It delivers fantastic flavour, lets you tweak your airflow, and even gives you a little vibration to let you know what's happening.

If you want a reliable and versatile vape, the Caliburn G2 is easily one of the best in its category.

Why the Uwell Caliburn G2 Is a Vaping Favourite

In a fast-paced world, whether you're navigating downtown or chilling at home, you need gear that's convenient and dependable.

A big reason for the Caliburn G2's popularity is that it delivers a genuinely satisfying vape without a complicated manual.

Your First Vape: Unboxing and a Super Simple Setup

There’s nothing like the excitement of getting a new vape, and the last thing you want is a complicated setup getting in your way. This guide is all about getting your Uwell Caliburn G2 out of the box and ready to go, making sure you feel like a pro from the very first puff.

The moment you open the box, you’ll find the sleek Caliburn G2 device, a pod that's already installed, a USB-C charging cable, and two different coils to try. You'll also see a user manual, which is always worth a quick look. It's a clean, simple kit that's designed to get you vaping right away.

Right off the bat, you'll notice how solid everything feels. The device has a satisfying weight, and the pod clicks into place perfectly. It just feels like a quality piece of kit.

What’s Inside the Box

So, what exactly are you getting? Let's break down the key components in your Uwell Caliburn G2 kit. Knowing what's what will make the setup a total breeze and help you get the absolute best performance out of your new device.

• The Caliburn G2 Device: This is the heart of the operation, housing the 750mAh battery and the firing button. It’s the engine that powers your whole experience.
• A G2 Replacement Pod: This is where the magic happens! It holds your e-liquid and features a comfy mouthpiece and a handy little window to check your juice level.
• Two UN2 Meshed-H Coils: You get a couple of options here. There's a 1.2ohm coil (already installed) for a tighter, more cigarette-like draw, and a 0.8ohm coil if you prefer a slightly looser draw with a bit more vapour.
• Type-C Charging Cable: This gets you back up and running quickly when the battery eventually needs a top-up.

This quick overview sums up the Caliburn G2's best features, showing how it balances power, performance, and a really smart design.

As you can see, the device is built to be a great all-rounder, giving you a strong battery and top-notch performance in a package that’s easy and comfortable to use.

Priming Your Coil for Amazing Flavour

Okay, this is probably the single most important step for getting a great vape: priming your coil. Seriously, don't skip this.

Think of it like getting a new sponge ready. You wouldn't use it bone dry, right? You let it soak up some water first. It’s the same idea here. If you vape on a dry coil, you’ll burn the cotton inside and get that awful, harsh taste known as a "dry hit." Nobody wants that.

Taking a few minutes to prime the coil properly ensures the cotton is completely saturated with e-liquid. This is the key to unlocking rich, authentic flavour and making your coils last way longer.

Here’s how to do it right:

1. Pop the pod out of the device.
2. Grab your new coil and put a few drops of e-liquid directly onto the little bits of cotton you can see on the sides. Three or four drops should do it.
3. Push the coil firmly into the bottom of the pod.
4. Fill the pod with your favourite e-liquid.
5. Now for the important part: let it all sit for at least 5-10 minutes. Go grab a coffee.

Trust me, this little bit of patience is rewarded with incredible flavour from the very first puff.

Filling Your Pod and Getting Started

Uwell designed the Caliburn G2 pod to be super easy and clean to fill. It has a slick top-fill system. All you have to do is snap off the black mouthpiece—wiggling it side-to-side helps—and you'll see the red fill port. Just stick the nozzle of your e-liquid bottle in there and fill 'er up.

Once it's filled and you've let the coil prime, just pop the pod back into the device. You'll feel a satisfying click when it's securely in place, which means you've got a solid connection. It’s worth remembering that different pods can have slightly different features; for more on that, check out our guide on the Caliburn A2 pods.

That's it! You're ready to go. You have two ways to vape: you can either just inhale on the mouthpiece to activate it (draw-activation) or press and hold the button as you inhale (button-activation). Give both a try and see which one feels more natural to you. Enjoy

Dialing In Your Perfect Draw with Advanced Features

Beyond the basics, the Uwell Caliburn G2 starts to show off some seriously smart features that put you in complete control. This is where the device stops being just a great vape and starts becoming your great vape. It’s all about customizing the experience to fit exactly what you like, and Uwell has managed to pack some impressive tech into this little package.

