How To Use JNR P4? Step-By-Step Guide to the Stellarc 100K

• Khan Afridi

The JNR P4 Stellarc 100K (often simply called JNR P4) is a hybrid prefilled pod kit that combines the convenience of a disposable with the flexibility of a refillable, replaceable pod system. It’s built for vapers who want huge puff counts, dual flavours, and lower running costs than constantly buying single-use disposables.

With up to 100,000 puffs, a total of 64ml e-liquid, dual-flavour pods, 1.2Ω dual mesh coil, 1200mAh Type-C rechargeable battery, and an animated curved screen, the JNR P4 is one of the most advanced high-puff pod kits on the market.

If you’ve just bought a JNR P4 and you’re wondering how to set it up, how to install the pods, how to refill using the bottles, how to switch flavours and how to troubleshoot issues, this guide walks you through everything step by step.

What Is the JNR P4 Prefilled Pod?

The JNR 100K P4 Stellarc is described by the brand as a “flexible hybrid” – it behaves like:

  • an integrated disposable,

  • a refillable pod vape, and

  • a replaceable prefilled pod kit,

all in one device.

Key Specs & Features

From official and major retailer listings, the JNR P4 Stellarc 100K offers:

  • Puff count: up to 100,000 puffs per kit

  • Total e-liquid: 64ml:

    • 2 × 2ml replaceable prefilled pods

    • 2 × 10ml auto-refill containers

    • 4 × 10ml JNR e-liquid bottles (to refill the containers)

  • Battery: 1200mAh rechargeable (often detachable in some listings) with USB-C fast charging

  • Coil: 1.2Ω dual mesh coil for consistent, smooth MTL vapour

  • E-liquid: 2% (20mg) nicotine salt, US-developed flavours, MHRA-certified in certain SKUs

  • Dual-flavour system: each kit can run two flavours, with dual pods and dual refill containers

  • Auto-refill pod system: the 10ml container automatically feeds the 2ml pod, so you don’t have to manually refill the pod during normal use

  • Screen & controls: animated curved display showing battery life, puffs, and settings; inhale-activated firing

  • Airflow: adjustable airflow to tune the draw from tight cigarette-like to more open

In short: JNR P4 is a long-term, dual-flavour, hybrid pod kit that can be refilled using supplied bottles and can have its pods replaced, but still keeps the simplicity of a compact, all-in-one device.

Step-By-Step Guide: How to Use the JNR P4 Pod

Step 1: Unboxing & Preparation

A typical JNR P4 Stellarc 100K kit includes:

  • 1 × JNR P4 Stellarc 100K device

  • 2 × 2ml replaceable prefilled pods (dual-flavour)

  • 2 × 10ml replaceable auto-refill containers

  • 4 × 10ml JNR nic salt e-liquid bottles (2 for each flavour)

  • 1 × USB-C charging cable (varies by retailer)

  • 1 × user manual

Before Your First Use

  1. Remove the outer shrink wrap and open the box.

  2. Take out the device, pods, refill containers and 10ml bottles.

  3. Check for any visible damage or heavy leaks.

  4. If there’s a silicone plug on pod mouthpieces or protective caps, remove them.

  5. Make sure any stickers covering contacts or airflow are peeled off so the pods can connect and breathe correctly.

Step 2: Charging the Device

The JNR P4’s 1200mAh battery is designed to power the dual mesh coil through large amounts of e-liquid. It arrives with some charge, but it’s best to fully charge it before serious use.

How to Charge JNR P4

  1. Locate the Type-C charging port on the device.

  2. Plug in the USB-C cable and connect the other end to a reliable 1–2A wall adapter.

  3. The animated curved screen should light up and show a battery icon / charging animation.

  4. Leave the device charging until the battery indicator shows full.

Charging Safety Tips

  • Charge on a flat, non-flammable surface.

  • Avoid charging inside beds, under pillows, or on soft furniture.

  • Do not use frayed or very cheap unbranded cables.

  • Unplug once fully charged.

  • If the device becomes excessively hot, unplug and let it cool before trying again.

A healthy battery ensures strong vapour, stable performance and full use of the 64ml e-liquid capacity.

Step 3: Inserting the Pod

The JNR P4 pods are a little different to simple disposables. Each “pod unit” is actually a 2-part system:

  • A 2ml prefilled transparent pod (tank)

  • A 10ml auto-refill container attached behind or beneath it

The device uses magnets / slots to hold these pods securely.

