The vaping world is constantly evolving, steadily moving towards more sustainable, cost-effective, and flexible alternatives to smoking. If you are seeking the incredible longevity of a disposable but with the freedom to choose your own flavours, you have likely encountered the JNR P4 Stellarc 100K. This revolutionary device is a true game-changer, blurring the lines between a high-capacity big puff vapes and a fully-fledged refillable pod system. It boasts astonishing potential, with its impressive puff count, a massive 1200mAh battery, and a futuristic animated screen.

However, a device this advanced requires a little more care than its single-use cousins. To get the absolute best performance and reach that high-puff milestone, understanding its unique refill mechanism and proper maintenance is essential. This guide is your definitive resource for everything related to JNR P4 Stellarc pod kit maintenance, from your very first refill to troubleshooting common issues. We will walk you through every step to ensure your device delivers a flawless, flavourful experience every single time.

Why is My JNR P4 Stellarc Pod Kit Leaking?

Let's address one of the most common frustrations for any vaper right from the start. You have just filled your new kit, and you notice e-liquid seeping from the pod. A leak can be messy and wasteful, but the good news is that it is almost always preventable. The JNR P4's unique auto-feed system is robust, but understanding the pressures involved is key to keeping it sealed and secure.

The most common culprit is improper filling of the 10ml e-liquid container. This reservoir is designed to hold your e-liquid and feed it into the 2ml pod. If you fill this container to the absolute brim, leaving no air bubble at the top, you create positive pressure. When you seal the silicone bung, this pressure has nowhere to go and can force e-liquid out through the coil's wick or any available seal. Always leave a small air pocket at the top when you refill.

Another frequent cause is related to how you inhale. The JNR P4 is an inhale-activated device, and its 1.2-ohm coil is designed for a Mouth-to-Lung (MTL) draw, which is a gentle, cigar-like puff. If you are new to vaping and used to cigarettes, you might be inhaling very sharply and forcefully. This aggressive draw can quickly pull too much e-liquid into the coil - faster than it can be vapourised. This floods the coil, leading to gurgling and, eventually, leaking. Try a slower, gentler, and longer inhalation.

Of course, physical damage can also be to blame. Take a moment to inspect both the 2ml pod and the 10ml container. Look for any hairline cracks in the plastic, which can occur if the device is dropped. Also, check the small silicone seals and bungs. If one is torn or is not sitting flush, it will break the vacuum and allow e-liquid to escape. This is a common issue across all vape pods.

Finally, consider the e-liquid you are using. The JNR P4's 1.2-ohm coils are designed for thinner e-liquids. The ideal choice is a 50/50 VG/PG blend, which is standard for nicotine salts and many 10ml freebase e-liquids. If you try to use a very thick, high-VG e-liquid (like a 70/30 or 80/20 shortfill), it will struggle to wick properly, leading to dry hits. Conversely, an e-liquid that is extremely thin (high PG) could be more prone to finding small gaps, especially when combined with forceful inhales. Sticking to a 50/50 ratio is your best bet for a leak-free experience.

A Complete Guide to Refilling the JNR P4 Stellarc

The refilling process for the JNR P4 is its most unique feature, so let's break it down into simple, easy-to-follow steps. Mastering this is the key to enjoying the device's incredible economy and flavour-switching capabilities.

Understanding the Unique Auto-Feed System

First, it is vital to understand the components you are working with. You have the main device (the battery), which houses the 1200mAh battery and the smart screen. Then you have two key parts: the 2ml magnetic pod and the 10ml refillable container. The 2ml pod is the part that contains the actual coil and wick, and it clicks into the top of the device. The 10ml container is a larger reservoir that you fill with your e-liquid. This container slides into the main body of the device and, through a clever auto-feed system, it automatically keeps the 2ml pod topped up with e-liquid. This means you only need to refill the large 10ml container, not the small 2ml pod, making the process much cleaner and less frequent.

Step-by-Step Refill Instructions

Here is how to refill your JNR P4 Stellarc correctly every time to prevent leaks and ensure perfect performance.

