I push about 45 watts out of my Reo Grand at .39 ohms. Thats factoring for the voltage drop being 3.8-3.9 volts all things considered. My stingray will hit harder, but I use that at home with a Caterpillar rda which honestly winds up being too messy for out and about. Certainly one of the messier drippers I've used, but a terrific vape. I was very happy with my Provari and RSST for quite a while, but I found dripper and mechanicals and finally my Reo and couldn't be happier.
