Uwell Caliburn G4 Pod Kit

The Uwell Caliburn G4 has a 1300mAh battery with an OLED screen and 5W to 35W adjustable output. Storm and Waves power modes change the output 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.

A 0.4 ohm and 0.9 ohm GPP pod come included with mesh vape coils and a top-fill design. The Caliburn G4 also accepts all G3 pods from the older Caliburn range for extra resistance choices. Four 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, and the vape juice flavours for the Caliburn G4 guide covers pairings for each pod. Eight colours are available including Sahara Gold, Glacier Blue, and Flamingo Red.

Caliburn G4 Storm Mode vs 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. In short, the Waves vs Storm difference is a smoother ramp against a harder initial hit.

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, with replacements in the full Caliburn pods range.

Pod Type	Resistances	Fill Type	Vaping Style
GPP (G4)	0.4, 0.6, 0.9, 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 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 0.9 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.
