Ok so I've been vaping for a long time, but I've never used a rda. But I'm about to get a dark horse or a mutation x v4 this Friday but I'm trying to figure out would a ipv mini 2(70w) be able to make some sick clouds with one of those rdas? I want a sigelei 150 but I dont have the money right now so I'm leaning towards the ipv mini. Thanks for the help! Also how many watts do you guys use your rdas at?
