Uwell Caliburn G2 Pod Vape Kit

Introduction

Uwell Caliburn G2 Pod Kit: a refillable MTL pod kit with a 750mAh battery, replaceable 0.8Ω and 1.2Ω mesh coils and an adjustable airflow wheel, £18.99. Best for adult vapers who want a tight, cigarette-like draw from nic salts and would rather replace a coil than a whole pod. Not ideal for anyone who wants a built-in-coil pod with zero upkeep, or a cloud kit.

The Uwell Caliburn G2 Pod Kit is the second-generation Caliburn G: same slim pen shape, bigger battery, a fill window on both sides, vibration alerts and an airflow wheel on the pod. Most UK shops have now sold out, so this page answers what owners still ask: which coils fit, how to stop leaks, and the weekly running cost.

Uwell Caliburn G2 Key Specs Customers Check

• Battery: 750mAh built-in. Reviewers get around 2.5ml to 3ml of e-liquid, or most of a day, per charge.
• Charging: USB-C, cable included. Uwell publishes no charge time; UK reviewers measured 25 to 35 minutes.
• Output: up to 18W, no wattage adjustment. The kit picks the power to suit the coil, so there is nothing to set.
• Coils supplied: 1.2Ω and 0.8Ω FeCrAl UN2 Meshed-H. The 1.2Ω coil is fitted; the 0.8Ω is the spare.
• Pod capacity: 2ml (UK TPD limit). Top fill under the mouthpiece cap, with a liquid window on both sides.
• Airflow: wheel on the pod base. Turns from a very tight draw to a loose, restricted lung draw.
• Alerts: LED plus vibration. Green over 60%, blue 30 to 60%, red under 30%; it buzzes on pod insert, charging and faults.

Pick Your Inhale: MTL or RDL on the Uwell Caliburn G2

MTL (mouth to lung) is a cigarette-style draw into the mouth first. RDL (restricted direct lung) is a looser pull straight to the lungs. The coil you fit decides which you get:

• 1.2Ω Caliburn G2 coil, 9 to 13W, MTL. Tightest draw, least vapour, smoothest with 10mg or 20mg nic salts.
• 1.0Ω Caliburn G coil, 10 to 15W, MTL (sold separately). Standard wire, quieter and less vapour.
• 0.8Ω Caliburn G coil, 13 to 18W, loose MTL or RDL. Warmest, most flavour and vapour; best with 5mg to 10mg salts or 3mg to 6mg 50/50.

Close the wheel with the 1.2Ω coil for the tightest draw; open it fully with the 0.8Ω coil for RDL. The 0.8Ω coil stays slightly airy even when closed, so pure MTL vapers should stay on 1.2Ω.

Uwell Caliburn G2 Key Features

• Replaceable coils: swap a £2.49 coil, not a whole pod; the pod lasts months.
• Progressive airflow wheel: fine control over draw tightness, which the Uwell Caliburn A2 does not offer.
• Dual-side liquid window: see the level at a glance, so no dry hits.
• Vibration alerts: a buzz tells you the pod is seated, charging has started or finished, or a fault has tripped.

Coils and E-Liquid Pairing for the Uwell Caliburn G2

All three coils are made for 50/50 or higher-PG liquids. Thick 70/30 shortfills starve the cotton and burn the coil. On the 1.2Ω coil, 10ml nic salts at 10mg or 20mg give a smooth throat hit at low power. On the 0.8Ω coil, drop to 5mg or 10mg salts, or 3mg to 6mg 50/50 freebase, because it delivers more nicotine per puff. Rough guide: under 10 cigarettes a day, 10mg salt; more than that, 20mg salt on the 1.2Ω coil. Browse 10ml nic salt e-liquids for this kit.

Battery, Coil Life and Running Cost

• Battery: most of a working day; heavy users need a half-hour top-up mid-afternoon.
• Coil life: 1 to 2 weeks is typical. Reviewers on Vape Club report menthol and plain fruit lasting up to 3 to 4 weeks, while sweet dessert liquids can finish a coil in under a week.
• Weekly cost: one coil every 10 days from a Uwell Caliburn G and G2 replacement coils 4-pack (£9.95) is about £1.75 a week. Add two 10ml nic salt bottles at 4 for £10 and the week costs roughly £7. A prefilled-pod user getting through a pod a day spends about three times that.

Compatibility and Refills

This is the Uwell Caliburn G2, not the Caliburn G, Caliburn GK2 or Caliburn G3. Pods: only Uwell Caliburn G2 replacement pods (£4.99 for 2) fit. Caliburn G pods, Caliburn A2 pods and Caliburn G3 GPP pods do not fit. Coils: the 0.8Ω and 1.0Ω Uwell Caliburn G coils and the 1.2Ω Uwell Caliburn G2 Coils all fit, and the same coils fit the Uwell Caliburn G, GZ2, GK2, X and Tenet.

How to Set Up the Uwell Caliburn G2

1. Charge with the USB-C cable until the LED turns solid green and the kit buzzes once.
2. Pull the pod off the battery, then pull the mouthpiece cap straight up. It is stiff by design.
3. Push a coil into the pod base with its flat edge lined up to the flat edge of the pod, until it sits flush.
4. Fill through the port on top with a 50/50 or nic salt liquid. Stop below the top of the window.
5. Press the mouthpiece cap back on firmly until it clicks all the way round. A half-seated cap is the number one cause of first-fill leaks.
6. Wait 5 to 10 minutes so the cotton soaks, then click the pod into the battery.
7. Press the fire button 5 times to switch on, set the airflow wheel to taste, and draw.

How to Make the Uwell Caliburn G2 Last Longer

• Stop leaks: keep the kit upright, do not overfill, and close the airflow wheel before it goes in a pocket. Planet of the Vapes reviewers found pods left in the kit for a day could weep through the airflow wheel, so take the pod out if you are putting it down overnight.
• Save the coil: no chain vaping, let the coil cool between draws, and refill before the window runs empty.
• Rebuy early: order coils when you fit your last spare.

Best Colours for the Uwell Caliburn G2

Black is the pick for vapers who carry the kit to work and want it unnoticed; Ash gives the same low-key look in a lighter finish. Pink Gradient is the finish reviewers call Uwell's signature look, for anyone who wants the kit seen. Blue, Green and Red suit households with more than one Caliburn that need telling apart.

Uwell Caliburn G2 Price Comparison

At £18.99 the Uwell Caliburn G2 sits between the Uwell Caliburn A2 Pod Kit at £9.99 and the Uwell Caliburn G3 Pod Kit at £19.99. The running cost is where it wins: a Caliburn G2 coil costs about £2.49 and the pod is reused, while a Caliburn A2 pod (coil built in) costs about £2.75 and a Caliburn G3 GPP pod about £2.50, both binned when the coil dies. Versus the Uwell Caliburn A2, the Caliburn G2 adds a bigger battery, adjustable airflow and replaceable coils for £9 more. See the full Uwell Caliburn range and other refillable pod kits.
