First Impressions of the UWell Caliburn A3S
Look & Feel
The aluminium alloy casing on the A3S means that while it may be lightweight, it’s still made from stern stuff. The matte coating and fine detail work also make it feel like a premium product—and all of this fits into an extraordinarily compact little package at 109.8mm x 21.3mm x 11.7mm.
Another nice new feature is the battery indicator light, which is integrated into the device’s logo. You’ll see the word “Caliburn” in different colours depending on how much charge is left in the battery:
- Green: 60-100%
- Blue: 30-60%
- Red: Less than 30%
Meanwhile, the extremely minimalist design of the A3S gives it an elegant appearance—and while some people prefer their vape devices to be covered in buttons and screens, we think this is appropriate for a beginner-friendly vape.
Don’t get us wrong; we liked the firing buttons on other versions of the Caliburn—but not having one certainly eliminates the risk of accidentally firing up the A3S when it’s in your pocket or purse. Smooth moves, UWell.
Ease of Use
The A3S is made and marketed as a user-friendly device, and we’re happy to report that it doesn’t disappoint in this regard. Fill the pods from the top, pop them into the top of the device, and simply take your first draw. It’s like vaping with an automatic transmission!
Not only does this remove the risk of accidentally firing up the device when you don’t want to—it also gives the A3S a pleasantly discrete vibe. If you’re looking for a simple and portable vape you can use quickly without drawing tons of attention to yourself, there’s a lot going for this model already.
Using the UWell Caliburn A3S
Setting up the A3S is about as simple as it gets for a pod system. It’s compatible with A3 pods, so once you’ve filled one up with your chosen e-liquid and popped it in, all that remains is to make sure your device is charged and start enjoying it.
One of our favourite features on the A3S is how quick and easy it is to refill the battery. The supplied 2A fast charger will take you all the way to 100% in just 25-30 minutes, which means less time waiting and more time vaping.
Pod Filling & Setup
A3 pods fill from the top, which makes putting in e-liquid easy and helps prevent leakage. This isn’t a new feature, since the A3 pods have been available for a while—but it’s still just as nice as it ever was.
Meanwhile, the e-liquid window gives you a nice view of how much juice you have left, and the pods hold 2 mL of your chosen e-liquid. For best results, you’ll want to use a 50/50 nic salt e-liquid or one with a higher PG concentration.
You get a pleasant, easy MTL vaping experience here, just as promised. This isn’t a sub-ohm device, but the throat hit is nice and strong, and you’ll enjoy larger clouds than you might expect from a device so unassuming.
You can do DTL here as well, although it’s obviously not the intended application for the device. It won’t do any damage, though—so if you’re really in the mood, go for it! Just make sure you use a freebase e-liquid instead of nic salt e-juice.
The A3S should last you most of a day on a full charge. You shouldn’t expect marathon-level performance from that 520mAh battery at 16W—but again, that’s not really the point here. This is supposed to be a device you can pack up, carry around, charge quickly, and enjoy in short bursts without having to overthink the experience. A day or so of use per charge is just fine.
Should You Buy the UWell A3S?
Honestly, that depends on you. If you’re new to vaping and looking for something uncomplicated, this little pod system could be your new best friend. If you’re a box-mod loving, cloud-chasing vape veteran from way back, you’re probably going to be happier with something a little more intricate and customizable.
But taken on its own merits and bearing in mind its intended purpose, the A3S is a solid entry by UWell into their Caliburn series. It’s significantly less expensive than other Caliburn devices as well, so think of it as the most accessible way to enter the market for this popular and enduring series.
Frequently Asked Questions about the Caliburn A3S
Why is my battery indicator light flashing?
The battery indicator light on the Caliburn A3S flashes while you’re drawing—so don’t worry; this isn’t a sign of trouble! It shouldn’t flash for any other reason.
Do A3 pods have magnetic connections?
Yes! The A3 pods compatible with this device will be held in place magnetically once you pop them in, ensuring that they don’t come loose when the device is being stored or carried with a pod inside.
Is the Caliburn A3S leakproof?
The A3S is designed with numerous features to prevent e-liquid from leaking out. These include:
- Magnetic connectors to hold the pods in place
- A top-fill system for the A3 pods
- No risk of accidental firing (due to the lack of a firing button)
Please note that leaks can still occur if you draw too hard on the device’s mouthpiece, or if you use an e-liquid unsuitable for your device and vaping style. Stick to 50/50 or PG-heavy nic salt e-liquids if you’re MTL vaping, and only use freebase e-juice for DTL sessions.
What is the difference between the 0.8Ω and 1.0Ω pods for the Caliburn A3S?
We recommend using the pod with a 0.8Ω preinstalled coil for tight MTL draws and the pod with a 1.0Ω coil to enjoy fuller flavours during DTL sessions.
