Uwell Caliburn G4 Mini Pod Kit

The Uwell Caliburn G4 Mini represents everything that's brilliant about modern pod vaping - it's genuinely compact without sacrificing performance, and honestly, it's one of those devices that just works. This isn't your typical "mini" version that feels like a watered-down afterthought. The G4 Mini packs a proper 1100mAh battery and delivers up to 35W of power, making it ideal for both mouth-to-lung and restricted direct-to-lung vaping styles.

What sets this pod kit apart is how Uwell managed to cram serious functionality into something that weighs just 45 grams. You're getting genuine flavour quality here, not the muted taste you might expect from a smaller device. The 2ml refillable Caliburn G3 pods use integrated mesh coils that actually deliver on flavour - I've been genuinely impressed with how well these perform compared to other setups I've used.

Whether you're new to vaping or looking for a reliable backup device, the Caliburn G4 Mini strikes that sweet spot between portability and performance. It's the kind of pod kit that'll sit comfortably in your pocket without you constantly worrying about battery life or flavour quality.

Key Features

Battery and Power Output

The 1100mAh integrated battery is genuinely impressive for a device this size. You're looking at easily a full day of moderate use, sometimes stretching into a second day depending on your vaping habits. The 35W maximum output gives you enough power for a satisfying vape without being overwhelming - it's perfectly calibrated for the pod system.

Pod System and Capacity

Each pod holds 2ml of e-liquid, which complies with UK TPD regulations whilst giving you decent capacity between refills. The integrated mesh coils are built into the pods, so replacement is straightforward - no fiddly coil changes required.

Charging and Connectivity

USB Type-C charging is a welcome addition. It charges relatively quickly, and the port feels solid - none of that wobbly connection you sometimes get with cheaper devices.

Size and Portability

At 11cm tall and 2.4cm wide, it's genuinely pocket-friendly. The 45-gram weight means you'll barely notice it's there, which is exactly what you want from a portable device.

Dual Vaping Styles in One Device

The adjustable airflow system lets you switch between mouth-to-lung and restricted direct-to-lung vaping. This flexibility means you're not locked into one style - you can adjust based on your mood or the e-liquid you're using.

Enhanced Flavour Technology

Uwell's mesh coil integration genuinely makes a difference to flavour quality. The coils are built into each pod, ensuring consistent performance throughout the pod's lifespan. You won't experience that gradual flavour decline you get with some vapes.

Compact Design Without Compromise

Most "mini" versions feel like compromised versions of their bigger siblings. The G4 Mini doesn't - it feels like a properly engineered device that happens to be smaller, rather than a cut-down version with missing features. It's available in 12 daring designs, too, so there's a colour for every customer!

Why Choose The Caliburn G4 Mini vape

The main reason to choose the Caliburn G4 Mini is reliability combined with genuine portability. This isn't just marketing speak - the device consistently performs well without the common issues you might face with other compact pod systems. Battery life is genuinely good for the size, and the flavour quality doesn't suffer despite the compact form factor.

Compared to other mini pod systems, the G4 Mini offers better battery capacity and more consistent performance. The build quality feels solid - it's not going to fall apart after a few weeks of regular use. The pod system is also more economical than many alternatives, as the integrated coils tend to last well when you're using appropriate e-liquids.

For beginners, it removes a lot of the complexity around coil selection and installation. For experienced vapers, it offers a dependable backup or stealth vaping option that doesn't compromise on the essentials.

How to Use and Maintain Your G4 Mini

Initial Setup

Remove the device from packaging and check the battery level - it usually comes partially charged. Remove the pod and fill it through the side-fill port, leaving a small air gap at the top. Let the pod sit for 5-10 minutes before first use to ensure the coil is properly saturated.

Daily Operation

The device is draw-activated, so there's no fire button to worry about. Simply inhale from the mouthpiece and the device will activate automatically. Adjust the airflow slider on the side to find your preferred draw resistance.

Refilling Process

Remove the pod from the device, locate the rubber stopper on the side, and carefully lift it. Fill slowly to avoid air bubbles, replace the stopper, and reinsert the pod. Give it a minute or two before vaping if you've let the pod run very low.

Maintenance Tips

Keep the charging port clean and dry. Wipe down the device regularly with a slightly damp cloth - don't use harsh chemicals. Replace pods when flavour starts to diminish or you notice a burnt taste. Clean the pod connection points occasionally with a cotton bud to ensure good contact.

Frequently Asked Questions

How long does the battery last on the Caliburn G4 Mini?

The 1100mAh battery typically provides a full day of moderate use, roughly 200-300 puffs depending on your vaping style and wattage. Heavy users might need to charge daily, whilst lighter users often get into a second day.

What's the difference between the G4 Mini and the regular G4?

The main differences are size and battery capacity. The Mini is more compact and lighter but maintains the same 35W output and pod compatibility. The regular G4 has a larger battery but is bulkier to carry around.

Can I use any e-liquid with this device?

The G4 Mini works best with e-liquids between 50/50 and 70/30 VG/PG ratios. Higher VG liquids might not wick properly in the pods, whilst very thin liquids could cause leaking. Nicotine strength is personal preference, but 6-20mg works well for most users.

How often should I replace the pods?

Pod lifespan varies based on usage and e-liquid type, but typically expect 1-2 weeks per pod with regular use. Sweet or dark e-liquids will reduce pod life, whilst clearer liquids tend to be gentler on the coils.

Is the Caliburn G4 Mini suitable for beginners?

Absolutely - it's actually one of the better starter devices available. The draw-activation removes complexity, there's no coil changing required, and the dual airflow options let you find your preferred vaping style without buying multiple devices.

Does it leak or have common problems?

Leaking is minimal if you follow proper filling technique and don't overfill. The most common issue is pods occasionally not making perfect contact, but this is usually solved by cleaning the connection points or gently adjusting the pod position.

What comes in the box with the G4 Mini?

You'll get the device itself, one 2ml pod (usually pre-installed), a USB Type-C charging cable, and user manual. Some retailers include additional pods or e-liquids as part of promotional offers.

How do I know when to charge the device?

There's an LED indicator that shows battery status. When it starts flashing or changes colour (depending on the specific model), it's time to charge. The device will also produce weaker vapour when the battery is low.
