An update on Uwell’s much loved original Caliburn kit, the Caliburn KOKO Prime is a compact, boxy little pod kit for both mouth to lung and direct to lung vapers. Constructed from light-weight and durable aluminium alloy and PCTG materials, it’s a hard wearing kit. Inside, it’s powered by a built-in 650mAh battery which can fire at up to 15 watts. There’s an LED light to let you know how much battery you have remaining, fading from green to red as the battery drains. When you need to recharge, plug in with the included Type-C cable. 1.6amp charging capability will have your kit back up to full power in less than an hour. There are no buttons to worry about, to use the Caliburn KOKO Prime, you just inhale on the mouthpiece to vape. If you want to adjust your airflow, simply rotate the pod in place to tighten or loosen your inhale.

The pod itself can hold 2ml of e-liquid and features replaceable coils. It’s compatible with the Uwell G coil range, giving you a selection of resistance levels to choose from. You’ll get two coils in the kit to get you started. The 1.0ohm is ideal to use with nic salts and 50:50 e-liquids, giving you a tight mouth to lung inhale. Your other option is the 0.8ohm, which can be used with higher VG e-liquids and will give you a restricted direct to lung inhale. The KOKO Prime will adjust its wattage according to your coil, slowly dropping in power as the battery drains.
