My coils have been giving out really fast. My brother says you have to break in your coils. I vape at around 20 watts. Where should I start at? And how should I move it up in wattage and how fast? Thanks in advance for any help.
Not exactly sure what your Brother means by "Breaking In" a coil?
When I start using a New Coil, I like to Dial Back the Wattage a tad to make sure the Coil is working like it should. And that the Wicking is Wicking right.
If I Normally vaped at 20 Watts for a given Coil, I might do the first Couple of hits at 15w or so. If All is good, I might go to 17.5w. Then go to 20w. From there, I adjust the Wattage either Up or Down to find the Sweet Spot.
It's not really an Exact Science. But it can minimize the Chances of getting a Dry Hit/Burnt Cotton right out of the gate.
