Hi folks. Iv been vaping for over a year now and iv tried various different tanks, clearo's and cartos but recently just purchased myself a new Aerotank by KangerTech which i have atop my ITaste MVP v2. To start with on the first night using it, at 10W the vape+flavour was great and was gettin a great throat hit but after a while, after a couple of nice puffs I was gettin a slight burnt taste. I would leave it sittin a while then try again, same thing would happen, first couple of puffs was good but then the burnt taste would come back. Now the strange bit, after a few days and coils later and different setting changes, I now find that vaping at just 7W through the Aerotank im getting Great vapor, throat hit and flavour and its been a couple of days at that setting. What I dont get is the coils I use are official Kanger Protank3/Aerotank dual coil heads at 2.0ohms which I though could withstand a good kick at between 8-10W but is better at just 7W. I thought Dual coils could take the heat?
