A refillable vape pen is a rechargeable battery paired with a tank, pod or cartridge that the filler loads with licensed oil, and for a UK brand the choice is a closed pod system or a modular 510 set. Pods give a matched, tidy kit where the pod and battery are designed as a pair.
A 510 set gives you free choice of cartridge and battery from different ranges. Neither is better in every case, because the right answer depends on your oil, your filling line, your packaging and how many SKUs you want to hold.
The sections below compare both routes using specifications taken from the live product pages.
Key takeaways
- Pod systems are closed: each pod fits only its own battery family, so the pairing decision is made for you.
- 510 sets are modular: any standard 510 cartridge fits a standard 510 battery, which widens choice but adds fit checks.
- Pods suit brands that want a complete branded kit; 510 suits brands that want to vary tank size, core and battery.
- Filling differs: pods are small and quick to fill, while glass 510 cartridges offer open top-fill and larger inlets for thick oil.
- Our hardware is sold empty for licensed filling, and the product pages state it is for CBD use.
Pods vs 510 in one answer
Choose a pod system when you want a closed, matched kit, and choose a 510 cartridge and battery set when you want modular choice. That single difference drives most of the others in the comparison below.
A pod battery accepts only the pods made for it, so a customer cannot mix in the wrong hardware. A 510 battery accepts any cartridge with the right thread, so the same battery can serve several cartridge lines.
In practice, many UK brands start with one format and add the other once the first range sells. Neither route requires you to give up the other later, because the hardware sits on separate product pages and is ordered independently.
What a refillable vape pen is
A refillable vape pen is a reusable device in which the container holding the oil is filled by the producer, or replaced by the user, while the battery recharges over a USB port. The term covers two formats that look different but follow the same logic.
- Pod pens: a small magnetic pod clicks onto a battery body.
- 510 pens: a threaded cartridge screws or drops onto a battery with a standard 510 connection.
In both, the heating element sits in the pod or cartridge, not in the battery. That is why the ceramic core, the inlet size and the resistance are listed on the consumable, while capacity, voltage and charging are listed on the battery.
The wording matters for compliance too. Refillable and rechargeable hardware is the reusable category that remains on sale after the UK single-use vape ban, as our note on empty disposable pen hardware explains.
How pod systems work
A pod system pairs a pod with a battery through a magnetic connection, and the pod is the part you fill. The battery is usually inhale activated, so the user draws and the device fires.
The CCELL Eazie Pod Evomax is a refillable pod with an EVOMAX ceramic core and a stainless steel centre post, offered in 0.5ml, 1.0ml and 2ml. It needs a dedicated Eazie battery, and the product page is clear that it does not fit standard 510 batteries.
The CCELL Luster Pro is a 350mAh pod battery with constant power output and three wattage settings of 6.5W, 7.5W and 8.5W. It takes 0.5ml and 1ml Luster Pods and Luster Pro Pods through a drop-in magnetic connection, in a full metal 91 x 21 x 11mm body.
The CCELL Dart-X is the second-generation Dart battery. It runs 480mAh with three temperature settings, a child-resistant lock and a motion-triggered LED, and it takes both Dart-X and first-generation Dart pods in 0.5ml and 1.0ml.
| Platform | Battery | Pod sizes |
|---|---|---|
| Eazie | 265mAh matched unit, or the Eazie Pro with display | 0.5ml, 1.0ml, 2ml |
| Luster Pro | 350mAh, three wattage steps | 0.5ml, 1ml |
| Dart-X | 480mAh, three temperature settings | 0.5ml, 1.0ml |
The three platforms do not cross over. Our Eazie pod system guide and the Luster Pro versus Dart-X comparison explain which pods belong to which battery. The wider pod system category lists every platform.
How 510 cartridge and battery sets work
A 510 set uses a cartridge with a standard 510 thread on a battery with a matching connector, so the two parts come from separate listings. Our guide on what a 510 thread cartridge is covers the thread itself.
