The Koko is the box-shaped member of the Caliburn family. Choose a supported GPP cartridge and follow the wattage band published for that resistance.
A 1600mAh cell, output to thirty-five watts in one-watt steps, and the same GPP cartridge as the rest of the current family.
The published bands, and why they matter
UWELL give 19 to 35 watts at 0.4 ohms, 13 to 25 at 0.6, 9 to 15 at 0.9 and 6 to 11 at 1.2. Setting a cartridge inside its band is the difference between a coil doing the job it was designed for and one being asked to do something else.
It also tells you what each resistance is for without having to try them. The 1.2 at six to eleven watts is a tight, sparing mouth-to-lung vape; the 0.4 at up to thirty-five is a different device entirely in the same shell.
The cartridge
GPP, coil sealed in, on Replacement Pods. There is no separate coil for this platform, and nothing on Replacement Coils fits it.
Both side-fill and top-fill versions of the GPP run in this device, which is a small convenience worth knowing when you are choosing between listings.
Airflow comes in from the top and adjusts across a range from mouth-to-lung through to a restricted lung draw.
The liquid for each band
The 0.9Ω and 1.2Ω GPP options support tighter, lower-power draws. ELFBAR ELFLIQ 10ml and BAR Salts are 50/50 options; choose the concentration and operating power for the exact cartridge.
GPP cartridges have their own supported operating bands: 0.4Ω at 19–35W, 0.6Ω at 13–25W, 0.9Ω at 9–15W and 1.2Ω at 6–11W. Suitable 50/50 liquid is the stocked pairing for compatible low-power configurations; choose concentration separately.
Suitable 50/50 liquid is the stocked pairing for these GPP configurations. Use thicker liquid only where the exact cartridge and device guidance supports it.
Charging and daily use
Five volts at two amps, with a battery reading from zero to ninety-nine per cent rather than a set of bars. UWELL quote up to six days of use per charge, which is a manufacturer figure and depends entirely on how much you vape.
The coil is integrated into the GPP cartridge, so a worn or damaged coil means replacing the whole cartridge. Check liquid supply and supported settings if performance changes, and stop using a persistently burnt cartridge.
Product and variant overview
One device, one cartridge platform, four resistances with published wattage bands. The G5 Koko takes GPP cartridges in both side-fill and top-fill form, on a 1600mAh cell.
Compatibility and related products
- Cartridge: Caliburn GPP, side-fill or top-fill, coil sealed in. See Replacement Pods.
- No separate coil. Nothing on Replacement Coils fits this device.
- GPP is shared with the G3, G4 and G5 families.
- Internal 1600mAh cell; nothing needed from Batteries.
- Liquid: suitable 50/50 liquid, with concentration selected using the exact liquid, cartridge, device and power guidance.
Buying guidance
- Set the wattage inside the published band for your cartridge. UWELL have done that work, and it is worth using.
- Buy cartridges rather than coils. There is no coil for this platform sold on its own.
- Recheck the liquid’s ratio and nicotine concentration when changing cartridges. Resistance alone does not require a lower concentration; follow the exact cartridge, liquid and device guidance.
- Either fill orientation of the GPP works here, so buy whichever listing suits you.
- Treat the six-day figure as a manufacturer estimate rather than a plan.
Kenya and Nairobi relevance
Use the cartridge’s recommended operating band and the device instructions when setting up. Nairobi orders dispatch the same day; courier delivery elsewhere in Kenya typically takes 1 to 2 business days.