1. Remove the 10ml Container: First, remove the magnetic 2ml pod from the top of the device and set it aside. Then, slide or pull the 10ml e-liquid container out from the main body of the device.
2. Locate the Fill Port: On the 10ml container, you will find a small silicone bung or plug. This covers the fill port.
3. Open the Port Carefully: Gently lift this silicone bung to reveal the opening. Be careful not to tear it, as a secure seal is crucial for preventing leaks.
4. Fill with Your E-Liquid: Take your chosen e-liquid bottle, which should ideally be a 10ml bottle with a standard nozzle. Insert the nozzle into the fill port.
5. Fill Slowly and Leave an Air Bubble: Squeeze your e-liquid bottle gently, filling the 10ml container. This is the most important step: do not fill it 100% to the top. Stop when it is about 90-95% full. Leaving a small air bubble at the top is essential to prevent pressure build-up.
6. Seal the Port Securely: Press the silicone bung firmly back into place. Double-check that all edges are flush and that it has created a tight seal.
7. Wipe and Re-assemble: Use a paper towel or tissue to wipe any stray e-liquid droplets from the outside of the container. Once it is clean and dry, slide the 10ml container back into the JNR P4 device until it sits securely.
8. Re-insert the 2ml Pod: Finally, click the 2ml magnetic pod back into the top of the device. The auto-feed system will now begin to top up the 2ml pod from the reservoir you just filled.

Priming Your Pod (The First Fill is Critical)

If you are using a brand new, out-of-the-box 2ml pod, you must perform a crucial one-time step called "priming". The 1.2-ohm dual mesh coil inside the pod is surrounded by dry, organic cotton. If you try to vape before this cotton is fully saturated with e-liquid, the coil will heat the dry cotton, resulting in a horrible burnt taste known as a "dry hit". This will permanently ruin the coil, and you will need to use a new pod.

To prime your pod correctly, simply follow the refill instructions above. Once you have re-inserted the 10ml container and clicked in the new 2ml pod, just wait. The auto-feed system will fill the 2ml pod. You can often see the e-liquid level rising. Once it appears full, let the entire device sit undisturbed for at least five to ten minutes. This allows the cotton wick to soak up the e-liquid fully. After 10 minutes, you are safe to take your first puff.

Choosing the Right E-Liquid for Your 1.2-ohm Coil

We touched on this in the leaking section, but it is worth expanding on, as it is vital for both maintenance and flavour. The 1.2-ohm coil in your JNR P4 pods is a Mouth-to-Lung (MTL) coil. These coils have a tighter draw and operate at a lower power, mimicking the sensation of smoking. They are not designed for the large "sub-ohm" clouds you might see from larger devices.

For these coils, the e-liquid composition is key. You should always opt for e-liquids with a 50/50 VG/PG ratio. Propylene Glycol (PG) is a thin liquid that carries flavour very well and provides the "throat hit". Vegetable Glycerin (VG) is a much thicker liquid that produces denser vapour. A 50/50 blend provides the perfect balance: excellent flavour, a satisfying throat hit, and a discreet amount of vapour, all while being the perfect consistency for the coil to wick efficiently.

This 50/50 ratio is the standard for most nicotine salt e-liquids, which are an excellent choice for the JNR P4. Nic salts provide a smoother inhale at higher nicotine strengths and are absorbed by the body more quickly, satisfying cravings faster. You can also use traditional "freebase" nicotine e-liquids, as long as they are in a 50/50 VG/PG blend. Using thick, high-VG e-liquids (e.g., 70/30) will not work. The liquid will be too thick for the cotton to absorb, leading to constant dry hits and a burnt-out coil.

How to Properly Maintain Your JNR P4 Stellarc 100K

Proper maintenance of your JNR P4 Stellarc 100K is the secret to achieving that incredible 100,000 puff count and ensuring every puff is as fresh and flavourful as the first. It is not just about refilling; it is about regular cleaning and understanding the lifespan of your components. This device is an investment in a better vaping experience, and a few minutes of care each week will pay dividends.

The Daily, Weekly, and Monthly Cleaning Routine

Knowing how to clean vape pods and devices is a fundamental skill. We can break it down into a simple, manageable schedule.

Daily Check (30 Seconds): Each day, or every time you pick up your device, give the mouthpiece (drip tip) a quick wipe with a clean tissue. This is basic hygiene. Before you take a puff, it is also good practice to quickly remove the magnetic 2ml pod and glance into the chamber it sits in. It is perfectly normal for a small amount of condensation to build up here. Use a cotton bud (Q-tip) to quickly wipe this moisture away. This prevents it from building up and potentially interfering with the contacts.

