UWELL Caliburn AK2 Vape Review: Better Than KOKO?

Build And Design
You find the most similarities with the original KOKO, as UWELL seems to have taken a U-turn in terms of design. The Caliburn Ak2 is rectangular with rounded sides and flat on both the front and back of the device.
The pod is located at the top right of the device with a cutout section on the top left, so you can attach a lanyard to carry around your device. The Caliburn Ak2 is almost identical in appearance and size to the original Caliburn KOKO.

The AK2 Features
There are plenty of valuable features that the Caliburn Ak2 exhibit that makes the device a step above the previous KOKO pod kits.
The Top Features
Portability
The AK2 is an extremely slim line and light pod device which is easily transported and pocket friendly.
Design And Appearance
The design of the pod device is sturdy but stylish, with colours available to suit everyone's taste. The aluminium alloy casing creates a device that is easy to keep and hard to damage and provides a smooth metallic finish.
Caliburn has also collaborated with CyberPunk to create 2 new cool designs for the AK2.
E-Liquid Viewing Window
This is a super handy feature located at the top on one side of the device, allowing you to see through to the pod and asses the E-liquid level left inside the pod without having to remove the pod to check as you do with other Caliburn pod kits. This will save you from letting your juice level fall too low and prematurely burning your coil.
Anti Leak Technology
Caliburn has really focused on making sure this device is anti-leak. The pod fill port is located at the top of the cartridge once the mouthpiece is removed; the pod is connected to the device using magnetics, keeping it in place, reducing the chances of leaking, and allowing it to be mess-free.
Auto Draw Mode
There is no fire button on the Caliburn ak2, meaning your only option is to use auto draw; this creates a straightforward, convenient vaping experience.
Ex-Smoker Friendly
This device is fantastic for people transitioning from cigarettes to beginner vapers. Because of its pre-installed coil, simple setting, comfortable mouthpiece, auto draw activated inhale and fixed power output; you'll find this vape offers the necessary satisfaction.
Battery Life
The internal battery of the AK2 is 520 mAh; you can expect this to easily last a full day, averaging around 2.5 ml per full charge. The fast charging ability delivered through a USB type c port allows you to reach about 90% charge in 35 minutes. This creates a super convenient vape.
An LED indicator tells the device's battery level via a colour-coded light.
Green LED: 60-100%
Blue LED: 30-60%
Red LED: 0-30%
Pod Review
The Caliburn AK2 uses the same pods as the Caliburn A2; the pods come pre-installed with a 0.9Ω coil. These coils can not be changed or removed from the pods.
The pod will need to be replaced once the coil begins to burn out; removing the pod and installing a new one is extremely easy; you just pull the pod out and slot it back in; magnets hold it in the device.
To fill your pod with e-liquid, you simply remove the mouthpiece, which also acts as a cap to the pod; the pod is top filling, so you squeeze the juice into the two holes at the very top of the pod on either side until you reach the line.
Make sure to then leave the pod to sit upright for around 10 minutes to the liquid soak the wick; this will only need to be done once with every new pod.
Once you experience any burnt taste, you will need to replace the pod; once you are used to this kit, you'll pick up on signs that your pods need replacing before any unpleasant tastes are experienced.
You can expect each coil to last around 20ml, which would be around 10 uses.
