Review Summary
The Uwell Caliburn G5 KOKO is the strongest iteration of the compact KOKO format to date. Dual Waves and Storm modes give meaningful output flexibility within a device that remains genuinely pocketable, the Starlit Ocean Display adds visual personality without complicating the interface, and PRO-FOCS 4.0 pod performance is consistently strong across the included 0.6Ω GPP pod and the broader GPP range. The 1600mAh battery handles a full day of regular use comfortably, and compatibility with both GPP and G3 pods gives long-term coil flexibility that earlier KOKO devices could not match. A well-rounded, feature-led compact pod kit that earns its place at the top of the KOKO range.
The Uwell Caliburn G5 Koko Pod Kit is a Uwell pod kit designed for MTL & RDL vaping , powered by a 1600mAh battery with a 2ml e-liquid capacity and USB C charging , available in 6 colours.

The G5 KOKO keeps the compact square KOKO form factor at 84.8 x 49.1 x 21.8mm that the range is known for, and the frosted shell finish gives it a clean, understated appearance that sits comfortably alongside both professional and casual everyday carry. The six colour options — Ocean Flame, Fantasy Pink, Midnight Blue, Golden Brown, Mocha Silver, and Onyx Black — all carry a leather-touch finish returning from the GK2 that adds a premium tactile quality and improves grip during longer sessions. All six hold up well against pocket wear and the surface contact that marks cheaper finishes quickly.
The Starlit Ocean Display is the most visually distinctive element the KOKO range has carried to date. Animated marine animal light effects sync with each draw and change with the current mode, while battery percentage and current mode information remain clearly visible at all times. For vapers who prefer a more discreet experience, four clicks on the fire button toggles the light effects off without removing the practical battery and mode display. The display is bright enough to read clearly in most lighting conditions without needing to angle the device.
The button controls are logical and well-positioned. One click fires, two clicks switches between Waves and Storm mode, three clicks adjusts output wattage within the selected mode, four clicks toggles the light effects, and five clicks powers the device on or off. The top airflow slider moves smoothly and holds its position reliably once set, and the reversible pod orientation gives a second airflow path per resistance without requiring any additional hardware or accessories.
The GPP pods seat firmly with U2 anti-leak construction and a top-fill design that keeps refilling clean without removing the pod from the device. The overall build confidence of the G5 KOKO is high for the price point, and the frosted shell chassis feels durable without adding unnecessary weight to a device designed for all-day compact carry. All products stocked at WizVape comply fully with UK TPD regulations, and the G5 KOKO ships with a 2ml TPD-compliant pod as standard.
The dual Waves and Storm modes are the performance feature that most distinguishes the G5 KOKO from previous KOKO devices. Waves delivers smooth, consistent wattage throughout each inhale, keeping output steady for longer draws and flavour consistency across extended sessions. Storm ramps power up during the draw for a stronger throat hit and denser vapour production, which suits shorter, more direct puffs and vapers who prefer a more impactful inhale. Switching between the two takes two clicks of the fire button and is reflected immediately on the display, making it a quick and habitual adjustment rather than a menu-navigation task.
PRO-FOCS 4.0 flavour technology drives consistent performance across the full GPP resistance range. The included 0.6Ω GPP pod delivers a balanced restricted RDL draw that works well with both nicotine salt e-liquids at lower strengths and 50/50 freebase e-liquids, and the built-in mesh coil heats quickly and evenly for consistent flavour from the first draw. The U2 anti-leak construction in the pod housing keeps the draw clean and the device body dry in daily carry, and the top-fill design means refilling does not require removing the pod from the device.
The full Caliburn GPP pod range extends the G5 KOKO's draw flexibility considerably beyond the included 0.6Ω. The 0.4Ω at 25W to 30W opens the draw into RDL territory, the 0.9Ω at 12W to 16W tightens it into a controlled MTL pull, and the 1.2Ω at 10W to 13W gives the tightest, most cigarette-like draw in the range. Compatibility with earlier Caliburn G3 pods in 0.4Ω, 0.6Ω, 0.8Ω, and 1.0Ω adds further flexibility for vapers already within the Caliburn ecosystem. The top airflow slider and reversible pod orientation give additional draw resistance adjustment independently of pod resistance and wattage, allowing fine-tuning beyond what most compact pod kits offer.
