Not to be rude but i dun believe you
vape 500w. 100 watts is hellish hot, 120w whoa am not wanna do that again, 150w I am never ever doing that ever again..
500w comeon that is ludicrous
Meh perhaps I am wrong and you use suitable gauge coil but fog machines that fog whole stages are only 200-400watts..
Holy cow thats beyond hot lol
Just adding an opinion, you can get a 300 watt regulator that will give an honest 300+ watts they are not little but not so big..

As with almost all regs you can overdrive this one at 180% before it goes into protection mode so it will give ya 600 watts 120A easy.. I overdrive my smaller 10A
mod 20%-50% everyday no issues almost 3yrs service..
Someone has wired one up in this section if it interests you...
When I do dial up to 100w+ I blow
through the atomizer fogging my whole area. Really cool effects with light shows.. Its still hella hawt. lol
