JNR Stellarc 100K Review — Is It Really 100,000 Puffs?

The JNR P4 Stellarc 100K is one of the most technically ambitious disposable vapes on the market — and also one of the most misunderstood. That 100,000-puff claim is real in a cumulative sense, but the actual experience of using this device is closer to a semi-reusable pod mod than a traditional disposable. After three weeks of daily use — burning through two full pods, four refill bottles, and tracking every charge cycle — I can say the Stellarc delivers genuine value, but only if you understand what you're actually buying.

This review covers real-world puff counts, the auto-refill system in practice, battery performance, flavor quality over time, build quality issues I encountered, and how the Stellarc stacks up against both the P5 GlassRock and competing devices from Foger and Lost Angel.

What's in the Box

The Stellarc kit ships in one of the largest retail boxes I've seen for a "disposable." Inside you'll find:

• 1 × battery module (the main device with screen and charging port)
• 2 × pre-filled pods (2mL each, different flavors — one per pod)
• 2 × 10mL refill containers (attached to each pod)
• 4 × 10mL e-liquid bottles (matching the two pod flavors, two bottles each)
• 1 × USB-C charging cable
• Quick start guide

Each kit comes with two different flavors, so you're effectively getting a dual-flavor setup from day one. The only exception is the Watermelon Ice kit, which ships with the same flavor in both pods. For the full flavor lineup, see our JNR Vape Flavors guide.

Design & Build Quality

The Stellarc has a box-mod profile — wider and boxier than a typical stick-style disposable, but surprisingly comfortable in the hand thanks to rounded edges and the curved screen that wraps along one side. It doesn't look like a disposable. Pull this out in public and people will assume it's a reusable pod system, which in many ways it is.

The animated curved screen is the visual highlight. During draws, it displays a starlight animation along with your puff count and battery percentage. Between puffs, it shows a minimal clock-style display. It's not practical — you don't need animations on a vape — but it adds personality and makes the device feel more premium than its $23.99 price tag suggests.

Build quality is solid overall. The body has no flex or creaking, the USB-C port is centered and well-seated, and the twist-to-lock safety mechanism (rotate the pod to lock it in place) works reliably. My one build complaint: the pod-to-battery magnetic connection could be stronger. If you drop the device from more than about three feet, the pod can pop off — it won't break, but juice might leak from the connection point if the pod isn't fully seated when you pick it up.

The Auto-Refill System — How It Actually Works

This is the core technology that separates the Stellarc from every other disposable on the market, so it's worth explaining in detail.

Each pod consists of two attached chambers: a 2mL tank (where the coil sits and vapor is produced) and a 10mL refill container below it. During normal use, e-liquid feeds automatically from the 10mL container into the 2mL tank through a one-way valve. You don't need to press anything or flip the device — it's gravity-and-pressure assisted.

When the 10mL container empties (roughly every 2,000–2,500 puffs in my testing), you pull the silicone plug on the side of the container and pour in juice from one of the included 10mL bottles. The refill takes about 15 seconds. When the coil eventually degrades (around 7,000–8,000 puffs in my experience), you swap the entire pod — coil, tank, and container — for a fresh one.

What works well: The auto-feed mechanism is genuinely clever. You never get dry hits because the 2mL tank is always topped up from the larger container. No manual priming needed after assembly. The system is more reliable than I expected.

What's tricky: If you assemble the pod and refill container incorrectly on first setup, it's surprisingly difficult to separate them without spilling. Read the instructions before your first attempt. Also, the silicone plug can be fiddly with wet fingers — I found myself wiping my hands before every refill. For a complete setup walkthrough, see How to Use JNR Vape.

Real-World Puff Count: The 100K Reality Check

Let's address the headline claim directly. I tracked my first pod from fresh fill to burnt taste:

Milestone	Puff Count	Notes
Fresh pod (out of box)	0	Pre-filled 2mL tank + 10mL container
First refill container empty	~2,400	Refilled from included 10mL bottle
Second refill	~4,800	Flavor still strong
Slight flavor decrease	~6,000	Noticeable but still good
Burnt taste begins	~7,500	Time to swap pod

So one pod, fully utilized with refills, gave me approximately 7,500 puffs of quality vaping. The kit includes enough juice for roughly 15,000–20,000 puffs across both pods — far short of 100K, but still impressive for the price point. The 100,000 figure presumably assumes you'll buy replacement pods and bottles indefinitely using the same battery — which is technically possible since the battery module is detachable and rechargeable.

For reference, other reviewers have reported 7,464 puffs per pod (Ecigclick) and 20,000–25,000 puffs per pod swap cycle (VapingLand), though the latter figure seems to include multiple refills with significantly lighter draw styles. My 7,500-puff number is based on moderate use (200–300 puffs per day, mixed Regular and Boost mode).

Battery Performance

The 1,200mAh battery is adequate but not exceptional. At moderate use (200–300 puffs/day), I charged the device once every 1.5–2 days. Heavy vapers doing 500+ puffs daily will need to charge daily. USB-C charging takes approximately 60–90 minutes from empty to full.

