Uwell Nunchaku 2 Vape Kit: Overview

The Uwell Nunchaku 2 Vape Kit is a refillable pod mod from Uwell, a Shenzhen-based manufacturer that has been making vaping hardware for around a decade and is mainly known among UK vapers for the Caliburn pod range. The Nunchaku 2 sits a step above those slim, fixed-output pen pods. It is a larger, adjustable-wattage device that takes a mesh-coil pod, a refillable reservoir and a built-in rechargeable battery, and it is aimed at vapers who want more control over their setup than a basic starter pod allows.

Because single-use disposable vapes were banned across Great Britain on 1 June 2025, refillable kits like this have become the practical route for adult smokers and existing vapers who want a compact, pocketable device. Instead of throwing away a battery and a plastic body every few days, you keep the hardware and replace only the pod or coil when it wears out. That is cheaper over a month and far easier to recycle responsibly.

This guide explains what the kit actually does: how it performs, which liquids suit it, how long the battery lasts, how the coil works, which nicotine strengths make sense under UK rules, who should buy it, how to use it, what to do when it misbehaves and how it compares with similar kits. The product family on this page has 5 variants. These are finish or colour options of the same device rather than different flavours, so everything below applies to all of them.

• Type: refillable pod mod kit with a built-in battery
• Output: adjustable wattage, with a ceiling in the region of 80W according to Uwell's published figures
• Coil: proprietary mesh-coil pod, replaceable
• Charging: USB-C
• Intended users: adult smokers and existing vapers aged 18 or over

A note on specifications. Where figures appear on this page they reflect the class of hardware the Nunchaku 2 belongs to and the numbers Uwell publishes, but batches and regional versions differ slightly. If the specification table on the product listing shows something different, treat the listing as the authority.

Vaping products contain nicotine, which is addictive. They are intended for adult smokers and existing vapers, are not risk-free, and are widely regarded as a lower-risk alternative to smoking tobacco. If you do not smoke, there is no reason to start.

What Is in the Box and What You Still Need to Buy

The Nunchaku 2 kit is sold as a complete starting point, but it is worth knowing exactly what is and is not included so you are not caught out on day one. Contents can vary slightly between retailers and production batches, so always check the listing, but a typical kit includes the following.

• The Nunchaku 2 device with its built-in battery
• A pod with a mesh coil installed, ready to fill
• A USB-C charging cable
• A user manual and warranty card
• In many kits, a spare coil or pod

What the box does not contain is e-liquid. You will need to buy that separately, and this is where UK rules matter. Nicotine e-liquid sold in the UK is capped at 20mg/ml (2%), bottles of nicotine liquid are limited to 10ml, and refillable tanks and pods on nicotine products are limited to 2ml. The Nunchaku 2 is sold in some markets with a larger pod, but UK-market kits are supplied with a pod sized to fit the 2ml limit. If you see a listing offering a much larger pod to UK buyers, be cautious about where it came from.

You will also want a few extras that are easy to overlook.

• Spare coils or pods. A mesh coil is a consumable. Having a spare means you are never stuck when flavour starts to fade.
• A decent USB-C wall adapter. A 5V adapter from a reputable brand charges more predictably than a random cable plugged into a laptop port.
• A small case or pouch. A pod mod is sturdy enough for a pocket, but keys and coins will scratch the finish.
• Tissue or a microfibre cloth. Refilling is tidy once you are practised, and a cloth takes care of the occasional drip.

Choosing your first bottles is the single biggest decision after the hardware itself. Start with a 50/50 or 60/40 PG/VG liquid in a nicotine strength matched to your habit, which we cover in the nicotine guidance section below. Thicker, high-VG liquids can slow wicking in small pods, so they are better saved for once you know how the device behaves.

Finally, remember that nobody under 18 can legally buy or be sold vaping products in the UK. Expect age verification at checkout and on delivery.

Design and Build Quality

Physically, the Nunchaku 2 is a compact pod mod rather than a pen. It is wider and heavier than a slim pod system but still sits comfortably in one hand and slips into a jacket or jeans pocket. The body is a metal alloy shell with a coated finish, which gives it a solid, slightly weighty feel compared with all-plastic budget kits. The five variants in this family differ in colour and finish, so you can match your taste without changing anything about how the device works.

A few design points are worth looking at closely.

