JNR P4 Comparison to Popular Prefilled Devices

The vaping landscape in the UK has shifted in the last few months from simple, disposable closed systems (like Vuse and RELX) toward hybrid systems that bridge the gap between convenience and long-term value. Traditional prefilled devices offer unmatched simplicity for new vapers, but their recurring costs and environmental impact become friction points for dedicated users.

The emergence of the JNR P4 Stellarc pod kit encourages vapers to reconsider and take a closer look at the latest in convenient vaping. In this article I’ll be providing a deep analysis of how the JNR P4 Stellarc stacks up against established favourites, guiding both new, and heavy vapers toward the most cost-effective and enduring choice available.

Are Hybrid Vape Systems Better Than Traditional Prefilled Pods?

Whether a hybrid system is "better" depends on your priority, but the hybrid design undeniably solves the primary issues of traditional prefilled vapes: longevity and cost.

Hybrid vapes combine the simplicity and convenience of disposable devices with the long-lasting performance of traditional prefilled pod kits. This creates an accessible, user-friendly vape that’s suitable for all experience levels.

Traditional prefilled pods (typically 2ml, TPD compliant) offer the pinnacle of fuss-free use: discard when empty, insert new pod. This zero-maintenance approach is ideal for beginners.

Hybrid systems, in contrast, introduce reusability. They use a standard 2ml pod paired with a significantly larger, rechargeable e-liquid reservoir that is refilled using standard bottles. This design retains the simple, sealed nature of the pod while drastically extending the e-liquid supply. The result is a device that delivers the same draw-activated, mouth-to-lung (MTL) style users love, but with cost-savings that far surpass older models.

The JNR P4 appeals directly to the heavy vaper who wants the simplicity of a closed system but is weary of high weekly costs and constant pod disposal. It offers monumental longevity, providing both upfront convenience and substantial long-term savings.

The JNR P4 Comparison: Redefining Vaping Endurance

The JNR P4 Stellarc has garnered rapid attention for its unprecedented capacity and sophisticated design, representing a significant step forward in the 'closed-refillable' category. It is specifically engineered for users who value extreme endurance without sacrificing the smooth, satisfying experience associated with nicotine salts.

This innovative system comes standard with a full kit, which includes the device, two 2ml prefilled pods, two 10ml automatic refill containers, and four 10ml bottles of e-liquid. This configuration adheres to UK regulations while providing a total potential capacity of 64ml of vape juice straight out of the box. This massive e-liquid reserve is the key to its longevity, promising weeks of uninterrupted use.

While the ambitious 100,000 puff claim refers to the total system capacity, rather than the actual amount of puffs delivered (which can be closer to 30,000) - even conservative real-world estimates show the Stellarc dramatically reduces the frequency of coil and pod replacements compared to standard 600-puff disposables or 2ml closed pod packs, making it incredibly cost-effective.

Design, Capacity, and Innovation

The physical design of the Stellarc blends the box-mod profile with the sleek aesthetics of modern pod kits, ensuring comfort and easy portability. Crucially, the device features an intuitive LED screen that displays the remaining battery life as a percentage, eliminating the guesswork associated with older-generation devices.

Its innovative dual e-liquid system allows the device to function as a closed-refillable unit: the user loads the 10ml external refill containers, which then seamlessly feed the primary 2ml pod. This mechanism is clean, TPD compliant (100% UK legal), and allows for the instant switching between two different loaded flavours—a major advantage for vapers who enjoy variety.

Central to its longevity is the high-capacity 1200mAh battery. This is considerably larger than the 350mAh to 850mAh batteries found in most popular prefilled closed systems. The greater battery capacity ensures reliable power for days or weeks before requiring a recharge via the convenient USB-C port, complementing the enormous e-liquid capacity.

The Technology Under the Bonnet

The JNR P4 Stellarc uses advanced 1.2Ω dual mesh coil technology. Mesh coils are superior because they heat e-liquid evenly across a larger surface area, resulting in far richer, more consistent flavour production and dense, satisfying vapour clouds.

Flavour consistency is vital for high-capacity systems. The dual mesh coil is engineered for endurance, maintaining the intense flavour delivery of the nicotine salt e-liquid throughout the pod’s extended lifespan.

The entire system is optimised for a mouth-to-lung (MTL) style of vaping, closely mimicking the draw resistance of a traditional cigarette. This makes the transition from conventional prefilled pods seamless and enjoyable for former smokers.

The Established Giants: Vuse and RELX Alternatives

Vuse and RELX have defined the market for simplicity and accessibility in the UK. Their closed systems require virtually no user knowledge of wattage or e-liquid management, built around the concept of maximum convenience. Users buy a battery unit and then purchase packs of prefilled, sealed 20mg (2%) nicotine salt pods.

• Vuse and its Ecosystem: Known for minimalism and wide availability (e.g., Vuse Pro), Vuse offers a snappy, reliable MTL experience. However, the typical 2ml pod is discarded once empty, which quickly adds up financially for heavy users that might get through multiple pods daily. The Vuse system is a classic prefilled pod kit with no ability to refill, limiting flavour choice to the manufacturer's range.
• RELX and its Performance: RELX (e.g., Infinity) focuses on 'Super Smooth' performance and sleek aesthetics. Their 2ml pods are highly leak-resistant. The constraint remains the same: high ongoing cost per millilitre of e-liquid and the environmental impact of constantly disposing of small, complex components.

Detailed Comparison: JNR P4 vs. Popular Prefilled Systems

The comparison shifts from simple features to focus on long-term economics. The major difference is the definition of 'prefilled': Vuse and RELX pods are prefilled and disposable, whereas the JNR P4 system is prefilled with a massive, continuous supply of e-liquid designed to last.

