The G4 Pro has an 1800mAh built-in battery and a 2.51-inch touchscreen. Its touchscreen provides access to the device settings and display options.
What it takes is the same as its smaller sibling, and this page sets out the reorder.
The cartridge
GPP, with the coil sealed inside it. There is no separate coil to buy for this device, and nothing on Replacement Coils will fit. The cartridge is the wearing part, and it is on Replacement Pods.
That cartridge is shared with the G3 and G5 families as well as the standard G4, so a spare is portable across UWELL devices rather than tied to this one.
Three modes, and the airflow
Storm, Waves and a Custom mode that shapes the output across the length of the puff. Custom is the interesting one and the reason the touchscreen is as large as it is: shaping a curve is not something a two-button interface handles well.
Airflow is stepless. No clicks, no detents, no numbered positions, which means finding a setting you like and remembering roughly where it was rather than returning to a marked one.
Output is adjustable on screen up to 35W. Follow the fitted cartridge’s marked power guidance and the device instructions.
What to fill it with
Use a suitable 50/50 liquid and choose nicotine concentration according to the exact liquid, cartridge, device and operating-power guidance. Suitable 0.6Ω-and-above stocked pod/MTL configurations are not excluded merely because they are below 1Ω, but this does not approve every concentration at every power. Perceived smoothness or harshness alone does not establish delivered dose. ELFBAR ELFLIQ 10ml and BAR Salts are stocked in 50/50 ranges. The supported GPP power band depends on the fitted resistance.
Use suitable 50/50 liquid with the fitted GPP cartridge and follow the exact cartridge and device guidance. A thicker 70/30 liquid may not wick reliably in this configuration. Freebase and nicotine salt describe nicotine form, not the VG/PG ratio.
Charging and consumables
The G4 Pro charges over USB Type-C. UWELL’s user manual recommends a 5V/2A power adapter and a safety-certified USB cable. Its built-in battery is not user-replaceable; the separate cells on the Batteries page are for devices designed to use them.
The G4 Pro uses integrated-coil cartridges, so a worn or damaged coil requires replacement of the complete cartridge. Assess liquid supply, settings, seals and component condition according to the exact instructions.
Product and variant overview
One device, one cartridge platform. The Caliburn G4 Pro takes GPP cartridges with the coil sealed in, on an 1800mAh cell, with Storm, Waves and Custom output modes.
Compatibility and related products
- Cartridge: Caliburn GPP, coil sealed in. See Replacement Pods.
- No separate coil exists. Nothing on Replacement Coils fits.
- GPP is shared with the G3, G4 and G5 families.
- Internal 1800mAh cell; nothing needed from Batteries.
- Liquid: suitable 50/50 liquid, with concentration selected using the exact liquid, cartridge, device and power guidance.
Buying guidance
- Buy cartridges rather than coils. There is no coil sold separately for this platform.
- Battery capacity: 1800mAh. Time between charges depends on power settings, puff length and frequency. Cartridge capacity is a separate specification.
- Use Custom mode if you want the device to do something the others cannot. Otherwise, the two presets are simpler.
- Stepless airflow means noting where you had it before removing the cartridge.
- For charging, follow UWELL’s manual recommendation of a 5V/2A power adapter and a safety-certified USB cable.
Kenya and Nairobi relevance
Battery capacity alone does not establish a one-day or two-day runtime. Power, puff duration and frequency affect how often charging is needed. Nairobi orders dispatch same-day, with 1–2 business days to the rest of Kenya.
