Quick tip · before you start
First-use calibration: take a single full charge cycle (0 to 100%) before extended use. This teaches the on-device state-of-charge gauge the actual cell capacity and improves percentage-readout accuracy for the rest of the device life.
Unbox and authenticate
Open the JNR retail box. Inside you should find: one sliding hub, one prefilled pod (flavor selected at checkout), one USB-C charging cable, the JNR authentication card, and the printed Quick Start guide. The hub may have a thin protective film over the curved screen (P4) or the mini battery indicator (P5) — peel it off. Locate the scratch panel on the outer carton — scratch the silver coating to reveal a verification code. Enter the code at the JNR authentication portal — it returns "Genuine" in under 5 seconds. If the portal returns "unknown" or "previously verified," email service@vapejnr.com with the code and order number for cross-check.
Charge the hub to 100% before first use
JNR devices ship in a partial-charge state (typically 30-50%) to comply with international shipping regulations on lithium-ion cells. Best practice for first use: a single deliberate 0-to-100% charge cycle. Plug into USB-C with a 5V/1A wall adapter (a standard phone charger block works perfectly). P4 Stellarc takes 45-65 minutes from empty to full; the side LED transitions red solid → red blinking → blue pulsing → green solid. P5 GlassRock takes 35-50 minutes; the mini battery indicator fills progressively. Do not skip this — the calibration improves percentage-readout accuracy for the rest of the device life.
Snap the prefilled pod onto the magnetic dock
Hold the JNR hub upright with the magnetic dock at the top. Take the prefilled pod and align the contact pins on the pod base with the contact pins on the hub dock — they are color-coded and indexed so they only seat one way. Push the pod down onto the dock with a firm motion until you hear or feel a click — that means the magnets have engaged and the contact pins are properly seated. The pod should not wobble or tilt; if it does, the seat is incomplete — slide off, wipe contacts with a dry cloth, re-seat with a firmer snap.
Take a primer puff to prime the cotton
Before your first real inhale, take a single shallow primer puff — a 2-second draw without inhaling. This pulls juice from the reservoir through the auto-feed channel into the cotton around the coil, ensuring the first proper inhale produces consistent vapor density rather than a thin or dry initial hit. If you see no vapor on the primer puff, take 2-3 more primer puffs at 5-second intervals to give the cotton time to saturate. Once a primer puff produces visible vapor, the device is ready for normal use.
⚠ WARNING
If the device does not produce any vapor after 5 primer puffs at 5-second intervals, do not continue chain-puffing — this can dry the cotton and cause a burnt taste. Instead, slide the pod off, check the dock contact pins for contamination, wipe with a dry cloth, and re-seat firmly. If primer puffs still produce no vapor, the pod may have a defect — file a warranty claim with photo.
Draw-activated inhale — no buttons
JNR P-series devices are draw-activated — there are no power buttons. Inhale through the mouthpiece and the coil fires automatically. For optimal vapor density: draw at moderate intensity for 2-3 seconds, then inhale into your lungs. Avoid aggressive chain-puffing (5+ rapid back-to-back puffs) — give the coil 8-10 seconds between draws to re-saturate the wick. The dual-mesh coil tuned by the JNR ProFire chip auto-adjusts wattage per pod SKU, so flavor consistency holds across the full pod life.
Read the screen — battery and juice state
The P4 Stellarc curved screen displays battery percentage on the hub, juice level on the docked pod, and the Stellar animation pattern. The screen wakes when you inhale and goes dark 5-10 seconds after the last draw to preserve battery. P5 GlassRock has a simpler mini battery indicator on the front of the hub — battery level only, no juice gauge (visually inspect the pod for juice level). On both devices, when the battery LED goes red solid, charge soon (under 10% remaining). When the on-screen juice gauge (P4) or visible pod reservoir (P5) reads near empty, plan a pod replacement.
Swap pods mid-life — flavor changes
When the pod is empty or you want to switch flavors, the JNR refillable design makes it simple: slide the pod down off the magnetic dock. Wipe both the hub contact pins and the new pod's contact pins with a dry lint-free cloth (microfiber is ideal). Snap the new pod onto the dock with a firm magnetic engagement. Take 2-3 primer puffs to prime the new cotton. The hub retains its battery charge and any settings across pod swaps — pod changes do not reset hub state. Replacement pods are $21.99 (P4) or $22.99 (P5) and ship same-day from Sacramento.
Daily care — storage, cleaning, and routine
Store upright when not in use — never upside-down or sideways (gravity can cause juice migration and pod leaks). Charge at room temperature (68-77°F); avoid hot cars and freezing pockets. Use the 20-80 charging rule when possible (plug in at 20%, unplug at 80%) to extend cell lifespan by 30-50% over aggressive 0-to-100 cycling. Wipe the dock contacts with a dry cloth whenever swapping pods to prevent contamination buildup. For long storage breaks (multi-week), charge to 40-60% and store in a cool dry place.
"Pull it out of the box, charge it once, snap the pod on, inhale. JNR is designed to be that simple — the engineering is in the consistency, not the complexity."

RELATED ACROSS THE JNR VAPE CATALOG
The setup instructions in this guide apply to every kit in the JNR vape lineup. The JNR vape Stellarc 100K Kit ships with one prefilled pod in your selected flavor; the P5 GlassRock Kit ships with the larger 64 mL pod. Either kit can be reflavored later — the full JNR vape flavors menu is the canonical list. First reorder ships from Sacramento warehouse; see per-state delivery windows on JNR Vape Near Me.
FAQ
Common JNR Vape Questions
How do I turn on my JNR vape?
JNR P-series devices are draw-activated — no power buttons. Inhale through the mouthpiece and the coil fires automatically. The screen (P4) or LED (P5) wakes when you draw and sleeps after 5-10 seconds of inactivity.
Do I need to charge my JNR vape before first use?
Yes — best practice is a single deliberate 0-to-100% charge cycle before extended use. JNR devices ship in a partial-charge state (typically 30-50%) for shipping safety. The first full cycle calibrates the on-device state-of-charge gauge and improves percentage-readout accuracy for the rest of the device life.
How do I dock the pod on a JNR Stellarc?
Hold the hub upright, align the contact pins on the pod base with the pins on the hub dock (they are indexed so they only seat one way), push down with a firm motion until you hear or feel a click. The pod should not wobble or tilt — if it does, slide off, wipe contacts, re-seat.
How do I swap flavors on a JNR vape?
Slide the current pod off the magnetic dock. Wipe both the hub and new pod contact pins with a dry lint-free cloth. Snap the new pod onto the dock. Take 2-3 primer puffs to prime the new cotton. Hub settings and battery state are preserved across pod swaps.
Can I use the pod without the hub?
Yes, but with limitations. The pod is draw-activated and works standalone. You lose the screen / LED indicator, the JNR ProFire chip-assisted tuning, and the auto-feed reservoir efficiency — but the pod still produces vapor for backup use. Best for emergency carry; not recommended as primary use.
How long does the first JNR pod last?
Each prefilled pod is rated for approximately 50,000 puffs (controlled conditions). Real-world: 30,000-38,000 puffs. At 150 puffs/day, roughly 7-8 months per pod. The P5 GlassRock kit ships with a 64 mL pod (double the P4 starter pod), so the first pod on a P5 lasts about twice as long.
