Vape Pens: Types, Uses, and How to Choose

“Vape pen” is one of the most confusing terms in the whole hobby, because it means several different devices depending on who’s saying it. To one person it’s a slim e-liquid vape; to another it’s a battery for cartridges; to another it’s a device for concentrates or dry herb. Buying the wrong type for what you want is the classic mistake. This guide clears it up — the main kinds of vape pen, what each is for, how to choose and use one, and how they stack up against pods and mods — so you walk in knowing exactly what to ask for.

We carry a range of pens and the gear that goes with them at Pomona Smoke N Vape, so here’s the plain-English breakdown.

What is a vape pen?

At its simplest, a vape pen is a slim, pen-shaped vaping device — longer and thinner than a boxy mod, designed to be portable and easy to hold. Beyond that shape, though, “vape pen” splits into distinct types based on what they vaporize. That’s the key thing to understand before you buy: the shape is similar, but the purpose varies, and a pen built for one material won’t properly handle another. Let’s go through the main kinds.

The main types of vape pen

E-liquid vape pens

These are slim devices that vaporize e-liquid, like a simplified, pen-shaped version of a pod or small mod. They typically use a refillable tank and a built-in battery, giving you a straightforward, portable e-liquid vape without the bulk of a box mod. They suit people who want something slim and simple for juice, and they overlap a lot with pod systems — in fact, many “pens” today are really pen-shaped pod devices. If e-liquid is what you want, our pods guide covers the closely related pod systems too.

510-thread batteries (cartridge pens)

These are simple battery devices with a standard “510” threaded connection that screws onto pre-filled cartridges. The pen is just the power source and draw mechanism; the cartridge holds the material. They’re popular for their simplicity — screw on a cartridge, inhale, done — and the 510 thread is a near-universal standard, so one battery works with many cartridges. Features vary from basic single-button or draw-activated units to ones with adjustable voltage for tuning the hit.

Concentrate and wax pens (dab pens)

These are built for concentrates rather than liquid — a pen with a chamber and a coil or heating element designed to vaporize wax and similar materials. They’re the portable, simpler cousin of a full dab rig, trading some performance for convenience and pocketability. If concentrates are your thing, our dab rigs and concentrates guide covers the whole category, including when a pen makes sense versus a rig.

Dry herb vape pens

These vaporize dry herb rather than liquid or concentrate, using a chamber that heats the material to produce vapor without combustion. They’re a portable option in the dry-herb world; larger and more powerful dry-herb options exist too. The key point is that a dry herb pen is a completely different device from an e-liquid pen — don’t expect one to do the other’s job.

Choosing the right vape pen

Because “vape pen” covers so much, choosing starts with one question: what do you want to vaporize? Get that right and the rest follows.

• E-liquid? Look at e-liquid pens or, often better, a pod system — slim, refillable, simple.
• Pre-filled cartridges? You want a 510-thread battery. Pick one with the features you want (basic or adjustable voltage).
• Concentrates/wax? You want a concentrate pen, or a full rig if you want more performance.
• Dry herb? You want a dry herb pen or vaporizer, which is its own category.

After the material, consider battery life (bigger battery, fewer charges), build quality, portability, and any adjustability you want. Don’t overbuy features you won’t use — a simple, well-made pen beats a complicated one you don’t understand. Tell us what you’re vaporizing and how you’ll use it, and we’ll point you to the right type. Browse options on our shop page.

How to use and charge a vape pen

Using a pen depends on its type, but the basics are consistent. Many pens are draw-activated (just inhale), while others have a button you press or hold while inhaling, often with five quick clicks to turn the device on or off. If a pen won’t fire, check whether it needs turning on and whether it’s charged. For e-liquid pens, you fill and prime the coil like any refillable device. For 510 batteries, you screw on a cartridge and go. For concentrate and dry-herb pens, you load the chamber as the device directs.

Charging follows the same safe rules as any vape: use a quality cable and a standard low-amp source, don’t charge unattended or overnight, unplug when done, and keep the device cool and dry while charging. Our complete how-to guide covers using, filling, priming, and charging in detail, which is worth a read whatever type of pen you have.

