Uwell Caliburn A2 Replacement Pods Review - User Guide for Uwell Caliburn A2 Pods

The Caliburn A2 is Uwell newest pod system and the successor to the original Caliburn, one of the most popular vapes ever. It is, in reality, the third Caliburn, since Uwell launched the G last year, which is part of another Caliburn sub-line, but more on that later.

Well, here's what the Uwell Caliburn A2 Replacement Pods has in store for us. It is a simple pod system with interchangeable pods that store up to 2 mL of juice and a built-in, newly designed 0.9-ohm coil. It is powered by a draw and a button, has a 520 mAh battery, and charges through Type-C, however it is not included with the kit.

I was never a great fan of the original since I was never sure what the appeal was meant to be. I used it as an RDL vape, although there were better alternatives in this area. But I really enjoyed the G, which I reviewed a while back, so let's see how the A2 compares to past Caliburn and whether it's worth your time.

Design and Build quality

Before I get into the design of the A2, let me give you a little history of the Caliburn family. The Caliburn A2 is a direct sequel to the original and a member of the A line, but the Caliburn G, which debuted in 2020, is a member of its own line. The "A" comes from the Greek letter alpha, and the line has easier-to-use and more beginner-friendly items, whereas the "G" comes from Great/Grand, and the line features more customized and complex products.

Uwell Caliburn A2 Pods  is very identical to the original Caliburn and somewhat smaller than the G. It measures 110.1 mm x 21.3 mm x 11.7 mm and weighs 33 grams with the pod attached. While not the tiniest pod vape on the market, the A2's overall size is practical, and it slips effortlessly into and out of the pocket.

The gadget is available in six colors, the most noticeable of which are the blazing orange and the iris purple, both of which were used in the original Caliburn. From a design standpoint, there are two key improvements over the original: a Type-C charging connector and a huge glass on the front for quickly viewing energy levels. My only slight quibble with the window is that it only has one side open, so you'll need some light to see what's going on inside.

The mouthpiece has also been changed; it is substantially thinner than the G's mouthpiece and similar in form but smoother than the original Caliburn's mouthpiece. In fact, the word "smooth" perfectly describes this equipment. Uwell did away with the rough edges, giving the A2 a more contemporary appearance and a more pleasing hand feel.

Starting Again

Since the Uwell Caliburn A2 Pod is part of the beginner-friendly range, using it is as simple as it gets. Uwell preserved the previous Caliburn's' practical top fill, so you only need to slightly push the mouthpiece on the flat side to remove it. Next, just insert the nozzle of your juice bottle into the red-marked hole at the top of the pod and fill it up. Replace the mouthpiece, leave the gadget away for five minutes, and you're ready to go.

The gadget is turned on and off with five clicks, and because the A2 is both button and draw-activated, you may choose whether to push the button for a warmer vape or just inhale via the mouthpiece. The coils are incorporated into the pod, and fresh pods come with their own mouthpiece, so you can recycle the mouthpiece and throw away the rest of the pod when it starts to taste funny—or proactively after a week.


Since the A2's pods have been altered, this gadget is not compatible with the original or G's pods. There is just one pod available, and it has 0.9-ohm coils using Uwell's Pro-Focus technology. Other than the fact that it focuses on flavour, there isn't much information about this technology on their website. It also delivers.

The flavour from the A2 is clear and sharp, similar to what I've been receiving from the Innokin Zlide. Pods have come a long way in the previous several years, and the A2 is up there with the finest in terms of flavour. Even while the device could readily handle the 75 VG juice I tried it with, this is especially true with 50/50 juices.

In terms of coil life, I began to notice a bit of juice in my mouth after the sixth or seventh refill, but the flavour remained unaffected. The coil began to fail around the tenth or eleventh refill, and I had to replace it. That's more than 20 mL, which isn't terrible for a gadget that uses built-in coils.

One thing I should mention is that the A2's sensor occasionally feels like it wants me to add a small bit more lung motion in there. In fact, in auto-draw mode, it seems just slightly tighter than the original's airy MTL/tight RDL vape. By utilising the button, however, it is a nice and warm MTL with a definite throat impact. In button mode, both my 20 mg salts and my 9 mg standard nic juice shone.

The draw is not extremely tight, but I believe it is at or near the sweet spot for the majority of MTL vapers. I ended up pushing the button the most of the time, but I loved how the two experiences were slightly different, & I did occasionally use the sensor when I wanted a cooler, looser impact.

When I evaluated the Caliburn G, I was extremely pleased with the performance of the coils and didn't have any big leakage issues—though, according to what I've read online, some weren't so pleased. Yet, even after being unused for days, the contacts on the A2 are bone dry. Uwell deserves credit for nailing their anti-leaking design, and I sincerely hope the pods remain similar throughout batches.

Charging & battery life

The Caliburn A2 charges using a Type-C connection located at the bottom of the device. I clocked a full charge at 52 minutes, however Uwell says that it can charge to 90% in 35 minutes.

In terms of battery life, expect to get through about one and a half pods every charge. That's around 3 mL, which is the industry norm for tiny vapes—if not slightly more.

Lastly, there is an LED light towards the bottom of the device's front that functions as a battery indicator:

  • Green: 60-100%
  • Blue: 30-60%
  • Red: 0-30%

The Advantages and Disadvantages

  • Lightweight and portable
  • Extremely simple to use

  • The juice window is a welcome addition.
  • Simple top filling
  • Activated button and sketch
  • Coils last around 20 mL Excellent taste
  • MTL satisfaction while using the button
  • There is no leakage or condensation.
  • Excellent battery life (around 3 mL on a charge)
  • Type-C charging is quick (52 minutes)
  • Only one side of the juice window is visible.
  • There is just one coil choice.
  • After 5-6 refills, a small amount of juice remains in the mouth.
  • The Type-C charging cable is not included.

Wrapping It Up

While the  Uwell Caliburn A2 Replacement Pods does not provide anything particularly novel, it is a reliable vape. Its airflow caught me off guard because I expected Uwell to keep with the halfway MTL-RDL airflow that people seemed to like on the first Caliburn. While they did, because it vapes similarly to the OG in auto-draw mode, using it with a button provides some of the most tasty and warm MTL action I've experienced on a pod vape.

If the original was too light for your sort of MTL, the A2 could be just what you're searching for. And whether you are a newbie vaper or a vaper looking for a solid pod system, the A2 is worth considering. With robust coils and a basic yet attractive design, it is almost a leak proof pod system.