How to Install a JNR P4 Pod

  1. Identify which pod / flavour you want to install first.

  2. Align the pod’s base and contacts with the pod bay on the device.

  3. Gently slide the pod in until the magnets pull it into place or it clicks.

  4. Give it a light tug to ensure it’s properly seated and not loose.

  5. If you’re setting up both flavours, repeat the process with the second pod on the other side (depending on layout).

With the pod installed and the battery charged, the auto-refill system will start feeding e-liquid into the 2ml visible tank from the larger 10ml reservoir as you vape.

Step 4: Refilling the Refill Containers (Using the 10ml Bottles)

One of the reasons the JNR P4 can reach up to 100,000 puffs is that it’s refillable in a controlled way. Instead of refilling little pods directly, you refill the 10ml containers using the supplied 10ml JNR bottles.

How to Refill a JNR P4 Refill Container

  1. Remove the pod unit from the device (if required by design to access the container).

  2. Locate the refill container’s silicone plug or fill port.

  3. Gently open the plug.

  4. Take the matching 10ml JNR bottle (same flavour) and insert the nozzle into the fill port.

  5. Slowly squeeze e-liquid into the container until it is almost full (don’t overfill).

  6. Reseal the silicone plug firmly to avoid leaks.

  7. Reinstall the pod / container module back into the device.

The auto-feed mechanism will then keep the 2ml pod topped up during use, so you don’t have to constantly refill.

Best practice: always refill with JNR’s own 10ml bottles or compatible e-liquid with the correct nicotine strength and VG/PG ratio recommended by JNR.

Step 5: Switching Flavours (Dual-Flavour Pods)

The JNR P4 Stellarc is designed as a dual-flavour pod system:

  • You have two pods, each capable of holding a different flavour.

  • Some kits even include matched dual-flavour combinations (e.g. Peach Mango Pineapple / Watermelon Mango, Blue Razz Cherry / Blueberry Raspberry, etc.).

How to Switch Flavours on JNR P4

Depending on the exact version:

  1. Either switch pods in the device bay, or

  2. Use any on-screen selection or physical selector if the device allows fast switching.

General approach:

  • Look at the curved screen – many versions display which pod / flavour is active.

  • Start drawing on the mouthpiece with gentle puffs.

  • Allow 3–6 puffs for the new flavour to fully take over, as there might be a brief mix with the previous flavour in the airflow path.

Step 6: Start Vaping

The JNR P4 is inhale-activated – there is no fire button to press.

How to Vape JNR P4 Correctly

  1. Place the mouthpiece gently between your lips.

  2. Take a slow, steady mouth-to-lung (MTL) draw, similar to puffing on a cigarette.

  3. Avoid hard, fast pulls:

    • Too much suction can flood the pod and cause gurgling or spitback.

  4. Use the adjustable airflow:

    • Turn/slide towards a smaller opening for a tighter, more cigarette-like draw.

    • Turn/slide towards a larger opening for a looser, airier vape.

  5. Leave a few seconds between puffs to let the 1.2Ω dual mesh coil re-saturate with e-liquid.

Vaping with proper technique extends the life of your pods, reduces the risk of burnt hits, and keeps the flavour clean.

Step 7: When & How to Replace Pods

Even with the large total capacity and auto-refill design, pods are consumables. Over time, the coil inside each JNR P4 pod will wear out.

Signs It’s Time to Replace a JNR P4 Pod

  • Flavour becomes muted, dull or “off” even when the container still has liquid.

  • You notice burnt or harsh taste that doesn’t go away after a few puffs.

  • The pod is cracked, damaged or leaking heavily.

  • The device shows error indications for a specific pod.

How to Replace

  1. Remove the pod from the device.

  2. Dispose of it according to your local electronic / vape waste guidelines.

  3. Open a new JNR P4 Stellarc replacement pod.

  4. Fill the associated container with the matching 10ml bottles if needed.

  5. Insert the new pod into the device until it clicks/magnetically locks.

  6. Allow a minute or a few gentle puffs for the coil to saturate.

Maintenance & Safety Tips for JNR P4

1. Keep the Device Clean and Dry

  • Regularly wipe:

    • Mouthpiece

    • Pod exterior

    • Inside of the pod bay

    • Contact points

  • Remove condensation with a tissue; don’t use water or cleaning sprays.

