The number on the box is 30,000 puffs. That figure is real, but it applies to one specific operating mode under one specific set of conditions. Most users will not see 30,000 puffs. Some will see fewer than half that. Whether the CD30000 is worth 600 BDT depends entirely on understanding why, and this review covers the mechanics of that question in full.
The Upends CD30000 is a rechargeable disposable vape with 20 ml of pre-filled 50mg salt nicotine e-liquid, an 850 mAh battery, and dual mesh coils rated at 1.1Ω each. It offers up to 30,000 puffs in Soft mode, 25,000 in Norm mode, and 20,000 in Boost mode, with a draw-activated mechanism and adjustable airflow that supports both MTL and DTL draws. It is currently listed at 600 BDT on the KandyVape product page. All specs verified against the official Upends manufacturer page.
The Puff Count Question: What 30,000 Actually Means
Puff count figures on disposable vapes are calculated under standardised laboratory conditions: a fixed draw duration, typically one to two seconds, at a fixed interval. Your actual draw may be longer. You may take three or four puffs in a row. You may run the device in Boost mode because you want a stronger hit. Each of those variables reduces the total count below the advertised maximum.
The CD30000 gives you three modes and three corresponding puff estimates. Soft mode is the manufacturer’s 30,000-puff claim and runs the coil at its lowest output, producing lighter vapour and a gentler throat hit. Norm mode is rated at approximately 25,000 puffs and sits in the middle: reasonable vapour production and a noticeable hit. Boost mode is rated at approximately 20,000 puffs and delivers the most vapour and the most pronounced nicotine delivery per puff.
A user who smokes twenty cigarettes a day and switches to the CD30000 will typically take between 150 and 300 puffs per day, depending on their draw length and frequency. At 200 puffs per day in Soft mode, the device’s 30,000-puff capacity represents roughly 100 to 150 days of use. At 200 puffs per day in Boost mode, that drops to roughly 70 to 100 days. Those are broad ranges because draw behaviour varies significantly between users.
The screen helps with this. The CD30000’s 3D curved display shows the remaining puff count in real time, so you are not guessing. When the count approaches zero, the e-liquid is exhausted. This is genuinely useful, because it removes the guesswork that comes with an opaque tank and means you can plan around the device’s lifespan rather than being caught by a dead device mid-day.
One caveat the manufacturer does not prominently advertise: the 850 mAh battery will need recharging before the e-liquid runs out. An 850 mAh built-in battery is adequate for a day of normal use but will not sustain week-long use without a USB-C top-up. The device ships without a charging cable included, so plan to use a cable you already own. The charging input rate is not published on the official Upends specification page; check the printed information inside the device packaging for the specific current rating.
The Dual Mesh Coil Configuration and the 50mg Nicotine Pairing
The CD30000 uses two 1.1Ω mesh coils running in parallel. This is a specific design decision worth understanding before you buy.
At 1.1Ω per coil, the individual resistance is above the sub-ohm threshold. Mesh coils at this resistance level are optimised for salt nicotine, and the CD30000’s pre-filled 50mg salt nicotine e-liquid pairs correctly with this configuration. The draw profile in MTL (mouth-to-lung) mode, with the airflow slider closed down, will replicate the resistance of a cigarette draw more closely than an open-airflow DTL (direct-to-lung) setup. For a smoker switching from cigarettes, this matters. Start with airflow restricted toward MTL and Soft or Norm mode. The Boost mode on fully open airflow produces significantly more vapour and delivers nicotine faster. For someone who has been smoking for years, this pairing can feel overwhelming on the first use.
The dual coil setup provides more even heat distribution across the liquid than a single coil, which is why consistent flavour delivery across the tank’s lifespan is a feature Upends highlights. The first third and the last third of a single-coil disposable often taste noticeably different as the wick dries unevenly. The parallel mesh arrangement mitigates this, though it does not eliminate it entirely. As the e-liquid level drops below roughly 20 to 30% (watch the screen indicator), you may notice a slight change in vapour density as the coil begins drawing from a shallower pool.
According to the UK Office for Health Improvement and Disparities’ 2022 evidence review on nicotine vaping, pharmacokinetic studies indicate that nicotine delivery from vaping products varies significantly by device type, e-liquid nicotine concentration, and the salt versus freebase formulation. The OHID review notes that salt-based nicotine formulations are absorbed faster into the bloodstream than freebase nicotine and produce a smoother throat hit at high concentrations. KandyVape does not assert any health outcome from this: we are reporting what a named public health body found.
Mode Selection: A Practical Guide
The three modes are not simply “low, medium, high.” They represent different use cases.