• Pod fit. The pod seats into the top of the device and is held in place by a firm click. A pod that clicks in properly is the first line of defence against leaks and intermittent firing, so press it home each time you refit it.
• Fill port. The fill opening is covered by a silicone bung. It needs to be seated fully after every refill. A half-seated bung is the most common cause of a sticky, leaking device.
• Controls. Wattage and settings are adjusted using the controls on the body, with feedback from the indicator or display. Read the manual once through, because Uwell devices use multi-press shortcuts for locking and switching on and off.
• Airflow. The draw is adjustable, so you can tighten it for a restricted mouth-to-lung pull or open it for a looser, airier inhale.
• Mouthpiece. It is a standard shape that is comfortable for long sessions and easy to wipe clean.

Finish durability depends on how you carry it. Coated metal bodies tend to show wear on edges first, and light scratches are normal for any pocket device. A case helps, though we would not call this a fragile product. It handles everyday knocks, but like any lithium-powered electronic it should not be dropped repeatedly on hard floors, left on a car dashboard in summer or exposed to rain.

One honest limitation is size. If you are coming from a very small pod system, the Nunchaku 2 will feel chunky. The trade-off is a larger battery and more adjustability. If pocket size is your top priority, a slimmer kit may suit you better, and we say so in the comparison section further down.

Performance and Puff Delivery

The Nunchaku 2 is a variable-wattage device, so its performance depends heavily on how you set it. That flexibility is the point of the kit. At lower wattages it behaves like a gentle mouth-to-lung pod system, producing a cooler, tighter vape with modest vapour. Turn the output up and the same hardware gives a warmer, denser draw with noticeably more vapour, closer to what some vapers call restricted direct-to-lung.

Puff counts for a refillable device are not a fixed figure the way they are for a disposable, because they depend on the setting, the liquid and how you vape. As a practical guide for a 2ml pod:

• Lower wattage, tight mouth-to-lung draw: roughly 250 to 350 puffs per fill is a realistic range, and a fill can last most of a day for a moderate vaper.
• Mid-range wattage, looser draw: expect fewer, in the region of 150 to 250 puffs per fill, because more liquid is vaporised with every pull.
• High wattage, open airflow: a 2ml pod empties quickly, and heavy users will refill several times in a day.

These are estimates, not promises. Puff length matters as much as wattage, and a slow five-second draw uses far more liquid than a short two-second one.

Ramp-up on a mesh coil is quick. After a short priming period on a new coil, you should get vapour almost as soon as you press the button or inhale, with no lengthy pause. Consistency is where mesh generally earns its place. Because the heating surface is large and evenly wetted, the first puff after a break tastes much like the tenth.

There are limits. At the top end of the wattage range, a small 2ml pod cannot keep up with a determined chain-vaper, and you will see flavour thin out or notice a hint of burnt taste if the cotton runs short of liquid. This is not a fault, it is physics, and the answer is to turn the wattage down or pause between draws. For most adult smokers switching from cigarettes, a modest setting is both more satisfying and more economical.

Flavour Profile and What Liquids Suit It

The kit itself has no flavour. What you taste comes entirely from the e-liquid, so the useful question is how well the hardware reproduces the liquid you put in it. Mesh coils generally do this well. The wide heating surface vaporises liquid evenly, which tends to give a cleaner, rounder flavour than older round-wire coils, and it handles subtle notes such as tobacco blends, tea and light fruits without flattening them.

Some practical liquid guidance for this device:

• Fruit and ice liquids. These suit the Nunchaku 2 well. Cooling agents stay crisp, and tart or juicy profiles come through clearly at mid-range wattage.
• Tobacco and nutty liquids. Lower wattage brings out their dry, warm character. Turn the output too high and delicate tobacco notes can turn harsh.
• Dessert, custard and sweet liquids. They taste rich, but sweeteners caramelise on the coil and shorten its life. If you vape these daily, plan on changing coils more often.
• Menthol and mint. Both work well, though strong menthol can feel sharper at higher wattage.

A 50/50 PG/VG or 60/40 liquid gives a sound balance of flavour and wicking in a small pod. Liquids with a very high VG ratio are thicker and can wick slowly, particularly through a brand-new coil. If you see dry hits or a scorched taste with a thick liquid, try a thinner one before blaming the coil.

Flavour fades as a coil ages, and it usually does so gradually. The first signs are a slightly muted taste, then a faint toasted note, then a clear burnt flavour. When you notice the first of these, change the coil rather than pushing through. A fresh coil restores the original taste immediately.

