Uwell Caliburn G4 Classic Key Features

Dual activation

Fire it by inhaling or by pressing the button. SourceMore lists twin smart vaping sensors for the draw activation.

Dual airflow control

Two airflow adjustments let you tune the draw more precisely, from mouth-to-lung (MTL) to a looser restricted direct-lung (RDL) feel.

Ambient lighting and oil window

Dynamic ambient lighting adds style, and a clear view window shows the e-liquid level.

U² anti-leak

SourceMore lists Uwell’s U² anti-leak technology.

Which Cartridges Fit the Caliburn G4 Classic?

The Caliburn G4 Classic uses Caliburn GPP cartridges.

We stock the Uwell Caliburn GPP 3ml pod cartridge in 0.4Ω, 0.6Ω, 0.9Ω and 1.2Ω mesh. The coil is built into each cartridge, so you replace the whole cartridge when the flavour fades. Use 0.9–1.2Ω for a tight mouth-to-lung (MTL) draw with nicotine salts, and 0.4–0.6Ω for a looser, warmer restricted direct-lung (RDL) draw. Prime each new cartridge: fill it through the side port and wait about five minutes before vaping.

How to Use the Uwell Caliburn G4 Classic

Charge the device fully before first use.
Fill the cartridge through the side port, leaving a little space.
Insert the cartridge and wait about five minutes for the coil to soak.
Choose a mode and set the airflow, starting gently.
Inhale to vape and adjust until the draw feels right.

Best E-Liquid for the Caliburn G4 Classic

With the included 0.4Ω and 0.6Ω cartridges, a lower nicotine strength is more comfortable, because the looser draw delivers more vapour per puff. For nicotine salts at higher strengths, use a 0.9Ω or 1.2Ω GPP cartridge. Browse our UAE e-liquids.

Troubleshooting

Burnt taste: the cartridge was not soaked long enough, or it ran dry. A burnt coil cannot be recovered, so fit a new cartridge and wait about five minutes after filling.
No vapour when drawing: check the battery, make sure the cartridge is seated firmly, and wipe the contacts dry.
Gurgling or e-liquid in the mouthpiece: the cartridge may be overfilled or the device was left in the heat. Remove the cartridge, blow gently through the mouthpiece, and store the device upright.
Leaking: check the fill port is closed firmly and that the cartridge has no cracks.

Care Tips for the UAE Climate

Heat is hard on pod kits. Do not leave the device in a parked car or in direct sun: high temperatures thin e-liquid, which can make cartridges leak, and they are bad for lithium batteries. Wipe the cartridge contacts now and then with a dry tissue, and charge with a standard 5V charger.

UAE Rules for the Caliburn G4 Classic

The Caliburn G4 Classic is sold empty, with no e-liquid or nicotine included, so the rules apply to what you fill it with.

From 1 September 2026, a minimum excise price of AED 1 per mL also applies to e-liquid. Sale is restricted to adults 21 and over. See our guide to vaping laws in Dubai and the UAE.