Soft mode is the right starting point for anyone switching from cigarettes. The lower output means the nicotine delivery is slower and the throat hit is milder. For a one-pack-a-day smoker switching for the first time, starting in Soft mode reduces the risk of an overwhelming first experience that sends them straight back to cigarettes. It also maximises the device’s lifespan, which means more value from the 600 BDT purchase.
Norm mode is the middle ground. Most adult vapers who have some experience with pod devices settle here after a week or two. The hit is satisfying without being excessive, and at 25,000 puffs, the lifespan is still substantial.
Boost mode is for vapers who know what they want: dense vapour, a stronger hit, and higher nicotine delivery per puff. At 20,000 puffs, the capacity is one-third lower than the headline claim. If you run this device exclusively in Boost mode from day one, you are not buying a 30,000-puff device. You are buying a 20,000-puff device at the same price, which is still a respectable figure.
The mode is changed by pressing the single button. The screen shows the active mode and updates in real time as you switch. You do not need to hold or double-press; a single press cycles through the modes. This is confirmed on the Upends official product page.
| Mode | Puff Count (Manufacturer) | Use Case | Nicotine Delivery per Puff |
| Soft | Up to 30,000 | First-time switchers, low-intensity use | Lower |
| Norm | Up to 25,000 | Experienced vapers, standard daily use | Moderate |
| Boost | Up to 20,000 | High-output preference, dense vapour | Higher |
All puff counts are manufacturer-rated under standardised conditions. Actual counts will vary based on draw length, frequency, and individual puffing behaviour.
The Screen: What It Shows and Why It Matters
The 3D curved display is the CD30000’s most distinctive feature. This is not a novelty. It is a functional tool that addresses one of the most common complaints about high-capacity disposables: not knowing how much e-liquid or battery life remains.
The screen displays four data points: battery level, e-liquid level, puff count remaining, and active mode. These update in real time. The galaxy light effects that flash during each puff are an aesthetic feature; they are independent of the functional display data.
One practical point: the curved screen means the display reads slightly differently depending on the angle you hold the device. Hold it straight at eye level for an accurate read of the percentage figures. When you order, visually confirm that the screen activates on the first draw and that all four data points display.
A non-functional or static screen on delivery is a red flag for a clone unit, which we address in the next section.
Authenticity Verification: The Specific Steps for Bangladesh Buyers
The CD30000 is a visually distinctive device, which makes it a target for cloning. In the Bangladesh market, clone disposables enter through grey-market supply chains and are sometimes listed at slightly lower prices than genuine units. The price difference rarely exceeds 100 to 200 BDT, and it is not a saving when the device is counterfeit.
Upends operates an official authenticity verification portal at upends.com/pages/verification. The process works as follows: the authentic device packaging carries a scratch-off panel that conceals an anti-counterfeiting code. Scratch the panel, reveal the code, and enter it at the verification portal. A genuine unit will return a confirmed result. A code that returns an error, a “code already used” result, or no result at all indicates a problem with the unit.
What clones of the CD30000 typically get wrong:
Clones replicate the curved outer shell but cannot reliably replicate the functional display. On a genuine unit, the screen shows live, updating data from the first draw. On a clone, the display is often static, shows placeholder values that do not change, or shows a looping animation unrelated to actual device status. If the puff count displayed does not decrease after you take puffs, the screen is cosmetic rather than functional.
A second tell is the scratch-off panel itself. Genuine Upends packaging uses a scratch-off coating that leaves visible metallic residue when removed, similar to a scratch card.
Thin paper stickers, printed codes with no scratch coating, or codes printed directly on the box without a covering layer are inconsistent with genuine Upends packaging.
Inspect the device on arrival at the Mohammadpur shop or immediately on delivery. If the screen does not activate on the first draw, contact us before attempting to use the device further.
means we cannot accept returns after use. This is why we stock the CD30000 from our verified supply chain and why verifying your unit immediately on delivery is worth the sixty seconds it takes.
E-Liquid Chemistry: What You Are Drawing
The CD30000 comes pre-filled with 20 ml of 50mg salt nicotine e-liquid. The VG/PG ratio of the pre-filled e-liquid is not published on the official Upends specification page; check the device packaging for this information if it is relevant to your choice.
Nicotine salt, as distinct from freebase nicotine, uses a benzoic acid compound to lower the pH of the nicotine solution. The practical effect is a smoother throat hit at high nicotine concentrations, which is why salt formulations at 50mg are common in low-to-mid-resistance disposable devices. At 1.1Ω, the coil operates in a range that is appropriate for this nicotine concentration. Running a 50mg salt liquid through a sub-ohm setup below 0.4Ω at high wattage would produce a throat hit that most users find unpleasant. The CD30000’s coil resistance avoids this problem by design.
