The Uwell Caliburn G3 sorts a common problem for anyone moving away from disposables: finding a refillable pod kit that actually lasts. With its 900mAh battery and TPD compliant 2ml pods, this device delivers proper all-day reliability without the faff of constant charging or coil changes. At this price point, it's rare to find adjustable wattage and an OLED screen on a beginner-friendly kit.
Built around Uwell's Pro-FOCS flavour technology and mesh coils, the G3 handles both MTL vaping styles and looser restricted draws. The 5-25W power range covers 0.6Ω, 0.9Ω, and 1.2Ω pods, meaning you can fine-tune your vape rather than settling for factory defaults. Fast USB Type-C charging and magnetic pod connection keep daily use straightforward.
Suits ex-smokers wanting a cigarette-like draw, plus intermediate vapers who've outgrown basic pod systems but don't need sub-ohm cloud production. The built-in coil design eliminates messy replacements whilst the dual airflow settings cover tight MTL vaping through to relaxed restricted lung hits.
Key Features
- 900mAh Integrated Battery – 20% capacity increase over the G2 provides most vapers a full day between charges
- Refillable 2ml Pods – TPD compliant with CRC top-fill design and built-in coils for leak-proof performance
- MTL & RDTL Compatible – 0.6Ω and 0.9Ω pods included; 1.2Ω available separately for tighter draws
- Variable Wattage (5-25W) – Adjustable power output via OLED screen for personalised vaping
- Draw or Button Activated – Choose auto-draw, button fire, or enable both simultaneously
- FeCrAl Mesh Coils – Pro-FOCS technology delivers crisp flavour accuracy across freebase and nic salt liquids
- 2A Fast Charging – USB Type-C charges from flat to full in approximately 40 minutes
- Dual Airflow System – Rotate pod 180° to switch between restricted MTL and looser RDTL draw
Core Advantages
No-Leak Pod Architecture
The G3 introduces ultrasonic-welded pods with integrated coils that eliminate the traditional leak points found in removable coil systems. Users consistently report zero leaking even after weeks of daily use, solving one of the biggest complaints about earlier Caliburn models.
Pro-FOCS Flavour Restoration
Uwell's proprietary flavour adjustment technology extracts noticeably more detail from your liquids compared to standard pod coils. According to feedback from VAPEBUS customers, the flavour delivery is genuinely impressive, particularly with fruit and dessert e-liquids where finer notes can easily be muted by standard pod systems.
True All-Day Battery Life
The 900mAh cell reliably powers moderate vapers through a full day, with real-world testing showing 250+ puffs at 14W (0.9Ω pod). Even heavy users report making it to evening before needing a top-up, and the 40-minute fast charge means you're back in action quickly.
Beginner-Friendly Adjustability
The OLED screen removes guesswork by displaying wattage, resistance, battery level, and puff count. The device auto-selects optimal power for each pod (25W for 0.6Ω, 15W for
0.9Ω), but lets you fine-tune in 1W increments if preferred – perfect for those stepping up from disposables.
Flexible Draw Options
Lock the fire button and rely purely on auto-draw for a cigarette-like experience, or enable both methods for flexibility. The button lock prevents pocket firing whilst the instant
draw activation satisfies that immediate nicotine craving.
Cost-Effective Pod Longevity
Built-in coil pods last 1-2 weeks depending on e-liquid sweetness and usage, with users reporting consistent flavour right up until replacement. The all-in-one design means no fiddly coil changes or burnt cotton mishaps.
Available Colours
The Caliburn G3 comes in six aluminium alloy finishes:
- Silver – Classic metallic shine
- Grey – Subtle gunmetal tone
- Black – Stealthy matte finish
- Red – Bold statement colour
- Green – Fresh forest shade
- Blue – Deep ocean hue

Summary & Verdict
Ease of Use: Spot on for beginners. The auto-wattage selection means you can vape straight from the box, whilst the single-button interface keeps adjustments simple once you're ready to experiment.
