How to Find the Best RDA to Use With Your Mod

Green RDA

What Are RDA’s?

RDA, RTA, RBA, RPM, RNC…. acronyms have you confused? RDA stands for rebuildable dripping atomizer. Most smokers begin with a simple e-cig, and then they graduate from e-cigarette to vape pen. After they’ve enjoyed their pens they’ve moved on to mods, and then they’re still looking for something new. A rebuildable dripping atomizer is that next step.

They aren’t all that easy to build, but they offer unparalleled flavor and vapor production. Essentially, RDA’s have a coil or coils and a wick, but no tank. The vaper has to drip the e-juice directly onto the coil. The drip tip is shorter and narrower because you have to vape the liquid immediately after dripping it. You’ll generally have to drip more frequently, but the unparalleled flavor and vapor production make it totally worth it. The battery might not last as long either because RDA’s drain far more power than regular atomizers, but if you’re willing to sacrifice convenience for experience, then the RDA might be for you.

In this article, we’ll explain to you the kinds of RDA’s you can buy, how you calculate resistance and build coils, and what to search for when shopping for RDA’s. Then we’ll share all of our favorite RDA’s with you and explain what we like about them so much. So, if you want to know how to find the best RDA’s, then read on!

Why Use RDA’s Rather Than RTA’s?

RDA’s, as opposed to RTA’s, which are also known as rebuildable tank atomizers, do not have any tanks. RTA’s have a regular tank where e-liquid is stored. An RDA, on the other hand, has a deck with a number of posts supporting either one or two atomizer coils. The vape juice collects underneath the deck in a well, and with the help of airflow, the liquid is absorbed by the wick to be vaporized and inhaled.

What Kinds of RDA’s Are There?

RDA’s come in all sorts of shapes and sizes. They range in size all the way from a measly 14mm all the way to 46mm, and while most hold one or two coils, there are coils that hold up to six. You can find RDA’s in brass, copper, stainless steel, and other metals as well as a whole host of different colors. You can decide whether your atomizer will allow you to vape mouth-to-lungs or direct-to-lungs–RDA’s can do pretty much anything because, well, you build them.

RDA’s can, however, be classified as either suited better for cloud production or flavor production. Cloud-chasing destined atomizers will have a longer diameter, heavier coils, and a larger airflow. RDA’s meant to produce intense flavor tend not to exceed 22mm in diameter, have less airflow, and are intended for mouth-to-lungs vaping. Of course, the majority of RDA’s can perform both functions rather well, but if you’d like to maximize on one either flavor or taste, then you’ll want to look for these qualities specifically.

RDA’s are either three post, four post, or velocity style RDA’s. A three post RDA has one positively charged post in the center surrounded by two negatively charged posts on either side of it. The four post style functions much the same way except that the center post is split making it easier to attach two separate coils. The velocity style includes but two posts that can secure two separate coils at one time. Do make sure though that the RDA is meant to take multiple coils. It’s easy to confuse velocity RDA’s with standard single coil designs.

Lastly, RDA’s differ based on airflow styles. RDA’s will either have a series of horizontal airflow slots surrounding a single eye, hence the name ‘cyclops’. RDA’s with airflow vents on the bottom produce greatest flavor. Vent holes along the top of a device are most practical because they seldom spill or overflow. You can also find RDA’s that let air circulate through the bottom and then horizontally past the coils and even RDA’s that cause the air to swirl through like a vortex, which gives this atomizer its name.

After You Find the Best RDA, How Do You Calculate Resistance?

When you picked up your first starter kit, you probably popped in the atomizer and took a puff. Well, unfortunately, RDA’s aren’t that simple because you become responsible for keeping the resistance, voltage, and current all within reasonable limits. While RDA’s are perfectly safe, they can become quite dangerous if you fool around with equipment you don’t understand.