One of the most talked-about upgrades is the progressive airflow adjustment wheel. This feature alone is a massive step up, giving you a level of control you used to only find on much bigger, more complicated devices. It lets you fine-tune your draw with incredible precision.

Precision Airflow Control at Your Fingertips

Think of the airflow dial on the Caliburn G2 like tuning an old-school radio. You just turn a tiny red wheel on the pod, and each small click changes how much air gets mixed in with your vapour. It’s a beautifully simple mechanism that opens up a huge range of experiences.

Want a tight, warm Mouth-to-Lung (MTL) draw that feels a lot like a traditional cigarette? Just dial the airflow way down. This is perfect for newcomers or anyone who enjoys the punch of a higher-strength nicotine salt.

On the other hand, if you open it up, you get a much looser, airier Restricted-Direct-to-Lung (rDTL) vape. This style produces more vapour and is great for vapers who prefer a smoother throat hit and want to taste every single note in their e-liquid.

• Tight MTL: Close the airflow for that classic, cigarette-like feel.
• Loose MTL: Open it just a touch for a bit more air while keeping that familiar draw.
• Restricted DTL: Open it up for a cooler vape with bigger clouds.

This fine-grained control means the Uwell Caliburn G2 can adapt to your mood, your e-liquid, or even just the time of day. It's a truly personal system.

The Power of Pro-FOCS Flavour Technology

At the heart of the Caliburn G2’s amazing performance is Uwell's own Pro-FOCS technology. This isn't just a fancy marketing term; it's a patented system built to squeeze the most authentic and consistent flavour out of your e-liquid.

Pro-FOCS, which is short for Professional Flavour Optimizing Core System, works by meticulously controlling the heating temperature to atomize the e-liquid completely. This process makes sure every puff you take is loaded with pure, rich taste. It even recycles the airflow to re-vaporize any condensed e-liquid, so not a single drop of flavour goes to waste.

The end result? A vape that tastes incredible not just on the first puff, but stays that way right until your pod is empty. It stops the flavour from fading over time, giving you a delicious and reliable experience, every single time.

This tech is what makes flavours from brands like Lemon Drop or the exciting new Flavour Beast e-liquids really sing. All those subtle notes and complex profiles are brought right to the front, letting you taste the e-liquid exactly as its creators intended.

Smart Vibration Interaction

Another feature that really stands out is the device's clever haptic feedback. The Caliburn G2 actually "talks" to you through gentle vibrations, giving you key information without you ever having to look at an LED light. For busy commuters, this is an incredible quality-of-life upgrade.

The device will buzz to let you know about different things:

• Pod Connection: A quick vibration lets you know the pod is seated correctly.
• Low Battery: It gives you a heads-up when it's time to charge.
• Charging Complete: You'll get a buzz when it's back to 100%.
• Short-Circuit Protection: It warns you if something's wrong.

This intuitive, screen-free system is a game-changer for vaping on the go, providing essential operational alerts without being a dangerous distraction. You can read more about why GTA vapers are loving this device on Vape Barn's product page.

A Closer Look at the Coils, Pods, and Battery

Any great vape is more than just its looks. The real magic happens under the hood with the core components—the parts that actually create that amazing flavour and satisfying vapour. A device can have all the bells and whistles, but if the battery conks out halfway through the day or the coils just don't deliver, it’s a letdown. Let's get into what really powers the Caliburn G2 experience: its battery, pods, and coils.

We'll break down what makes these parts tick and translate the tech specs into what they actually mean for you. When you know how these pieces work together, you not only get the best performance out of your G2, but maintenance starts to feel less like a chore and more like a simple tune-up.

Understanding the 750mAh Battery

Uwell packed a solid 750mAh internal battery into the Caliburn G2, which is a nice little upgrade from some of its older siblings. So, what does that number actually mean for your day-to-day? Think of it as the device's fuel tank. For most people, it's got enough juice to get you through a full day of vaping without having to frantically search for an outlet.

