OXVA Xlim Pro 4 vs Xlim Pro 3: What's the Main Difference?

The biggest difference between these two pod kits is their approach to battery performance and pod technology. The Xlim Pro 3 focuses on consistent power delivery through its Intelligent Photon Chip and Pulse System. It also has a 1.05-inch HD screen that displays important information about the device.

The Xlim Pro 4 builds on the familiar XLIM design with an 1800mAh battery, 5V/3A charging and One-Tap Eco Mode. It also introduces UNITECH 3.0 cartridge technology and Anti-Burn Technology, which detects low e-liquid levels when used with a compatible ABT pod.

Both devices offer up to 30W output, adjustable airflow and two activation methods. This means the Pro 4 is not a move to a higher maximum wattage. Instead, its main changes relate to battery capacity, charging, cartridge technology and additional features.

1. Battery Capacity and Charging Speed

Battery performance is one of the clearest differences in the OXVA Xlim Pro 4 vs Xlim Pro 3 comparison.

The Xlim Pro 3 comes with a built-in 1500mAh battery. It supports USB-C charging at 5V/2A, with OXVA stating that it can reach around 80% charge in approximately 30 minutes under suitable conditions. Its battery capacity is designed to support regular daily use, although actual battery life depends on wattage, pod resistance and how frequently the device is used.

The Xlim Pro 4 increases battery capacity to 1800mAh and supports 5V/3A USB-C charging. This gives it a larger battery and a higher supported charging input than the Pro 3. The device is advertised as capable of a full charge in approximately 40 minutes under suitable charging conditions.

The Pro 4 also includes One-Tap Eco Mode, which helps conserve remaining battery power when needed. This can be useful when you want to manage the charge more carefully.

Which has the advantage? The Xlim Pro 4 has the larger battery and higher supported charging input. The Pro 3 remains a capable option for users who are happy with its 1500mAh battery and 2A charging.

2. Screen and Display Features

The OXVA Xlim Pro 3 features a 1.05-inch HD colour display. It shows useful details such as battery level, wattage, pod resistance and puff information. Its larger display is a practical feature for users who want settings and device information to be easy to read.

The Xlim Pro 4 uses a slightly smaller 0.98-inch HD colour screen. It adds customisable themes, vaping animations and lighting effects, giving users more options to change the appearance of the interface. The display also provides information about device settings and status.

Although the Pro 4 has the newer display system, the Pro 3 actually has the larger screen by the stated measurements. Both devices provide colour displays and access to important settings, so the difference comes down to screen size and visual customisation.

Which has the advantage? The Pro 3 has the larger screen, while the Pro 4 offers updated visual effects and customisation. The better option depends on whether you value display size or additional interface features.

3. Flavour Technology: Pulse System vs UNITECH 3.0

The Xlim Pro 3 uses OXVA's Intelligent Photon Chip and Pulse System. This technology is designed to maintain stable power delivery and help keep flavour consistent as the battery level drops. It also supports the device's adjustable output and pod-resistance management.

The Xlim Pro 4 introduces UNITECH 3.0 cartridge technology. OXVA describes it as an updated cartridge system designed to improve e-liquid delivery, airflow and flavour consistency. The Pro 4 also includes Anti-Burn Technology when paired with a compatible ABT cartridge.

These systems have different roles. Pulse System focuses on consistent power delivery, while UNITECH 3.0 is a cartridge technology. The Pro 4's ABT feature adds a further layer of protection by detecting when compatible pods have low or no e-liquid.

Both devices are designed to deliver a consistent experience, but flavour also depends on the selected pod, e-liquid, wattage and airflow settings.

Which has the advantage? The Pro 3 remains notable for its Pulse System, while the Pro 4 adds updated cartridge technology and compatible-pod Anti-Burn protection.

4. Anti-Burn Technology on the Xlim Pro 4

Anti-Burn Technology is one of the main features that separates the Xlim Pro 4 from the Pro 3.

When used with a compatible XLIM ABT cartridge, the Pro 4 can detect when the e-liquid level is too low or empty. The device can then provide a refill alert and help reduce the chance of a dry hit caused by vaping when there is not enough e-liquid in the pod.

This protection depends on using a compatible ABT cartridge. Standard XLIM top-fill pods can work with the device, but they do not provide the same Anti-Burn functionality.

The Pro 3 supports compatible XLIM pods and offers a refillable design, but it does not provide the Pro 4's dedicated ABT feature.

Which has the advantage? The Xlim Pro 4 is the better option if compatible-pod Anti-Burn Technology is an important feature for you.