When first starting out, you’re probably not going to want to venture into sub-ohm terrain because if your resistance is too low, you risk letting your mod overheat. Vapers want low resistances when using mechanical mods, which can be even more dangerous because there are no regulations built into the system. Once you’ve built a fair amount of coils, you can start decreasing the resistance, but don’t go below 1.0Ω just yet.

You can test the resistance of the coils using an ohm reader. An ohm reader is an absolute must when it comes to RDA’s. You can find a digital volt-ohm reader over at ePuffer for testing atomizer coils and cartomizers to tell both when they’re ready to be used and when they’re ready to be tossed.

You’ll also want to do a few quick calculations to ensure that the mod you want to use is strong enough to handle your atomizer. Ohm’s law, you should recall, states that the current is equal to the voltage divided by the resistance, so the voltage of your battery divided by your resistance should never surpass the amperage capacity of your mod. Remember, the lower the resistance, the higher the current rate because the quotient increases when the divisor becomes a smaller and smaller fraction.

Criteria to help you to find the Best RDA

Number of Posts- RDA’s generally come with either two or three posts. There are RDA’s that come with more, but they’ll overheat too quickly. Plus, it’ll require you to make an absurd number of coils when fewer will suffice. Typically RDA’s with a split center post–four posts in total–generally prove to be the simplest because the coils don’t have to share the same hole. If there isn’t enough room on the posts, you’ll be placing too many coils into the same limited space.

Airflow Control-Airflow control plays a vital role in vaping with RDA’s because it has a massive impact on the flavor and vapor production. Especially if you’re sub-ohm vaping. The lower your resistance, the more airflow you need to get a direct-to-lungs hit. When shopping for RDA’s, make sure to find one with vents that allow air to blow through at multiple angles and an adjustable ring situated at the base of the atomizer so that vapers can adjust the amount of air going through at any given time.

Contact Pin-Contact pins connect the battery to the atomizer, so you’ll want to verify that the contact pin comes in a highly-conductive metal like silver, gold, or copper rather than bronze or stainless steel.

Tank Capacity- If you’re tank is too large, too much vapor will collect, but if your tank is too small, you won’t be able to vaporize liquid correctly. It’s best to pick a moderately-sized tank.
Aesthetics- Who wouldn’t want a beautiful RDA? None of us can resist one with beautiful curves and a healthy sheen to it.

Squonk Pins-A number of RDA’s have squonk pins. Squonk pins are pins with holes in them connected to tanks below the RDA. Instead of dripping, you can use the squonk pin to squirt juice from the tank onto the cotton. Squonk pins allow you to vape without dripping e-juice constantly. If you follow these six steps though, you should be able to find the best RDA in no time

#6: CSMNT | Cosmonaut RDA by District F5VE

District F5VE promises that, with this it, you’ll be able to puff clouds larger than you’ve ever seen before. This amazingly postless design has an unsurprisingly large stage and can therefore accommodate large quantities of dense cotton. The entire atomizer is plated in 24K gold for optimal conductivity. At 24mm, it sits comfortably atop most mods, and can be purchased in a bright stainless steel or matte black. Plus, special lead inserts make the Cosmonaut RDA compatible with any wire type.

#3: Digiflavor Pharaoh Dripper RDA by RiP Trippers

DigiFlavor and Rip Trippers collaborated to bring you one of the most anticipated RDA’s in the past couple of years. This behemoth with a 25mm diameter and 35mm height has been carefully crafted from the finest stainless steel. It can hold a stunning 3mL of vape juice, and with the drip tip prevents any of it from squirting back into your mouth. Customers were wowed by the performance but found that the dual Clapton coils tended to heat to the point where extra airflow would have added some relief.

I ordered this atomizer on pre-sale and had been waiting weeks to use it. When it finally came, it was all I was looking for and more. I typically carry at least 3mL with me, so I’m not sure the juice storage function is particularly helpful. In any case though, I love the flavor and the clouds. You want to find the best RDA? Here it is!
