Aside from the draw, the two devices perform identically. Same battery life, same flavor output, and same ease of use. The AK2 is actually a little easier to use than the A2 because it does not have any buttons, but this also means there’s no button activated firing. That shouldn’t be an issue though because the draw activated firing on the AK2 is fine-tuned and works remarkably well. So far I've tried the original Uwell Koko, the Uwell AK2, the Uwell GK2 and now I'm using the Uwell Caliburn AK3. Filling. It’s as simple as the original. Just snap off the mouthpiece, and fill using the red silicone fill port. Too easy. Please note: the Caliburn AK2 Pod System can not be used with the original Caliburn pods or Caliburn G pods.

Lithium Ion batteries are safely used in millions of devices around the world, every day. As with most high energy devices, there are various risks that users should be aware of when using them. Batteries can pose a fire risk when, over-charged, short-circuited, submerged in water or if their casing is damaged. Although many Lithium Ion batteries are protected, therefore it is vital that you still take the following precautions, as the protection circuit is a potential safety mechanism as opposed to something that should be relied upon.

How can I avoid damaging a battery

Operating is simple – you just inhale on the mouthpiece to fire, no buttons or adjustments to contend with! As this kit is inhale activated, there are no buttons or menus for you to navigate. Instead, all you have to do is inhale on the mouthpiece to start vaping. Designed to deliver a vape that feels closer to a cigarette, this kit creates a smaller amount of vapour for an MTL inhale. The fixed power output of this kit also ensures you’ll experience a consistent vape every time – even when the device is low on battery. Please Uwell increase the battery capacity and add an easier fill port and this could have easily been scoring in the 9’s and 10’s! The UWELL Caliburn AK2 is a suave pod system designed and optimised for a satisfying vape. This device works perfectly with a range of e-liquid types, including nicotine salts and freebase liquids. A generous 520mAh battery provides several hours of use between charges and can be topped up to 90% in only 35 minutes due to speedy USB-C technology. This uses exactly the same pods – and I am even continuing using the pod I used in the A2 kit – to get a good idea of coil life.

This is quite similar to the AK2 (sadly I no longer own any of these – gave them all away) but does have a more ergonomic appearance. AK2 มาพร้อมกับความจุของแบตเตอรี่ 520 mAh ซึ่งเพียงพอต่อการใช้งานในหนึ่งวันเพราะคอยล์ใช้ไฟน้อย อีกทั้งตัวเครื่องใช้กำลังไฟ Out-Put เพียงแค่ 15 วัตต์ เปรียบได้กับการเติมน้ำยาประมาณ 2-3 แทงค์ก่อนที่แบตเตอรี่จะหมด The Uwell Caliburn AK3 pod vape kit is a compact matchbox-style option. Easy to use, it produces a discreet amount of vapour for an MTL (Mouth To Lung) vape. Powered by a built-in 520mAh battery, you can vape for longer on just a single charge and the kit will reach full charge in just 15 minutes, thanks to USB-C fast charging. It’s a good option for beginners or seasoned vapers after a simpler vape and each kit includes two 1.0 Ohm Caliburn A3 pods to help you get started.

Plus, the built-in coil design means you don’t have to worry about messy coil changes, you can just replace the entire pod. Never use a battery that has been clearly damaged or is leaking. It should be discarded immediately in an appropriate way.Most importantly, the refillable and replaceable pod is magnetically attached to the device and features a leak-proof top filling system while accommodating 2 ml of either nicotine salts or freebase E-Juice. The dual firing system allows users to either fire the device via the firing button or the draw-activated firing system. In addition, the Caliburn AK2 kit features a rapid charge Type-C USB port, drastically reducing the time need to re-charge. Conclusion : The Uwell Caliburn AK2 is an updated version of Uwell's most popular pods kits, the Caliburn Koko and Caliburn KOKO prime pod kits. Each kit comes with two Caliburn A2 refillable pods to help you get started, making it an excellent alternative for beginning vapers or anybody searching for a simpler vape. Uwell has maintained a higher degree of vapour quality and flavour due to its technology. The PRO FOCS technology significantly improves the vaping experience over most of its competitors. The mouthpiece is unquestionably the most comfortable yet.

Battery indicator = this changes colour according to the battery charge remaining whilst vaping – Green LED = over 60% charge, Blue LED = 30-60% and Red LED = less than 30%. Note that if on the “animated LED” setting after vaping it will show battery charge colour and then cycle through other colours.

Design-wise, the new Koko has a nice satin/matt metallic coating, that is smooth, but not completely, giving you a little grip, and making sure your fingerprints don’t ruin the finish while using it. Wrapped around the main panel are diagonal stripes polished to a gloss, with the word “Caliburn” emblazoned over the top. It’s interesting that Uwell have used that on here, considering most refer to these devices as “Koko”. Perhaps they are trying to emphasise that this is in fact a Caliburn just another form factor in the same range. This still has the horrible snap off mouthpiece to access the filling port. It is really hard for me to get this off. Uwell ได้ทำการออกแบบหัวCaliburn AK2 ใหม่ให้เหมาะกับริมฝีปากสำหรับคนสูบบุหรี่ไฟฟ้ามาโดยเฉพาะ โดยในขณะที่เรากำลังสูบอยู่จะไม่มีควันออกเล็ดลอดจากปากเลย
