Which Caliburn G4 Should You Buy?
Everyday carry & best value: The Caliburn G4 hits the sweet spot between features and price. Its 1300 mAh battery lasts a full day for most users, and the animated colour display gives you real-time battery, wattage, and puff data. Storm Mode pushes dense clouds while Wave Mode delivers a smoother, more consistent draw. If you are upgrading from a G3, this is the most natural step up.
Ultra-portable & screen-free: The Caliburn G4 Mini strips away the display and vaping modes in favour of a lighter, slimmer body that weighs just 46 g. It auto-adjusts output based on pod resistance, so there is nothing to configure — just draw and vape. A great choice for commuters and minimalists. Read our full G4 Mini review →
Touchscreen & full control: The Caliburn G4 Pro features a 2.51-inch shatterproof touchscreen with 6 customizable UI themes. It adds a third Custom vaping mode on top of Storm and Wave, letting you fine-tune wattage to your exact preference. The 1800 mAh battery means less time charging between sessions.

Maximum battery life: The Caliburn G4 Pro KOKO packs a 2000 mAh battery — the largest in the G4 range — inside KOKO's signature square design. It shares the Pro's touchscreen interface and three vaping modes, making it ideal for heavy vapers who need multi-day battery life without a mid-day charge.
Simple & affordable: The Caliburn G4 Classic is the most budget-friendly option in the series. With a 900 mAh battery, draw activation, and no screen, it focuses on delivering clean flavour through PRO-FOCS 4.0 technology without extra complexity. A solid starter kit for new vapers.
Key Technology: PRO-FOCS 4.0
Every Caliburn G4 device uses Uwell's fourth-generation PRO-FOCS (Professional Flavour Optimization Condensation System) technology. Uwell claims a 35% improvement in flavour reproduction over previous generations. The system optimizes airflow path geometry and coil heating consistency to extract more accurate flavour from your e-liquid. Combined with the leak-resistant side-fill pod design and the U² ultrasonic welding process, the G4 pods deliver cleaner, longer-lasting performance per fill.
Pod Compatibility Guide
All Caliburn G4 devices support the newer GPP series pods and are backward-compatible with Caliburn G3 pods, giving you flexibility if you are transitioning from an older device.
Available pod resistances include 0.4Ω (for a warmer, looser draw), 0.6Ω (balanced MTL/RDL), 0.9Ω (a tighter, cooler MTL draw), and 1.2Ω. GPP pods feature a side-fill silicone plug — no need to remove the pod from the device to refill. Browse all Caliburn pods and accessories →
Why Buy Caliburn G4 from VapeBest?
Frequently Asked Questions
Is the Caliburn G4 good for beginners?
Yes. The G4 and G4 Mini both support draw activation, so there are no buttons or menus to learn. The G4 Mini in particular is one of the simplest pod systems available — just insert a pod and inhale. For beginners who want a screen and more control, the standard G4 offers an intuitive interface without being overwhelming.
Can I use my old Caliburn G3 pods with the G4?
Yes. All Caliburn G4 devices — including the G4, G4 Mini, G4 Pro, G4 Pro KOKO, and G4 Classic — are backward-compatible with Caliburn G3 pods. All G4 devices also work with the newer GPP series pods.
What is the difference between Storm Mode and Wave Mode?
Storm Mode delivers a more intense, cloud-focused hit with higher power output. Wave Mode provides a smoother, more consistent draw at a steadier wattage. The G4 Pro and G4 Pro KOKO add a third Custom Mode where you set the exact wattage yourself.
How long does the Caliburn G4 battery last?
Battery life depends on usage and wattage. The standard G4 (1300 mAh) typically lasts a full day for moderate users. The G4 Pro KOKO (2000 mAh) can last two days or more with lighter use. The G4 Classic (900 mAh) and G4 Mini (1100 mAh) suit lighter vapers or those who keep a charger handy.
Does VapeBest ship Caliburn G4 across Canada?
Yes. We ship to all provinces and territories in Canada via Purolator and UPS. Orders over $99 qualify for free shipping. Most in-stock items ship within 24 hours of purchase.
Which e-liquid works best with the Caliburn G4?
Nicotine salt e-liquids (up to 20 mg/mL, the Health Canada maximum) work well with higher-resistance pods (0.6Ω and 0.9Ω) for a smooth MTL draw. Freebase e-liquids pair better with the 0.4Ω pod for a warmer, slightly looser hit. Both types are compatible across all G4 models.
