Smok V8 baby coil 0.4 ohm issues

[Andy S]

Hello all

New to this site trying to get some info.

I'm using smok V8 baby coils 0.4 ohm and I'm finding they only last a few days. When I've looked on the smok website says they should last a least a week. I'm not a heavy vapour and the wattage I'm using is relative low. I also find the cotton in the coils go black very quickly. I'm using a cool fire IV battery and I've only had this for less than a year. I charge it up fully but find it won't last a day. It's certainly got worse over time. Anyone any ideas how long these battery's should last? Can anyone provide any assistance please? Many thanks in advance.

The .4 Q2 isn't a great coil (although the 0.6Ω version is better IMNVHO.)
The NRG GT2 coil has the same resistance and power range as the Baby Q2 and lasts significantly longer. There are several other compatible coils but that's the only one I've used as I find it adequate for my needs.
