  1. $0.4\ \Omega$ Mesh Pod (Max $35\text{ W}$): Formulated specifically for RDL (Restricted Direct-Lung) vaping using $70/30\text{ VG/PG}$ or lower-strength freebase e-liquids. Delivers dense vapor clouds and a warm inhale.

  2. $0.6\ \Omega$ Mesh Pod (Max $25\text{ W}$): The versatile middle ground included in most kit bundles. Perfect for loose MTL or light RDL with $50/50$ freebase or mid-strength nicotine salts.

  3. $0.8\ \Omega / 0.9\ \Omega$ Mesh Pod (Max $15\text{ W} – 18\text{ W}$): Designed for a classic, smooth MTL draw with $50/50$ Nicotine Salts.

  4. $1.0\ \Omega / 1.2\ \Omega$ Mesh Pod (Max $12\text{ W} – 13\text{ W}$): Delivers a tight, cigarette-like draw optimized for high-strength Nicotine Salts ($35\text{ mg} – 50\text{ mg}$) and maximum battery conservation.

  5. Dual-Airflow Control System: Fine-Tuning Your Draw

  Customizing your airflow draw resistance on the Caliburn G4 Mini involves two independent mechanisms:

  1. Stepless Side Airflow Slider

  Located on the side of the device chassis, a smooth sliding toggle lets you fine-tune the intake hole millimeter by millimeter.

  • Slider Fully Closed: Restricts intake to a tiny pinhole, creating a tight, warm MTL draw with enhanced throat hit.

  • Slider Fully Open: Maximizes airflow for cool, effortless RDL draws with increased cloud volume and dense vapor.

  2. $180^\circ$ Pod Orientation Adjustment

  The base of the pod and the inner battery housing feature asymmetrical air inlets. Rotating the pod $180^\circ$ before inserting it magnetically alters the base airflow channel:

  • Orientation A (Tight Channel): Aligns air channels for restricted, authentic cigarette-style inhalation.

  • Orientation B (Open Channel): Expands the air pathway for looser, smoother draws.

  Combining the stepless side slider adjustments with the pod orientation yields total control over your airflow preferences.

  6. Nicotine Salt vs. Freebase E-Liquid Optimization

  Understanding which e-liquid type to pair with your chosen pod resistance is critical for preventing burnt coils, harsh throat hits, or e-liquid leakage.

  Nicotine Salt E-Liquids ($50/50\text{ VG/PG}$)

  Nicotine salts utilize lower pH formulations, allowing high nicotine concentrations ($20\text{ mg} – 50\text{ mg}$) to be inhaled smoothly without throat harshness.

  • Best Pod Pairings: $0.8\ \Omega$, $0.9\ \Omega$, $1.0\ \Omega$, and $1.2\ \Omega$ pods.

  • Vaping Style: Authentic Mouth-To-Lung (MTL).

  • Expected Performance: Instant nicotine absorption, ultra-smooth throat hit, and maximum battery conservation.

  Freebase E-Liquids ($60/40\text{ to }70/30\text{ VG/PG}$)

  Freebase nicotine offers a more pronounced throat hit at lower strengths ($3\text{ mg} – 12\text{ mg}$) and requires higher wattages to vaporize thicker Vegetable Glycerin (VG) bases.

  • Best Pod Pairings: $0.4\ \Omega$ and $0.6\ \Omega$ mesh pods.

  • Vaping Style: Restricted Direct-Lung (RDL) or loose MTL.

  • Expected Performance: Dense cloud production, intense flavor depth, and a warmer vapor output.

  7. Step-by-Step Guide: Setup, Refilling, and Maintenance

  1.Unpack and Inspect Device:

  Remove the Caliburn G4 Mini from its packaging. Inspect the pre-installed pod and locate the protective isolation sticker on the bottom contacts. Peel off this sticker before attempting to vape or charge.

  2.Fill the Pod Reservoir:Do not fire a dry coil.

  Locate the silicone fill port tab on the side of the G3/GPP pod. Lift the tab, insert your e-liquid bottle nozzle, and fill the chamber to approximately $80\% – 90\%$ capacity. Firmly seal the silicone plug back into place.

  3.Prime the Coil (10-Minute Wait):Essential step for coil longevity.

  Insert the pod back into the magnetic housing. Wait at least 10 minutes before taking your first draw. This allows the integrated meshed coil and organic cotton wick to saturate completely, preventing dry hits and premature coil burn.

  4.Inhale to Activate:

  With no buttons to press, simply place your lips on the mouthpiece and draw smoothly. The sensor will automatically trigger the firing mechanism and select the optimal wattage.

  8. Comparative Analysis: Caliburn G4 vs. G4 Mini

  Understanding the structural and functional differences between the flagship Caliburn G4 and the G4 Mini helps identify which device best fits your daily routine and budget.

  Target User	Enthusiasts wanting screen data and custom power	Minimalists wanting portability and effortless operation

  9. Troubleshooting & Maintenance Best Practices

  Preventing E-Liquid Leaks & Spitback

  1. Maintain Correct VG/PG Ratios: Thin e-liquids (below $50\text{ VG}$) may cause over-saturation in low-resistance coils, while thick liquids ($80+\text{ VG}$) can starve the wick and burn the coil.

  2. Avoid Overfilling: Leaving a $10\%$ air bubble inside the pod chamber maintains the vacuum seal necessary to prevent bottom-leakage.

  3. Clean Contact Pins Regularly: Inspect the gold spring-loaded pins inside the device well weekly. Wipe away minor condensation using a dry cotton swab.

  Decoding LED Indicator Signals

  • Flashes Red 3 Times: Short circuit detected. Remove the pod, clean contact pins, and re-insert. If issues persist, replace the pod cartridge.

  • Flashes Red 10 Times: Low battery voltage cutoff. Plug the USB-C cable into a $5\text{ V}/2\text{ A}$ charging source.

  • Flashes Blue 8 Times: Over-draw protection triggered (draw exceeded 8 seconds continuous firing).

  10. Economic & Environmental Benefits of Refillable Pod Kits

  Switching from single-use disposable vapes to an open-pod system like the Caliburn G4 Mini offers massive economic savings and environmental benefits:

  • Massive Cost Reductions: Buying $30\text{ mL}$ bottles of e-liquid and replacement pod packs costs roughly $70\% – 80\%$ less per month compared to buying equivalent disposable vapes daily.

  • E-Waste Reduction: Instead of discarding a lithium battery, microchip, and plastic casing every few days, you retain the $1100\text{ mAh}$ battery housing for years, discarding only tiny recyclable pod cartridges when the integrated coil expires.

  • Unmatched Flavor Choice: Open-pod systems unlock thousands of premium e-liquid flavors across various nicotine strengths, rather than locking you into pre-filled disposable options.
