An atomizer is the part of any vape that turns e-liquid into vapor: a heating coil plus a wick. A clearomizer is a clear tank with a replaceable atomizer coil inside, the ancestor of today's vape tanks. A cartomizer combines the cartridge and atomizer in one sealed tube, usually with a filler material instead of a wick, and was mostly used in early cigarette-style e-cigs. So every cartomizer and clearomizer is a type of atomizer, but not every atomizer is a cartomizer or clearomizer.
These terms come up constantly when you start vaping, and they're easy to mix up. This guide explains each one, how it works, and where it fits next to the tanks and pods sold today.
What Are Atomizers, Clearomizers and Cartomizers?
- Atomizers: What is an atomizer? It's the component that heats e-juice into a fine vapor so you can inhale it. Cartomizers and clearomizers are technically atomizers too, but when vapers say "atomizer" they usually mean a rebuildable one that you build and wick yourself.
- Clearomizers: A clearomizer is a see-through glass or plastic tank that holds a premade, replaceable atomizer coil. You can see how much liquid is left, and you swap the coil when it wears out.
- Cartomizers: A cartomizer, sometimes called an "extended atomizer," is a cartridge and atomizer in one longer tube. Cartomizers were typical of early e-cigs designed to look like cigarettes and are rarely used today.
| Rebuildable atomizer | Clearomizer | Cartomizer | |
|---|---|---|---|
| What it is | A deck you build coils and wicks on (RDA, RTA) | Clear tank with a replaceable prebuilt coil | Cartridge and atomizer in one tube |
| Coil | Built by you | Replaceable coil head | Built in; replace the whole cartomizer |
| Liquid storage | Dripped onto the wick (RDA) or held in a tank (RTA) | Visible tank | Filler material inside the tube |
| Effort | High | Low | Very low |
| Today's equivalent | RDAs and RTAs | Sub-ohm and MTL tanks | Prefilled pods and cartridges |
How Does Each One Work?
Using an RDA atomizer lets you drip your own juice onto the wick, which suits vapers who enjoy tinkering to find the perfect experience. It takes some knowledge and practice, though, and it's not easy on the move because you need to re-drip every few puffs. That's where a good vape tank comes into its own: it lets you vape anywhere without any tinkering. Even experienced drippers keep a few tanks on standby for days out and save the RDA for home.
Atomizers
When most vapers talk about atomizers, they mean rebuildable dripping atomizers (RDAs) or rebuildable tank atomizers (RTAs). On these, you install your own coil (one or two), thread cotton wick through it, and add e-liquid. When you fire the device, the coil heats and turns the soaked wick's liquid into vapor. Rebuildables need more frequent filling and more maintenance, but many enthusiasts like the flavor and control they give. If you want to try it, our guide on building coils and the parts you need is a good place to start.
Clearomizers
Clearomizers were a popular choice for newer vapers because they need far less work. The coil is a self-contained head that screws into the tank and can be replaced in seconds. Early clearomizers put the coil at the top or bottom of the tank; modern tanks almost all use replaceable bottom coil heads. The VAPORESSO iTank T is a current example: a top-fill tank that takes the full range of GTi coil heads.
Cartomizers
Cartomizers were intended as "one-and-done" parts. They could be refilled, but it was rarely worth the effort, and when they were finished users threw them away. The idea lives on in today's pods: a refillable pod such as the XROS POD holds e-liquid and a built-in coil in one piece, and you replace the whole pod when the coil wears out.
What Are the Benefits of Each Device?
Each has pros and cons, so the right choice depends on the kind of vaping experience you want.
Atomizers
As you become a more experienced vaper, you might try an RDA or RTA. They offer the most control and the most personal setup. If you're brand new or not technically inclined, a rebuildable isn't the place to start, but if you enjoy the hobby side of vaping, it can be rewarding.
Pros
- High level of customization
- Strong, clean flavor when built well
- Lower ongoing cost: wire and cotton cost less than coil heads
Cons
- Frequent refilling (especially RDAs)
- Complicated for beginners; you need to understand coil resistance and battery limits
- More chances for mess
Clearomizers
Clearomizers, now usually just called tanks, are a good place to start if you want a refillable setup that's easy to live with. They balance ease of use with a good vaping experience, and many accept several coil resistances, so you can change from a tight draw to a looser one as your taste develops.
Pros
- Large juice capacity and fewer refills
- Coils swap in seconds
- Many coil options for different vaping styles
Cons
- Coil choices can be confusing at first
- Glass sections can crack if dropped
- Previous e-juice flavors may linger until the coil is changed
Cartomizers
Classic cartomizers are outdated, but the convenience behind them hasn't gone away: prefilled cartridges and pods follow the same idea of an all-in-one part you replace rather than maintain.
Pros
- Similar hand and mouth feel to cigarettes
- Nothing to build or maintain
- Often prefilled
Cons
- Polyfill filler dulls flavor
- Not easy to refill or reuse
- Limited flavor range and not ideal for heavy use
Let's Recap
The right choice comes down to your preferences, skill level and expectations. Rebuildable atomizers give the most control but have a learning curve; tanks (clearomizers) are the easy everyday option; cartomizers have largely been replaced by pods. If you're still unsure, start with a tank or a refillable pod and try a rebuildable later.
FAQ
What Is a Cartomizer?
A cartomizer is a combined cartridge and atomizer in one tube, with a filler material that holds the e-liquid around the coil. It was common in early cigarette-style e-cigs and is replaced as a whole when it wears out.
What Is a Clearomizer?
A clearomizer is a clear tank with a replaceable atomizer coil inside. Modern vape tanks are its descendants.
Is a Pod the Same as a Cartomizer?
Not exactly, but they're related. Both hold e-liquid and a coil in one replaceable part. Pods are newer, usually refillable, and use a wick and modern coils rather than filler material.
Is an Atomizer the Same as a Coil?
The coil is the heating part inside the atomizer. "Atomizer" covers the whole assembly that turns liquid into vapor: coil, wick and the housing or deck around them.
