I don't see any reason for that much power. First off, more power does not equal more vapor. What you want is temperature. I know I sound like a spokesperson for the DNA40, and I do love my DNA40, but it's true. More power will produce more heat, but it will also produce the toxic chemicals that e juice breaks down into when it is burned to that extent. Instead, by using a DNA40, you can set the temperature to a level that is safe, and still still get great flavor and vapor production. I'm sure some cloud chasers don't care about their juice breaking down, so long as they get those huge clouds, but for me, I picked up vaping to quick smoking. I now do it for the joy, but I still want to be safe. I love big clouds, but I love flavor more. Too hot of a hit is not fun to me.