This means you can grab it on your way out the door, use it all day at work, and still have some power left over for the evening. When it finally is time to charge up, the included USB Type-C cable gets you back in action fast, usually going from empty to full in less than an hour.

The G2 also takes the guesswork out of knowing your battery level with a simple LED light right under the fire button. No menus, no fuss. Just a quick glance tells you all you need to know.

• Green Light: You’re good to go with over 60% battery life.
• Blue Light: You're somewhere between 30% and 60%, so maybe start thinking about a charge.
• Red Light: Time to plug in! You’re running on fumes with less than 30% left.

This straightforward system means you’re never caught by surprise with a dead battery.

The Heart of the Flavour: Two Coils to Choose From

Now for the real stars of the show: the UN2 Meshed-H coils. These are the little engines that turn your e-liquid into vapour, and the G2 kit gives you two distinct options right out of the box. Your choice will come down to your personal preference and what kind of e-liquid you like.

First up is the 1.2ohm UN2 Meshed-H coil. This one is your go-to for a classic Mouth-to-Lung (MTL) draw—it's tighter, warmer, and more discreet. If you’re a fan of nicotine salt e-liquids, this coil is your best friend. It delivers that satisfying throat hit that closely mimics the sensation of a traditional cigarette.

Your other option is the 0.8ohm UN2 Meshed-H coil. This one packs a bit more punch, giving you a warmer vape and noticeably more vapour. It’s perfect if you prefer a looser, restricted Direct-to-Lung (rDTL) inhale. While it still works great with nic salts, it also really shines with lower-strength freebase e-liquids.

The beauty of the Caliburn G2 is its versatility. Just by swapping the coil, you can completely change up your vape, going from a tight, flavour-first draw to a cloudier, airier one in a matter of seconds.

Smart Pod Design for an Effortless Experience

Even the pod itself is smartly designed to make your life easier. It holds a solid 2 mL of e-liquid, and its clever features are all about convenience. One of the best things is the huge e-liquid viewing window. This crystal-clear panel lets you see exactly how much juice you have left, which is your best defence against a dreaded "dry hit"—that awful burnt taste you get from firing an empty coil.

Refilling is a breeze, too, thanks to the top-fill design. Just snap off the black mouthpiece to access the fill port. Not only is this super quick, but it also helps prevent messy leaks since the pod stays in the device while you top it up. When your pods eventually wear out, you can grab some fresh Uwell Caliburn G2 replacement pods right here to keep the flavour clean and crisp. All these thoughtful touches work together to create a smooth, enjoyable experience every time.

Keeping Your Caliburn G2 in Peak Condition

Just like any piece of gear you rely on, a little bit of care will keep your Uwell Caliburn G2 hitting perfectly day in and day out. Think of it like a quick tune-up for a bike – a few simple steps ensure you're always getting the best flavour and a smooth, consistent vape. We're not talking about complicated repairs here, just easy habits that stop common little problems before they even start.

A few minutes spent on maintenance goes a long way. It’ll help your coils last longer, keep your e-liquid tasting crisp and clean, and make sure your G2 is always ready to go when you are. It’s a small investment of time that pays off with every single puff.

Let's walk through how to keep your device in top shape.

An Easy Weekly Cleaning Routine

One of the best and simplest things you can do for your Caliburn G2 is to give it a quick wipe-down about once a week. It’s totally normal for a little bit of condensation from your e-liquid to build up where the pod connects to the device. But if you let it sit, it can sometimes mess with the connection between the pod and the battery.

When that happens, you might find the device doesn't fire right away, or the auto-draw feels a bit sluggish. The good news? The fix takes less than a minute.

Your Quick Cleaning Checklist:

• Pop the Pod Out: First things first, just pull the pod straight out of the device.
• Wipe the Contacts: Grab a cotton swab or a bit of rolled-up paper towel and gently wipe the gold-plated metal contacts you see inside the pod slot.
• Clean the Pod's Base: Give the bottom of your pod a quick wipe too, clearing off any moisture.
• Look for Debris: While you’re at it, have a quick peek inside the slot for any dust or pocket lint that might have snuck in.

