Uwell Caliburn G4 Pro - Pod Vape Kit

The Caliburn G4 Pro is the most advanced device Uwell has released in the G4 family, and it shows in almost every part of the experience. Released in 2025, it builds on everything that made the original G4 a go-to pod kit and adds a 2.51-inch touchscreen, a 1800mAh battery, 35W output, and Uwell’s PRO-FOCS 4.0 flavour technology. For vapers in Pakistan looking for a pod system that gives them genuine control over their setup without stepping into the complexity of a full box mod, the G4 Pro sits in a very specific and useful position in the market.

What Is the Uwell Caliburn G4 Pro?

The Caliburn G4 Pro is a pod kit built around the Caliburn GPP platform, which means it is compatible with the full range of GPP pods from 0.4 ohm through to 1.2 ohm. The device itself sits at 120.7mm tall with a 30 x 18.5mm body, weighs 78 grams, and uses an aluminium alloy shell across all eight colour variants. It is compact enough to carry daily but substantial enough that it does not feel cheap in hand.

What separates the G4 Pro from standard pod kits is the touchscreen. Most pod systems at this size give you a single button and a small LED indicator. The G4 Pro gives you a full-colour 2.51-inch touch display that controls wattage, vaping mode, themes, screen settings, and a puff counter. It is the kind of interface you would expect from a device twice the price.

Pod and Coil Options

The G4 Pro works with all Caliburn GPP pods, and the kit ships with two pods included — a 0.4 ohm pod pre-installed and a 0.6 ohm pod in the box alongside a USB-C charging cable and manual.

The 0.4 ohm pod runs best between 18 and 25W and delivers a restricted direct-lung draw. It is the right choice for vapers who prefer a more open airflow with good vapour production. The 0.6 ohm covers the territory between RDL and loose MTL and runs between 15 and 22W, making it the most versatile pod in the GPP range. The 0.8 ohm sits at 12 to 18W for a proper MTL draw, the 1.0 ohm drops to 10 to 15W for a closer cigarette-style feel, and the 1.2 ohm at 8 to 12W gives the tightest draw in the lineup, best paired with higher-strength nicotine salts.

Each pod uses a side-fill system except the 0.4 ohm, which supports both top and side fill. Airflow on the device is controlled by a rotating ring at the base of the pod, which gives stepless adjustment rather than preset notches.

Screen, Modes and Software

The touchscreen is the defining feature of the G4 Pro and it is more capable than most vapers would expect from a pod kit at this size. Three power modes are available: Waves, Storm, and Custom. Waves and Storm are preset draw curves optimised for different styles. Custom lets you shape the power delivery yourself using sliders, which is genuinely useful for getting the exact draw and warmth you prefer from a particular pod resistance.

The device also has a themes system tied to puff count milestones. New themes unlock at 5,000, 10,000, and 20,000 puffs. Screen timeout is adjustable, defaulting to three seconds. A battery saver mode and a clean UI option are both available. The interface supports eight languages.

Battery and Charging

At 1800mAh the G4 Pro has a larger battery than most pod kits in its size class, and the 5V/2.5A USB-C charging means it fills back up quickly rather than sitting on a cable for two hours between sessions. For everyday vapers in Pakistan who are relying on a single device throughout the day, the combination of a larger battery and fast charging removes the anxiety of running out mid-afternoon.

Why It Makes Sense for Vapers in Pakistan

Pakistan’s vaping community has moved well past starter kits. The demand for devices with real flavour performance, proper nicotine salt compatibility, and a longer battery life has grown steadily, and the Caliburn G4 Pro addresses all three in one device. The GPP pod platform, which is widely available through retailers like Vapes Direct and ICONA Vape, means getting replacement pods is not a problem. The broad resistance range means vapers switching from cigarettes can start at 1.2 ohm with high-strength nic salts and gradually move down as their preferences change.

The aluminium body also holds up better than plastic-shell pod kits in the heat, which matters during Pakistan’s summer months when cheaper devices tend to warp or develop connection issues from thermal stress.

Frequently Asked Questions

Is the Uwell Caliburn G4 Pro available in Pakistan?
Yes. The Caliburn G4 Pro is stocked by major vape retailers in Pakistan including Vapes Direct and ICONA Vape, available both in-store and for delivery nationwide.

What pods are compatible with the Caliburn G4 Pro?
The G4 Pro is compatible with all Caliburn GPP pods across the full resistance range from 0.4 to 1.2 ohm. The GPP Alpha pods are also compatible and offer extended coil life through AlphaCore technology.

Which resistance pod should I use with the G4 Pro in Pakistan?
For vapers transitioning from cigarettes, the 1.0 ohm or 1.2 ohm pods with a high-strength nicotine salt like 50mg are the closest experience to smoking. For regular vapers who have been on nic salts for a while, the 0.6 ohm or 0.9 ohm at 35mg is the most common daily setup.

Does the Caliburn G4 Pro work with nicotine salts?
Yes. The device is designed for nicotine salt e-liquids and 50/50 freebase across all pod resistances, and the MTL airflow options make it well-suited to higher-concentration nic salts.

How long does the battery last on a full charge?
The 1800mAh battery typically covers a full day of moderate use on a single charge. Fast USB-C charging at 2.5A means a full recharge takes under an hour in most cases.

What colours is the Caliburn G4 Pro available in?
The G4 Pro comes in eight colours: Desert Gold, Iron Grey, Stripe Black, Pearl Silver, Frost White, Ink Blue, Light Green, and Fantasy Pink.

For vapers in Pakistan who want a device that grows with their preferences, handles both MTL and RDL styles, and keeps up with daily use on one charge, it is one of the more complete options available at vapes direct now.