Coils, atomizers, and cartridges

The part that does the vaporizing wears out, and knowing which part yours uses helps you maintain it. E-liquid pens use coils that need replacing when flavor dulls or tastes burnt, and priming a new one is essential. 510 batteries don’t have their own coil — the cartridge contains everything, so you replace the cartridge. Concentrate pens use atomizers or coils designed for wax, which have their own lifespan and cleaning needs. Keeping spares of whatever your pen uses means a worn part never leaves you stuck.

Why “vape pen” means so many things

It’s worth understanding why one term got stretched across so many devices, because it explains the confusion you’ll run into when shopping. In the early days of vaping, the first popular personal devices were literally pen-shaped — slim cylinders that looked like a pen or a thick marker. “Vape pen” became the everyday name for that whole form factor. As the hobby grew and split into different materials — e-liquid, concentrates, dry herb, and pre-filled cartridges — the pen shape carried over into each, and people kept calling them all “vape pens.” So the term ended up describing a shape rather than a specific function, which is why asking for “a vape pen” without saying what you want to vaporize leaves a lot unspecified. The shape is the common thread; the purpose is what you actually need to pin down. Once you know that, the confusion disappears — you just specify the material and the right type becomes obvious.

Cartridge pens and voltage settings

For 510-thread cartridge batteries, one feature worth understanding is adjustable voltage, since it’s the main way these simple devices let you tune the experience. Basic batteries run at a fixed output — screw on a cartridge and inhale. Adjustable ones let you set the voltage up or down, which changes how hot the cartridge runs: lower voltage gives a cooler, more flavorful, more conservative hit, while higher voltage gives a warmer, bigger hit that uses the cartridge faster. The practical advice is to start low and work up, because running a cartridge too hot can scorch the material and give a harsh, burnt taste, while a lower setting preserves flavor and makes a cartridge last longer. If a cartridge tastes harsh or burnt, your voltage is likely too high. Many people find a middle setting works for most cartridges, and only adjust when something specifically calls for it. It’s a small feature, but it meaningfully changes the experience once you know how to use it.

Concentrate and dry-herb pens in a bit more detail

For concentrate pens, the heating element — often described by its material, like ceramic or quartz — shapes the experience, with different materials favoring flavor or intensity, and each needing regular cleaning as residue builds up. These pens trade the performance of a full rig for portability, which is the right call when you’re out and about but means a home rig will generally outperform them; our dab rigs guide covers when each makes sense.

Dry-herb pens heat the material in a chamber to produce vapor without burning it, and they come in styles that heat by direct contact or by hot air, each with its own feel. They’re a portable slice of the dry-herb world, with larger desktop and handheld vaporizers offering more power and consistency at home. The common thread with both concentrate and dry-herb pens is that regular chamber cleaning matters far more than with an e-liquid device, since residue directly affects flavor and performance.

Why the 510 standard matters

The “510” threading on cartridge batteries is one of the few genuine standards in vaping, and it’s quietly useful. Because so many batteries and cartridges share the 510 connection, a single battery you like will work with a wide range of cartridges, and you’re not locked into one brand’s ecosystem the way you are with pods. That interchangeability is a real convenience — you can replace a battery without replacing everything, and you have broad choice in what you screw onto it. It’s one of the main reasons the simple 510 battery remains so popular despite being one of the most basic devices out there. When buying a 510 battery, you’re mostly choosing on build quality, battery life, and whether you want voltage adjustment, knowing the connection itself will fit widely.

Vape pens vs. pods vs. mods

Where do pens fit against the other devices? For e-liquid, a “pen” and a “pod” heavily overlap — both are slim, simple, reusable devices, and the line between them is blurry; choose by which specific device suits you rather than the label. Against a box mod, a pen is slimmer, simpler, and more portable, but less powerful and less customizable — a mod wins on clouds and control, a pen wins on pocketability and ease. For cartridges, concentrates, or dry herb, a pen is often the most portable option in that category, with rigs and larger vaporizers offering more performance at home. The right choice is less about “pen vs. pod vs. mod” as categories and more about matching the device to the material and the simplicity-vs-power balance you want.