Making this a regular habit keeps that electrical connection clean and strong, so your device works flawlessly every time.

Knowing When to Change Your Coil

The coil is the engine of your flavour, but it's a part that naturally wears out. Vaping on a tired, old coil is a surefire way to have a bad time, so learning to spot the warning signs is a game-changer.

You'll know it's time for a fresh one when you notice a couple of key things. The most obvious is a burnt or "off" taste. Instead of that bright, delicious flavour you expect, you get a harsh, almost scorched hit. Another big clue is muted flavour—your juice just tastes bland and washed out. You might also find you’re getting less vapour production than you’re used to.

As a rule of thumb, a coil usually lasts anywhere from one to two weeks. This can change based on how much you vape and the type of e-liquid you use. Really sweet juices, for example, tend to wear out coils a bit faster.

Swapping in a new coil is super easy and mess-free:

1. Pull the pod out of your G2.
2. Yank the old coil out from the bottom of the pod.
3. Prime your new coil by putting a drop or two of e-liquid on the little cotton windows on the side.
4. Push the new coil firmly into the pod until it's snug.
5. Fill your pod and let it sit for 5-10 minutes. This gives the cotton time to get fully saturated.

That's it! This quick swap will bring that fresh, amazing flavour right back.

Simple Fixes for Common Issues

Even the best-maintained devices can have a little hiccup now and then. Don't worry, though. Most of the time, the solution is incredibly simple and takes just a few seconds.

For instance, if you hear a gurgling or spitting sound when you take a puff, it usually just means the coil is a bit flooded with e-liquid. To fix it, take the pod out, wrap a paper towel around the mouthpiece, and give it a couple of firm flicks (like you're shaking down a thermometer). This will clear out the excess juice.

Getting weak vapour? The first thing to check is your battery. A low battery just doesn't have the oomph to produce a good cloud. If your device is fully charged, weak vapour is a classic sign that your coil is on its last legs and needs to be replaced. Knowing these quick tricks will help you keep your Uwell Caliburn G2 running like new.

Still Have Questions About the Caliburn G2?

Got a couple of lingering questions about the Uwell Caliburn G2? You're not alone. Let's tackle some of the most common things people ask, so you can get the best experience from your device right away.

How Long Do Caliburn G2 Coils Last?

This is probably the number one question we get, and the honest answer is: it depends on how you vape. For the average person, a Uwell Caliburn G2 coil will last anywhere from one to two weeks.

Of course, a few things can change that timeline. If you're a heavy vaper or you love super-sweet e-liquids, you might find yourself closer to the one-week mark. The best way to stretch out a coil’s life? Always prime new coils before you use them and try not to let your pod run completely dry.

Why Is My Caliburn G2 Leaking?

A leaky pod is a real pain, but thankfully, it's usually an easy fix. More often than not, the problem is just a coil that hasn't been seated properly. Before you do anything else, just make sure the coil is pushed all the way into the bottom of the pod until it's snug.

Another common culprit is overfilling. Always leave a little air bubble at the top and don't fill it past the marked line. If you've tried all that and it's still leaking, check the pod for tiny, hairline cracks—it might just be time for a fresh one.

One of the top reasons for performance issues is an improper pod connection. The Caliburn G2 uses a two-step system with magnets and a final 'click.' Always push the pod in until you feel or hear that click to ensure it's securely attached and making a solid connection.

What Kind of E-Liquid Should I Use?

The Uwell Caliburn G2 is pretty versatile, but it definitely has its favourites. For the best possible experience, we strongly recommend using nicotine salt e-liquids that have a 50/50 VG/PG ratio. This kind of blend works like a dream with both the 1.2ohm and 0.8ohm coils, giving you amazing flavour and a really smooth throat hit.

You can use freebase nicotine juices too, but try to stick to a blend that's no thicker than 70% VG. Anything higher than that can struggle to wick properly, which can lead to nasty dry hits.

Ready to experience the exceptional performance of the Uwell Caliburn G2 for yourself? At Wii Vape, we offer an incredible selection of devices, e-liquids, and all the accessories you need, plus free same-day delivery in the GTA on qualifying orders. Shop the Uwell Caliburn G2 now!