The 1600mAh battery comfortably covers a full day of regular MTL and RDL vaping for most vapers across both Waves and Storm modes. Waves mode is the more battery-efficient of the two, delivering consistent output without the power ramp-up of Storm mode, making it the sensible default for all-day carry where endurance matters more than maximum performance. Storm mode draws more power per draw and will reduce runtime for heavier users, though for moderate vapers the difference between the two modes in daily battery consumption is manageable.
USB-C charging brings the 1600mAh battery back to full quickly, and the Starlit Ocean Display shows exact battery percentage at all times so you always know where you stand without estimating from a basic LED indicator. For vapers who want a larger battery in a compact pod kit without stepping up in chassis size, the G5 KOKO's 1600mAh at this form factor is among the more capable options available in the compact square pod kit bracket. Pairing the G5 KOKO with a selection of compatible pods and e-liquids through a vape kit bundle is worth considering for a complete setup from a single purchase.
The G5 KOKO is straightforward to get started with. Fill the pod through the top-fill port, prime for five to ten minutes, insert the pod, and the device is ready to use. Both button-fire and draw-activated operation are built in, so vapers coming from auto-draw devices and those who prefer a fire button are both accommodated without any setup or configuration required. Five clicks powers the device on, and the button control layout covers mode switching, wattage adjustment, and light effect toggling through a logical click sequence that becomes second nature within a session.
Switching between Waves and Storm mode takes two clicks and is confirmed immediately on the display, and adjusting output wattage within the selected mode takes three clicks to enter the adjustment sequence. The top airflow slider is immediately intuitive, and the reversible pod orientation takes a moment to understand but adds a genuinely useful additional draw configuration once familiar. Changing Uwell Caliburn pods is clean and tool-free — remove the pod, fit a new one, fill, prime, and the device is ready within minutes.
For vapers transitioning from cigarettes or disposable vapes, the draw-activated operation and top-fill pod system make the G5 KOKO as accessible as any refillable pod kit at this price point. The dual mode system adds a short adjustment period for those coming from single-output devices, but the practical difference between Waves and Storm is clear enough that most vapers settle on a preferred mode quickly and rarely revisit the choice day to day.
The Uwell Caliburn G5 KOKO is built for vapers who want a compact, pocketable pod kit with more output control and visual personality than a basic single-mode device provides. The dual Waves and Storm modes, Starlit Ocean Display, and broad GPP and G3 pod compatibility make it the most feature-complete KOKO device Uwell has produced, and it suits vapers who want that depth of control within the compact square KOKO chassis specifically.
For vapers transitioning from cigarettes or disposable vapes, the G5 KOKO is approachable enough to work well as a first refillable pod kit. Draw-activated operation removes the need to locate a fire button, Smart Mode sets an appropriate output automatically, and the included 0.6Ω pod with a nicotine salt or 50/50 e-liquid is a natural starting point that works well without requiring any adjustment. The running costs of a refillable kit are considerably lower than staying on disposables long term, and the full GPP pod range gives draw flexibility to explore as confidence grows.
Experienced vapers already within the Caliburn ecosystem will find the G5 KOKO a natural step forward from earlier KOKO devices, with the GPP and G3 pod compatibility meaning existing pods carry across without any compatibility concerns. For a broader look at what Uwell offers across their lineup, the complete Uwell range and full Uwell vape kit range are worth exploring alongside the G5 KOKO.
It is not suited to high-power DTL vaping beyond 35W, and vapers who prefer a taller, slimmer pen-style chassis will find better options in the broader vape kit range. On price, the G5 KOKO represents strong value for the feature set it delivers within the compact pod kit bracket. Browsing current vape deals before purchasing is always worth doing, and the full range of compatible Uwell coils and pods is stocked alongside the kit at WizVape.

Yes. The Uwell Caliburn G5 KOKO is suitable for beginners despite offering more output control than a basic single-mode pod kit. Draw-activated operation means there is no fire button to locate, the top-fill pod system is straightforward to refill, and the included 0.6Ω GPP pod with a nicotine salt or 50/50 e-liquid is a natural starting point that works well without any adjustment initially. The dual Waves and Storm modes add a short learning curve, but the practical difference between the two is clear enough that most vapers settle on a preferred mode quickly.