Caring for your vape pen

A little care keeps any pen working well. Keep the threads and connections clean — stray juice or residue there causes weak or inconsistent hits, especially on 510 batteries where a dirty connection is a common culprit. Change coils or atomizers before they fully fail, store the pen out of heat and upright where relevant, and keep the charging port clear. For concentrate and dry-herb pens, regular cleaning of the chamber matters more, since residue builds up and affects both flavor and performance. These habits take seconds and prevent most of the problems people blame on a “bad” pen.

Common vape pen problems and fixes

Most pen issues have simple causes. A pen that won’t fire may just need turning on (five clicks) or charging, or the connection may be dirty — a quick wipe of the threads often fixes a 510 battery. A burnt taste on an e-liquid pen usually means an unprimed or worn coil. Weak hits point to a low battery, a dirty connection, or a cartridge not screwed on fully. Leaking on an e-liquid pen often means overfilling or a juice mismatch. These cover most issues, and you can bring any pen into the shop and we’ll diagnose it quickly.

The legal basics

Vape pens and the products used in them are age-restricted. You must be 21 or older with a valid photo ID to buy, in-store and at delivery for online orders, and we card every customer. Availability of certain products varies with regulation and location, so buying from a shop that stays current matters. Nicotine products contain nicotine, which is addictive.

Portability, discretion, and battery life

The main reason people reach for a pen over a bulkier device is the form factor, and it’s worth being clear about what that gets you. A pen slips into a pocket or bag easily, is comfortable to hold, and draws less attention than a boxy mod — which is why pens remain popular for people who want something low-profile and on-the-go. The trade-off for that slim shape is battery life: a thin device has less room for a battery, so pens generally need charging more often than a chunky mod with a big cell. If you’re out all day, that’s worth planning for — either choose a pen with a larger battery, or keep a charging option handy. For cartridge batteries especially, a dead battery mid-day is a common annoyance, so topping up before you head out is a good habit. None of this is a dealbreaker; it’s just the natural trade between portability and run time, and knowing it helps you pick a pen that fits your day rather than fighting it.

Buying authentic pens and cartridges

As with every category in vaping, authenticity matters, and the simplicity of pens doesn’t exempt them. Counterfeit batteries and low-quality devices exist, and a cheap, poorly made pen can underperform or raise safety concerns, particularly around the battery. The protections are the same as anywhere: be wary of prices far below the norm, buy from a shop that sources through legitimate channels, and check build quality — a device that feels flimsy or hollow is a reason to pause. For cartridge pens, pairing a quality battery with legitimate cartridges gives the best and safest results. Buying from a reputable local shop means the pen you get is a real, functioning device rather than a convincing-looking knock-off, and someone can show you how to use it properly before you leave.

Frequently asked questions

What is a vape pen?

A slim, pen-shaped vaping device. The term covers several types depending on what they vaporize — e-liquid, pre-filled cartridges, concentrates, or dry herb — so “vape pen” alone doesn’t tell you the whole story. Start by deciding what you want to vaporize.

What’s the difference between a vape pen and a pod?

For e-liquid, they heavily overlap — both are slim, simple, reusable devices. Choose by the specific device that suits you rather than the label. Many “pens” today are really pen-shaped pod devices.

What is a 510-thread battery?

A simple battery device with a standard threaded connection that screws onto pre-filled cartridges. The pen provides power and draw; the cartridge holds the material. The 510 thread is a near-universal standard.

Can one vape pen do e-liquid, concentrates, and dry herb?

Generally no. These are different device types designed for different materials. Some multi-use devices exist with swappable attachments, but a pen built for one material usually won’t properly handle another.

Why won’t my vape pen turn on or hit?

Try five quick clicks to switch it on, make sure it’s charged, and wipe the threads or connection, which often fixes a 510 battery. On e-liquid pens, check the coil is primed and seated.

How do I charge a vape pen?

Use a quality cable and a standard low-amp source, charge it while you’re around rather than overnight, unplug when done, and don’t charge a hot or wet device.

The bottom line

The secret to buying a vape pen is realizing the term covers several different devices — so decide what you want to vaporize first, then pick the pen built for it. E-liquid, cartridges, concentrates, and dry herb each have their own type, and matching the device to the material is what prevents a disappointing purchase.
