the ohm on the
tank replacement coils , what difference does it make?
If you're using a mech mod (just a battery in a tube) or a non-adjustable battery (like a simple ego) the lower-resistance coils will give you a warmer vape (or even a very hot vape, which you don't want) but will also produce more vapor. Higher resistances will provide a cooler, but thinner vape.
With a regulated mod (either VV or VW) there is less of a difference, and often using a higher resistance coil will give you more range to work with. If you''re starting out with a VV/VW mod try heads in the 1.8-2.5 ohm range to start with.
There are some sub-ohm heads (resistances less than 1 ohm; some go down to 0.5 or even 0.3) but these require that your mod can fire them; many regulated mods can't go below 1 ohm or thereabouts; you need a high-power mod to use these coils. And if you're using them in a mech mod you
really need to learn about battery safety!!!
