Our Verdict

The Caliburn Tenet Koko performs just as well as the Caliburn G2 and this makes it another great Caliburn device from Uwell. If you want excellent flavor from a pod vape that takes replaceable coils, I think that the choice of grabbing the Tenet Koko over the G2 will come down to the design alone.

If you prefer the look of the Tenet Koko then by all means you can get this device. However, for those who are reading this review and liking what they’re reading about the performance, but who may not be so sure about the design, the G2 will get you the same performance in a much nicer looking package.

Honestly, I don’t see the need for the Tenet Koko when we already have the G2, but I guess that the variety in the designs of vape devices is something that some users like.

In any event, the build quality, flavor, draw, battery life, and coil life are all great with the Tenet Koko. If you like the steampunk-style design then you’ll definitely enjoy using this device.

Since the release of the original Uwell Caliburn, the Caliburn series of devices have become some of the most successful pod vapes to ever hit the market. Why? They’re easy to use, reliable, and they produce good flavor, and these are just a few of the many reasons why the Caliburn series has become, and remained, so popular.

There are two types of Uwell’s Caliburn series devices: The Caliburn “A” series and the Caliburn “G” series. The A series of devices uses pods with built-in, non-removable coils, while the G series of devices uses pods that take replaceable coils. 

The Caliburn Tenet Koko that I’m reviewing today does not have an “A” or “G” series designation. However, it uses the same pods as the Caliburn G2 and comes with the same user-replaceable coils as well. This makes the Caliburn Tenet Koko most similar to other G series Caliburn devices.

Depending on the coil that you use, the Caliburn Tenet Koko can output up to 18W and it has a 950mAh battery that can be recharged with 2A Type-C charging. It’s compatible with all G series coils and it comes with a single 2ml capacity pod.

In addition to these basic specifications, the Tenet Koko also features a handy ejuice viewing window, haptic feedback, and airflow adjustment. 

Is the Tenet Koko another Caliburn series pod device that you should consider?

Design & Build Quality

  • Uwell Caliburn Tenet Koko - 1

The Caliburn Tenet Koko is a square shaped device just like other Caliburn Koko pod vapes. It’s 73.7mm tall, 50mm wide, and 18mm thick. This makes it slightly larger than other Koko devices and it feels a bit more bulky in the hand. But despite the larger size, it’s still a portable device that I have no problem putting in my pocket. It weighs 61.5g though and you can definitely feel the weight.

The design is radically different from other Caliburn devices and I’m not sure if this is a good thing. The Tenet Koko, like the Caliburn Tenet, has a steampunk-esque design and features bolts and rivets throughout. Uwell says that it’s a “wasteland and mechanical style”. I’m personally not too keen on how it looks but I’m sure that there are some vapers out there who will like this sort of design.

The body of the Tenet Koko is all metal and made through a die-casting process. It features an electroplated coating to achieve the retro look, as well as to provide more grip and improved durability. There are four colors available: copper, gray, red & black, and black& white. I received both the copper and black & white colors for this review and, while I don’t particularly love the design, the copper color matches the best with the theme of the Tenet Koko.

So far, the body of my Tenet Koko has held up well during my few weeks of use. There’s no paint fading and the body is resistant to scratching or chipping. Also, due to the partially faded and uneven paint from the factory, any wear won’t stand out or be obvious. The electroplated coating is also fairly grippy even though it looks like a smooth and slippery device.

Right below where the pod inserts into the top of the device there is a large ejuice viewing window. This window is cut out from the body of the device and allows you a direct line of sight into the pod. The pod is basically clear, with only a very light frosting, so it’s very easy to see into the pod with this viewing window. I’ve used it quite a bit to check on my ejuice level and I’ve found it to be pretty convenient.

There’s a lanyard anchor spot on one corner of the Tenet Koko and you get a chain lanyard included in the box. I’m not too fond of the chain lanyard so I used another one that I had lying around. The 61.5g weight of the Tenet Koko is a little heavy to have around the neck but it’s fine for shorter periods of time when you need to have your hands free with your vape near.

At the bottom center of each side there is an LED light. This LED lights up when you insert or remove the pod, take a draw, or charge the battery. You also get haptic feedback when you insert or remove the pod.

On the topic of the pod, it pressure-fits into the top of the device and once it’s inserted it’s quite firm with no wiggle or movement. But one issue that I’ve encountered is that when I put the device down or into my pocket, I’ll go to take a draw and it won’t fire. 

What ends up happening is that the pod gets slightly loose and rises up just a bit from the battery, which means that there’s no longer a connection. I would have to push the pod back down to click it back into place and then it would work again. This is a minor inconvenience for sure and it only takes a half second to fix the issue but it’s still annoying when it happens repeatedly during the course of a single day.


