devices as there is essentially nothing that can fail, they are often more rugged and compact than regulated devices. Most people that run mechs also rebuild their own atomizers, so we can get the vape we want pretty easily. A lot of mech heads got into mechs when they were really the only option for a larger, higher capacity device vs the cigalikes and egos. A lot of people seemed to have gotten into them with anxiety over a possible vapocalypse.
I have both, but the form factor of a single cell tube mech is hard to ignore. I usually have a prax1s or stingray in my pocket, takes up less space than a pack of smokes did.
