The XLIM SQ Pro is one of the more capable pod kits OXVA has built. It has a 1,200mAh battery, a genuine colour screen, and works with four different coil resistances across multiple cartridge formats. For someone switching from cigarettes or moving on from a device that let them down, those are real advantages. But the XLIM family has six active members with overlapping names and partially overlapping coil compatibility. Order the wrong replacement pod for this device and you have hardware that cannot perform as intended and cannot be returned. This article exists to prevent that.
The OXVA XLIM SQ Pro is a 1,200mAh pod kit with a 5-30W output range and a 0.96-inch TFT colour screen. It ships with XLIM Top Fill cartridges in 0.6Ω and 0.8Ω, and is compatible with all XLIM series cartridges including XLIM V2, Top Fill, and Prefilled formats in resistances of 0.4Ω, 0.6Ω, 0.8Ω, and 1.2Ω. The recommended wattage for each Top Fill coil is 26-30W (0.4Ω), 20-25W (0.6Ω), 12-18W (0.8Ω), and 10-12W (1.2Ω). It charges via Type-C at 5V/2A. The current price listed on the KandyVape product page is 4,000 BDT.
What You Are Actually Getting: Hardware Breakdown
The XLIM SQ Pro is a square-format pod kit built from zinc alloy, IML plastic, and PCTG. It measures 54.4mm wide, 20.4mm deep, and 77mm tall, and weighs 88g. That weight is not negligible. If you hold a cheap generic pod system daily, the SQ Pro will feel notably heavier. The trade-off is build quality that does not flex when gripped and a screen that is readable in daylight.
The 0.96-inch TFT colour screen is functional rather than decorative. It displays your current wattage, battery level, and puff count in clear text. The device operates in two modes: Smart Mode, which detects the inserted coil and sets an optimal wattage automatically, and Power Mode, which lets you manually set wattage anywhere from 5W to 30W. For a first-time buyer, Smart Mode is the correct starting point. For someone who already knows exactly where they want to run a specific coil, Power Mode gives that control.
Airflow is adjusted via a side slider. The range goes from tight MTL (mouth-to-lung, similar to a cigarette draw) through to a moderately restricted direct-to-lung pull depending on which coil resistance you are running. The 1.2Ω coil used with a tight airflow setting produces the closest approximation to a cigarette draw. The 0.4Ω coil with the airflow fully open produces a warmer, airier direct-to-lung hit that is more relevant for someone who has already been vaping for some time.
The Coil Question: This Is the Section That Matters
The XLIM SQ Pro ships with two XLIM Top Fill cartridges: a 0.6Ω pre-installed in the device and a 0.8Ω in the box as a spare. Both hold 2ml of e-liquid and use a top-fill design that does not require removing the pod to refill. Those two coils cover the device’s most common use cases: the 0.6Ω for freebase nicotine at RDL settings, and the 0.8Ω for nicotine salt at MTL settings.
The device is compatible with a wider range of XLIM series cartridges beyond those two. According to OXVA’s official coil and cartridge specification, the full verified wattage table for cartridges that work in the XLIM SQ Pro is as follows:
| Cartridge Type | Resistance | Wattage Range | Draw Style | Preferred Liquid |
| Top Fill | 0.4Ω | 26-30W | RDL | Freebase |
| Top Fill | 0.6Ω | 20-25W | RDL/MTL | Freebase |
| Top Fill | 0.8Ω | 12-18W | MTL | Nic Salt |
| Top Fill | 1.2Ω | 10-12W | MTL | Nic Salt |
| XLIM V2 | 0.6Ω | 20-25W | RDL | Freebase |
| XLIM V2 | 0.8Ω | 12-18W | MTL | Nic Salt |
| XLIM V2 | 1.2Ω | 10-12W | MTL | Nic Salt |
Run any coil outside its stated wattage window and the result is predictable: at too high a wattage the coil overheats faster than the wick saturates, which produces a dry hit and accelerated degradation. At too low a wattage the coil never reaches proper operating temperature, so vapour production is thin and flavour is muted. Neither outcome is a device fault. Both are avoidable by staying within the wattage window.
