Uwell Caliburn G4 Pod Kit

The Uwell Caliburn G4 runs on a 1300mAh battery with an OLED screen and 5W to 35W adjustable output. Storm and Waves power modes change the delivery for a stronger hit or a smoother pull. Button fire and auto-draw activation both work on this refillable pod kit. An adjustable airflow slider and reversible pod insert create four draw setups from a single body. For full wattage control in a compact kit with an OLED screen, this is the one.

A 0.4 ohm and 0.9 ohm GPP pod come included with built-in mesh coils and top-fill design. The Caliburn G4 also accepts all G3 pods from the older Caliburn range for extra resistance choices. Five GPP resistances cover 0.4 to 1.2 ohm across both RDL and MTL vaping styles. All pods click in magnetically with no separate coil changes or messy refills.

Nic salt e-liquids pair well with the 0.9 ohm and higher resistance pods at lower wattages. Freebase 50/50 e-liquids suit the 0.4 ohm pod at wider airflow settings for more vapour. Eight colours are available including Sahara Gold, Glacier Blue, and Flamingo Red.

Key Features

1300mAh battery with USB-C charging
OLED screen showing wattage, battery level, and puff counter
5W to 35W adjustable output through button controls
Storm and Waves modes for two different power delivery patterns
Button fire and auto-draw dual activation
GPP and G3 pod compatible from 0.4 to 1.2 ohm
Adjustable airflow slider plus reversible pod for four draw setups
8 colours across the range

Storm Mode and Waves Mode

Storm Mode pushes harder from the start of each draw for a stronger throat hit and more vapour. Waves Mode ramps up gradually for a smoother pull and better battery conservation. Switching between modes uses the button controls on the front of the kit. Storm works well at higher wattages with the 0.4 ohm pod for RDL vaping. Waves pairs better with higher resistance pods at lower wattages for MTL.

Button Controls and Wattage

Action	Button Press
Power on/off	5 clicks
Enter wattage adjustment	3 clicks
Fire	Single press
Lock/unlock	Long press

Once in wattage mode, pressing the button steps through 5W to 35W output. Current wattage, battery level, and puff count appear on the OLED screen at a glance.

GPP and G3 Pod Compatibility

The Caliburn G4 takes the full Caliburn GPP pod range plus older G3 pods.

Pod Type	Resistances	Fill Type	Vaping Style
GPP (G4)	0.4, 0.6, 0.8, 1.0, 1.2 ohm	Top-fill	RDL and MTL
G3	0.4, 0.9 ohm	Top-fill / Side-fill	RDL and MTL

All pods click straight in with built-in mesh coils and no separate coil swaps needed. Lower resistance pods at 0.4 ohm and 0.6 ohm suit RDL vaping with the airflow open. Higher resistance pods at 0.8 ohm and above suit MTL with the airflow tightened up.

Airflow and Reversible Pod

A side-mounted airflow slider controls draw tightness across the full resistance range. Flipping the pod around in the kit changes the airflow path for a second configuration. Combining both settings provides four airflow setups from tight MTL through to open RDL.

Colour Options

Eight colours in the range:

Twilight Silver
Gunmetal Grey
Sahara Gold
Seashell White
Glacier Blue
Flamingo Red
Polar Black
Karst Grey

All versions have a transparent top section for checking the e-liquid level through the pod.

Why Choose the Caliburn G4

For vapers moving from prefilled pods or a basic kit, the G4 delivers full wattage control. Adjustable output, two power modes, and four airflow configurations all come in a pocket-sized body. Auto-draw activation means the kit still fires from a simple inhale without touching the button.

GPP pods range from tight MTL to wide open RDL across five resistance options. Starting on the 0.9 ohm pod for a tighter draw and moving to 0.4 ohm later needs no upgrades. One kit handles both vaping styles across the full resistance range without changes.

What's the difference between Storm and Waves mode on the Caliburn G4?

Storm hits harder from the first second of your draw. More vapour, stronger throat hits. Waves build up slowly for a gentler pull. Try Storm with the 0.4Ω pod and Waves with 0.8Ω or above.

Does the Caliburn G4 take G3 pods?

Yes. Both GPP and G3 pods fit the Caliburn G4. If you've got G3 pods left over from an older Caliburn kit they'll work fine.

When did the Caliburn G4 come out?

Mid 2024. The G4 Pro came along about a year later with a touchscreen and bigger battery, but the standard G4 is still in the lineup.

How do you fill the Caliburn G4 pods?

Pop the pod out, open the rubber cap on top, and fill it up. Give it two minutes before you vape so the cotton inside the coil has time to soak through.

What's the difference between the Caliburn G4 and G4 Pro?

Bigger battery (1800mAh vs 1300mAh), full colour touchscreen instead of the OLED, and you get custom power curves and themes on the Pro. Same GPP pods on both though, so your pods carry over if you upgrade.

Is the Caliburn G4 MTL or RDL?

Both. Tighten the airflow and use 0.8Ω or higher for MTL. Open it up with the 0.4Ω pod for RDL. Flipping the pod around gives you extra airflow options too.