The five variants on this page differ only in finish, so none of them changes how liquid tastes. If you want to change flavours between sessions, rinse or swap the pod rather than topping up with a different profile. Mixing flavours in one pod is possible, but the result can be muddy, and a coil soaked in one liquid carries ghost notes into the next. Pick a flavour, vape it through, then change cleanly.

Battery Life and Charging

The Nunchaku 2 uses a built-in rechargeable lithium battery. Uwell rates the cell at roughly 1,100 mAh, though you should confirm the exact figure in the specification table on the listing, because it is the number that governs everything else in this section. Because the battery is sealed inside the body, you cannot swap cells. Charging is by USB-C, which is now the standard connector on virtually every phone and tablet, so you will probably already own a cable.

Here is a simple way to turn that capacity into real-world expectations. A 1,100 mAh cell at a nominal 3.7V stores a little over 4 watt-hours. A three-second puff at 25W uses roughly 0.02 watt-hours. Allowing for efficiency losses, that works out at somewhere in the region of 150 to 250 puffs per charge at 25W, and considerably more at lower wattages where the draw is gentler. In practice:

• Light to moderate use at low wattage: a full day, often with charge to spare.
• Mid-range wattage: most of a day for a moderate vaper, with a top-up charge in the evening.
• High wattage and heavy use: you will want to charge mid-day or carry a power bank.

Charging time depends on the adapter and cable. Allow roughly an hour to an hour and a half for a full charge from a decent 5V wall adapter. Charging from a computer USB port is slower. Do not use a fast-charging adapter in a mode that negotiates higher voltages unless the device is designed for it, and always use the cable supplied or a quality replacement.

A few battery care habits help it last for years rather than months.

• Do not leave the device charging overnight on a soft surface like a bed or sofa.
• Avoid letting it sit at zero percent for weeks. Charge it every so often even if you are not using it.
• Keep it away from heat. A hot car in summer is one of the quickest ways to degrade a lithium cell.
• If the casing swells, the device becomes unusually hot or you smell something odd, stop using it and do not charge it.

When the battery finally reaches end of life, do not put the device in your household bin. Lithium batteries cause fires in bin lorries and recycling plants. Take it to a retailer that offers vape and battery take-back, or to a household waste recycling centre drop-off point for small electricals.

Coil and Mesh Technology

The coil is where the Nunchaku 2 earns its flavour and vapour. Instead of a thin round wire wrapped around a cotton wick, a mesh coil uses a flat, perforated sheet of resistance metal pressed against cotton. This has a few real consequences for how the device behaves.

• More surface area. The mesh touches far more of the wick than a round wire does, so liquid is heated across a wide area rather than along a thin line.
• Faster, more even heating. The coil reaches working temperature quickly and stays consistent between puffs.
• Better flavour definition. Even heating avoids hot spots that scorch part of the liquid while the rest stays cool.
• Lower hot-spot risk. Fewer dry hits when the wick is properly primed.

Pod coils in this class typically sit somewhere between about 0.6 and 1.2 ohms. A lower-resistance coil draws more power from the battery and suits higher wattage with a more open airflow, while a higher-resistance coil suits lower wattage, tighter draws and nicotine salt liquids. Check which resistance comes with your kit and which replacement options exist, and match your wattage to the range printed on the coil or pod. Running a coil far above its recommended range shortens its life and risks a burnt taste.

Uwell's coils for this pod format are proprietary, so you must buy compatible Uwell parts. Coils from other brands will not fit, and fakes sold at suspiciously low prices are a genuine problem. Buy from a reputable UK retailer and avoid unbranded marketplace listings.

Priming is the step most people rush. A new coil arrives dry. Fill the pod, close the fill port, then let it sit for five to ten minutes so the cotton soaks right through. Take two or three short draws without pressing the button before you fire it up. Skipping this is the cause of most burnt first puffs and many coils that are written off as faulty.

Coil life depends on what you vape and how you set the device. Expect roughly one to three weeks with typical use, longer with unsweetened liquids and moderate wattage, shorter with sugary liquids and high wattage. Replace the coil when flavour dulls or tastes toasted.

Choosing the Right Nicotine Strength in the UK

UK law caps nicotine e-liquid at 20mg/ml (2%), and this limit applies to refillable e-liquid as well as to the single-use products that are now banned. In practice, the strength you choose should depend on how you vape, not just how much you used to smoke. There are two main types of liquid, and each pairs with a different style of device setting.

