The Caliburn series sits at the top of what gets asked about most often at the KandyVape counter in Mohammadpur. The question is almost never just “how much?” It is usually three questions layered together: how much for an original, which of the four or five models actually fits what I need, and how do I know the one I am holding is real? This guide answers all three, in that order, for adult smokers and existing vapers in Dhaka and greater Bangladesh.
No prices in this guide are invented. Where KandyVape stocks a model, the current listed price is on the product page. Where we reference a spec, it traces to Uwell’s own published data.
The Uwell Caliburn line currently active in Bangladesh includes the Caliburn G3 (900 mAh battery, 2.5 ml pod, max 25 W, coils at 0.6Ω, 0.9Ω, and 1.2Ω), the Caliburn G4 Mini (1,100 mAh, 3 ml pod, max 35 W, GPP cartridge platform), and the Caliburn G5 (1,600 mAh, 3 ml pod, max 35 W, GPP Alpha cartridge, coils available at 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω). All are closed-system pod devices using USB-C charging. Authentic units carry a scratch-off verification code verified at myuwell.com/verify. Current BDT prices are listed on the KandyVape product page.
Understanding the Caliburn G Series Before You Pick One
Uwell has released so many Caliburn variants that the names blur together on a quick search. The Caliburn A series, the G series, the GK, the X, the G3 Lite, the G3 Pro, the G4 Mini, the G5. Not all of these are relevant to a buyer in Bangladesh today, and not all of them share the same coil ecosystem. The ones that matter for a 2026 purchase decision at a legitimate retailer are the G3, the G4 Mini, and the G5. Everything else is either discontinued, superseded, or outside the import window for the Bangladesh market.
The practical distinction between these three models is straightforward once you understand that Uwell runs them on two different pod platforms. The G3 uses its own G3 Integrated Coil Cartridge. The G4 Mini and G5 both run on Uwell’s GPP platform, which means the replacement pods for both of those devices come from the same cartridge family. This matters at the counter when you come back for replacement pods. A customer who owns a G4 Mini and asks for “Caliburn pods” without specifying GPP will sometimes receive G3 cartridges that physically fit the device but come from the wrong platform and may not seat correctly in every production run. State the model name when ordering pods.
The Three Models, Spec by Spec
The table below pulls only from Uwell’s official product pages. Every number here is checkable.
| Specification | Caliburn G3 | Caliburn G4 Mini | Caliburn G5 |
| Battery | 900 mAh | 1,100 mAh | 1,600 mAh |
| Pod capacity (INT) | 2.5 ml | 3 ml | 3 ml |
| Max output | 25 W | 35 W | 35 W |
| Activation | Button + auto | Auto | Auto + triple-tap |
| Coil platform | G3 Integrated | GPP | GPP Alpha (also GPP compatible) |
| Coil resistances | 0.6Ω, 0.9Ω, 1.2Ω | 0.6Ω (kit) / full GPP range | 0.4Ω, 0.6Ω, 0.9Ω, 1.2Ω |
| Charging port | USB-C (2A) | USB-C | USB-C |
| Refill | Side (standard kit) | Top refill | Side + top options |
| Draw style | MTL to loose RDL | MTL to loose RDL | MTL to loose RDL |
The G3 is the entry point. Nine hundred mAh is a full day for most moderate users, and 25 W is enough for salt nicotine at 0.9Ω or 1.2Ω without any thermal stress on the pod. The ceiling is lower than the newer models, but for a smoker switching to vaping, 25 W at a higher resistance is exactly the right range. The G4 Mini trades a compact form factor for a battery upgrade and the newer GPP cartridge platform. It runs up to 35 W but the 0.6Ω kit pod works best in the 20 W to 28 W window. The G5 is the longest-battery device of the three at 1,600 mAh, with the GPP Alpha cartridge technology and wattage adjustment that runs the full 35 W when the coil resistance and liquid choice support it. Uwell rates the G5 battery at up to six days of typical use, based on their lab testing conditions.
The prop that the GPP Alpha cartridge uses for the G5 is described by Uwell as their AlphaCore longevity technology, which they rate at up to 17 or more refills per pod. What Uwell’s own data page says is that this figure is based on the 0.6Ω, 3 ml pod under laboratory test conditions. Real lifespan varies based on your wattage setting, how frequently you draw, and whether you let the pod run close to empty before refilling, which accelerates dry-hit damage to the cotton.
Which Resistance for Which Liquid
This is the question that causes the most expensive mistakes, because getting it wrong is not fixable once you have poured liquid into a pod and drawn on it several times.
The three resistances available in the G3 platform (0.6Ω, 0.9Ω, 1.2Ω) map to different liquid types and draw preferences. The 1.2Ω coil is the tightest draw and runs the lowest wattage. At that resistance, salt nicotine in the 20 mg to 50 mg range is the correct pairing. The throat hit from salt nic at high resistance is smooth because the lower power and slower vapour delivery keep the nicotine delivery gradual. Run 50 mg salt nicotine through a 0.6Ω coil at 20 W to 25 W and the hit is sharp to the point of being uncomfortable for most people. The 0.6Ω coil is built for freebase nicotine in the 3 mg to 6 mg range, or for lower-strength salt nic (12 mg or below) where the looser, faster draw is the point rather than a problem.
