@SylverReZ 'member old mech mod and ohm meter coil building days? cuz I 'member my boy showing me a setup a shop built em and after 5s of a hit the battery button would get VERY hot.....told em to change that fucken coil ASAP
I think most of today's e-cigs are undervolted and have safeties built in, back when they were first starting it was Wild West out there, just a bunch of crap imported in bulk from China that tended to explode at the drop of a hat.