2. Only Use Compatible Pods & E-Liquids

  • Stick to official JNR P4 Stellarc pods and JNR e-liquid bottles, or e-liquids with similar specs recommended by the manufacturer.

  • Don’t force non-compatible pods into the device.

3. Charge Safely (Avoid Overcharging)

  • Use reliable USB-C cables and wall adapters.

  • Avoid leaving it charging unattended for long periods.

  • Keep away from extreme heat while charging.

4. Store in the Right Conditions

  • Store your JNR P4 at room temperature.

  • Avoid hot cars, radiators, or very cold environments.

  • Keep upright where possible to reduce the chance of seepage.

Troubleshooting Your JNR P4

1. Device Not Charging

Possible causes:

  • Damaged USB-C cable or wall adapter

  • Dust or lint blocking the Type-C port

  • Battery at the end of its usable life

What to do:

  1. Try a different USB-C cable that you know works with other devices.

  2. Try a different wall adapter or power source.

  3. Gently clean the Type-C port with a dry cotton bud.

  4. Put the device on charge for 20–30 minutes, then check if the screen shows a battery icon.

If there is still no response, the battery or internal board may be finished and it might be time to replace the device.

2. No Vapour When Inhaling

Common reasons:

  • Battery is completely flat

  • Pod not fully seated / poor contact

  • Auto-refill container and pod are both empty

  • Airflow holes or mouthpiece blocked

Fix steps:

  1. Fully charge the JNR P4.

  2. Remove and reinsert the pod, making sure it’s seated firmly.

  3. Check the 2ml pod window and 10ml container – if they look empty, refill container or replace pod as appropriate.

  4. Clean the mouthpiece and airflow slots with a tissue.

  5. Take slow, gentle puffs and watch the screen for any error messages.

If still no vapour, the pod or coil may be dead – replace the pod. If both pods fail and the device doesn’t fire at all, the device may have reached end-of-life.

3. Burnt or Harsh Taste

Why it happens:

  • The pod is running almost dry.

  • The coil has reached end-of-life after heavy use.

  • You’re chain vaping without letting the wick re-saturate.

What to do:

  1. Stop using the pod as soon as you taste burnt cotton.

  2. Check that the auto-refill container still has e-liquid. If empty, refill using the 10ml bottle.

  3. If there is liquid but the burnt taste persists, the coil is damaged → replace the pod.

  4. On the new pod:

    • Avoid chain-vaping very quickly.

    • Leave a few seconds between puffs.

    • Keep an eye on liquid levels in both pod and container.

Once a mesh coil inside a pod is burnt, flavour will not recover.

FAQs 

How long does the JNR P4 battery last on one charge?

The 1200mAh battery is designed to deliver many hours of typical MTL use on a full charge. Light to moderate users may get a full day or more per charge, while heavy users might recharge once or twice daily. The curved display makes it easy to monitor battery level.

Can I refill JNR P4 pods?

You don’t refill the 2ml pod section directly – instead, you refill the 10ml auto-refill containers using the supplied 10ml JNR e-liquid bottles. The containers then automatically feed the pods during use.

Trying to disassemble or force liquid directly into the pod is not recommended and can cause leaks or damage.

How many flavours can I switch between?

Each JNR P4 kit is configured for dual-flavour use:

  • Two 2ml pods

  • Two 10ml containers

  • Four 10ml bottles (two for each flavour)

So you can have two flavours active in one device. If you want more variety, you can keep extra pods pre-filled with other flavour combinations and swap them as you like.

How many puffs does JNR P4 really give?

The advertised 100,000 puffs is based on short, standardised puffs. In real-world use:

  • Light users taking short puffs may come close to the upper end.

  • Heavy users taking long draws will get fewer puffs – but still far more than a regular disposable because of the 64ml total e-liquid and refillable containers.

Is JNR P4 better value than standard prefilled pods or disposables?

Generally yes, for frequent vapers:

  • You get far more e-liquid and puffs per kit.

  • You can refill containers with the included bottles instead of throwing away a whole device.

  • Replaceable pods mean you keep the main device for longer and only swap the worn coil section.

Final Thoughts

The JNR P4 Stellarc 100K is a next-generation hybrid pod kit that combines:

  • Huge puff capacity

  • Dual-flavour flexibility

  • A refillable auto-feed system

  • Replaceable pods

  • And a smart curved display