The NIH’s PubChem database entry for propylene glycol and for vegetable glycerin (glycerol) are worth reading if you want the base-chemistry context for why VG/PG ratio affects vapour density and throat hit alongside nicotine level. Higher VG (70/30 or above) is thicker, produces more visible vapour, and suits lower-resistance pods better because the coil needs more heat to wick the viscous liquid. Higher PG carries flavour more efficiently and wicks faster in tighter coils.
For the G4 Mini and G5 on GPP cartridges: the 0.6Ω pod is the most versatile general-purpose option at moderate wattage (18 W to 28 W). The 0.9Ω is the crossover option for users who want a tighter draw than the 0.6Ω provides but more battery efficiency than running at high wattage. The 1.2Ω works well with salt nicotine and a tighter MTL draw.
| Coil | Wattage window | Nicotine type | Draw style |
| 0.4Ω (G5/GPP only) | 25 W to 35 W | Freebase 3 mg to 6 mg | Loose RDL |
| 0.6Ω | 18 W to 28 W | Freebase 3 mg to 12 mg, or salt 12 mg to 20 mg | Loose MTL to tight RDL |
| 0.9Ω | 12 W to 20 W | Salt nic 20 mg to 35 mg | MTL |
| 1.2Ω | 8 W to 15 W | Salt nic 35 mg to 50 mg | Tight MTL |
These are operational ranges, not guarantees. Your preferred wattage within a range depends on your draw speed, how warm you want the vapour, and how aggressive the specific liquid’s throat hit is. Start at the lower end of the wattage range for a new pod and increase only if the draw feels thin.
The Authenticity Problem in Bangladesh and How to Solve It
The Caliburn series is one of the most cloned pod systems available. This is not speculation. Uwell themselves maintain a dedicated verification page because the counterfeiting volume across Asian markets is high enough to justify the infrastructure. In Bangladesh, the problem is compounded by the informal import structure: units arrive through unofficial channels, are repackaged or reboxed in some cases, and are listed at a price low enough to undercut formal retail.
Here is what a fake Caliburn typically gets wrong, in order of how easy each is to spot:
The scratch-off verification code fails. Every genuine Uwell device ships with a security label on the box. Scratch the coating off the printed area and you will reveal a code. Go to myuwell.com/verify, enter the code without spaces or dashes, and the page will confirm whether it is a valid, authentic product code. A clone either has no code, has a code that has already been used and reports as invalid, or has a code that never existed in Uwell’s database. This is the single most reliable check and it takes thirty seconds.
The USB port is wrong. All current G3, G4 Mini, and G5 devices use USB-C. A micro-USB port on a device sold as a current Caliburn model is an immediate counterfeit indicator. Check the port shape before accepting the unit.
The coil resistance reading is off. If you have a coil resistance checker or your device displays the coil ohms, compare the reading to the number printed on the pod. Genuine Uwell coils fall within a tight manufacturing tolerance. A fake coil frequently measures 0.2Ω to 0.4Ω away from the printed value. That difference is not cosmetic. It changes the wattage the chipset delivers and the temperature the cotton reaches.
The print quality on the body and packaging is inconsistent. Genuine units have crisp, evenly-applied silkscreen or laser etching. Check the UWELL wordmark and the Caliburn branding on both the device body and the box. Blurred characters, uneven ink saturation, or font weight differences from the official product photography are warning signs.
The weight is lighter than expected. Clones frequently use cheaper internal components and thinner frame materials. The G3, for example, weighs approximately 47 g to 48 g per Uwell’s spec sheet. A substantially lighter device warrants scrutiny.
We stock authentic Caliburn units at KandyVape because counterfeit hardware is a customer service disaster that cannot be resolved after the fact. You can check the code on the box of any unit we sell against Uwell’s verification system before you complete the purchase, in person at Shop 22, Level 3, Sahabuddin Plaza, Adabar, Mohammadpur, or by requesting the code via our order channels before dispatch.
Grey-Market Price Gaps: What They Mean
A Caliburn G3 appearing on an informal listing at significantly below authorised retail price is not a deal. It is either a clone, a used unit being resold, or a unit sourced through import channels that carry no authenticity guarantee and no manufacturer accountability. The gap between that price and what a verified retailer charges represents the cost of knowing the device is real, the coil resistance matches what is printed on the pod, and the chipset will not fail during a charge cycle.
We will not tell you that grey-market sellers never sell authentic units, because some occasionally do. What we will tell you is that you cannot verify that claim without the scratch-code check, and some informal sellers will not provide a code because the box has already been opened or is missing entirely. There is also a straightforward consideration for Bangladesh buyers specifically: if a device fails inside a week and it came from an informal channel, the seller is gone.
