Using an RDA can be more complicated than using an RTA because it requires a little more effort in setting up with a replaceable coil. But needless to say, all the hard work is worth it when it comes to the flavor and convenience after the first set up.

The atomizer has a coil that is powered by the battery. The coil heats up and warms the e-liquid. Once this liquid becomes hot enough, it will reach its vaporization point and turn into the vapor that you see coming out of the electronic cigarette.

The atomizer has a soft wick on it that absorbs the liquid and helps regulate how much liquid is permitted near the coil at once. This ensures that not too much vapor is being produced and that the liquid burns at a reasonable rate to allow for lengthy vaping sessions. This is called “dripping”.

Many vapers, especially beginners are having a hard time to wick atomizers. Although the process may seem a little bit overwhelming and difficult, the results, if done properly, should make the next few puffs so much worth it.

Some may wonder, “What’s the best way do do it?” The answer? Whatever floats your boat. There is no wrong way to wick a coil, so long as it works for you. But, if you want to do it on the easiest route, here are some steps and guidelines you can follow.

First, prepare the materials you will need:

• Cotton Pads

• Scissors

Step 1: Prep the cotton

Take whatever cotton you're using, whether it's cotton pads or Cotton Bacon, and cut/tear the piece you're going to use for your coils off. The width or thickness of the piece should be about the same as the width/diameter of the coils. Create two pieces.

You should take one and slide it through one coil. Roll the first end of the cotton until it's a small tip to make it much easier to pull through the coil. Afterwards, pull the cotton through until the coil is sitting about halfway along the length of the piece of cotton.

Step 2: Make the cut

This can be the tricky part. Where should you cut the cotton? Sometimes, people screw this part and repeat the process from the top. So, you need to take your time and be patient.

Remember that you want just enough cotton to plug up the juice channels completely, but not so much that there's cotton sticking all the way down them. As a general rule, line up the scissors with the bottom threads on the base of the tank. If you're using a thinner juice, like a 70/30 VG/PG ratio juice, you can afford to use a little more cotton, but if you're using a high VG ratio (80/20 or more), you'll want to use the least amount of cotton possible. Keep in mind that if you use too much, you'll end up getting dry hits because it won't wick fast enough.

Step 3: Spread and roll

Once you have that piece of cotton, spread it out across your work area perpendicular to the grain of the cotton. Once it's spread out thin and almost sheer, take one edge of your cotton and slowly roll it onto itself.

The roll should not be too tight, as the point of this method is to make your wick as fluffy as possible. You also don't want to roll it too loose, or else it may end up looking like a ball.

Step 4: Tuck into juice channels

Cut the rolled cotton into two equal pieces. Tuck the cotton pieces down into the juice channels. Most RTAs come with a retainer ring, which you can choose to use or not use; it's all up to you. Using the ring is especially helpful if you want to run a higher VG juice, since it's going to be more difficult positioning the short wicks by hand

Step 5: Double check

After these steps, make sure that the channels are completely covered up by cotton, but there is also no excess bits hanging down. The important thing to remember is not to jam a ton of cotton down those channels. You will get dry hits repeatedly.
