The Story
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.

GPP and G3 Pod Compatibility
The Caliburn G4 takes the full Caliburn GPP pod range plus older G3 pods.
Pod Type |

GPP (G4) |

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.