The Uwell Caliburn G5 KOKO is compatible with the full Caliburn GPP pod platform in 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω, as well as earlier Caliburn G3 pods in 0.4Ω, 0.6Ω, 0.8Ω, and 1.0Ω. All GPP pods feature built-in mesh coils, U2 anti-leak construction, and a top-fill design. The kit ships with a 0.6Ω GPP pod included. All pods hold 2ml of e-liquid in line with UK TPD regulations.
Waves mode delivers smooth, consistent wattage throughout each inhale, keeping output steady for longer draws, flavour consistency, and better battery efficiency. Storm mode ramps power up during the draw for a stronger throat hit and denser vapour production, which suits shorter, more direct puffs and vapers who prefer a more impactful inhale. Switching between the two takes two clicks of the fire button and is confirmed immediately on the Starlit Ocean Display.
PRO-FOCS 4.0 is Uwell's flavour optimisation technology built into the G5 KOKO chipset and GPP pod platform. It delivers consistent flavour performance across all GPP pod resistances from 0.4Ω through to 1.2Ω, with even coil heating and stable output that maintains flavour quality across the full lifespan of each pod. PRO-FOCS 4.0 is the latest iteration of the technology platform Uwell uses across the Caliburn range.
For the 0.9Ω and 1.2Ω MTL pods, nicotine salt e-liquids at 10mg or 20mg in a 50/50 VG/PG ratio work best. For the 0.6Ω pod, both nicotine salts at lower strengths and 50/50 freebase e-liquids work well. For the 0.4Ω RDL pod at higher wattage, 50/50 freebase e-liquids or lower-strength nicotine salts are the most appropriate choice. High-VG blends of 70/30 or above are not recommended for tighter MTL pods as the thicker consistency can restrict wicking at lower wattages and cause dry hits.
The 1600mAh battery in the Uwell Caliburn G5 KOKO comfortably covers a full day of regular MTL and RDL vaping for most vapers. Waves mode is the more battery-efficient of the two modes, making it the sensible default for all-day carry. Storm mode draws more power per draw and will reduce runtime for heavier users. The Starlit Ocean Display shows exact battery percentage at all times so you always know precisely how much charge remains.
Yes. The Uwell Caliburn G5 KOKO supports both draw-activated and button-fire operation. Draw-activated vaping fires the device automatically the moment you inhale without pressing any button. Button fire is also available for vapers who prefer manual activation. Both activation methods work across Waves and Storm modes without any configuration required.
The reversible pod orientation on the Uwell Caliburn G5 KOKO allows the GPP pod to be inserted in two directions, each providing a different airflow path through the device. Combined with the top airflow slider, this gives two distinct airflow configurations per pod resistance without requiring any additional hardware or accessories. It is a practical feature that adds draw resistance flexibility beyond what the airflow slider alone provides.
On moderate use with a mid-range nicotine salt, a Caliburn GPP pod in the G5 KOKO typically lasts one to two weeks before any noticeable drop in flavour quality. PRO-FOCS 4.0 technology and the built-in mesh coil construction help maintain consistent flavour further into each pod's lifespan. Heavily sweetened e-liquids and heavier use in Storm mode at higher wattages will shorten pod life. Priming a new pod for five to ten minutes before the first draw is important to avoid dry hits from the outset.
The Uwell Caliburn G5 KOKO is the first KOKO device to feature dual Waves and Storm vaping modes, giving output flexibility that earlier KOKO models did not offer. The Starlit Ocean Display with animated marine light effects is a significant step forward from the basic screens on the G3 Pro KOKO, and the 1600mAh battery at 35W output improves on earlier models in both capacity and maximum wattage. GPP and G3 pod compatibility means existing Caliburn users can carry their current pods across without any compatibility concerns.
Press the fire button twice to switch between Waves and Storm mode on the Uwell Caliburn G5 KOKO. The Starlit Ocean Display confirms the active mode immediately after switching. Three clicks of the fire button enters the wattage adjustment sequence to modify output within whichever mode is currently selected. Four clicks toggles the animated light effects on or off, and five clicks powers the device on or off.
The Uwell Caliburn G5 KOKO Pod Kit is available from WizVape with UK stock held and ready to dispatch. WizVape also stocks the full range of compatible Caliburn GPP and G3 pods alongside the kit, covering all available resistances from 0.4Ω through to 1.2Ω.