The Tobacco Control Laws database entry for the Smoking and Tobacco Products Usage (Control) (Amendment) Act 2026 confirms that e-cigarettes are not banned under the current gazetted law in Bangladesh. Purchase and use by adults is legal. The regulatory context is relevant because it affects what retailers can legitimately import and sell, which in turn affects whether an informal importer is operating inside or outside the law when bringing stock in.
Logistics: How to Order and What to Expect
KandyVape dispatches orders daily at 3:00 PM, including weekends. Orders confirmed before 3:00 PM on any day go out the same day. Orders received after 3:00 PM dispatch the following day. Free shipping applies on orders of 3,500 BDT and above. Delivery charges below that threshold are listed on the shipping information page.
If you are in Mohammadpur or nearby, the physical shop at Shop 22, Level 3, Sahabuddin Plaza, Adabar, Mohammadpur 1207, Dhaka lets you examine the unit, run the code check in front of staff, and confirm the pod type before any money changes hands. For the Caliburn specifically, where coil resistance and platform compatibility are the two most important variables in a buying decision, handling the device first is worth the trip if you are unsure.
KandyVape operates a strict no-return, no-refund policy on all products. The detail on that policy is on the policy page.
This is also why this article is as detailed as it is. A wrong coil specification here is not a content problem. It is a customer paying for a replacement pod that does not fit their device, with no way to send it back.
FAQ
Q1: What is the price of the Uwell Caliburn G3, G4 Mini, and G5 in Bangladesh?
Current BDT prices for each model are listed on the individual product pages at KandyVape. We do not publish prices in article content because inventory and market pricing change and an outdated price in a guide article causes more confusion than no price at all. The product page shows the current and accurate figure.
Q2: Are Caliburn G3 pods compatible with the G4 Mini?
Within the broader G Pod Platform, Uwell confirms cross-compatibility between G3 integrated cartridges and GPP cartridges on G-series devices. Practically, GPP cartridges fit G3 devices and G3 cartridges can be used in GPP-platform devices. However, the default replacement pod for the G4 Mini is the GPP cartridge, and the G3’s own integrated coil cartridge is the correct ongoing replacement for a G3. When ordering replacement pods, specify your exact model and the pod series to confirm you are receiving the right cartridge. If you are uncertain, contact us before ordering.
Q3: How do I know if a Caliburn I am looking at is genuine?
Scratch the security label on the box to reveal the verification code, then enter it at myuwell.com/verify. A genuine unit returns an authentication confirmation. Also check that the charging port is USB-C (not micro-USB), that the body print quality matches official product photography, and that the device weight feels consistent with the spec sheet. These four checks together give a strong indication of authenticity.
Q4: What nicotine strength should I use with a Caliburn?
This depends entirely on the coil resistance in your pod. The 1.2Ω pod works with salt nicotine in the 35 mg to 50 mg range and gives a tight MTL draw similar to a cigarette draw. The 0.9Ω pod suits salt nic in the 20 mg to 35 mg range. The 0.6Ω pod is intended for freebase nicotine at 3 mg to 6 mg, or lower-strength salt nic at 12 mg to 20 mg. Running high-strength salt nicotine through a low-resistance coil produces a throat hit that is harsh enough that most people discontinue the device within days.
Q5: How long does a Caliburn pod last?
Pod lifespan varies considerably depending on how frequently you use the device, what wattage you run, whether you allow the liquid level to drop very low before refilling, and the VG/PG ratio of your liquid. There is no single honest figure to give here. Uwell rates the GPP Alpha cartridge in the G5 at up to 17 or more refills under their laboratory conditions on the 0.6Ω pod. Real-world usage at higher wattage with thick liquids will shorten that. Running a pod nearly dry before refilling causes dry-hit damage to the cotton that permanently degrades the coil. Treat the pod lifespan figure as a best-case reference, not a guarantee.
Q6: When will my order arrive if I order today?
KandyVape dispatches daily at 3:00 PM, including weekends. Typical delivery windows and charges outside the free shipping threshold are listed on the shipping information page. Confirm dispatch timing with the order channel for your specific location.
Q7: What happens if the device does not suit me after I receive it?
KandyVape operates a strict no-return, no-refund policy on all products. This is stated clearly on the policy page and in our order process. The practical consequence is that the choice of model, coil resistance, and nicotine type needs to be correct before you order. This guide exists to help you make that call accurately. If you are unsure between two models or two coil options, contact us before ordering. Our staff can walk through the compatibility question with you in advance.
What to Do Before You Order
Check the specification table in this guide against the device you intend to use. If you already own a Caliburn G3, the replacement pod you need is the G3 Integrated Coil Cartridge in the resistance that matches your current draw preference. If you own a G4 Mini or G5, the replacement is the GPP or GPP Alpha cartridge respectively. If you are buying your first device, the G3 is the appropriate entry point for most switchers who want MTL performance with salt nicotine; the G5 is the right choice if battery life between charges is the primary concern.
If any specification in this guide does not match what is printed on your device or on the pod packaging, trust the printed value. Never assume compatibility; confirm it first, especially if you cannot return the product after purchase.
