What do you mean by stronger? More vape? If that is the case, then choosing one of the lower ohms, like the 0.6, is what you are looking for. As far as I know, there isn't a 0.4 or 0.5 ohm coil, but I've never used this model. If you are looking for a warmer vape, then there is a 1.4. You could try turning up the wattage, if you are not already at the highest setting (H), which is 30W. All in all, this is a limited beginning MTL
device for tootle puffers. It is a far cry from even other pods. If you have a 0.6 ohm coil, are on the highest watt setting, and have the air flow wide open, and you are still not getting enough vape or flavor, then it's time to upgrade your
device. Consider something like the Innokin Sceptre 2 or the Sensis. Try reading some
Reviews on pods that have more power (wattage capabilty) and take lower ohm coils. If you are looking for something that is DL then forego the pods altogether and go with a mod.
