I'm not 100% sure, but its my understanding that its regulated to around the same 2.5 amps as the LT is. Did you guys see PBusardos very in depth review on one of the lava tube rebrands? It was a something or other vv. But in that review, he charts out exactly how high you can take a carto/atty of 1.25, 1.5, 2, 3, 4 ohms in voltage and or where the safety features drop it down. It was exactly what I needed to see, so i could tell that for me, it won't drastically affect my vape. I vape mainly 2 and 3ohm boges, and 1.5 resurrectors, so it wasn't a huge concern for me.
I'm not 100% sure that the vision tox aka GS-Sub aka howitzer does the same thing, but it looks pretty similar in terms of safety functions, so guessing it does. Would I be happier if it let me push the voltage another .25v? Yup. But I'll be pretty darn satisfied as is. I don't use dual coils, though, so that makes a big difference.