Flavour Consistency: The Pro-FOCS tech genuinely makes a difference. Vapers moving from disposables consistently notice richer taste, and the flavour holds strong throughout the pod's lifespan rather than fading after a few days.
Battery Life: The 900mAh capacity handles moderate vaping (15-20 puffs per hour) for a full working day. Heavy users might need an afternoon top-up, but the 40-minute charge time keeps downtime minimal.
Build Quality: Solid aluminium construction with zero rattles or wobbles. The magnetic pod connection is reassuringly firm, and after weeks of pocket carry, our test units show no wear on the finish.
Value for Money: At this price bracket, you're hard-pressed to find comparable features. The combination of adjustable wattage, OLED display, and genuinely leak-proof pods puts it ahead of similarly priced competitors.
The G3 hits its target audience perfectly: ex-smokers wanting reliability and intermediate vapers seeking flavour quality without jumping to complicated mods. Does the job without pretending to be something it's not.
FAQs
How long does the Caliburn G3 battery last on a full charge?
Most vapers get a full day from the 900mAh battery with moderate use (around 200-250 puffs). At 14-15W with the 0.9Ω pod, expect 6-7 hours of regular vaping. The 0.6Ω pod at 24-25W drains faster, typically giving 4-5 hours. Heavy users should keep the USB-C cable handy for a quick 40-minute recharge.
Can I use any e-liquid with the Caliburn G3 pods?
The G3 works best with 50/50 VG/PG blends, which suit both the 0.6Ω and 0.9Ω pods. The 0.6Ω can handle up to 70/30 high-VG liquids for bigger clouds, though wicking may slow slightly. Stick to nic salts or freebase under 12mg for the 0.6Ω pod; higher strengths can feel harsh. The 0.9Ω and 1.2Ω pods are ideal for 10-20mg nic salts.
How do I stop the Caliburn G3 from leaking?
The integrated coil design prevents most leaks, but slight flooding can occur immediately after filling. Remove the pod and blow gently through the mouthpiece to clear any excess liquid from the airflow channel. Avoid overfilling past the maximum line, and always replace the silicone fill port cover properly to maintain the seal.
What's the difference between the 0.6Ω, 0.9Ω, and 1.2Ω pods?
The 0.6Ω pod (25W) delivers warmer vapour with bigger clouds – suited to restricted lung hits and freebase liquids. The 0.9Ω pod (15W) offers balanced MTL/RDTL performance with excellent flavour for nic salts. The 1.2Ω pod (10-12W) provides the tightest draw, closest to a cigarette feel, perfect for higher-strength nic salts and discreet vaping.
How often should I replace the Caliburn G3 pods?
Pods typically last 1-2 weeks depending on e-liquid sweetness and vaping frequency. When you notice a slight burnt taste or muted flavour, it's time to swap. Darker, heavily sweetened liquids shorten pod life to around 7-10 days, whilst clearer nic salts can push pods to 2+ weeks. The consistent flavour quality right up until replacement is a key advantage over cheaper pods.
Is the Caliburn G3 suitable for quitting smoking?
Yes, it's one of the better options for ex-smokers. The MTL draw with 0.9Ω or 1.2Ω pods closely mimics cigarette inhalation, whilst the instant draw activation satisfies that hand-to-mouth habit. Start with 10-20mg nic salt in a 50/50 liquid for the best cigarette replacement experience. The all-day battery and leak-proof design remove common frustrations that derail quit attempts.
Take the Caliburn G3 out of its packaging and disconnect the mouthpiece from the pod.
Insert the nib of your e-liquid bottle into the red silicone port and fill the pod up.
Click the mouthpiece back onto the pod.
Stand the Caliburn G3 upright and wait for five minutes to allow e-liquid to soak into the coil and “prime” it – this will help it to last longer whilst boosting flavour.
Inhale on the mouthpiece with or without holding the firing button to begin vaping.
When the Caliburn G3 needs a recharge, plug it in using a USB-C cable.