Cost Analysis and Long-Term Value

The JNR P4 kit has a higher upfront cost than a Vuse or RELX starter kit, but this is immediately offset by the high volume of e-liquid included. Traditional prefilled pod packs cost between £6 and £8 for two 2ml pods (4ml total), resulting in a very high cost per millilitre.

The JNR P4 system slashes running costs dramatically. Once the initial kit is purchased, the user only replaces low-cost standard 10ml e-liquid bottles. This shifts the financial model from a consumable-based cost to a fixed investment, resulting in savings that can reach up to 90% compared to heavy reliance on traditional prefilled packs. This high-capacity system translates a minor inconvenience of occasional refilling into hundreds of pounds saved over a year!

Flavour Freedom and E-Liquid Choice

Vuse and RELX systems can be quite restrictive, as users are limited to the flavours and nicotine strengths available from the manufacturer. The JNR P4 kit overcomes this by using standard bottled e-liquid. Users can select any 50/50 ratio 10ml bottle*, opening up an infinite spectrum of flavour choices, from bar salt e-liquids that replicate disposables to complex dessert mixes. This freedom from proprietary pods is a huge win for consumer control and customisation.

• However, it may be best to stick to flavours similar to those within the JNR P4 prefilled pods. As they utilise fixed mesh coils,  mixing drastically different flavours could result in unexpected, or unpleasant, flavour combinations.

The Environmental and Convenience Angle

While simplicity drives users toward prefilled systems, the environmental impact is important to consider. Every finished Vuse or RELX pod means disposing of a small piece of plastic, metal, and residual e-liquid.

Waste Reduction and Sustainability

The hybrid approach of the JNR P4 Stellarc drastically cuts down on e-waste. The main device is rechargeable and designed for extended, multi-month use. Users primarily dispose of recyclable 10ml e-liquid bottles and the larger pod unit only after consuming many millilitres of e-liquid (far less often than a 600-puff pod). This makes the JNR P4 a far more sustainable choice for the environmentally conscious vaper.

User Experience and Transition

Current users of simpler systems will find the transition surprisingly easy, as the Stellarc maintains the core usability principles that made Vuse and RELX popular.

• For the Vuse and RELX User: The draw-activation is instantaneous, and the MTL airflow is tightly controlled, delivering the same satisfying, cigarette-like draw. The coil technology is optimised for 20mg nicotine salt e-liquid, ensuring the throat hit and nicotine delivery are virtually identical to what users are accustomed to. The large display is an undeniable quality-of-life upgrade, eliminating the frustration of having your battery die unexpectedly.
• The Refilling Process Explained: The Stellarc's design mitigates mess: a dedicated 10ml refill container clips into the device and automatically feeds the 2ml pod. To refill the main supply, the user simply unclips the 10ml container, fills it from their chosen e-liquid bottle, and re-clips it. This process is clean, secure, and avoids the messy, fiddly process of dropping liquid directly into a small pod opening.
• The Grey Haze Ecosystem: As a leading provider of advanced vaping solutions, Grey Haze focuses on products that offer their customers genuine long-term value and satisfaction. The JNR P4 Stellarc aligns with this, offering a premium experience backed by exceptional engineering—a gateway to massive e-liquid variety and a more sustainable habit.

Frequently Asked Questions (FAQs)

What is the actual lifespan of the JNR P4 Stellarc coil, and how do I know when to replace the pod?

The dual mesh coil is engineered for extreme longevity, handling multiple refills. While the "100,000 puff" number refers to the total system capacity, a single coil lasts significantly longer than a standard disposable pod coil. Replace the pod when the flavour consistency drops noticeably, or if you taste a burnt/muted flavour, which usually occurs after several weeks of heavy use.

Is the JNR P4 Stellarc device TPD compliant for sale and use in the UK?

Yes, it is fully TPD compliant. Compliance is achieved because the primary consumption unit is the 2ml pod. The additional e-liquid is contained in separate, regulated 10ml bottles which are then used to refill the internal reservoir, ensuring the product is entirely legal and safe.

How does the battery life of the Stellarc compare to my current Vuse or RELX device?

The JNR P4 Stellarc's 1200mAh battery is significantly larger than the 350mAh to 850mAh batteries in most popular prefilled systems. This greater capacity means the Stellarc can last for days on a single charge, even with heavy usage, before needing a top-up via its fast USB-C port.

Can I use any brand of e-liquid to refill the JNR P4 Stellarc system?

Yes. Once the initial supply is finished, you can use virtually any brand of 10ml bottled e-liquid with a 50VG/50PG ratio. This viscosity is perfectly suited for the 1.2Ω mesh coils and the MTL style, allowing you to choose your flavour and nicotine concentration freely.

Is the JNR P4 Stellarc more difficult to maintain than a disposable vape alternative?

The Stellarc is only marginally more involved. While disposables require zero maintenance, the Stellarc requires two simple steps: recharging the battery and refilling the 10ml external container when empty. Since the coil is integrated into the pod, there are no messy coil changes, and the vast savings easily justify the minimal added effort.

Conclusion

In conclusion, moving from familiar territory like Vuse or RELX to a high-performance hybrid like the JNR P4 Stellarc is the logical next step for any committed vaper seeking long-term value. This advanced device effectively addresses the high running cost and accumulated waste of traditional systems while maintaining the simple, satisfying MTL experience. By delivering massive e-liquid capacity, superior mesh coil technology, and flavour freedom, the JNR P4 firmly positions itself as a genuine next-generation upgrade.