Pod & Coils

Uwell Caliburn Tenet Koko - Pod and Battery

The Caliburn Tenet Koko uses the same pods as the Caliburn G2. These pods are clear, so they’re easy to see into, and they take replaceable coils. This pod is compatible with all G series coils and there are three available:

  • 0.8Ω Coil (included)
  • 1.0Ω Coil (sold separately)
  • 1.2Ω Coil (included)

Uwell Caliburn Tenet Koko - Coils

As with all Caliburn pods, it’s frustratingly difficult to remove the top cap. The top cap is secured in place by tiny clips and it’s really a struggle to get the cap off. The easiest way to remove it is by pushing the cap backwards while the pod is still secured in the device, or by getting a nail under the large side of the cap and prying it up. Either way, it’s always a struggle.

Once the top cap is removed, you’ll see a red gasket, the vapor pathway, and an air-relief hole on the top of the pod. The underside of the top cap is also fitted with a rubber gasket to prevent leaking.

Uwell Caliburn Tenet Koko - Pod Fill Port

To fill the pod you’ll want to only use the hole with the red gasket. When you insert your bottle tip the hole will open up and when you remove the tip it will self-close. Do not try to fill ejuice in either of the other holes, especially not the center hole.

The coils have a flat side which you have to line up with the flat side on the bottom of the pod. Other than that, they easily push in and remain securely seated once inserted.


Airflow Adjustment

Uwell Caliburn Tenet Koko - Pod Airflow Adjustment Wheel

Since these are the same type of pods as the ones for the Caliburn G2, they also feature the same type of airflow adjustment which is a wheel near the bottom of one side of the pod. This airflow placement means that you have to remove the pod in order to adjust the airflow, which isn’t the most convenient way to do it, but it’s better than no airflow adjustment at all.

The wheel has a bit of resistance to it, so it stays where it’s set. You can use your finger to gently turn the wheel and set the airflow to your preference.

The airflow will depend on which coil you’re using, with the 1.2Ω coil delivering a slightly more restricted draw than the 0.8Ω coil. By adjusting the airflow you can set the Tenet Koko to a MTL draw, a RDL draw, or to an airy DL draw.


Battery Life

Uwell Caliburn Tenet Koko - 7 Charging Port

The Tenet Koko has a 950mAh battery, which is 200mAh larger than the 750mAh battery on the Caliburn Tenet. It also outputs a relatively low maximum wattage of 18W so the battery life is more than good no matter which coil you use. In my personal experience, the Tenet Koko lasts for a few days of moderate to heavy vaping before needing to be recharged.

The LED indicator on the bottom of the Tenet Koko display your battery life with three colors, red, blue, and green. Each time that you take a draw, the LED lights up to indicate how much battery life you have left:

  • Green: 60%+
  • Blue: 30-60%
  • Red: Less than 30%

The Tenet Koko takes 50 minutes to recharge when plugged into a laptop with Type-C to Type-C charging and it should be a similar charge time if plugged into a wall charger.


Performance

Uwell Caliburn Tenet Koko - 9

Since the Tent Koko uses the same pods and coils as the Caliburn G2, I found that it performs very similarly. It delivers the same great flavor, a warm draw, and airflow that can be set to anywhere from MTL to DL, with even RDL being a possibility. Both coils fared well with 60VG and 50/50 ejuices with no leaking or issues with wicking. I also refilled 10 times with both coils before starting to taste any drop off in flavor, so the coils last a long time too.

The 0.6Ω coil is best for RDL and DL vaping and I used 20mg and 25mg nicotine salt ejuices with this coil. The draw is a little strong with these nicotine strengths so I wouldn’t suggest going any higher. You can get a MTL draw with this coil by closing down the airflow all the way, but the flavor and vapor become very muted and the vapor becomes very dense and harsh. Keeping the airflow just slightly closed for a slightly restricted DL draw is the way to go with this coil.

The 1.2Ω coil is more restricted than the 0.6Ω coil when wide open and it can also be effectively used for MTL vaping. I used the same 20mg and 25mg nicotine salt ejuices and, although I found the flavor to be a little less prominent than with the other coil, it’s still a great experience. The throat hit is good and the MTL draw is perfect without muting the flavor at all. This is the coil to use if you’re a MTL vaper, although you can also use it for RDL vaping by opening up the airflow.


Verdict

The Caliburn Tenet Koko performs just as well as the Caliburn G2 and this makes it another great Caliburn device from Uwell. If you want excellent flavor from a pod vape that takes replaceable coils, I think that the choice of grabbing the Tenet Koko over the G2 will come down to the design alone.

If you prefer the look of the Tenet Koko then by all means you can get this device. However, for those who are reading this review and liking what they’re reading about the performance, but who may not be so sure about the design, the G2 will get you the same performance in a much nicer looking package.

Honestly, I don’t see the need for the Tenet Koko when we already have the G2, but I guess that the variety in the designs of vape devices is something that some users like.

In any event, the build quality, flavor, draw, battery life, and coil life are all great with the Tenet Koko. If you like the steampunk-style design then you’ll definitely enjoy using this device.

I started vaping in 2013, determined to quit smoking because I knew it was a terrible habit. Many hard years later, I'm smoke-free and feeling better than ever! I love trying as many different tanks, mods, and ejuices as I can get my hands on, but I love sharing my experiences and honest opinions even more! When I'm not reviewing, researching, or writing, you can find me watching tennis, tinkering with coils, or playing with my two mischievous cats.