Propylene glycol (PG), one of the two base solvents common to almost all commercial e-liquids, is classified as generally recognised as safe (GRAS) for food use by the US FDA and is listed on PubChem (CID 1030) as a compound with established safety data in food and pharmaceutical applications. Its function in e-liquid is as a carrier for flavour compounds and nicotine, and it contributes to throat hit. This is a factual description of the chemistry; KandyVape does not make any health claim about the safety of inhaling heated PG aerosol.
Six Flavours Available in Bangladesh
KandyVape currently stocks six flavour variants of the CD30000. These are the flavours available for selection at checkout or at the Mohammadpur counter:
Watermelon Ice delivers a fruit and cooling profile. Sour Apple is a tart, sharp profile. Strawberry Mango is a tropical fruit blend. Grape Ice adds a cooling element to a grape base. Pink Burst is a mixed fruit profile. Xmas Bear is a seasonal festive blend.
Flavour preference is personal and cannot be predicted. If you are switching from cigarettes and have never vaped before, a menthol-adjacent profile such as Watermelon Ice or Grape Ice tends to be an easier transition than a dense fruit profile. This is an observation, not a universal rule.

Who Should Buy This and Who Should Not
Buy the CD30000 if you are an adult smoker or existing vaper who wants a high-capacity disposable with a functional information display, adjustable airflow for MTL or DTL preference, and a verified nicotine delivery in a self-contained package. The three-mode system gives you genuine control over daily nicotine consumption in a way that most fixed-output disposables do not.
Do not buy the CD30000 if you primarily want sub-ohm DTL output with heavy vapour production. The 1.1Ω dual coil configuration is designed for MTL and restricted-DTL use. Fully open airflow in Boost mode produces a competent DTL draw but this device is not a high-wattage DTL system. If you are looking for that profile, is where to look.
Do not buy the CD30000 expecting 30,000 puffs if you plan to use Boost mode regularly. Your real-world count in that mode is up to 20,000 puffs, which is still a substantial figure but is one-third less than the headline claim.
The Bangladesh regulatory landscape for e-cigarettes was clarified by the Smoking and Tobacco Products Usage (Control) (Amendment) Act 2026, gazetted on 10 April 2026, which removed the e-cigarette import prohibition that had been introduced by the December 2025 ordinance. E-cigarettes are not banned under Bangladesh law as of this article’s publication. Adults 18 and over may purchase legally.

FAQ
Q: Is 30,000 puffs a realistic figure for the CD30000?
It is the manufacturer-rated maximum under Soft mode at standardised puff duration. Real-world counts will be lower depending on your draw length, frequency, and which mode you run. A user taking 200 puffs per day in Soft mode can expect roughly 100 to 150 days of use; in Boost mode, that range drops to approximately 70 to 100 days. These are estimates, not guarantees, because individual draw behaviour varies significantly.
Q: What is the difference between Soft, Norm, and Boost modes?
All three modes draw from the same 20 ml of e-liquid and the same 850 mAh battery. Soft mode runs the coil at lower output, producing lighter vapour and the longest total puff count (up to 30,000). Norm mode sits at moderate output with approximately 25,000 puffs. Boost mode runs at the highest output, delivering more vapour and stronger nicotine impact per puff, with approximately 20,000 puffs total. You cycle through modes by pressing the single button; the screen shows the active mode.
Q: How do I verify that my CD30000 is genuine?
Locate the scratch-off panel on the packaging, reveal the anti-counterfeiting code beneath it, and enter the code at the official Upends verification portal at upends.com/pages/verification. A confirmed result indicates a genuine unit. If the code is missing, already used, or returns an error, do not use the device and contact us immediately.
Q: What nicotine strength does the CD30000 use, and is it suitable for a smoker switching from cigarettes?
The CD30000 contains 50mg salt nicotine (5%), which is a high-concentration salt formulation. For an adult smoker switching from cigarettes, this concentration is often appropriate because salt nicotine at this level delivers nicotine quickly and smoothly. We recommend starting in Soft mode with airflow adjusted toward the MTL (mouth-to-lung) position, which most closely replicates the draw resistance of a cigarette. Nicotine is addictive; switching adults should be aware they are maintaining nicotine use, not eliminating it.
Q: When will my order arrive if I order today?
Orders placed before 3:00 PM dispatch the same day, including weekends. Delivery timing within Dhaka and outside Dhaka depends on your location. Check the shipping and delivery page for the current rates and estimated windows by area.
