If you buy pre-filled cartridges, you need a 510 battery. If you buy concentrate like wax, rosin, shatter, or badder, you need a dab pen or a wax pen, which are almost always the same device under two different names. Here's how to tell the three apart and figure out which one actually matches what you're vaping.
The short answer
| Device |
What it works with |
Who it suits |
| 510 Battery | Pre-filled cartridges | Dispensary cart buyers who want the simplest setup |
| Wax or dab pen | Loose concentrate: wax, shatter, badder, rosin, etc | Concentrate users who want more control over flavor and heat |
| Combo device | Both, with swappable atomizers | Someone who regularly uses both formats and doesn't mind a compromise on each |
What is a 510 battery?
510 refers to the thread size on the connection, not a brand. It's the industry standard thread pattery, which is why a 510 battery works with cartridges from a wide range of brands rather than being locked into one manufacturer.
A 510 battery only works with pre-filled cartridges. It has no chamber for loose concentrate (nowhere to load a dab), and no way to heat wax directly. Most models offer a few voltage settings, and voltage is what changes how much vapor and flavor you get from a given cart. Lower voltage tends to preserve flavor and produce a gentler hit. Higher voltage produces bigger clouds and pulls more oil per hit, which also means the cart runs out faster.
This is the device for someone who buys carts at a dispensary and wants to press a button and go. There's no loading, no cleaning a chamber, and very little upkeep beyond charging it and screwing on a new cart when they old one's empty.
What is a wax pen?
A wax pen has a small chamber, called an atomizer, with a coil inside that heats loose concentrate directly. You load a small amount of wax into that chamber with a dab tool, and the coil vaporizes it on contact.
Coil material matters here more than it does with a cart. Quartz and ceramic coils are common, and each heats slightly differently, which affects flavor and how much concentrate you can load at once.
Upkeep is real with a wax pen in a way it isn't with a 510 battery. Coils wear out and need replacing every few weeks to a couple of months depending on how often you use it, and the chamber needs occasional cleaning to keep residue from building up.
This is the device for someone who buys concentrate rather than pre-filled carts and wants more control over exactly how much they're using and how it tastes.
Is a dab pen different from a wax pen?
Not really. In most day-to-day use, dab pen and wax pen describe the same category of device: something with an atomizer chamber built to vaporize loose concentrate.
Where the terms diverge a little is at the high end. Some people reserve "dab pen" for portable devices that more closely mimic a traditional dab rig, sometimes with e-nail style heating elements, where "wax pen" gets used more broadly for any concentrate vaporizer. In practice, most people and most retailers use the two terms interchangeably, and the inconsistency across the industry is more about marketing language than any real technical split.
If you're shopping and see both terms used for what looks like the same device, that's normal. They're pointing at the same thing.

Which one should you choose?
If you buy pre-filled cartridges, a 510 battery is the only device that fits. There's no reason to overcomplicate this one.
If you buy jars, buckets, or other forms of concentrate, a wax or dab pen is built exactly for that. Look for one with a replacable coil so you're not replacing the whole device when the atomizer wears out.
If you're buying your first device, start with whichever matches what you're actually buying at the dispensary right now. A cart buyer doesn't need to learn concentrate loading, and a concentrate buyer doesn't need a device that can't touch what they've already got.
Can one device do both?
Some batteries are built to accept both a 510 cartridge and a separate concentrate atomizer, usually sold together as a kit or as add-on attachments. These exist, and they work. The only one that truly meets our standards is the Duplex 2, which has special IntelliThread technology to change the device's resistance based on what's attached (a cart, the concentrate bucket, or the XL nectar tip).
The honest limit is that sharing one battery across both formats means neither one gets a setup fully optimized for it. A dedicated 510 battery is tuned for cart voltage curves. A dedicated wax pen's coil and chamber are built around loose concentrate specifically. A combo device sits in the middle of both, which is a reasonable trade for someone who genuinely uses both formats, but not the top pick for someone focused on just one.
To directly answer a common question: no, you can't put wax directly in most 510 batteries. They don't have a chamber or coil built for it, and trying to improvise one is a good way to damage the device.
What to look for whichever you pick
Build quality and materials matter more than most people expect going in. Well-made contacts and threading mean fewer connection issues down the road.
Variable voltage or preset heat settings give you more control over flavor and vapor production, which matters more as you get more particular about your experience.
Charging type and charge time affect how the device fits into your dab. USB-C charges faster than micro USB, and battery capacity, measured in mAh, determines how long you go between charges.
Warranty coverage and product registration are worth checking before you buy, not after something breaks. Registering a device is usually what makes a warranty claim fast if you ever need one.
Buy from an authorized source. Counterfeit devices are a real problem in this category, and buying from an authorized source is the simplest way to avoid one that looks right but performs and charges unpredictably.
Frequently Asked Questions
Is a dab pen the same as a wax pen? For almost all practical purposes, yes. Both terms describe a device with a chamber that vaporizes loose concentrate directly. The terms get used inconsistently across the industry, but they're pointing at the same category of device.
Can you put wax in a 510 battery? No. A standard 510 battery only has a threaded connection for pre-filled cartridges. It doesn't have a chamber or coil built to vaporize loose concentrate.
Can you use a pre-filled cartridge on a wax pen? No, for the same reason in reverse. A wax pen's atomizer is built for loose concentrate, not for a sealed cartridge.
Which one lasts longer on a charge? It depends more on the battery's mAh rating than on the device category, but 510 batteries generally sip less power per use than wax pens, which draw more power to heat a coil for direct concentrate vaporization.
Do I need variable voltage? Not necessarily. If you've found a heat level you like, a fixed or simple preset device is fine. Variable voltage matters more if you're still figuring out your preference or you switch between different carts or concentrates often.
Which is easier for a first-time buyer? A 510 battery has a shorter learning curve, since there's no loading technique to pick up. If you're buying concentrate rather than carts, though, a wax pen with a straightforward single-temperature setting is still approachable for a first device.
If you already know which format you're buying, the next step is picking the device itself. Browse 510 thread batteries for cartridges, or wax and dab pens for concentrate.
