Features

The UWELL Caliburn Koko Prime is built tough with a solid zinc-alloy body that feels nice and premium in the hand. The 690mAh battery easily gets you through a full day of normal vaping, and it charges quickly with the USB-C port.

It comes with two proper mesh coils – the 0.8Ω for richer flavour and decent cloud, and the 1.0Ω for a tighter draw with a stronger throat hit. You get dual airflow control so you can make the draw as tight or loose as you like, perfect for true MTL or a slightly more open restricted direct lung style.

Filling is simple thanks to the easy top-fill system, and the magnetic pod connection is secure and leak-resistant. It works straight out of the box with draw activation just like a disposable vape alternative, but you’ve also got the side button if you prefer manual firing. Overall, it’s a straightforward, reliable little kit that performs well without any complicated menus or settings.

Compatible E-Liquids

The Koko Prime works brilliantly with 50/50 nic salts and high-PG e-liquids. These thinner liquids wick perfectly into the UN2 mesh coils and give you clean, intense flavour with a proper throat hit – ideal if you’re coming from disposable vape alternatives.

It also handles freebase nicotine and even CBD liquids well. While it can manage some 60/40 mixes, it performs best with 50/50 or higher PG ratios. Thick high-VG shortfills (70/30 or above) are not recommended as they can lead to dry hits or slower wicking.

How to Use

Using the UWELL Caliburn Koko Prime is nice and straightforward. Start by taking the pod out of the device. Lift the silicone plug on top and slowly fill it with your 50/50 nic salt e-liquid, making sure not to go over the 2ml max line. If you’re installing a new coil, put 3-4 drops of liquid directly onto the coil holes and let it soak for 5-10 minutes before you start vaping. This helps avoid any dry or burnt hits. Once filled, pop the pod back into the device – it clicks in magnetically.

To vape, simply inhale from the mouthpiece like a normal disposable vape alternatives vape or press the side button to fire it manually. The device will automatically adjust the power for the coil you’re using. Use the dual airflow slider on the side to make the draw tighter (more like a cigarette) or looser for more flavour and vapour. The 690mAh battery usually lasts a full day for most people. When it needs charging, just plug it in with the USB-C cable. Coils normally last between 7 and 14 days, depending on how much you use them – change the coil when the flavour starts to taste flat or burnt. Keep the contacts clean with a dry cloth every few days, and you’ll get the best performance.
