The Caliburn name has been a mainstay in our best pod vape list and for good reason.
However, it seems Uwell has the knack for releasing minor iterations to already excellent pod vapes. So what does the A3s have to offer?
It is essentially a stripped-back version of the Caliburn A3 with a similar design but no manual firing.
It comes with a 520mAh battery that can be charged via USB-C with a charge rate of 2A. It also has a maximum output of 16W, a step up from the A3.
The A3s comes with Uwell’s latest upgraded pod with a 0.8Ω resistance and a 1.0Ω pod. Both pods have a side-fill system, but the A3s is also cross-compatible with the top-fill A3 pods. The Caliburn is available in 6 colors: Moonlight Silver, Space Gray, Midnight Black, Lake Green, Iris Purple, and Ocean Flame.
- Compact design
- Good build quality
- Easy to use
- Excellent Auto-draw
- Fantastic flavor from both coils
- Well-designed LED indicator
- Compatible with regular A3 pods
- No leaking or dry hits
- Comfortable mouthpiece
- USB Type-C fast charging (2A)
- No Adjustable Airflow
- No Adjustable Power
- Relatively small capacity battery (520mAh)
The Bottom Line
The Caliburn A3s delivers an excellent vape, in line with all other Caliburns in the range. It’s essentially a stripped-back version of the A3 with the same excellent design and form factor. There’s no adjustable power or airflow, but both included pods deliver fantastic flavor (with slightly more punch on the 0.8Ω). The A3s is one of the easiest to use and affordable pod systems on the market and would be a significant step up for anyone using disposables – recommended.
Specs and Features
Design & Build Quality
Uwell has followed a very similar design language with all of their recent Caliburn pod systems, and the A3s is no different.
At first glance, it looks exactly like its bigger sibling, the A3, just without a designated fire button.
While that’s true and definitely not a bad thing, as the A3 is a well-designed pod system, you’ll notice some minor differences on further inspection.
On the aesthetic front, the A3s has some nice laser sketched lines adorning the front of the device in place of the manual firing button.
However, the real difference to the Caliburn A3 comes under the hood and with the included pod.
The A3s comes with Uwell’s latest pod with a lower resistance of 0.8Ω. The device also has a maximum output of 16W to make the most of the lower resistance.
The A3s pods are contained units and sadly lack any type of top-fill system. However, the A3s is cross-compatible with A3 pods if top-fill is a must for you.
The A3s device is perfectly lightweight and compact with the same dimensions as the A3: 109.8 × 21.3 × 11.7mm.
It also features the excellent and stylish LED indicator light fashioned out of the Caliburn logo.
On the base of the device, you’ll find the USB-C port for charging at a rate of 2A. There’s no cable included in the kit to keep the costs down, as this is the most affordable of the Caliburn line.
Overall it’s a familiar and well-executed design. Even though it’s only a slight iteration over previous Caliburn designs, there is no point in changing something that looks and works well. That’s exactly what the A3s is; a good-looking, compact, and easy-to-use pod system.
The Caliburn A3s is one of the simplest pod systems in the range and therefore doesn’t come with stacks of features.
It is designed to be a step up from disposables at an affordable price, so its focus is on ease of use.
The A3s comes with an in-built 520mAh battery that can be charged via USB-C.
It supports fast charging at 2A, but there is no USB-C cable included in the kit.
The A3s has a maximum output of 16W, but there are no adjustable power settings. Instead, it will set the power according to the resistance of the pod attached.
There is no manual firing or on/off button with the A3s. Instead, it relies solely on auto-draw to function. As with all other Caliburn devices, the auto-draw trigger works exceptionally well.
There’s also no adjustable airflow with the A3s, so you will be limited to the draw provided by the pod in use. There are two small airflow holes on either side of the device, and it typically delivers a draw that we’ve become accustomed to from Caliburn pods which is on the loose MTL side.
The Caliburn A3s does have an LED indicator light on the front of the device, which is neatly designed in the style of the ‘Caliburn’ logo. It’s in a perfect position to see while you are vaping and lights up nicely without being too obnoxious.
There are 3 LED colors that correspond to the following battery levels:
- Green = 60-100%
- Blue = 30-60%
- Red = <30%
The Caliburn A3s comes with two pods, which for a budget device, is commendable.
It drives me crazy when companies only include one pod; what happens if that pod is faulty? So definite props to Uwell for including two.
Uwell has also clearly decided to distinguish between their A and As lines with the style of pods. The A ranges come with top-fill pods, while the As range has more simplistic side-fill pods (like the A2s).
However, in my experience, there is absolutely no difference in their performance; it’s just an alternative fill method.
The two pods included (as with all Caliburn pods) have a 2ml capacity, which means they also cater to TPD-restricted areas.
There are two different MTL resistances included:
- 0.8Ω – FeCrAl Meshed
- 1.0Ω – FeCrAl Meshed
I believe we have seen the 1.0Ω before in previous Caliburn ranges. However, the 0.8Ω is a new pod, and Uwell claims to have improved their Pro-FOCS flavor adjustment technology with his coil (more on this later).
Thankfully Uwell also took the wise step of making the A3 and A3s pods cross-compatible. So if you prefer the A3 pod’s top-fill method, you can use those instead, or vice versa.
The fill plug on the side of the A3s pods is easy to open and close, and the fill hole is large enough to accommodate larger tips.
The performance the Caliburn A3s delivers is on par with other recent Caliburns – which is great.
The only noticeable difference with the A3s comes with its 0.8Ω pod. Which gives you a slightly warmer vape and a little more punch to the flavor than other Caliburn pods.
The 0.8Ω might just be my favorite from all of the available pods just, solely based on the flavor it keeps producing, even after several refills.
However, the A3s doesn’t have any form of adjustable airflow, and the 0.8Ω is definitely the loosest draw (of the two pods included) and is an extremely loose MTL draw.
If you prefer your MTL draw to be a little tighter, the 1.0Ω is the way to go, and you are only sacrificing a little warmth.
It’s also worth noting the A3s only has a 520mAh battery, so it does deplete a little quicker with the lower resistance pod.
That being said, there’s still enough capacity to get you through a day of moderate vaping, and the 2A charge does replenish things rather quickly.
When it comes to auto-draw, the trigger on the A3s is as good as any other pod I’ve tested. It fires instantly on the inhale and works pretty much flawlessly.
I’m also happy to report that I didn’t experience any leaking or spit back with either pod during my testing time, which is also a major plus.
The Caliburn A3s is not going to blow you away with a vape experience that you’ve never had before. However, what it does do is deliver an excellent quality vape (in line with other Caliburns) in an easy-to-use, stylish, and cost-effective package.
The Uwell Caliburn A3s is precisely what you’d expect from an ‘S’ iteration of the popular pod line.
It delivers the excellent ‘Caliburn’ experience that has become much-loved among pod vapers.
The overall design is stylish, yet simplistic, and the A3s is one of the easiest-to-use pod systems you will come across.
The new 0.8Ω pod brings a little more warmth and flavor to the party (and is also cross-compatible with other A3 devices).
If you are looking for a new affordable pod vape or just want to upgrade from using disposables, the Caliburn A3s is an excellent choice.
