Chapter 4


ch4-blog-notext_02 What better way to follow a chapter about rebuildable atomizers than to discuss how to build a coil for these types of atomizers!!Building your coils can be difficult at first, but don’t worry. Just like everything else, practice makes perfect. The best thing about knowing how to build your own coils is, it’s convenient! And in all reality, saves you lots of money.

A coil is the wire that is connected to the base, which in turn is connected to the battery or mod. When the battery is powered, the wires heat up and turn the e-liquid into vapor. Without a coil, there’s nothing to produce vapor. Coils are predominantly made with kanthal but can also be made with nickel or titanium depending on your personal preference. Nickel and titanium wire are only used for building when you’re attaching it to a mod that has temperature control functionality.

Building is the verb used when making a coil. This is done by wrapping wire tightly around a screwdriver to form a coil. Building coils take time and patience so don’t get frustrated when the first few don’t come out too good looking. The most important aspect when it comes to building is knowing build safety. If you’re building for a regulated mod, the manual that comes in the box will tell you the minimum resistance for that particular mod. You’re probably asking, what makes the difference in resistance when building a coil. The answer to that is what size screwdriver your using, what gauge wire, as well as how many wraps. The less wraps, the lower the resistance.

A wick is just the material inside a coil to hold and deliver e-liquid. This is usually made from cotton but can also be made with silica or mesh depending on what atomizer you’re using. Using mesh is mainly for building on genesis style atomizers.


What you’ll need:

  • Kanthal wire
  • 2mm Screwdriver (most rebuildable atomizers come with one)
  • Additional screwdriver or allen key that fits your atomizer screws
  • Needle nose pliers
  • Wire cutters
  • Scissors
  • Organic cotton
  • E-liquid

Wrapping Your Coil

Step 1: You’ll need about 3-4 in. of wire to build one coil. Place the wire above the 2mm screwdriver as close to the handle as possible and hold it firmly with your thumb.

Step 2: Then you want to start wrapping your coil until you’ve reached the desired number of wraps. You want the wraps to be as close together as possible without overlapping.

Step 3: Once you’ve reached the desired number of wraps, both leads should be facing the same direction.

Installing Your Coil:

Step 1: Take the deck of your RDA and loosen the screws just enough so that the wires can fit through. You don’t want to take the screws completely out because they’re easy to lose and hard to put back in when you’ve only got one free hand.

Step 2: Then with your coil still around the screwdriver, put one lead through the negative and the other through the positive.

Step 3: Try to position your coil towards the center of the deck. Once you’ve got it centered, you can now tighten your screws. Be careful not to tighten them too much because you could cut the wire and have to start all over.

Step 4: Now that you’ve tightened your screws, you can carefully position your coil more towards the center if it isn’t already by moving the screwdriver in whichever direction needed. Once you’re satisfied with this step, you can now remove the screwdriver and cut the extra wire off so that the leads are as close to the negative/positive posts as possible.

Eliminating Any Hotspots:

Briefly fire your mod until your coil is completely lit. Once your coil is lit, let go of the fire button and compress your coils with the pliers. Repeat this step until your coil lights up evenly from the center towards the outer wraps. Another way is to stroke the coils with a pair of tweezers. Once your coils light up evenly from the inside out, you’re all set to move on to the next step.

Wicking Your Coil:

Step 1: You want a piece of cotton that can fit snug inside of your coil, not to lose and not too tight.  Make sure that there is enough cotton that when folded, it can reach the bottom of the deck.

Step 2: Tuck the cotton under your coil.

Priming Your Cotton:

Simply saturate your cotton with your favorite juice, making sure to go over the coil so that the cotton inside is also saturated. Then place your RDA sleeve onto your deck and repeatedly fire your mod until your cotton is dried out but not burnt. Once you’ve done that place your cap back on, add more of your favorite juice, and vape on!
