Prefilled and refillable pod kits differ in how they use and replace e-liquid. Prefilled pods come ready to use and are replaced once they run out. Refillable pods use bottled e-liquid, allowing the same pod to be used several times before the pod or coil needs replacing.
The difference matters when choosing between the two. A Hayati vape pod kit provides a prefilled pod format that keeps e-liquid replacement simple, while refillable kits give adult vapers more choice over flavours and bottled e-liquids. Running costs can vary between the two formats based on e-liquid prices, consumption, and pod or coil replacement. The comparison becomes clearer when you examine e-liquid handling, replacement parts, maintenance, and ongoing cost.
Prefilled Pod Kits
A prefilled pod kit is a rechargeable vape system that uses pods already filled with e-liquid. The device contains a rechargeable battery, while the pod holds the e-liquid and usually a built-in coil. When the pod becomes empty, it is removed and replaced with a compatible prefilled pod rather than being manually refilled.
Many prefilled pod kits use sealed or closed pods that come factory-filled with e-liquid. Nicotine salt is a common formulation used in prefilled vape pods, with nicotine strengths and flavours varying between products. Brands such as Hayati vape, ELFBAR, Lost Mary and IVG are associated with the wider prefilled pod market.
How Do Prefilled Pod Kits Work?
A prefilled pod kit works by combining a rechargeable device with a factory-filled pod. The device powers the coil inside the pod, while the pod supplies the e-liquid. The process requires little setup because the pod is ready to use when inserted.
- Open the pod: Remove the prefilled pod from its packaging. It already contains e-liquid.
- Insert the pod: Place it into the compatible rechargeable device.
- Vape: The battery powers the built-in coil, which heats the e-liquid and produces vapour. Depending on the model, activation may be draw-activated or controlled by a button.
- Replace the pod: Once the e-liquid is depleted, remove the empty pod and insert a new one. The rechargeable device can continue to be used and recharged when needed.
Who Are Prefilled Pod Kits Best For?
A prefilled system may suit users who want a straightforward setup with fewer steps between opening a new pod and using the device. It can also appeal to people who do not want to handle bottled e-liquid or manage separate coils.
They are particularly suited to:
- Adults seeking convenience with minimal setup.
- People who prefer not to handle e-liquid.
- Occasional users who prefer simple pod replacement.
Prefilled Pods vs Disposable Vapes
A prefilled pod kit keeps the rechargeable device while the filled pod is replaced when empty. A disposable vape, by contrast, is designed for the entire device to be discarded after use. The two formats therefore differ mainly in how the battery, e-liquid and consumable components are handled.
Pros and Cons of Prefilled Pod Kits
Prefilled pod kits offer a simple vaping setup because the pod arrives factory-filled and is ready to use. The rechargeable device is kept, while the pod is replaced when empty. This format reduces the amount of handling required, but it also limits the user’s choice of e-liquid compared with a refillable system.
Advantages
- Simple to use: The pod is ready to insert, so there is little setup involved.
- No manual filling: Users do not need to add e-liquid from a bottle.
- Easy pod replacement: An empty pod can be removed and replaced with a compatible one.
- Convenient for occasional use: The straightforward format can suit users who want minimal involvement.
- Fixed configuration: The e-liquid and coil configuration is determined by the pod manufacturer rather than selected by the user.
Disadvantages
- Limited pod choice: Users are generally restricted to pods compatible with their device or pod ecosystem.
- Less e-liquid control: Flavours and nicotine strengths depend on what the manufacturer offers.
- More pod waste: The battery is reused, but each empty pod needs to be replaced rather than refilled.
- Ongoing pod costs: Frequent users may spend more over time because replacement pods must be purchased repeatedly.
- Flavour availability can vary: Particular flavours may not always be available within a specific pod range.
Refillable Pods
A refillable pod kit is a rechargeable vape device with a removable pod or reservoir that the user fills manually with compatible e-liquid. Unlike prefilled pods, refillable systems use bottled e-liquid, giving users more choice over flavours and nicotine strengths where legally available. Refillable pod systems are also commonly referred to as open pod systems.
A refillable pod is designed to accommodate multiple fills, although the usable lifespan varies by pod design, coil type, e-liquid and usage. Some refillable pod kits use an integrated coil, so the whole pod is replaced when the coil wears out. Others have a replaceable coil, allowing the pod to be reused while only the coil is changed.
How Does a Refillable Pod Kit Work?
A refillable pod kit works through a simple cycle of filling, vaping and refilling. Unlike prefilled systems, the user adds compatible e-liquid manually and can continue using the pod until it or the coil needs replacing.
- Fill the pod: Add compatible e-liquid through the pod’s fill port.
- Wait if required: Some systems need a short wait after filling so the coil can absorb the e-liquid.
- Vape: Insert the pod into the rechargeable device and activate it by inhaling or pressing the button, depending on the model.
- Refill: When the e-liquid level becomes low, add more compatible e-liquid.
