The coil is essentially a resistor through which your battery module passes an electric current to superheat the vape juice into vapor. The thickness and material of the coil determine the resistance of the coil through the law of resistance — but let’s not worry too much about that.
Coil material, structure and thickness all change the dynamic characteristics of a particular coil. This means that there are several factors that determine how good a coil is for your particular goal.
Common coil is a certain length of wire coiled into a spring shape. There are many different types of conventional coils, ranging from simple circular coils to coils that use multiple wires to form a single strand.

E-liquids last longer and longer than when using mesh coils
Easy to build and install
Faster burning rate
May not be consistent
The startup speed is slow
Batteries may be heavier
Arguably not as tasty as a mesh coil
There are some differences between ordinary coils and mesh coils, but the most obvious difference is that mesh coils are usually not coil spring shaped. They are usually ultrathin wire mesh sheets that are then bent over your wick.
Mesh coils are designed to have similar resistance to ordinary coils, but still heat evenly. The meshing structure also means that they heat up (heat up) faster, making them more sensitive than normal coils.
Because mesh coils have a larger surface area of the coil in contact with the wick, they generally produce more steam and a better flavor than normal coils.
Pros: Thick cloud cover, excellent flavor (more surface area to evaporate juice), longer service life, less dry burning (if installed correctly)
Cons: Too much steam, large consumption of e-liquids, more difficult to install properly, fragile
The biggest difference between regular and grid comes down to how they draw energy from your mod and convert electricity into steam.
Mesh coils provide a larger heating surface area and a larger cloud without high wattage.
Conventional coils, on the other hand, essentially force their way into large clouds. They compensate for the smaller surface area by increasing the number of coils and the power input.