Weekly Deep Clean (5 Minutes): Once a week, set aside five minutes for a more thorough clean. This will keep your device in pristine condition.

1. Remove both the 2ml magnetic pod and the 10ml e-liquid container.
2. Take a dry cotton bud and gently clean the metal contacts on the very bottom of the 2ml pod. E-liquid residue or condensation can form here, leading to a poor connection.
3. Take another dry cotton bud and clean the corresponding spring-loaded metal contacts inside the device (in the chamber where the 2ml pod sits). Be gentle.
4. If you see any stubborn grime on the contacts, you can very lightly dampen a cotton bud with a small amount of isopropyl alcohol (rubbing alcohol) and carefully scrub the contacts. Ensure you let it evaporate completely (it only takes a few seconds) before re-inserting the pod. Never use water on these electrical components.
5. Thoroughly clean the entire pod chamber and the channel for the 10ml container with a dry cloth or paper towel, removing all dust, lint, and e-liquid residue.
6. Wipe down the exterior of the device, including the animated screen, with a soft microfibre cloth.
7. Monthly Check (1 Minute): Once a month, inspect the USB-C charging port at the bottom of the device. Because this device lives in pockets and bags, the port can easily collect lint, dust, and debris. This build-up can prevent the charging cable from making a proper connection. To clean it, use a non-metallic tool. Never stick a metal paperclip or pin inside, as you could short-circuit the device. Gently remove any visible debris.

When to Replace Your 2ml Pod

The "pod" in a pod system like this refers to the 2ml section that contains the coil. In the JNR P4, the 1.2-ohm dual mesh coil is built directly into this pod. This means you do not replace the coil; you replace the entire 2ml pod. The coil is the heating element that vapourises the e-liquid, and like any heating element, it has a finite lifespan. The 100,000-puff claim refers to the device's battery and refill capacity overall, not the life of a single coil, or the amount of e-liquid provided.

You will know it is time to replace your 2ml pod when you notice one of these three clear signs:

1. A Burnt or "Off" Taste: This is the most common and obvious sign. Even with a full 10ml container, your vape tastes burnt, metallic, or just plain bad. This means the cotton wick has degraded or burnt, and it is time for a new pod.
2. Significantly Reduced Vapour Production: If you are taking a puff and getting very little vapour, and you know the device is charged, it is a sign the coil is "gunked up". Residue from e-liquid (especially sweet flavours) caramelises on the coil over time, insulating it and preventing it from vapourising liquid efficiently.
3. Constant Gurgling or Leaking: An old coil's wicking material can become over-saturated and degraded. It loses its ability to hold the e-liquid correctly, leading to constant flooding and leaking, even if you are doing everything else right.

The lifespan of your pod depends almost entirely on your usage habits and e-liquid choice. If you exclusively use very sweet e-liquids, the sucralose and other sweeteners will caramelise and kill your coils much faster, perhaps in as little as a week. If you "chain vape" (take many puffs back-to-back without a break), you risk drying out the wick and burning it prematurely. With a high-quality 50/50 e-liquid and a normal vaping pace, you can expect a single 2ml pod to last anywhere from one to three weeks.

Troubleshooting Common JNR P4 Stellarc Issues

Even with perfect maintenance, you might occasionally run into a small issue. Here is a quick guide to solving the most common problems.

Issue: My Vape is Gurgling or "Spitting Back" A gurgling sound means the coil is flooded with e-liquid. This often happens right after refilling or if you have inhaled too hard. This excess liquid can get super-heated and "spit" hot droplets up the mouthpiece.

• The Fix: Remove the 2ml magnetic pod from the device. Wrap it in a piece of tissue or paper towel. With the mouthpiece facing down, give it a few sharp flicks (like you are shaking down an old-fashioned thermometer). This will force the excess e-liquid out of the central chimney and into the tissue. Wipe the pod clean and re-insert it. The gurgling should be gone.

Issue: I am Getting a Burnt Taste (Dry Hit) This is the worst sensation for a vaper. It means the coil is heating dry cotton.

The Cause:

1. Empty Reservoir: Your 10ml container is empty and can no longer feed the 2ml pod. Check your e-liquid level on the animated screen and refill if necessary.
2. Dead Coil: The pod is at the end of its life. The taste will not go away. See the section above and replace the 2ml pod.
3. Chain Vaping: You are vaping too quickly. The wick does not have time to re-saturate between puffs. The fix is simple: slow down. Wait 20-30 seconds between inhalations.
4. Wrong E-Liquid: You are using high-VG e-liquid, which is too thick to wick properly. Switch to a 50/50 blend immediately.

