Joyetech’s website confirms this. However, it may be you can set it to output 200w, but I read somewhere that the reason the Reuleaux had 3 - 18650’s was that was needed to reach 200w and that 2 batteries can’t do it. I think in that same article or post it mentioned the max wattage 2 - 18650’s could produce was around 170. Not 100% sure of this but I know I read it somewhere. And if that’s true there will be some pissed off people who buy it based on their claims.
If 2 - 18650’s will produce 200 watts I’m sure someone will chime in.