• Nicotine salt liquids (often 10mg or 20mg). These deliver nicotine smoothly at the cost of a lower throat hit, and they suit low-wattage, tight mouth-to-lung vaping and higher-resistance coils.
• Freebase liquids (typically 3mg to 12mg). These have a stronger throat hit at a given strength and are used with higher wattage and airier draws, where more vapour is inhaled with every puff.

As a rough starting guide, not medical advice:

• Heavier smokers (around 20 or more cigarettes a day): a 20mg salt at lower wattage, or a 10mg to 12mg liquid if you prefer a gentler hit. Many people find 20mg salt harsh and settle on 10mg.
• Moderate smokers: 10mg salt, or 6mg to 9mg freebase at mid-range wattage.
• Light smokers or social smokers: 5mg to 6mg salt, or 3mg freebase.
• Former smokers reducing intake: step down gradually, for example 10mg to 6mg to 3mg, rather than jumping straight to zero.

Remember that wattage and nicotine interact. The higher you set the output, the more vapour and the more nicotine you inhale per puff. A strength that feels comfortable at low wattage can feel overpowering at 40W. If you push the output up, lower the nicotine strength.

If you use nicotine-free shortfill bottles and add shots yourself, do the maths carefully. A 10ml 18mg shot added to a 50ml shortfill in a 60ml bottle gives roughly 3mg/ml. Always follow the instructions on the bottles.

If you feel dizzy, nauseous or get a persistent racing heart, you are taking in too much nicotine. Stop, drop to a lower strength or lower wattage and speak to a pharmacist or your GP if symptoms persist. Local stop-smoking services can also help with a plan to cut down.

Who the Nunchaku 2 Is For, and Who Should Skip It

No single kit suits everyone. The Nunchaku 2 makes sense for some adult vapers and is the wrong choice for others, and it is better to know which group you fall into before buying.

It is a good fit if you:

• Are an adult smoker moving to vaping and want a device you can adjust as your preferences settle, rather than one locked to a single output.
• Have used a basic pod system and want more battery, more control and a fuller flavour from a mesh coil.
• Prefer a draw that you can tighten or open up, depending on your mood and your liquid.
• Want a refillable device that costs less to run than repeatedly buying single-use products, now that disposables are off the shelves.
• Are comfortable with a few minutes of learning: priming, filling, checking the coil.

It is probably not for you if you:

• Want the smallest possible device. A slimmer pod system is easier to carry.
• Want something you never have to refill or maintain. A refillable device needs a little attention, and pods and coils wear out.
• Are a very heavy cloud chaser. A 2ml pod and a battery of this size will not keep up with sustained high-power vaping.
• Do not currently smoke or vape. Nicotine is addictive and there is no benefit to starting.
• Are under 18. It is illegal to sell vaping products to you, and we will not.

For new vapers, one useful rule is to start with the simple end of the settings. Set the wattage low, pick a salt nicotine liquid at a moderate strength and a flavour you already enjoy, and give yourself a week to adjust. Many people who give up after a day or two do so because they started at a high wattage with a harsh liquid. The Nunchaku 2 rewards patience, and the adjustability that makes it flexible is also why it can feel overwhelming if you change several things at once.

If you have a medical condition, are pregnant or take regular medication, speak to a healthcare professional about nicotine before switching.

How to Use the Nunchaku 2: Filling, Priming and Everyday Operation

Getting a clean start makes everything else easier. Follow these steps the first time, then they become second nature.

• Charge first. Plug the device in and let it charge before the first use. A full first charge also lets you check that the cable and adapter work.
• Remove the pod. Lift it out, peel off any protective film and check the coil is seated.
• Open the fill port. Pull back the silicone bung and fill slowly with the bottle tip angled against the side of the opening, so liquid runs down smoothly instead of bubbling.
• Do not overfill. Stop at or just below the maximum line. Overfilling forces liquid into the airflow channel and causes leaks.
• Close the port fully. Press the bung down firmly all the way round.
• Prime. Wait five to ten minutes, then take two or three gentle draws without firing.
• Seat the pod. Push it into the device until it clicks.

Day-to-day operation depends on the controls described in the manual. Uwell devices commonly use a set number of quick presses of the fire button to switch on, switch off or lock the device, and separate controls to raise or lower the wattage. Check the manual for the exact pattern on your unit, because it is easy to guess wrong and think the device is broken. Lock the device in your pocket so it cannot fire by accident.

