How long does the battery last and how do I charge it?

The built-in 1400mAh battery lasts most vapers a full day between charges. When it runs low, charge it over USB-C in around 45 minutes with 2A fast charging. Please note that a USB-C cable is not included in the box.

What is the difference between MTL and RDTL vaping?

MTL, or mouth to lung, is a tight draw much like a cigarette, and the 0.9 Ohm pod suits it well. RDTL, or restricted direct to lung, is a looser, airier draw, and the 0.4 Ohm pod is built for it. Adjust the airflow slider to fine-tune either style.

What e-liquid and nicotine strength should I use?

The Caliburn G4 Classic is designed for 50/50 e-liquid, which covers most nicotine salts and balanced freebase blends. Higher nicotine strengths suit the tighter MTL 0.9 Ohm pod, while lower strengths pair well with the airier RDTL 0.4 Ohm pod. The nicotine strength guide above helps you match a level to your needs.

Is this a disposable vape?

No. It is a rechargeable, refillable pod kit and a longer-lasting alternative to disposables. You refill the 2ml pod with your own e-liquid and recharge the battery over USB-C, so it saves money and waste over time.

Uwell Caliburn G4 Classic Pod Kit

Q: Which pods does the Caliburn G4 Classic use?

It uses Uwell Caliburn G3 refillable pods, and both a 0.4 Ohm and a 0.9 Ohm pod come included. It also works with the wider Caliburn G3 and GPP pod range. Each pod has a built-in mesh coil, so you replace the whole pod once the coil fades.

Product Summary

The Uwell Caliburn G4 Classic is a compact refillable pod kit with a 1400mAh battery, a 5W to 35W output range and a 2ml top-filling pod. It charges over USB-C in around 45 minutes and fires by inhale or a single button, with Smart Mode setting the wattage for you. The included 0.4 and 0.9 Ohm pods cover both RDTL and MTL vaping, while adjustable airflow tunes the draw. Pair it with 50/50 e-liquid. Ideal as an easy all-day refillable for anyone moving on from disposables, in four colours.

The Uwell Caliburn G4 Classic is a compact refillable pod kit built for easy, all-day vaping. It packs a 1400mAh battery, a 5W to 35W output range and a 2ml top-filling pod. So you simply add your own e-liquid, drop the pod in and start vaping.

Two refillable pods come in the box, a 0.4 Ohm and a 0.9 Ohm. Because of this pairing, the kit covers both RDTL and MTL vaping from the start. Smart Mode then sets the wattage for you, so there is little to learn. However, note that a USB-C cable is not included.

Who is the Caliburn G4 Classic for?

Choose it if:

You want a simple refillable pod kit with a long-lasting battery for daily carry
You are leaving disposables behind and want an easy mouth to lung draw
You like to tune the inhale with adjustable airflow and a looser RDTL option

Look elsewhere if:

You are chasing big clouds: a sub-ohm kit suits direct to lung vaping better
You never want to refill or recharge: this kit needs your own e-liquid and a USB-C cable

A Compact Everyday Pod Kit

The Caliburn G4 Classic keeps a slim, rounded body that sits comfortably in the hand. It measures 113 by 29 by 17mm and weighs just 67g. So it stays light in a pocket or bag through the day. On top of that, a single button and a clean front panel keep the design simple.

The range comes in four understated finishes, so each one suits a low-key, classic look. In total, there are four colours to choose from:

Classic Black and Classic Silver for a timeless, neutral finish
Abyss Blue for a deep, cool accent
Alpine Green for a soft, natural tone

A Full Day of Power

The 1400mAh battery is generous for such a compact device. As a result, it comfortably covers a full day of vaping for most people. When it runs low, a USB-C cable then recharges it in around 45 minutes thanks to 2A fast charging.

You can also fire the kit in two ways. First, simply inhale on the mouthpiece to vape. Alternatively, press the single button instead. Meanwhile, Smart Mode reads each pod and sets the ideal wattage within the 5W to 35W range.

Caliburn G3 Refillable Pods

First, top-fill the 2ml pod, then click it into place and start vaping. Because the pods fill from the top, you can refill without removing the pod. Each pod uses a built-in mesh coil, so it heats e-liquid quickly for cleaner flavour.

The kit also includes two pods. The 0.4 Ohm pod gives a looser RDTL vape, while the 0.9 Ohm pod suits a discreet MTL draw. It also works with the wider Caliburn G3 and GPP pod range. We recommend pairing every pod with 50/50 e-liquid. Each option runs best at its own wattage, shown in the table below.

Caliburn G4 Classic Pod Compatibility
Caliburn GPP Pods	0.4Ω (35W), 0.6Ω (25W), 0.9Ω (15W), 1.2Ω (13W)
Caliburn G3 Pods	0.4Ω (5-25W), 0.6Ω (5-25W), 0.8Ω, 1.0Ω (5-10W)

Adjustable Airflow, Two Draws

The Caliburn G4 Classic gives you real control over the inhale. First, the adjustable airflow slider lets you tighten or open the draw. So you can set a snug MTL draw or a looser RDTL one. As a result, one small kit suits two different vaping styles.

For a tighter, cooler vape, close the airflow and fit the 0.9 Ohm pod. For more vapour and a warmer draw, open it up and use the 0.4 Ohm pod instead. In short, the kit adapts to how you like to vape.