- Replace the pod or coil: When performance declines, replace the pod or coil according to the device design.
Who Are Refillable Pod Kits Best For?
A refillable system may suit users who want to select their own bottled e-liquids and have more control over compatible flavours and nicotine strengths. The format requires more involvement because filling and occasional pod or coil replacement are part of normal use.
They are particularly suited to:
- Adults seeking greater flexibility with e-liquid choice.
- People who enjoy choosing their own flavours and compatible nicotine strengths.
- Users who prefer customisation and do not mind the extra involvement of refilling and maintenance.
Pros and Cons of Refillable Pod Kits
Refillable pod kits require more user involvement because e-liquid is added manually and the pod or coil needs occasional replacement.
Advantages
- Wider e-liquid selection: Users can choose from a broad range of compatible e-liquid flavours.
- More flavour control: Different e-liquids allow users to change flavours without replacing the whole pod.
- Potentially lower running costs: Refillable systems can be more economical over time, depending on e-liquid prices, usage and pod or coil lifespan.
- More e-liquid options: Users can select compatible flavours, nicotine strengths and formulations where legally available.
- More customisation: Some devices also allow adjustments to features such as airflow, power or coil choice.
Disadvantages
- Manual filling: E-liquid needs to be added to the pod when the level becomes low.
- More maintenance: Users may need to refill, clean the pod and replace worn pods or coils.
- Potential leaks: Handling and filling the pod can create a risk of spills or leaks if the pod is overfilled or not sealed correctly.
- Pod or coil replacement: Refillable does not mean permanent. Pods or coils still need replacing over time.
- Separate e-liquid storage: Users need to purchase and store bottled e-liquid separately.
Prefilled vs Refillable Pod Kits: Key Differences
The two formats share a rechargeable device-and-pod setup, but the consumable works differently. A prefilled pod arrives with e-liquid already inside, while a refillable pod relies on bottled e-liquid added by the user. That difference affects filling, maintenance, flavour selection and running costs.
| Feature | Prefilled Pod Kits | Refillable Pod Kits |
| Setup | Minimal | More involved |
| E-liquid | Comes prefilled | Purchased separately |
| Refilling | No | Yes |
| Flavour choice | Depends on available pods | Broad compatible e-liquid choice |
| Maintenance | Generally lower | Generally higher |
| Convenience | High | Moderate |
| E-liquid choice | Limited to compatible prefilled options | Wider choice of compatible bottled e-liquids |
| Waste | Used pods are regularly discarded | E-liquid bottles and worn pods or coils are eventually discarded |
| Cost structure | Device + replacement pods | Device + e-liquid + pod/coils |
Choosing between a prefilled and refillable pod kit is less about finding a universal winner and more about comparing the factors that affect everyday use. Upfront price, running costs, convenience, maintenance and e-liquid choice can all influence long-term value.
Convenience
Prefilled pods arrive filled, so there is no need to carry an e-liquid bottle or manually fill the reservoir. Once a pod is empty, it can be replaced with a compatible one. Refillable systems involve more steps because the user needs to add e-liquid and monitor the pod or coil condition.
Flavour Choice
Refillable systems generally offer more flexibility with flavour choice. Users can select compatible bottled e-liquids instead of choosing only from the flavours available for a particular prefilled pod range. Nicotine strengths and formulations can also vary between e-liquids. However, compatibility still matters because pod and coil specifications can affect which e-liquids are suitable.
Maintenance
Prefilled systems generally require less maintenance because the pod is replaced rather than manually filled. Refillable systems can involve refilling, cleaning, checking pod condition and replacing the pod or coil when needed. Some refillable kits have integrated coils, while others use replaceable coils.
Cost
Cost depends on how each system is used. A prefilled setup involves the initial device cost followed by replacement pod purchases. A refillable setup requires the device, bottled e-liquid and occasional pod or coil replacements. Refillable systems can offer a lower ongoing cost in some cases, but actual value depends on e-liquid prices, consumption and replacement frequency.
Waste
Both systems create consumable waste. Prefilled users regularly replace used pods, while refillable users can reuse a pod for multiple fills but still discard e-liquid bottles and eventually replace pods or coils. Therefore, refillable does not automatically mean zero-waste or environmentally friendly.
Which Pod Kit Is Better for You?
There is no single winner for every adult vaper. The better option depends on what matters most to you. Prefilled pod kits focus on convenience and simplicity, while refillable pod kits offer more control, choice and flexibility.

Quick Decision Guide
A simple way to choose between the two is:
| If you want | Choose |
| The simplest option | Prefilled – Ready to use |
| More control | Refillable – Greater flexibility |
| More e-liquid variety | Refillable – Wider choice |
| Minimal handling | Prefilled – Less maintenance |
Are Refillable Pods Cheaper Than Prefilled Pods?
