Uwell Caliburn Koko Review: Better than the Caliburn?

Author: Alisa Yin / Category: Review / Published: Mar-19-2020

The Caliburn Koko is the first pod system from the Uwell, which is also a simplified version of the very popular Caliburn pod mod kit. The Caliburn Koko uses the aluminum alloy construction and matte finish for extra durability. It is small and has an ultra-thin body, which is convenient to take anywhere. The square-shaped design and lightweight frame make it elegant and portable. Driven by 520mAh built-in battery, the Uwell Caliburn Koko can fire up to 11W and is draw-activated without any button. The small LED indicator shows battery life. The 2ml pod cartridge with 1.2ohm, round-wire coil brings you the looser MTL vape. The Koko can also use the 1.4ohm Caliburn pods.

Build Quality and Design of Uwell Caliburn Koko

The Uwell Caliburn Koko is a tiny and square-shaped pod device. It measures at 67mm x 43mm x 12mm and weighs only 33g, which is ultra-portable and pocket-friendly. The Koko has a lightweight aluminum alloy chassis with a durable plastic cartridge. It uses the minimalist design without any button. The integrated mouthpiece allows you to start inhaling directly. The lanyard in the box allows you to wear the stylish Koko around your neck.

The Uwell Caliburn Koko is well-crafted and has an excellent build quality. The machining is smooth and sleek. The branding ‘Koko’ is imprinted on both sides. There are two gold-plated contacts and two magnets covered by plastic and a small airflow valve inside the top of the device. The LED light and a small airflow hole sit on one side of the device. The bottom of the device has a micro USB charging port and three battery vent holes. There is an opening on the top to attach the lanyard.

The Uwell Caliburn Koko kit comes with two plastic cartridges, one of which is already pre-installed into the device. The 1.2ohm pod has a red base and the 1.4ohm pod has a black base. The black plastic mouthpiece is removable. There are two small filling ports to either side of the chamber.

The Uwell Caliburn Koko utilizes the same 520mAh battery as the Caliburn, which can last for an entire day with moderate use. It supports a maximum output of 11W and the voltage range goes from 3.2V to 4.0V. The advanced Bein chip offers multiple safety features such as ten-second cut-off time, short-circuit protection, etc. The LED indicator shows the battery level - green for high, blue for medium, red for low. When the vape juice drains out, the LED light will flash the red light.

The Caliburn Koko features the buttonless design. You will only need to take a draw directly to create vapor.

Uwell Caliburn Koko Pod Cartridge

The Uwell Caliburn Koko Pod holds 2ml e-liquid and comes with fixed coils. It has the top filling design for easy refilling without leaking. You will need to remove the black integrated mouthpiece to reveal the filling port. The Koko kit comes with two cartridges, a 1.2ohm pre-installed (red base) pod and a 1.4ohm spare pod (black base) both of the pods are great to use the regular vape juice and nic salt.

How to Fill the Pod:

  • Remove the mouthpiece from the pod
  • Fill your favorite e-liquid through one of the filling holes
  • Place back the mouthpiece onto the pod
  • Wait at least 5min to get the coil fully saturated
  • Place the pod onto the device and take a draw

Uwell Caliburn Koko Pod Kit Review

The Uwell Caliburn Koko is a small and exquisite device that provides a warmer draw. Made of lightweight aluminum alloy with small size, the Caliburn Koko is ultra-portable, easy to take anywhere. The 520mAh built-in battery can be used for an entire day on a full charge. Although the wattage output is only 11W, the Koko can bring you excellent flavor with decent vapor. The airflow slots allow you to enjoy the looser MTL vape experience. The pod comes with fixed coils rather than replaceable coils, which is a waste of materials. If you already have a Caliburn, I will not suggest you pick up the Koko as they don’t have many differences. If you are looking for a portable and stealthy vape device, the Uwell Caliburn Koko will hit the spot.