The CCELL TH2 EVOMAX is a borosilicate glass cartridge with EVOMAX heating, an open top-fill layout and a 4 x 2mm aperture on a universal 510 thread. Tank options are 0.5ml and 1.0ml, with snap-fit mouthpieces in Black or White.
The CCELL Palm Pro is a 500mAh palm-fitting 510 battery with 2.8V, 3.2V and 3.6V settings, a 10-second preheat, an adjustable airflow collar and a drop-in magnetic connection. The listing explains that a magnetic cartridge nut is fitted to the cartridge to use the magnet.
Battery features are where 510 sets pull ahead on control. The Palm Pro lets the user pick 2.8V, 3.2V or 3.6V and open or narrow the airflow, so one battery can be tuned to the oil in the cartridge.
The cartridge carries the heating element, so the same Palm Pro can run different cartridges. Fit still needs checking: wider tanks can overhang a slim battery body, and the battery pages list diameters. Our magnetic and display 510 battery guide compares the Palm Pro with the Kap, Stylo and others.
Pod system and 510 set compared
The table sets the two formats side by side on the factors that matter when a new line is specified. It describes the general pattern, and individual products differ.
| Factor | Pod system | 510 set |
|---|---|---|
| Filling | Small pod, quick to fill | Open top-fill glass or other tank, wider range of sizes |
| Battery choice | One battery family per pod | Any standard 510 battery |
| Branding | Engraving or customisation on battery and pod parts | Engraving on the battery, plus cartridge colour and mouthpiece choices |
| Range flexibility | Fixed pod sizes per platform | Mix cartridge cores, sizes and batteries |
| Fit risk | Low, pairs are matched | Higher, diameter and thread need checking |
| Customer experience | Plug-in kit, few decisions | Familiar threaded format |
No row is a winner on its own. A pod platform narrows your choices to reduce fit mistakes, whereas a 510 set keeps your options open and asks more of your specification work.
Filling and sealing
Pods and 510 cartridges are both filled empty and sealed by the producer, but the steps differ in scale and in how the oil reaches the heating element. Our guide to choosing hardware by oil type explains how viscosity changes what a tank or pod needs.
Filling a pod
The Eazie product page advises filling with licensed oil while leaving a small air gap. It also suggests letting the oil settle into the ceramic before first use and not overfilling, which helps avoid leaks into the magnetic contacts.
Pods are compact, so each unit takes a small volume and a line fills many of them. Wipe the magnetic contacts clean before packing, because oil on the contacts can stop a pod from firing.
Filling a 510 cartridge
An open top-fill cartridge such as the TH2 EVOMAX is loaded through the top before the mouthpiece is fitted, and its wide aperture is listed as suiting viscous oils better than a narrow port. Snap-fit mouthpieces press on in place of a screw step, which can speed capping on a line.
Match the inlet to your oil and test a small batch before committing to volume. Resistance and capacity figures also vary between listings, so confirm them on your purchase order.
Branding and packaging
Branding differs because a pod kit is usually sold as a complete unit, while a 510 set is often sold as parts. That changes what you print, engrave and box.
- Laser engraving: available through us on batteries, pods and selected hardware, and it is UK only. The Luster Pro, Dart-X and Palm Pro listings state customisation is available.
- Colour: Eazie pods offer Black, Blue, Green or Purple mouthpieces, and the Palm Pro lists five finishes including Champagne and Ruby.
- Kit versus components: a pod battery plus pods suits a boxed kit. A 510 cartridge in its own tray suits a refill-style retail line.
- Child resistance: the Dart-X has a child-resistant lock, the Luster Pro has a child-resistant button, and the Eazie Pro has a 5-click child lock. CCELL describes these as child-resistant, and we do not claim formal certification.
Think about the carton as well as the device. A kit needs space for a battery, a pod and a charging lead, whereas a cartridge pack needs a tray that protects the mouthpiece.
