This is the internal P4 vs P5 breakdown — both the JNR 100K Kit and the P5 GlassRock 100K Kit are part of the same JNR vapes 100,000-puff refillable platform. The same 10 prefilled flavors run on both devices; pick a starting flavor from the JNR Stellarc vape flavors hub before checkout — airflow on each hub shifts how the flavor reads, but the formula is identical across SKUs. That difference is easiest to hear on the two most polarising pods: the Sour Fcuking Fab flavor reads tangier on the P4's tighter draw, and what does Sour Apple Ice taste like shifts noticeably between the two chassis, while the sweeter Mexican Mango flavor barely moves.

JNR Stellarc 100K vs GlassRock 100K — Which JNR Kit to Buy
Same family, different draws. The P4 Stellarc has the premium curved screen and dual-battery voltage stability; the P5 GlassRock has the largest e-liquid reservoir in the JNR lineup.
JNR Stellarc 100K Vape Kit
JNR P5 GlassRock 100K
JNR Stellarc 100K Kit ($23.99) and JNR GlassRock 100K Kit ($24.99) both rate at 100,000 puffs with the same 10-flavor library at 5% salt nicotine. Stellarc differentiates with a curved Stellar-animation screen, 1,200 + 280 mAh dual-battery system (1,480 mAh combined), and tighter MTL-style airflow. GlassRock differentiates with a 1,000 mAh single-cell architecture, 64 mL reservoir (largest in the lineup), mini battery indicator, and open airflow. Pick by screen UX preference and airflow style — both deliver the same flavor library.
Spec-by-Spec Breakdown — Where Each Device Wins
Battery architecture — dual cell vs single cell
P4 Stellarc uses dual cells (280 mAh control + 1,200 mAh main = 1,480 mAh combined). P5 GlassRock uses a single 1,000 mAh cell. Stellarc holds voltage more stable across the full pod life because the chip/screen do not compete with the coil for power. GlassRock's simpler architecture has fewer failure points and charges faster. Stellarc wins on stability; GlassRock wins on charge speed (35-50 min vs 45-65 min).
E-liquid reservoir — 32 mL vs 64 mL pod
P4 Stellarc ships with a 32 mL pod. P5 GlassRock ships with a 64 mL pod — double the reservoir, the largest in the JNR lineup. For users running through pods quickly (200+ puffs/day), the P5 reservoir means fewer pod swaps per kit life. Both are rated 100,000 puffs across the full kit; the P5 reaches that rating with a single jumbo pod, the P4 may need a replacement mid-life depending on use.
Screen UX — curved Stellar animation vs mini battery indicator
P4 Stellarc has a curved high-contrast screen running the Stellar animation theme — battery percentage, juice level on the docked pod, and an ambient animation pattern visible from any front angle. P5 GlassRock has a small mini screen with a battery indicator only — no juice gauge, no animation. For users who like to know exactly where their device sits, Stellarc delivers more information density. For users who want a clean uncluttered device, GlassRock's minimal screen is sufficient.
Airflow style — tight MTL vs open
P4 Stellarc has a tighter mouth-to-lung (MTL) airflow that concentrates the flavor and produces a denser draw. P5 GlassRock has a more open airflow that lightens the flavor and produces a breezier draw. Same juice library on both, but the perception shifts: Stellarc reads as concentrated and dessert-like on rich flavors (Mexican Mango), GlassRock reads as refreshing and water-fresh on iced flavors (Watermelon Ice). Pick by preference; both are good.
Charge time — 45-65 min vs 35-50 min
P4 Stellarc charges in 45-65 min from 0 to 100% via USB-C at 5V/1A (the dual-battery package takes a bit longer). P5 GlassRock charges in 35-50 min — the fastest in the JNR lineup, thanks to the simpler single-cell architecture and slightly lower total capacity. Neither device supports pass-through (you cannot vape while charging on either).
Price per puff and economics
Stellarc: $23.99 ÷ 100,000 puffs = $0.24 per 1K puffs. GlassRock: $24.99 ÷ 100,000 = $0.25 per 1K puffs. Roughly identical price-per-rated-puff math. Replacement pod economics also similar: P4 pod $21.99, P5 pod $22.99. The $1 sticker difference is marginal — pick by feature preference, not pricing.
Flavor library compatibility
Both devices run the same 10-flavor library at 5% salt nicotine — Blue Razz Ice, Sour Apple Ice, Watermelon Ice, Miami Mint, Mexican Mango, White Peach Raspberry, Strawberry Kiwi, Strawberry Watermelon, Lemon Heads, Sour Fcuking Fab. <strong>Pods are NOT cross-compatible</strong> — the P4 Stellarc pod and P5 GlassRock pod have different chassis profiles and dock geometries. Pick a kit and stay within its pod family for replacements.

Largest reservoir in the JNR lineup
P4 Stellarc — premium screen, dual-battery voltage stability.
- ✓You want the curved Stellar-animation screen and the battery + juice readout the P5 lacks.
- ✓You value the dual-battery split (280 mAh control + 1,200 mAh main) for voltage stability from first puff to last.
- ✓You prefer a tighter MTL-style draw with a denser flavor concentration.
- ✓You want the slightly lower sticker price ($23.99 vs $24.99).
P5 GlassRock — largest reservoir, longest runtime per pod.
- •You want the largest e-liquid reservoir in the JNR lineup — 64 mL per pod.
- •You prefer an open, breezier airflow for cleaner fruit and mint notes.
- •You do not need a curved screen — a mini battery indicator is enough information.
- •You want the simplest possible architecture (single cell, fewer failure points).