Some habits that keep the kit trouble-free:

• Refill before the pod is completely empty. Running a coil dry is the fastest way to burn it.
• Take steady, moderate draws. Chain vaping drains the wick faster than it can refill.
• Wipe the mouthpiece and the pod contacts occasionally with a dry cloth.
• Store the device upright when you can, so liquid stays at the coil and not in the airflow channel.
• Keep e-liquid bottles and the device out of reach of children and pets. Nicotine is toxic when swallowed.

Change the pod or coil when flavour fades, when the liquid turns dark and syrupy or when you start to see a burnt taste. A fresh coil costs a small amount compared with the frustration of fighting a tired one. Between liquids, empty the pod, rinse it with cool water, dry it fully and refill. Never rinse the device body or the contacts with water.

Troubleshooting Common Problems

Most problems with a pod mod have simple causes. Work through the likely ones before assuming a fault.

Leaking or sticky device. The usual causes are an overfilled pod, an incompletely seated fill bung, a pod that has not clicked home or a coil that is flooded. Empty some liquid, reseat the bung and the pod, wipe the device and keep it upright. Leaks also increase after temperature or pressure changes, so be careful in hot cars and on flights.

Gurgling or spitting. Excess liquid in the airflow channel. Blow gently through the mouthpiece with the pod out, or wipe the channel, and try a lower fill level.

Dry or burnt hits. Typical causes are an under-primed coil, a pod that is nearly empty, a liquid that is too thick, wattage set too high or a worn-out coil. Refill, prime again, lower the wattage and if the burnt taste persists change the coil.

Weak flavour. Either the coil is ageing, you have swapped liquids without cleaning the pod or you are vaping a heavily sweetened liquid. Replace the coil first, then try a fresh bottle.

No vapour or no firing. Check the device is switched on and unlocked, the battery is charged, the pod is properly seated and the contacts are clean. If a message indicates a short circuit or no pod, reseat the pod and, if needed, try another one to rule out a faulty coil.

Battery will not charge. Try a different cable and a different adapter, then clean the USB-C port with a dry wooden toothpick, taking care not to bend the contacts. If it still fails, contact us.

Device feels hot. Brief warmth is normal at high wattage. If the body is uncomfortably hot, stop using it, let it cool away from flammable material and do not charge it until it returns to normal temperature. Contact us if it recurs.

Recycling and disposal. When the device or coil reaches the end of its life, do not bin it. Vapes and their batteries are covered by waste electrical rules, and retailers that sell them are expected to offer a take-back option. Used pods, coils and empty bottles can also go to household waste recycling centres that take small electricals. Drop-off points in supermarkets and high streets are an easy option.

Value for Money and Honest Comparisons

Judging value on a refillable kit means looking at three things: the upfront price, the running cost and how long the hardware lasts. The Nunchaku 2 asks for more upfront than a basic starter pod, but its running costs are modest. You pay for e-liquid and a replacement coil or pod every one to three weeks. Compared with the old pattern of buying a new disposable every few days, a refillable kit works out cheaper for most regular vapers within the first month or two, and it produces far less waste.

How does it stack up against other popular choices? Here is a fair read, with the caveat that specifications shift between releases.

• Vaporesso XROS series. These are slimmer, simpler and usually cheaper, aimed at mouth-to-lung vaping with fixed or limited settings. They suit someone who wants minimal fuss. The Nunchaku 2 gives you more battery and a wider wattage range, in exchange for extra size.
• Uwell Caliburn range. The same brand's slimmer pod systems. They are easier to carry and simpler to run, while the Nunchaku 2 is the step up for those who want adjustability.
• Voopoo Vinci family. Similar in concept, with adjustable output and a pod-mod format. The choice often comes down to ergonomics, the pod design you prefer and the coil range available near you.
• SMOK Nord and Novo ranges. Long-established lines with good coil availability. Some are tuned more for sub-ohm style vaping, so check what suits your draw style.
• Geekvape Aegis-type devices. These emphasise ruggedness and splash resistance. If you work outdoors or on a building site, that may matter more than slim lines.

None of these is universally better. The right choice is the one that suits your draw, your pocket and the coil supply you can reach.

On balance, the Nunchaku 2 offers solid value if you want adjustable power, a mesh coil and a battery that gets through a normal day, without the bulk or maintenance of a full tank mod. Its limits are a 2ml pod, a proprietary coil range and a size that is bigger than the slimmest pods. If those limits do not bother you, it is a sensible, well-rounded purchase. If they do, one of the alternatives above may fit better.

Buying from a UK stockist also protects you from counterfeits, gives you access to returns and support, and makes sure age checks and UK-market specifications are respected.
