JNR P4 Stellarc 100K Not Working? Complete Troubleshooting Guide

The JNR P4 Stellarc 100K is a high-capacity, next-generation pod kit built for long-term vaping convenience. With its 100,000 puff potential, dual-flavour pod system, dual mesh coil, large auto-refill e-liquid capacity, Type-C charging, and smart curved display, it is designed to deliver strong flavour and long usage with minimal maintenance.

However, because the JNR P4 Stellarc 100K is a more advanced hybrid pod system, some users experience issues such as no vapour, charging problems, weak flavour, burnt taste, leaking, LED error flashes, or battery drain. Most of these problems are not faults but normal wear-and-tear or usage-related issues that can be fixed easily.

This guide explains why the JNR P4 Stellarc 100K stops working, how to diagnose each problem correctly, and how to fix it step by step. It is written for adult vapers who want clear answers without technical confusion.

Understanding How the JNR P4 Stellarc 100K Works

Before troubleshooting, it helps to understand how the device functions. The JNR P4 Stellarc 100K is a rechargeable, auto-draw pod kit that combines a replaceable pod, auto-refill e-liquid container, and dual mesh coil system.

When you inhale, the airflow sensor activates the coil, which heats the e-liquid and produces vapour. Power is supplied by a rechargeable battery module, and the screen displays battery level, status, and alerts. If any part of this chain fails—battery, pod, coil, airflow, or sensor the device may appear “not working.”

Most faults come from pods, charging issues, or airflow blockage, not from the main device itself.

Quick Checklist Before You Start

Before assuming your JNR P4 Stellarc 100K is faulty, check the following:

• Make sure the battery is charged and the screen responds

• Confirm the pod is fully inserted and seated correctly

• Remove all protective stickers or seals from new pods

• Check for visible leaks, cracks, or liquid build-up

• Ensure you are using official JNR P4 Stellarc pods

Very often, these quick checks solve the problem immediately.

1. JNR P4 Stellarc 100K Not Firing (No Vapour on Inhale)

This is the most common complaint. You inhale, but no vapour is produced.

Why This Happens

• Battery is flat or very low

• Pod is not seated properly

• Pod is empty or coil has burnt out

• Airflow sensor is blocked by dust or condensation

• Internal protection system has stopped firing

How to Fix It

First, check the pod for e-liquid. If the pod is empty or tastes burnt, it must be replaced. Remove the pod and wipe the metal contacts on both the pod and device using a dry tissue, then reinsert it firmly. Recharge the device fully using a Type-C cable and a wall adapter. Clean the mouthpiece and airflow holes to remove condensation. If the issue remains, test with a new pod.

When to Replace the Device

If there is no vapour, no screen response, and no charging reaction even with a new pod and cable, the internal board may be faulty and replacement is recommended.

2. JNR P4 Stellarc 100K Not Charging

Charging issues prevent the device from powering the coil.

Common Causes

• Faulty or damaged USB-C cable

• Weak or incompatible charger

• Dirt or lint inside the charging port

• Battery protection triggered due to overheating

• Battery degradation after heavy use

How to Fix It

Try a different USB-C cable and wall plug. Clean the charging port gently with a dry cotton bud. Plug the device in and check for a charging icon or animation on the screen. If the device feels warm, unplug it and allow it to cool before charging again.

When to Replace

If the screen never lights up and there is no charging indicator after multiple cables and plugs, the charging circuit or battery has failed.

3. Weak Vapour or Muted Flavour

If vapour output feels light or flavour is dull, the device is working but not optimally.

Why Vapour Feels Weak

• Battery charge is low

• Coil is worn from use

• Pod or refill container is nearly empty

• Airflow is partially blocked

• Chain vaping has overheated the coil

How to Fix It

Recharge the device fully. Check the pod and refill container levels. Replace the pod if flavour remains dull. Slow down puffing and leave short breaks between inhales. Clean the mouthpiece and airflow channels.

When to Replace the Pod

If flavour does not improve after charging and cleaning, the pod has reached the end of its life.

4. Burnt or Harsh Taste

A burnt taste means the coil is dry or damaged.

What Causes Burnt Hits

• Pod or refill container is empty

• Coil cotton has burnt

• Puffing too hard or too often

• Pod used beyond its lifespan

How to Fix or Prevent It

Stop vaping immediately when you taste burning. Check liquid levels and replace the pod if low. Take shorter, gentler puffs and avoid chain vaping. Keep the battery charged for stable heating.

Important Note

A burnt coil cannot be repaired. Replacing the pod is the only solution.

5. Leaking or Gurgling

Some condensation is normal, but leaking should not be ignored.

Why It Happens

• Condensation build-up

• Over-inhaling floods the coil

• Heat or pressure changes

• Pod seal damage

Easy Fixes

Remove the pod and wipe everything dry. Blow gently through the mouthpiece to clear excess liquid. Reinsert the pod securely. Store the device upright and away from heat. Replace the pod if leaking continues.

When to Worry

Liquid inside the battery or charging port is a safety risk—stop using the device.

6. Pod Not Detected or LED Error Flashes

Flashing lights usually indicate a connection or pod issue.

Common Reasons

• Pod not seated properly

• Dirty or wet contacts

• Flooded coil

• Faulty pod

What to Do

Remove the pod, clean contacts, and reinsert firmly. Clear condensation and recharge the battery. Try a fresh pod if errors continue.

When to Replace the Device

If all pods show errors, the internal sensor or chipset may be damaged.

7. Auto-Firing or Device Heating Up

This is a safety-critical issue.

Causes

• Airflow sensor stuck

• Liquid inside device

• Internal short circuit

Immediate Actions

Remove the pod immediately. Dry the device thoroughly and let it cool on a safe surface. If it continues to activate on its own—even without a pod—stop using it and replace the device.

8. Airflow Too Tight or Too Loose

Airflow affects flavour and satisfaction.

Why This Happens

• Condensation in airflow path

• Pod misalignment

• Normal pod-to-pod variation

How to Improve Airflow

Clean airflow holes, reseat the pod, and clear condensation. Adjust puff strength to suit the draw. Try another pod if airflow feels off.

9. Battery Draining Faster Than Expected

High-capacity devices still depend on usage habits.

Normal vs Not Normal

Long puffs, chain vaping, and cold or hot environments drain batteries faster. Over time, all batteries degrade.

Tips to Extend Battery Life

Avoid chain vaping, fully charge before long sessions, store at room temperature, and replace faulty pods. If battery life becomes very short even with light use, replacement is advised.

10. Flavour Mixing After Switching (Dual-Flavour Pods)

Some flavour overlap is normal in dual-flavour systems.

Why This Happens

• Shared coil and chimney

• Wick holding previous flavour

• Rapid switching

How to Get Cleaner Flavour

Switch fully to one flavour, take several puffs to clear residue, and use fresh pods for best flavour separation.

When to Replace the JNR P4 Stellarc 100K

Replace the device if:

• It does not power on or charge

• It overheats or auto-fires repeatedly

• Multiple pods are not detected

• Liquid has entered the device body

• It has suffered water or impact damage

Final Thoughts

The JNR P4 Stellarc 100K is a powerful long-lasting pod system, but like all high-puff vapes, it relies on proper pod condition, airflow, and battery health. Most issues are pod-related and easy to fix. By following this guide, users can confidently diagnose problems, restore performance, and understand when replacement is necessary, ensuring a better and safer vaping experience.
