OXVA XLIM Top Fill UNITECH 3.0 Replacement Pods – 3 Pack
The OXVA XLIM Top Fill UNITECH 3.0 Replacement Pods are the latest generation of refillable cartridges for the OXVA XLIM pod system. Introduced alongside the OXVA XLIM 4 Vape Kit, these replacement pods feature OXVA's upgraded UNITECH 3.0 mesh coil technology, a convenient top-fill design, improved e-liquid delivery and revised anti-leak construction.
Supplied in packs of three, the cartridges are available in 0.4Ω, 0.6Ω, 0.8Ω and 1.2Ω resistances, with 3ml international and 2ml TPD versions manufactured by OXVA. They support mouth-to-lung (MTL) and restricted direct-to-lung (RDL) vaping, depending on the chosen resistance and device settings.
The XLIM Top Fill UNITECH 3.0 pods use the established XLIM cartridge platform, making them compatible with the XLIM 4, XLIM Pro 3, XLIM Pro 4 and other supported XLIM devices. Each cartridge contains an integrated mesh coil, so no separate replacement coil is required.

What Is OXVA UNITECH 3.0 Technology?
UNITECH 3.0 is OXVA's updated cartridge technology, developed to improve e-liquid delivery, coil saturation, airflow and leak resistance within the XLIM pod platform.
Compared with earlier XLIM cartridge construction, UNITECH 3.0 introduces refinements to the mesh-to-cotton contact, internal airflow pathway and liquid-management structure.
According to OXVA, the updated design includes:
- Improved mesh-to-cotton contact to support consistent e-liquid vaporisation.
- Optimised curved airflow channels designed to reduce turbulence and draw resistance.
- Fast-Wick Cotton that OXVA states can saturate the heating area in approximately 30 seconds.
- Enhanced liquid-management seals designed to reduce e-liquid seepage.
OXVA also reports that its UNITECH 3.0 cartridge retained approximately 80% of its flavour performance after ten refills under its laboratory test conditions. This is manufacturer-reported data rather than independently verified performance, and individual results will vary according to e-liquid, wattage and use.
30-Second Quick Priming
One of the principal changes in UNITECH 3.0 is its updated wicking structure. OXVA describes a design that reduces air-bubble blockage and improves the flow of e-liquid towards the coil.
The manufacturer states that its Fast-Wick Cotton can saturate the heating area in around 30 seconds under specified conditions. This is intended to reduce the risk of dry hits associated with insufficient priming.
Actual saturation time may vary, particularly with thicker e-liquids. Always ensure a newly filled cartridge is fully primed before firing the device.
Enhanced Anti-Leak Design
The XLIM Top Fill UNITECH 3.0 pods incorporate a maze-shaped internal structure at the cartridge base, combined with OXVA's 360-degree sealing system.
These features are intended to limit e-liquid escaping through the cartridge base and airflow pathways. OXVA describes the latest generation as having improved anti-leak performance compared with its earlier designs.
No refillable cartridge is completely leak-proof under every condition. Overfilling, damaged seals, temperature changes and prolonged storage can still cause condensation or seepage.
OXVA XLIM UNITECH 3.0 Pod Resistance Guide
Four resistance options are available, covering different power ranges and vaping styles. The correct resistance depends on your XLIM device, preferred airflow restriction and e-liquid formulation.
| Resistance | Recommended Wattage | Typical Vaping Style |
|---|---|---|
| 0.4Ω | 26–30W | Restricted Direct-to-Lung (RDL) |
| 0.6Ω | 20–25W | RDL / Loose MTL |
| 0.8Ω | 12–16W | Mouth-to-Lung (MTL) |
| 1.2Ω | 10–12W | Tighter Mouth-to-Lung (MTL) |
Which UNITECH 3.0 Resistance Should You Choose?
0.4Ω: The lowest-resistance option, operating at 26–30W. Intended for a more open RDL draw on compatible higher-output XLIM devices.
0.6Ω: Operates at 20–25W and supports RDL or a looser MTL inhale, depending on airflow adjustment.
0.8Ω: Operates at 12–16W and supports MTL vaping. This is the resistance supplied with the OXVA XLIM 4 Vape Kit.
1.2Ω: The highest-resistance option, operating at 10–12W for a tighter, lower-powered MTL draw.
Always confirm that your device supports the chosen resistance. Some older or lower-powered XLIM devices may not support the complete wattage range of the 0.4Ω cartridge.
Which OXVA Devices Are Compatible With XLIM UNITECH 3.0 Pods?
The OXVA XLIM Top Fill UNITECH 3.0 cartridges use the established XLIM pod connection, allowing them to operate with compatible devices from the XLIM family.
Supported devices include:
- OXVA XLIM 4
- OXVA XLIM Pro 4
- OXVA XLIM Pro 3
- OXVA XLIM 3 Ultra
- OXVA XLIM GO 2
- OXVA XLIM GO Lite
- OXVA XLIM SQ Pro 2
- OXVA XLIM Pro 2
- OXVA XLIM GO
- OXVA XLIM SQ Pro
OXVA describes UNITECH 3.0 as compatible across its established XLIM cartridge platform. This list covers the main compatible devices rather than every historical model. Always check the supported resistance and cartridge specifications for your particular device.
Not compatible: These cartridges are not designed for OXVA NeXLIM, VPRIME or XLIM C devices, which use different pod systems.
Are These the Same Pods Included With the OXVA XLIM 4?
Yes. The OXVA XLIM 4 was introduced with the standard XLIM Top Fill UNITECH 3.0 cartridge system.