Range planning for a new brand
For a new brand, start with the format that matches how you will fill and sell, then add the second format only when the first has a clear customer base. Treat the following as a planning approach rather than a forecast.
- Decide your hero oil. Thick oils and mixed ranges point towards EVOMAX hardware in either format.
- Choose one battery path. One pod platform or one 510 battery keeps training simple.
- Run a small pilot. Fill a few units, check behaviour, then order volume.
- Add variety later. New sizes or colours come after the base SKUs are stable.
The next table links common briefs to a sensible starting format. It is built on the product specifications.
| Brief | Start with | Reason |
|---|---|---|
| Boxed starter kit with few decisions | Pod system | Pod and battery are matched, so the customer cannot buy the wrong pairing |
| Several oils and fill sizes | 510 set | Cartridge size and core change without changing the battery |
| Thick or mixed oils | EVOMAX in either format | CCELL positions EVOMAX for all oil types |
| Feature-led battery with preheat | Palm Pro or Eazie Pro | Both list preheat; the Palm Pro adds airflow and three voltages |
If you want a single-piece device as part of the line, our 1ml all-in-one hardware guide covers that class, which suits a different brief from pods and 510 sets. For ranges that mix formats, browse the cartridge category alongside the pod pages and ask our team to build one quote.
Common mistakes
Most refillable hardware problems come from fit and pairing rather than from the parts themselves. These are the mistakes our team sees on new ranges.
- Mixing systems: Luster, Dart and Eazie pods are not interchangeable, and none of them fit 510 batteries.
- Ignoring battery pairing: a pod ordered without the matching battery leaves the customer with something that cannot fire.
- Overfilling: oil on the magnetic contacts or the 510 pin can stop a pod or cartridge from working.
- Skipping the diameter check: wider cartridges can overhang slim 510 batteries, so check listed diameters.
- Quoting voltages the page does not give: the Eazie Pro and Dart-X listings do not give per-mode voltages or wattages, so do not invent them in your instructions.
To avoid these, specify the pod, the battery and the colour on one order, and write the pairing into your product sheet. Trade quotes and availability come through the product pages and our contact route.
FAQ
What is a refillable vape pen?
A refillable vape pen is a reusable device with a rechargeable battery and a pod, tank or cartridge that is filled with licensed oil. It comes in two main formats: magnetic pod systems and 510 thread cartridge and battery sets. The heating element sits in the pod or cartridge, not in the battery.
Are pods or 510 cartridges better for a brand?
Neither wins on every factor. Pods give a matched, closed kit that reduces fit mistakes, while 510 sets give modular choice of cartridge core, size and battery. Pick pods for a boxed kit with few decisions, and 510 for flexibility across oils and fills, then pilot a small batch.
Can I use any pod with any battery?
No. Eazie pods need Eazie batteries, Luster pods need the Luster Pro, and Dart-X takes Dart-X and first-generation Dart pods. The product pages state these are different magnetic formats and none fit standard 510 batteries, so order the pod and its matching battery together.
Can pods be refilled more than once?
The Eazie Pod Evomax is listed as a refillable pod, but the page gives no refill count and we do not quote one. How often a pod can be reused depends on the oil, handling and wear, so test it with your own oil and follow your own quality checks.
Which refillable hardware suits thick oil?
CCELL positions EVOMAX for all oil types, and both the Eazie Pod Evomax and the TH2 EVOMAX use it. The TH2 EVOMAX also has open top-fill and a 4 x 2mm aperture. Those are CCELL claims, so test your thick oil in a small batch first.
Do refillable pens need a special battery?
Pods need the specific battery for their platform, such as Eazie, Luster Pro or Dart-X. 510 cartridges need a standard 510 battery, and the Palm Pro is one example. Check thread, connection and body diameter on the product page before ordering, because the heating element sits in the pod or cartridge.
