For setting up in wattage mode, it's pretty much the same for all mods.
For coils under 1 ohm, I start around 10watts and slowly increase until I get a vape I like. You'll get a burnt taste if you go too high, back down half a watt or so and you have the sweet spot for that juice. As an example I run .5ohm coils around 25 watts. Sometimes a little higher sometimes a little lower, depending on the juice. Then there are a few juices I get on occasion that I will run as high as 45 watts.
There is no magic setting that a specific mod will run at, just a ball park.