The detachable battery is a unique feature worth emphasizing. The battery module separates from the pod section, which means:

• You can charge the battery while still having the pod accessible (no device downtime)
• If the battery degrades after months of use, you can theoretically replace just the battery
• The pod section contains its own 280mAh backup battery for basic functionality during charging

Compared to the P5 GlassRock's 1,900mAh battery, the Stellarc loses on raw endurance. If battery anxiety is a concern, the GlassRock is the better choice. If you prefer a more compact device, the Stellarc's smaller battery is the necessary trade-off.

Vaping Modes & Airflow

The Stellarc offers two power modes — Regular (30W) and Boost (40W) — toggled via the screen interface. Regular mode delivers a cooler, milder draw that's better for chain vaping and flavor preservation. Boost mode increases vapor production and throat hit, but burns through juice faster and accelerates coil degradation. I used Regular mode 80% of the time and saved Boost for occasional stronger hits.

The stepless airflow ring on the base of the device adjusts from tight MTL (mouth-to-lung) to a restricted DTL (direct-to-lung) draw. The range isn't as wide as a proper pod mod, but it gives enough control to find a comfortable draw resistance. Fully tightened, it's a satisfying cigarette-style draw. Fully open, it produces noticeably more vapor with slightly muted flavor.

Flavor Performance Over Time

This is where the Stellarc genuinely excels — and where the auto-refill system pays dividends.

With most disposables, flavor degrades steadily as the juice level drops and the coil accumulates sweetener residue. The Stellarc's constant-feed mechanism keeps the 2mL tank topped up, so you never experience that half-empty, slightly-burnt mid-life phase that plagues sealed disposables. Flavor quality from puff 100 to puff 5,000 was nearly identical in my testing.

The noticeable decline started around puff 6,000, when the coil mesh begins to degrade regardless of how well-supplied the juice is. By puff 7,500, there was a distinct "tired coil" taste — not burnt exactly, but a muted version of the original flavor. That's when it's time to swap to the second pod.

JNR's sugar-free formula contributes significantly here. Without sucralose gunking up the mesh, the coils last much longer than typical sweetened e-liquids allow. In my experience, JNR's coils outlast equivalent RAZ or Geek Bar coils by roughly 40–60% in puff count before flavor degradation.

Overall	8.2/10

Who Should Buy the Stellarc (And Who Shouldn't)

Buy the Stellarc if: You're a moderate-to-heavy vaper who wants long-term cost savings, don't mind a small learning curve with pod assembly, prefer a compact device, and value flavor consistency over raw battery capacity. The detachable battery is a genuine differentiator for users who keep devices for months.

Skip the Stellarc if: You want zero-effort disposable simplicity (try RAZ or Geek Bar instead), need maximum battery life per charge (get the P5 GlassRock), or rotate through many flavors frequently (JNR's 10-flavor lineup limits variety).

Stellarc vs GlassRock — Quick Comparison

	P4 Stellarc	P5 GlassRock
Battery	1,200mAh (detachable)	1,900mAh (built-in)
Size	Smaller, pocketable	Bulkier
Airflow	Stepless ring	Adjustable + e-liquid window
Screen	Animated curved display	Smart battery screen
Unique Feature	Detachable battery, twist-lock	Transparent body, larger battery
Kit Price	$23.99	$24.99
Best For	Portability, battery replacement	Battery life, airflow control

If you're choosing between the two, the Stellarc is the better first buy — it's $1 cheaper, more portable, and the detachable battery gives you flexibility. Upgrade to the GlassRock later if you find you need more battery endurance. The pods are not cross-compatible, but the flavor experience is identical.

Frequently Asked Questions

Is the JNR Stellarc actually 100,000 puffs?

Not from a single pod. Each pod realistically delivers 7,000–8,000 puffs before the coil degrades. The 100K figure represents cumulative use across multiple pod replacements on the same reusable battery module. A single kit (64mL) provides approximately 15,000–20,000 total puffs.

Can I use P5 GlassRock pods in the Stellarc?

No. P4 Stellarc and P5 GlassRock pods are physically different and not interchangeable. Each device requires its own specific pods. See our JNR Vape Pods guide for replacement options.

How often do I need to charge the Stellarc?

Every 1.5–2 days with moderate use (200–300 puffs/day). Heavy vapers (500+ puffs/day) will charge daily. Full charge takes 60–90 minutes via USB-C.

What happens if I assemble the pod wrong?

The pod and refill container can be difficult to separate once incorrectly assembled, and forcing them apart may cause leaks. Follow the included quick-start guide carefully on your first setup. The magnetic connection is orientation-specific.

Is the Stellarc worth it compared to regular disposables?

For cost per puff, yes. The $23.99 kit delivers 15,000–20,000 puffs, and replacement pods at $21.99 add another 7,000–10,000. A typical sealed disposable costs $18–$25 for 5,000–10,000 puffs with no replacement option. After your second pod purchase, the Stellarc's cumulative cost is significantly lower.