Issue: My Device Is Not Firing (No Vapour) You take a puff, and nothing happens. The inhale-activation is not working.

The Cause:

1. Dead Battery: The 1200mAh battery is depleted. Check the animated screen and charge the device using the supplied USB-C cable.
2. Dirty Contacts: This is very common. As described in the cleaning section, condensation or residue has built up on the metal contacts on the bottom of the 2ml pod or inside the device. Remove the pod, clean both sets of contacts thoroughly with a dry cotton bud, and try again.
3. Faulty Pod: The pod itself may be a dud. This is rare, but it can happen. Try a completely new 2ml pod. This is why having a spare is always a good idea when you are exploring new Vape Kits.
4. Device Issue: If you have charged the device, cleaned the contacts, and tried a new pod, it may be a rare issue with the device itself. This device is more complex than simple Prefilled Pod Kits, so hardware faults, while uncommon, can occasionally arise.

Battery Safety and Safe Disposal

A crucial part of maintenance is battery care and responsible disposal. This ensures your safety and protects the environment.

Smart Charging Practices

The JNR P4 has a large 1200mAh battery, but how you charge it matters.

• Use the Right Plug: Always use the USB-C cable that came with your device. Plug it into a low-power source, such as a laptop's USB port, a games console, or a 1-amp (1A) wall plug.

• Avoid Fast Chargers: Do not use a high-powered "fast charger" from your smartphone or tablet. These plugs can output 2A, 3A, or more, which can overwhelm the battery's management chip. This will degrade the battery's overall health and lifespan, and in extreme cases, can be a safety risk.

• Do Not Charge Overnight: This is the golden rule of vape safety. Once the animated screen shows 100%, unplug the device. Leaving it on charge for hours on end puts unnecessary strain on the battery.

• Mind the Temperature: Never charge your device in extreme temperatures. Avoid leaving it to charge in a hot car or a freezing cold room.

How to Dispose of Your Old Pods and Device

When your components reach the end of their life, you cannot just throw them in the bin.

• Old 2ml Pods: The empty 2ml pods are made of plastic and metal (the coil). Unfortunately, these are too small and complex to be recycled. They should be placed in your general household waste.

• The Device: The main device (the battery unit) must never be thrown in your household bin. It contains a Lithium-Ion battery, which is classified as hazardous waste. If it ends up in a landfill, it can leak toxic chemicals or start fires.

• Correct Disposal: The device is Waste Electrical and Electronic Equipment (WEEE). You must take it to a proper disposal point. Most household recycling centres have a dedicated bin for small electronics and batteries. Alternatively, many supermarkets and all dedicated vape shops (including our own) will have battery recycling bins where you can safely dispose of your old device.

Frequently Asked Questions (FAQs)

Can I use my own e-liquid with the JNR P4 Stellarc?

Absolutely. That is one of its best features. It is a fully refillable system. Just make sure you use the correct type of e-liquid, which is a 50/50 VG/PG blend, to ensure the 1.2-ohm coil works perfectly.

How long does the 1200mAh battery last?

The battery life is excellent. For a moderate vaper, the 1200mAh battery should easily last a full day, and potentially even two days, on a single charge. Heavy vapers should still comfortably get through a full day.

How long does the JNR P4 2ml pod (coil) last?

This depends entirely on your e-liquid and vaping habits. If you use clear, non-sweet e-liquids and do not chain vape, a pod can last two or even three weeks. If you use very sweet, coloured e-liquids, you may only get one week before the flavour degrades.

What's the difference between the 2ml pod and the 10ml container?

The 10ml container is the main reservoir that you, the user, refill with your e-liquid. The 2ml pod is the "business end" that contains the coil and wick. The 10ml container automatically feeds e-liquid into the 2ml pod, so you do not have to. You only replace the 2ml pod when its built-in coil wears out.

Is the JNR P4 Stellarc 100K beginner-friendly?

Yes, it is an excellent choice for a beginner who wants to move on from disposables. Because it is inhale-activated (no buttons) and has a simple, clean refill system, it removes many of the complexities of older vape kits. It offers the simplicity of a disposable with the cost savings and flavour choice of a refillable kit.
