Sit back and read on as we explain all of the key features and potential drawbacks of the latest device from the Uwell Caliburn series – the Uwell Caliburn A2S, with our comprehensive review.  

Set at a reasonable price of under £15 with two refillable pods included with the pack, it’s a decent little kit to get you started in vaping as you move away from disposable vapes that are single-use and certainly from cigarettes, which we know poses serious risks to human health.  

This review will explain all you need to know so you can understand if the Uwell Caliburn A2S is the right product for your vaping experience.

Can it Be Used as a Transitional Device for Smokers?

Absolutely, Uwell is renowned for creating vape kits that help people put down cigarettes for good and swap them for an electronic device that provides the necessary nicotine, throat hit and flavour performance.   

This is all thanks to the Pro-Focs pods technology that is synonymous with the Caliburn range.  

With a simple yet effective design, operational functionality and side fill method, the device is as easy to top up with e-liquid as it is to vape.  

Like most popular devices that cater to former smokers, the A2S is automatic draw inhalation by puffing on the mouthpiece like you would a cigarette. The pods offer a 2ml capacity to store enough e-liquid and mesh coils to maximise flavour.

How Does the Caliburn A2S Perform?

It is exactly what you get for under £10 from a brand as big as Uwell. The device is reliable and offers a discreet amount of flavour to replicate the sensation of smoking without inhaling thousands of dangerous toxins.  

The flavour itself is stellar, utilising the patented Pro-Focs technology they are renowned for and consistently good from the first puff to the last of the 2ml Uwell Caliburn A2S pods.  

And because it’s auto-draw only, the transition from smoking to vaping is a seamless switch.

How to Use the Caliburn A2S Pod Vape Kit: Quick Setup Guide

1. The device turns on automatically when the pod is inserted on the top of the battery.  
2. To charge, put the USB cable into the port at the bottom of the device.  
3. To fill the device, pop the plastic plug on the side and fill it with your chosen e-liquid.  

Appearance and Best Layout Design Features

It is a smart intuitive device that does not require any adjustment of wattage, or alteration of the pods. What we like about this device is the large comfortable mouthpiece and the very clear e-liquid window.  

And even better yet, the pods are just as visible so you will always be aware of how high or low the vape juice levels are to prevent a burnt coil.  

This means easy vaping and simple filling of whichever e-liquid suits you at the moment!  

Another cool addition to the Caliburn A2S is the LED ‘animated light matrix’ which creates an element of intrigue for onlookers catching a glimpse of the device. The device itself is available in six colour schemes, including gradient, black, gold, purple, grey and blue.

What E-Liquid is it Best Paired With?

Thanks to the mesh coils that you can use with the Uwell Caliburn A2S, this ensures long-lasting consistent flavour. But how do you pick the right e-liquid to go with the device?  

Well, the pod coil resistance of 1.2 Ohms is a good indicator, highlighting a tight mouth-to-lung draw which means it would be best paired with a high PG e-liquid. But 0.9 Ohm pods are compatible with the kit too, which are purchased separately.  

Therefore, you will want to choose a thin e-liquid with a tobacco, menthol or fruity taste based on personal preference to pair with the A2S and experience a similar sensation to smoking.  

Battery Life and Charging

The Uwell Caliburn range is not known for its huge battery capacities, so this factor depends on how frequently you use the device. For example, the Caliburn A2S offers a 520mAh battery life, which isn’t huge but not the smallest either.   

If you charge it first thing in the morning before leaving or just before bed, it should be enough to last a mouth-to-lung vaper the majority of the day but may still need an additional charge if frequently vaped.  

What we do like is the LED battery indicator, which makes the logo flash when it’s charging. The time it takes to fully charge is very quick at 40 minutes for a full charge thanks to the type-c port, so overall it’s a good quality battery but would ideally be a bit bigger capacity for future pod devices from Uwell.

Final Verdict

To summarise, this is another device in the Caliburn series which as a stand-alone product (if you have never owned a Caliburn before) would be a welcome addition to any MTL vaper. It is compact, lightweight to hold at 30g and very simple to use with features like auto-draw and fast charging capabilities.   

Compared to the other Caliburn kits (more than 20 available at the time of writing), it is quite like previous models such as the A2 and A3 Caliburn devices with the same Pro-Focs pod technology and build quality.   

The battery capacity is a bit on the small side, but overall, the Caliburn A2S is a stylish and effective kit for vaping on the go, boasting two pods for added value to get any vaper off to a good transition from smoking and certainly saves money compared to disposable vapes!