The XLIM V2 cartridge is an older design that is also compatible with this device. It is worth noting that the XLIM V2 does not offer a 0.4Ω variant; that resistance only exists in the Top Fill format. If you are upgrading from an older XLIM device and have XLIM V2 pods already, they will work in the SQ Pro at the same wattage ranges shown in the table above.
Nicotine Strength and Coil Pairing: The Mistake Most New Buyers Make
Resistance and nicotine strength need to be matched deliberately. This is not a stylistic preference; it is physics and chemistry. A 0.4Ω coil running at 26-30W creates high vapour volume and heat. Running 50mg salt nicotine through it produces a throat hit that most people cannot tolerate for more than a few puffs. The propylene glycol that carries the nicotine in e-liquid is documented by PubChem (CID 1030) as a substance with known mucous membrane irritation properties, and that irritation is dose- and temperature-dependent. Higher heat and higher nicotine concentration multiply the effect.
The practical matching guide for this device:
- 0.4Ω at 26-30W: 3mg to 6mg freebase nicotine. Not appropriate for 20mg or 50mg salt.
- 0.6Ω at 20-25W: 3mg to 12mg freebase, or lower-strength salt up to approximately 20mg. The exact upper limit depends on the specific liquid’s PG/VG ratio.
- 0.8Ω at 12-18W: 20mg to 50mg salt nicotine. This is the correct coil for a cigarette smoker switching to vaping for the first time. The output is controlled, the draw is tight, and the salt delivery is efficient without being harsh.
- 1.2Ω at 10-12W: 35mg to 50mg salt nicotine. Tightest draw, lowest output, designed for people who want the closest possible approximation to a cigarette.
If you are moving directly from cigarettes and you have never vaped before, start with the 0.8Ω coil and salt nicotine. Start at the lower end of the wattage window, around 12W to 14W, and adjust upward only if the vapour production feels insufficient. Do not start at 18W with 50mg salt.
Battery, Charging, and Day-to-Day Reality
The 1,200mAh battery is larger than the 1,000mAh in the XLIM Pro (rectangular format) by 200mAh. OXVA’s lab data, based on 0.8Ω coil use, puts the figure at roughly three days between charges. That figure should be understood as a range, not a guarantee. OXVA states it as a lab result under specific conditions. Actual battery life varies with coil resistance, wattage setting, draw duration, and frequency of use. A person who draws on the device continuously at 25W will exhaust the battery significantly faster than someone taking short draws at 14W across the same time period.
Charging is via Type-C at 5V/2A. As Battery University’s analysis of lithium-ion charging documents, charging to approximately 70 percent capacity takes only a fraction of the total charge time, with the remainder absorbed more slowly during the saturation phase. OXVA’s stated 45-minute charge time is a manufacturer lab figure based on 0.8Ω testing conditions. In practice, charge time will vary with the state of discharge and ambient temperature. Use the supplied Type-C cable, or a reliable replacement at the same 5V/2A rating. Do not use the device while it is charging.
XLIM SQ Pro vs XLIM Pro vs XLIM SQ Pro 2: How to Tell Them Apart
This causes genuine confusion because the product names differ by only a few characters. Here is what each device actually is:
| Model | Battery | Screen | Form Factor | Kit Coils |
| XLIM Pro | 1,000mAh | 0.42-inch OLED | Rectangular, slim | Top Fill 0.6Ω and 0.8Ω |
| XLIM SQ Pro | 1,200mAh | 0.96-inch TFT colour | Square | Top Fill 0.6Ω and 0.8Ω |
| XLIM SQ Pro 2 | 1,600mAh | 1.09-inch HD touchscreen | Square, slightly larger | Top Fill coils (same series) |
The XLIM Pro and XLIM SQ Pro use the same coil series at the same wattage ranges. The physical difference is form factor and battery size. The XLIM SQ Pro 2 is a different generation with a touchscreen and significantly larger battery; it is a separate purchase decision. If a listing describes an XLIM SQ Pro 2 but the photo shows the non-touch 0.96-inch screen from the original SQ Pro, it is either mislabelled or counterfeit.