Refillable pods can be more economical over time, but the actual cost depends on how often the device is used and how much is spent on e-liquid, pods and coils. The main difference is how the ongoing costs are structured.
Prefilled Pod Costs
With a prefilled system, the cost usually includes:
- Device: The initial purchase.
- Replacement pods: A new prefilled pod is purchased whenever the current one is empty.
- Frequency of use: Regular users may need replacement pods more often.
Refillable Pod Costs
A refillable system usually involves:
- Device: The initial purchase.
- E-liquid: Bottled e-liquid is purchased separately.
- Pods or coils: These are replaced when they become worn.
- Usage: More frequent use means more e-liquid consumption and potentially more replacements.
A refillable system may have a lower consumable cost, but price is only one part of the comparison. A user who dislikes filling pods or replacing coils may place more value on the convenience of prefilled cartridges. Conversely, someone who uses a device frequently may care more about e-liquid cost and flavour selection.
A 30-day comparison gives a clearer picture because it accounts for actual pod consumption, e-liquid use and replacement parts rather than comparing individual products in isolation.
| Cost Comparison | How to Calculate | What Affects the Cost |
| Prefilled system | Number of pods used × price per pod | Pod price and how many pods are used each month |
| Refillable system | E-liquid consumed + pod/coil replacements | E-liquid price, monthly consumption and replacement frequency |
For first-month spending, include the initial device price. When comparing ongoing running costs, compare the consumables used over the same period instead. Price is only one part of long-term value. A refillable system may reduce consumable spending but requires filling, e-liquid storage and occasional pod or coil replacement. A prefilled system may cost more per replacement while reducing the amount of handling involved. For frequent users, e-liquid consumption and replacement frequency can have a larger effect on total cost than the initial device price.
UK Regulations and TPD Considerations
Prefilled and refillable vape products sold in the UK are subject to regulatory requirements under the Tobacco and Related Products Regulations (TRPR). For nicotine-containing products, the rules cover areas such as nicotine strength, product capacity, packaging, labelling and notification. For example, nicotine-containing e-liquid is limited to 20mg/ml, refill containers to 10ml, and e-cigarette tanks to 2ml under current TRPR requirements.
Products intended for the UK market must also meet applicable notification requirements, with nicotine-containing e-cigarettes and refill containers notified to the MHRA before sale. Packaging must meet relevant requirements, including child-resistant and tamper-evident provisions and health warnings.
A separate UK Vaping Products Duty regime takes effect on 1 October 2026. From that date, all liable vaping products released onto the UK market must have a vaping duty stamp attached. Certain unstamped products produced or imported before 1 October 2026 can remain on sale during the transitional period until 31 March 2027. From 1 April 2027, unstamped vaping products outside duty suspension cannot be sold.
FAQs
Are refillable pods better than prefilled pods?
Neither is universally better. Prefilled pods reduce filling and routine handling, while refillable pods give users more choice over compatible bottled e-liquids.
Are prefilled pods cheaper than refillable pods?
Not necessarily. Refillable systems can have lower ongoing consumable costs, but the result depends on e-liquid prices, consumption and how often pods or coils need replacing.
What is the difference between prefilled and refillable pods?
Prefilled pods are supplied with e-liquid and are normally replaced when empty. Refillable pods are filled with bottled e-liquid and can be used across multiple fills.
Which pod system is easier to use?
Prefilled pods require fewer steps. They arrive filled and can be replaced when empty, while refillable pods need manual filling.
Do refillable pods last longer?
A refillable pod is designed for multiple fills, but that does not give it a fixed lifespan. Integrated-coil pods are replaced when the pod or coil deteriorates, while replaceable-coil systems allow the pod to be retained while the coil is changed. Lifespan varies with pod design, e-liquid and usage.
Are refillable pod kits more economical?
They can be, particularly when e-liquid and replacement-part costs are lower than the equivalent prefilled-pod spend. Actual savings depend on consumption and replacement frequency.
Can you use any e-liquid in a refillable pod?
No. Compatibility depends on the device, pod and coil design, as well as the e-liquid formulation. Factors such as coil resistance and PG/VG ratio can affect how suitable a liquid is for a particular pod. Follow the manufacturer’s recommendations rather than assuming every bottled e-liquid will work with every refillable system.
How often should pod cartridges be replaced?
Replace a pod when flavour deteriorates, vapour production falls noticeably, a burnt taste develops, or the pod starts leaking or showing signs of damage.
Final Thoughts
Prefilled and refillable pod kits solve the same basic need in different ways. A prefilled system reduces filling and routine handling, while a refillable system gives users more control over the e-liquid they use and how often they replace consumables.
Cost can favour a refillable setup for some users, but convenience also has value. Cost depends on actual usage: how much e-liquid is consumed, how often pods or coils are replaced, and how much value the user places on ready-filled convenience.
A prefilled system may make more sense when reducing filling and routine handling is the priority. A refillable system may be a better fit when e-liquid choice and control over consumables matter more.
