The UWell Caliburn G4 Pod Vape Device combines advanced functionality with sleek design for a premium vaping experience. Powered by a long-lasting 1300mAh battery and offering adjustable output between 5–35W, it features an animated display and two performance modes—Storm for dense clouds and Wave for steady, consistent output.
Constructed from durable aluminum alloy, the G4 supports a resistance range of 0.4–0.9ohm, delivering smooth flavor and satisfying vapor production. Its magnetic pod system, compatible with both Caliburn GPP and G3 Series pods, features a convenient side-fill design for mess-free refills and secure handling.
An adjustable airflow switch and draw-activated firing ensure easy customization and user-friendly operation. Compact yet powerful, the Caliburn G4 is ideal for both flavor chasers and cloud enthusiasts, making it a standout choice for vapers on the go.

The G4 is a clear generational leap: nearly 45% more battery capacity, a higher wattage ceiling, a colour display replacing the older monochrome screen, adjustable airflow (the G3 had none), and forward-compatible pod support. If you are currently using a G3, your existing pods work in the G4 without any changes.
The Caliburn G4 is the all-rounder in the Caliburn G4 lineup. Looking for something different?
How long does the Caliburn G4 battery last?
The 1300 mAh battery typically lasts a full day for moderate users (roughly 300–400 puffs). Heavy users vaping at higher wattage in Storm Mode may need a top-up in the evening. USB-C charging at 5V/2A brings the battery from empty to full in about 45 minutes.
Can I use Caliburn G3 pods in the G4?
Yes. The Caliburn G4 is fully backward-compatible with all Caliburn G3 series pods (0.4Ω, 0.6Ω, 0.9Ω). It also supports the newer GPP series pods. You do not need to buy new pods when upgrading from a G3.
What is the difference between Storm Mode and Wave Mode?
Storm Mode ramps up power for denser vapour and a stronger throat hit — better for cloud chasers. Wave Mode holds a steady, moderate output for a smoother, more consistent draw. You can switch between them using the device button.
Is the Caliburn G4 suitable for a beginner?
Yes. It supports draw activation (just inhale to fire), and the included 0.9Ω pod provides a tight MTL draw similar to a cigarette. The 0.4Ω pod offers a slightly looser draw with more vapour. Either option is straightforward to set up and use right out of the box.
Does VapeBest ship this product across Canada?
Yes. We ship to all provinces and territories via Purolator and UPS. Orders over $99 qualify for free shipping. In-stock items typically ship within 24 hours.
Which e-liquid should I use with the Caliburn G4?
Nicotine salt e-liquids work well with the 0.9Ω pod for a smooth MTL experience. Freebase e-liquids pair better with the 0.4Ω pod for more vapour. The maximum nicotine concentration allowed in Canada is 20 mg/mL per Health Canada regulations.
