How does a dripper work in everyday use?

You open the top cap, add 5 to 10 drops of e-liquid to the coil and cotton, close the atomiser and vape. Depending on the build, a few puffs are enough before you need to add more e-liquid. That may sound like a lot of effort, but in return it delivers a flavour intensity that pre-built coils rarely achieve. Typical use cases Flavour testing: Perfect for comparing different e-liquids one after the other, as you can change the cotton quickly. Cloud chasing: Thick wire combinations at 0.1–0.3 ohms produce large amounts of vapour on a powerful mod. Squonking: With a BF pin hole, you can feed the RDA via a bottle in the mod – on the go and without constant dripping. Technical specifications Depending on the coil configuration, you’ll typically operate between 40 and 120 watts. Single-coil setups often run at 45–70 W, dual-coil builds at 70–110 W. The airflow is usually very open, which favours direct-to-lung (DTL) vaping.

RDA - Rebuildable Dripping Atomiser explained in detail

Q: What exactly is an RDA?

The abbreviation RDA stands for Rebuildable Dripping Atomizer. Unlike pod systems or classic sub-ohm tanks, an RDA has no e-liquid reservoir. Instead, you apply a few drops of e-liquid directly onto the coils and the surrounding cotton, which channels the flavour into the so-called juice well. An RDA consists of just a few components: a deck with posts (mounting points for the wires), a chimney, a top cap with a drip tip, and an adjustable airflow. You build your own coils, cut the cotton to size and place it in the juice well. This design ensures an extremely direct vapour path from the coil to the mouth – hence the intense flavour. Distinction: An RTA (Rebuildable Tank Atomizer) has a tank, whilst an RDTA combines a dripper and a tank. The pure dripper remains the most minimalist form and is frequently used in squonker mode, where the e-liquid is pushed up from below through the 510 thread.

RDA guide: How the rebuildable dripping atomiser works, what to look out for when buying and how to wind the dripper correctly. Find out more now.

An RDA is a rebuildable atomiser where you drip the e-liquid directly onto the cotton – without a tank. Anyone looking for intense flavour, thick clouds of vapour and full control over their setup will eventually end up with this type of device. This guide explains what lies behind the Rebuildable Dripping Atomizer, how it differs from other atomisers, and what you should look out for before buying an RDA. You’ll also get specific tips on coil building, cotton and airflow, so that your first dripping atomiser really delivers.

Flavour testing: Perfect for comparing different e-liquids one after the other, as you can change the cotton quickly.

Technical specifications

Depending on the coil configuration, you’ll typically operate between 40 and 120 watts. Single-coil setups often run at 45–70 W, dual-coil builds at 70–110 W. The airflow is usually very open, which favours direct-to-lung (DTL) vaping.

Not every dripper suits every setup. The following points will help you choose:

Deck type: Postless decks and clamp decks make it easier for beginners to secure the wires, whilst classic two-post decks offer more flexibility for complex builds.
Diameter: 22 mm looks understated and suits smaller mods; 24–25 mm is standard; from 28 mm upwards, it becomes interesting for flavour and large coils.
Single or dual coil: Beginners are better off with single-coil RDAs – less material, simpler winding, lower battery consumption.
BF pin: If you plan to squonk later on, make sure a BF pin is included in the package.
Airflow design: Side, angled or bottom airflow significantly affect flavour and draw resistance. Side airflow often delivers the most flavourful vaping experience.

Common mistakes: cotton packed too tightly (dry hits), cotton too loose (leaks), coils too close to the deck (short circuit) or incorrect resistance for the battery used. An ohmmeter and basic knowledge of battery safety are essential – RDAs are almost always used with adjustable mods fitted with fresh, high-current cells.

Is an RDA suitable for beginners?

To a certain extent. Anyone willing to familiarise themselves with coil building, Ohm’s law and battery safety can get started straight away. Without these basics, a pod system or a pre-built coil vape is the more sensible way to start.

How long does a coil last in a dripper?

Depending on the e-liquid and vapour production, between one and two weeks. You’ll need to change the cotton more frequently – usually every few days, as soon as the flavour starts to fade or residue builds up on the coil.

Which wire is suitable for RDAs?

Kanthal A1 is robust and affordable, Nichrome heats up faster. Both work in wattage mode. Temperature control modes require special wires such as Ni200 or SS316 – check for compatibility with your mod.

How much e-liquid does an RDA use?

Significantly more than a pod system. With dual-coil builds at 80–100 watts, 10 ml per day is a realistic estimate. Plan your supply of suitable e-liquids accordingly.

An RDA rewards you with maximum flavour and full control over your setup – but requires practice, tools and battery safety. If you’re prepared to wrap coils yourself and change the cotton regularly, you’ll find that the dripper offers one of the most aromatic vaping experiences around.