Both possibilities matter in the Dhaka market.
Authenticity: What to Inspect Before You Decide to Keep the Device
OXVA has documented that clone XLIM cartridges and devices circulate in markets outside their official distribution network. Per OXVA’s official anti-counterfeit guidance, no third party is authorised to manufacture XLIM-compatible cartridges. Any cartridge marketed as “compatible” but not carrying the OXVA brand is not an authorised product.
For the XLIM SQ Pro kit and its cartridges, here is the specific inspection sequence:
The device box carries a scratch-off anti-counterfeit label. Scratch the protective coating and either enter the code at oxva.com/pages/verify or scan the QR code with your phone camera. Authentic products return a verified result on first use; the code cannot be used twice. If the code returns an error, or if the verification page cannot locate the code, do not proceed with the purchase.
Beyond the verification code, check the following physically. The OXVA wordmark on the device should be sharply printed with consistent character spacing. The zinc alloy body should feel solid, not hollow. The screen should power on immediately when the fire button is pressed five times rapidly. The cartridge connection should seat firmly without play. Clone units frequently have loose cartridge connections that result in poor contact and inconsistent firing.
Grey-market listings in Dhaka at prices noticeably below the authorised range are the primary source of counterfeit risk.
You can check the authenticity code against the manufacturer’s verification page before you buy from anyone, including us. That process takes approximately thirty seconds and eliminates the single largest financial risk in this purchase.
We stock the XLIM SQ Pro at 4,000 BDT. If you are comparing that price against a lower-cost listing elsewhere and wondering why the gap exists, the most common explanations are grey-market sourcing, clone units, or a device without local warranty support.
KandyVape operates a strict no-return, no-refund policy on all products. That policy is why this article goes into this level of detail. A buyer who inspects the verification code on arrival and identifies a problem before opening the cartridge seal has practical recourse; a buyer who discovers a problem two weeks later does not.
What the WHO Has Said (Attributed, Not Our Claim)
We do not make health claims about vaping. What we can do is point to named authorities and let you read what they have concluded. The WHO’s Global Tobacco Epidemic Report 2021, available at who.int, states that e-cigarettes contain nicotine, which is highly addictive and can harm brain development in adolescents. The report also notes that evidence on the long-term health effects of e-cigarettes in adults remains limited and evolving. That is what the WHO has concluded. We are not citing it to argue for or against vaping; we are citing it so you have access to what the relevant authority says rather than relying on retailer claims in either direction.
Every product we sell is intended for adults who already smoke or vape and are making an informed decision about their nicotine use. We do not encourage anyone who does not currently smoke or vape to begin.
First Week: What to Expect
The most common first-week problem with any pod system is a dry hit during the first fill. Prime the coil before firing. With the Top Fill cartridge, fill the pod, replace the cap, and wait five minutes before your first draw. This allows the wick to saturate. A dry hit on a new coil does not necessarily destroy it, but repeated dry hits on an inadequately saturated wick will shorten coil life noticeably.
The second most common problem is choosing the wrong wattage at first. Start in Smart Mode and use the device as OXVA intends before switching to Power Mode. Smart Mode will apply a wattage appropriate for the detected coil. Once you have a baseline for how the device performs, you can move to Power Mode to fine-tune.
Coil life varies considerably with user behaviour. A person taking short, frequent draws on a well-primed coil at mid-range wattage will get a different lifespan than someone who chain-draws at the top of the wattage window. We will not quote a specific number of days because OXVA’s own lab figures are based on controlled conditions that no real user replicates exactly.
