If you are familiar with the term RDA, then you are probably familiar with the term RBA. However, what are the differences, and what is an RDA? An RDA is short for Rebuildable Dripping Atomizer, and RBA is short for Rebuildable Atomizer. The RDA is where the e-liquid drips directly onto the coil or the wick. It does not hold much of the liquid at one time. You will have to fill the fluid more often. However, it is easier to make these and change the coils, the wicks, and even customize the output. The RBA holds more liquid; however, changing the wicks can be challenging.
By far, the better way to go is by looking into getting a rebuildable dripping atomizer. By using this RDA, you are not limited by what you can build since there is no resistance to limits. You'll not have to worry about the fragile devices that are always breaking and costing money. The components of this RDA include:
- a metal tube
- Firing Button
- Top Pin
There is basically nothing that can break on the RDA. There are many kinds on the market, which is included in this guide. The RDAs come in three different styles. There is a simple single coil that has two post atomizers, which are a negative post and a positive post. The most common form of RDS is the three-post atomizer. It includes two negative posts and has one positive pot. There is also four and five post RDSs. The five post RDA is a great option for those just starting out with the RDAs.
There are some downsides to using the rebuildable dripping atomizers; however, the positives of the RDAs by far outweigh them. One of them is that the battery may not last as long as you are used to. It can be easily solved by having another battery or charging it a bit more often. It is so small that it really should not classify as a downside, but a guide is honest and informative.
List of the Best RDAs
Before moving onto the list, you should be aware of the Ohm law. The ohm law states that a current that goes through a conductor between two different points is proportional to the voltage that is between the two points. Therefore, it is why when rebuilding the atomizer; it is crucial to ensure that you have an ohm meter. However, if you do not have an ohm meter, it is highly suggested to purchase one before attempting to rebuild the atomizers. There are a couple of the RDAs that are listed here that are purely for those who are familiar with RDAs and the ohm law. They are specified in the list.

This guide has been written in the hopes that it makes it easier for you to understand the options available when you are embarking on your journey of switching to E-Cigs from smoking cigarettes, as well as rebuilding atomizers (for ones that offer that option). We’ve also put together the reviews of some of the very best RDAs, so you can easily choose one that fits your bill.
How to Rebuild an RDA
In this walkthrough, we'll be going through how to rebuild an RDA that has three posts. There is one positive post that is in the middle, and then there are two negative posts that are on the sides of the positive post. Here are the materials that you will need to rebuild your three posts RDA.
- Kanthal - 28g
- Micro Screwdriver - 5/64
- Rebuildable Dripping Atomizer
- Ohm Meter
- Advanced E-Cig
The rebuildable atomizers are geared towards the advanced E-Cigs that offer high wattage. The regular pen type of E-Cig will not be able to keep up with this type of atomizer. The Mech mod or a higher wattage mod will be needed. Here are the steps to rebuild your RDA.
- You will first unscrew the screws on each of the posts. Ensure that you do not remove them. Unscrew them just enough so that the holes are visible.
- Wrap your coil using the kanthal.
- Hold one end of the kanthal with the thumb and the forefinger. Tightly wind the coil around the micro screwdriver. Wrap it around eight times or more, but no less than eight times. If the kanthal overlaps, you will need to start again. If the coil is not tight enough, do not worry about this now.
- Insert two ends of your coil into one side of your RDA. It will be much easier if you leave your screwdriver in as you put it in.
- Repeat the steps and ensure that you wrap the coil the same amount of times.
- Clip off your ends.
- Put your atomizer on the ohmmeter to get the resistance. Depending on the device, it will rely on the range that is acceptable. It will be from 0.5 to 1.0 ohms. If one coil is a bit tighter than the other, this is all right.
- Put your RDA on the mod and fire it. Make sure that it is not set to high. Squeeze the coils between the firings. Squeeze the coils between firings so that you can get them to the same size.
- Put a strand of cotton into one of the sides.
- Repeat this for the other size. The cotton should not be too tight. It will expand when saturated.
- Cut off the ends of the cotton.
- Drip in your liquid. Test the E-Cig. Make sure to clean up the kanthal as it will pierce the skin if you step on it.
