Uwell Caliburn KOKO Pod Kit

Introduction

The Uwell Caliburn KOKO is the square, palm-sized version of the original Uwell Caliburn: a refillable MTL pod kit with no buttons, a 520mAh battery and a fixed 11W output, currently £8.99. MTL means mouth-to-lung, a tight draw taken like a cigarette. It suits adult smokers and vapers who want the smallest kit that still refills. It is not for anyone who needs USB-C charging or a full day of heavy use from one charge.

What the Uwell Caliburn KOKO Fixes: A Refillable Kit That Vanishes in a Pocket

The whole kit measures 67 x 43 x 12mm, about the footprint of a matchbox, in an aluminium alloy shell. A chain lanyard comes in the box for wearing it around the neck. There is nothing to switch on: inhale, and it fires.

The trade-off is age. This is an older design, so charging is by Micro-USB, and the port sits on the base. The Planet of the Vapes reviewer listed both as the only drawbacks, because the kit cannot stand upright while it charges. Lay it flat, and that problem goes away.

This is the original Uwell Caliburn KOKO, not the Uwell Caliburn KOKO Prime or the newer Uwell Caliburn G3 and G4 KOKO kits, which all take different pods.

Which Pods Fit: 1.2Ω Uwell Caliburn KOKO Pods and 1.4Ω Uwell Caliburn Pods

Two pods fit, and both hold 2ml with the coil (the heating part) built in. Ω, or ohm, is the coil's resistance.

• Uwell Caliburn KOKO pod, 1.2Ω: the pod supplied with the kit. Lower resistance draws a little more power, so the puff is slightly warmer.
• Original Uwell Caliburn pod, 1.4Ω: also fits. Slightly cooler and a touch easier on the battery.
• Does not fit: Uwell Caliburn G, G2 and G3 pods. Those belong to the newer kits listed below.

Spare Uwell Caliburn pods come in packs of four. When flavour fades, the whole pod is swapped; there is no separate coil to change.

Which Uwell Caliburn KOKO Should You Buy?

• Uwell Caliburn KOKO (this kit): the slimmest and simplest. 520mAh, fixed 11W, sealed-coil pods.
• Uwell Caliburn KOKO Prime: 690mAh, 15W, USB-C and replaceable Uwell Caliburn G coils. Versus the Uwell Caliburn KOKO Prime, the Uwell Caliburn KOKO is slimmer (12mm against 16mm) but has the smaller battery and the older charging port.
• Uwell Caliburn G3 Lite KOKO: a much larger 1200mAh battery with 0.6Ω Uwell Caliburn G3 pods for a looser draw.
• Uwell Caliburn G3 Pro KOKO: adds a screen, a fire button and both MTL and RDL pods. RDL is a looser, airier draw.
• Uwell Caliburn G4 Pro KOKO: the top of the range, with a 2000mAh battery, up to 35W and a touchscreen.

Outside Uwell, the Aspire Gotek X is a pen-shaped option at a similar budget, and the OXVA Xlim Pro 3 is the step up for vapers who want more power and settings.

E-Liquid That Suits an 11W Pod

Thin e-liquid works best. Choose 50/50, meaning half PG and half VG (the two base liquids), or a higher-PG mix. Nic salts, a smoother type of nicotine, are the natural match at this low power: 20mg for a heavier smoking habit, 10mg for a lighter one. Thick 70% VG shortfills soak in too slowly for these small coils. The 10ml nic salts and e-liquids range has every strength.

Filling the Top-Fill Pod, Step by Step

1. Lift the pod out of the device. A clip and two magnets hold it.
2. Pull the black mouthpiece cap off the top of the pod.
3. Fill through one of the two ports under the cap, leaving a small air gap.
4. Press the cap back on until it clicks.
5. Stand a new pod for about ten minutes so the cotton soaks.
6. Drop the pod back in and inhale.

Battery, Pod Life and Running Cost

A 520mAh battery at 11W covers a light to moderate day; heavy users should expect an afternoon top-up. Uwell's listed specs give no charge time. The LED shows battery level while vaping and charging. On pod life, the Planet of the Vapes review rated it excellent and noted the pods are easy to find in the UK. As a guide, one to two weeks per pod is typical on 50/50 e-liquid. A 10ml bottle fills the 2ml pod five times, which keeps the weekly cost to a bottle or two and a share of a pod pack.

Habits That Stretch Pod and Battery Life

• Keep it topped up. Running the pod near empty scorches the cotton.
• Pause between puffs. The kit cuts off after 10 seconds, but chain puffing still dries the coil.
• Avoid very sweet e-liquids. They coat the coil and dull the flavour early.
• Dry the pod bay. Wipe away condensation under the pod so the contacts stay clean.
• Charge lying flat. The port is on the base, so never prop it on the cable.

Black, Blue, Red or Silver?

All four colours share the same metal shell, so the choice is about how visible the kit should be. Black is the low-key pick for a jacket pocket. Silver has a plain, tool-like look and shows scratches least on bare metal edges. Blue and Red are easier to find in a bag and suit anyone wearing the kit on the lanyard.