What we can say is that sweet or high-VG liquids tend to shorten coil life relative to higher-PG liquids, because thick liquid wicks more slowly and increases the risk of dry spots.

FAQ
What coils are compatible with the Oxva Xlim SQ Pro?
The XLIM SQ Pro accepts all XLIM series cartridges: XLIM Top Fill, XLIM V2, and XLIM Prefilled. Available resistances are 0.4Ω, 0.6Ω, 0.8Ω, and 1.2Ω. The 0.4Ω option only exists in the Top Fill format. The XLIM V2 format does not include a 0.4Ω coil, so if you are ordering V2 pods, your available options are 0.6Ω, 0.8Ω, and 1.2Ω.
Note that XLIM C coils, which exist for the separate XLIM C device, are not compatible with the SQ Pro.
What is the difference between the Xlim SQ Pro and the Xlim SQ Pro 2?
The XLIM SQ Pro has a 1,200mAh battery and a 0.96-inch TFT colour screen operated by physical buttons. The XLIM SQ Pro 2 has a 1,600mAh battery and a 1.09-inch HD touchscreen with a puff diary function. Both use the XLIM Top Fill coil series at the same wattage ranges. They are different generations and are priced differently. If you are looking at a listing and the spec sheet mentions a touchscreen but the device in the photo shows physical buttons, treat that as a red flag.
Which wattage setting should I use with the 0.8Ω coil?
The verified wattage window for the XLIM Top Fill 0.8Ω and XLIM V2 0.8Ω coils is 12W to 18W. Start at 12W to 14W and increase only if you want more vapour output. The 0.8Ω coil is designed for MTL use with nicotine salt. Running it above 18W will accelerate coil wear and produce a harsher hit than the coil is designed for.
How long does the Oxva Xlim SQ Pro take to charge?
OXVA states approximately 45 minutes based on their lab testing using the 0.8Ω coil. That figure is a manufacturer data point under controlled conditions, not a guaranteed real-world result. Charging from a fully depleted battery may take longer depending on ambient temperature and the charger used. The device charges at 5V/2A via Type-C. Use a compatible charger at that rating.
Is this device good for someone switching from cigarettes?
The 0.8Ω coil with nicotine salt at 20mg to 50mg concentration is the configuration closest to cigarette-style use on this device. The draw is restricted (MTL), the throat sensation from salt nicotine is smooth compared to freebase at equivalent strength, and the output is controlled enough that you are not producing overwhelming vapour clouds. Whether this configuration suits a specific person depends on their individual smoking habits and nicotine tolerance. We describe the hardware; we do not make health or cessation claims.
What happens if the device does not suit me after purchase?
KandyVape operates a strict no-return, no-refund policy on all products. There are no exceptions for preference-based returns. This is why we publish detailed specifications and compatibility information before purchase rather than after. If a device is damaged or non-functional on arrival due to a manufacturing defect, contact us at the Mohammadpur shop as soon as possible for assessment. The policy details are available on our. We recommend reading that page before any purchase.
Does KandyVape dispatch orders on weekends, and how long does delivery take?
Yes. Orders dispatch daily at 3:00 PM including weekends. Delivery timeframes depend on your location. Confirm current delivery charges and timeframes for your area through our contact channels before ordering. Orders of 3,500 BDT and above qualify for free shipping.
Before You Order
The XLIM SQ Pro is a well-built, capable pod system. Its coil family is wide and flexible, and the battery is meaningfully larger than earlier XLIM devices. The spec is honest, the device is verifiable, and the cartridge system has enough variety to work for both a first-time user running salt nicotine at 0.8Ω and an experienced vaper running freebase at 0.4Ω.
Before ordering, check that the coil resistance you intend to use matches your nicotine type and strength using the table in this article. If you want to inspect the device and run the authenticity verification in person before committing, visit us at Shop 22, Level 3, Sahabuddin Plaza, Adabar, Mohammadpur 1207, Dhaka. If you are ordering online, place your order before 3:00 PM to dispatch the same day.
