Do I have smok al85 and I need a different tank because the one that was on it when I bought it didn't work. So I live above a smoke shop and the guy down there obviously has no idea what he's talking about I don't think. He had me by for $50 a tfv18 mini tank for my al85 mod and blue raspberry lemon flavored 6 mg nicotine 100 ml bottle from cloud nurdz for some reason I still cannot get my vape to fire it is driving me nuts can anybody please help me
1st guess: The TFV18 coils are low Ohm & require high power. The AL85 is a single 18650 mod. Your battery may not be able to output enough power for the coil.
Even if you have a high CDR battery, you're not going to get much use out of it at the recommended wattage for TFV18 coils.
Some more info about your battery & the coil you've installed & your mod settings & what it's doing/not doing (like, is there a message appearing on the screen when you press the fire button) would be useful to help you more. It's likely, though, that the vape shop employee (like most of them these days) was clueless & sold you a tank that's not really suitable for your mod.
2nd guess: Your mod is on it's last legs.