The manufacturer's UK/TPD XLIM 4 kit contains a 2ml 0.8Ω UNITECH 3.0 cartridge. Replacement packs use the same cartridge technology, with additional resistance options.
XLIM UNITECH 3.0 vs XLIM V3 vs XLIM ABT Pods
OXVA manufactures several cartridges for the XLIM platform. Although they share compatible connections, they do not all contain the same technology.
| Cartridge | Technology | ABT Anti-Burn? |
|---|---|---|
| XLIM V3 Top Fill | Earlier XLIM top-fill cartridge generation | No |
| XLIM Top Fill UNITECH 3.0 | Updated wicking, airflow and anti-leak construction | No |
| XLIM ABT UNITECH 3.0 | UNITECH 3.0 with Smart Liquid-Level Detection interface | Yes, with an ABT-enabled device |
The standard XLIM Top Fill UNITECH 3.0 pods do not include ABT Anti-Burn detection. They support normal vaping in compatible devices, including the XLIM Pro 4, but do not activate the device's liquid-level Anti-Burn function.
For comparison, see the earlier OXVA XLIM V3 Top Fill Pods or read about the separate XLIM ABT UNITECH 3.0 cartridge system.
What Is OXVA ABT Anti-Burn Technology?
OXVA's ABT system uses Smart Liquid-Level Detection to help prevent dry hits when a dedicated ABT cartridge is used with an ABT-enabled device. Learn how the systems differ in our OXVA ABT technology and compatibility guide.
What E-Liquid Works With XLIM UNITECH 3.0 Pods?
The XLIM Top Fill UNITECH 3.0 cartridges support suitable refillable pod-system e-liquids, including nicotine salt and freebase formulations.
For the higher-resistance 0.8Ω and 1.2Ω cartridges, balanced 50/50 PG/VG e-liquids are commonly used for lower-powered MTL vaping.
The 0.4Ω and 0.6Ω cartridges operate at higher wattages and may also be used with appropriate freebase or nicotine salt e-liquids, following the manufacturer's guidance.
Ubervape's nicotine salt e-liquid collection contains a range of pod-compatible options. Always check the selected liquid's PG/VG ratio, nicotine strength and recommended operating power.
How to Refill OXVA XLIM UNITECH 3.0 Pods
- Open the filling port: Lift the silicone seal covering the top-fill opening.
- Add e-liquid: Fill the cartridge carefully, avoiding the central airflow channel and overfilling.
- Secure the seal: Close the silicone plug firmly and wipe away excess liquid.
- Prime the coil: Allow a newly filled cartridge to saturate fully before use. OXVA advertises 30-second priming under its test conditions, but longer may be necessary.
- Use the correct power: Insert the cartridge into your compatible device and follow its recommended wattage range.
When Should You Replace an XLIM UNITECH 3.0 Pod?
Replace the complete cartridge when its integrated coil reaches the end of its usable life. Signs of coil deterioration may include a persistent burnt or unusual taste, reduced flavour, declining vapour production or ongoing leakage despite correct filling and maintenance.
Cartridge lifespan depends on e-liquid formulation, wattage, usage frequency and maintenance. There is no guaranteed number of days or refills for every user.

OXVA XLIM UNITECH 3.0 Pods – Frequently Asked Questions
Are XLIM UNITECH 3.0 pods compatible with the OXVA XLIM 4?
Yes. The XLIM 4 uses the XLIM Top Fill UNITECH 3.0 cartridge system and is supplied with a 2ml 0.8Ω version in its UK/TPD kit.
Can I use UNITECH 3.0 pods in my older OXVA XLIM device?
Yes, provided your device uses the compatible XLIM cartridge platform. Models such as the XLIM Pro 3, XLIM Pro 2, XLIM GO 2 and XLIM SQ Pro 2 are supported. Check your model's resistance and power specifications before use.
Do standard XLIM UNITECH 3.0 pods have Anti-Burn Technology?
No. Standard XLIM Top Fill UNITECH 3.0 cartridges do not have the ABT Smart Liquid-Level Detection interface. For liquid-level-based protection, a dedicated XLIM ABT cartridge and a compatible ABT-enabled device are required.
Do XLIM UNITECH 3.0 pods work with the XLIM Pro 4?
Yes. The XLIM Pro 4 accepts standard compatible XLIM Top Fill cartridges, including UNITECH 3.0. However, the ABT protection function is not active when a standard non-ABT pod is installed.
What is the difference between XLIM V3 and UNITECH 3.0 pods?
XLIM V3 cartridges belong to the previous top-fill generation. UNITECH 3.0 introduces an updated wicking structure, improved mesh-to-cotton contact, optimised airflow channels and revised anti-leak sealing. Both use the established XLIM cartridge platform.
Are XLIM UNITECH 3.0 pods the same as NeXLIM UNITECH 3.0 pods?
No. OXVA uses the UNITECH 3.0 name across different product families, but XLIM and NeXLIM cartridges have different physical designs and are not interchangeable.
How many OXVA XLIM UNITECH 3.0 pods are in a pack?
Each replacement pack contains three refillable cartridges in the selected resistance. No e-liquid or vape device is included.
Are OXVA XLIM UNITECH 3.0 pods available in 3ml?
Yes. OXVA manufactures a 3ml international version alongside a separate 2ml TPD version. UK regulations restrict refillable e-cigarette tank capacity to 2ml, so the 3ml version is not compliant for UK retail supply.
How long do XLIM UNITECH 3.0 pods last?
Lifespan varies with e-liquid, wattage and use. OXVA reports 80% flavour retention after ten refills under its laboratory conditions, but this does not guarantee a particular service life. Replace the cartridge when coil performance deteriorates.