5. Pod Compatibility and Refilling

Both the Xlim Pro 3 and Pro 4 belong to the XLIM family, giving users access to a selection of compatible refillable cartridges. Depending on the specific pod model, resistance options include 0.4Ω, 0.6Ω, 0.8Ω and 1.2Ω.

The Xlim Pro 3 supports Xlim V3 pods, Xlim V2 pods and Xlim EZ cartridges, alongside other compatible pods. Its supplied kit includes 0.6Ω and 0.8Ω top-fill pods. These resistance options allow users to select a draw that suits their preferred MTL or RDL style.

The Xlim Pro 4 supports compatible Unitech 3.0 Pods, V3 Top-Fill Pods, Xlim EZ Pods, Xlim SS Top-Fill Pods, XLIM cartridges, including the newer UNITECH 3.0 range. Its supplied kit includes 0.6Ω and 0.8Ω ABT cartridges. When an ABT cartridge is fitted, the device can use its Anti-Burn functionality. Other compatible XLIM cartridges operate without that particular protection.

Pod capacity depends on the version supplied. UK TPD-regulated versions generally use 2ml cartridges, while larger-capacity versions may be available in other markets. Always check the specific product listing before ordering replacement pods.

If you need new cartridges, explore OXVA XLIM replacement pods at Vape Universe. You can also browse refillable vape pods to compare replacement options for compatible devices.

Which has the advantage? Both offer a broad selection of compatible pods. The Pro 4 has the additional benefit of ABT cartridges, while the Pro 3 remains suitable for users who already use compatible XLIM pods.

6. Output Power, Airflow and Vaping Styles

There is no difference in maximum output power between the two devices. Both the Xlim Pro 3 and Xlim Pro 4 offer adjustable output of up to 30W, allowing settings to be matched to the selected compatible pod.

Both also feature adjustable side airflow. This allows users to change the draw from a tighter mouth-to-lung (MTL) style to a more open restricted-direct-to-lung (RDL) style. The appropriate resistance and wattage depend on the pod being used.

The Pro 3 includes smart wattage features designed to help users select suitable settings. The Pro 4 also offers adjustable output, while its additional Eco Mode provides another option for managing battery use.

Neither device requires users to choose between button activation and inhalation activation, as both support auto-draw and button firing.

Which has the advantage? These features are broadly similar. If maximum wattage, airflow adjustment and activation options are your main priorities, the Pro 3 and Pro 4 offer much the same core functionality.

7. E-Liquid Compatibility: What Should You Use?

Both devices are refillable pod kits, so you can select a compatible e-liquid rather than relying on prefilled cartridges. The correct option depends on the pod resistance, recommended wattage and your preferred vaping style.

Nicotine salt e-liquids are commonly used in lower-powered pod kits with suitable higher-resistance pods. You can browse the range of nic salt e-liquids at Vape Universe to explore available flavours and strengths.

Some compatible pods can also be used with suitable freebase e-liquids. Check the manufacturer's recommended resistance, wattage and PG/VG ratio before filling your pod. Not every liquid is suitable for every cartridge.

You can also explore the wider e-liquid collection for different liquid types and flavours. Always follow the product instructions and choose a liquid suitable for your device.

Which has the advantage? Both devices offer flexibility through compatible refillable pods. Your choice of e-liquid should be based on pod compatibility and the manufacturer's guidance rather than the device alone.

8. Coils and Replacement Parts

Unlike traditional vape tanks that use separate replaceable coils, the XLIM pod options described for these devices generally have an integrated coil within the cartridge. When the pod reaches the end of its usable life, you usually replace the entire compatible pod rather than removing a separate coil.

This makes it important to choose the correct replacement cartridge. Check the resistance, pod type and device compatibility before ordering.

Vape Universe also stocks a wider selection of replacement vape coils for compatible tanks and devices from other brands. These are useful if you own another vape kit that uses replaceable coils, but they should not be purchased as substitutes for XLIM replacement pods.

Which has the advantage? Both the Pro 3 and Pro 4 use compatible XLIM pod options. Choose the correct replacement pod for your model and use separate replacement coils only with devices designed to accept them.

9. Design, Colours and Everyday Use

Both devices use a compact, portable design with a colour screen and side airflow adjustment. The Xlim Pro 3 measures approximately 119.9 × 25.7 × 15mm and weighs around 77.4g, according to the supplied specifications.

The Pro 3 comes in a range of finishes, including Black Leather, Brown Leather, Pro Carbon, Black Carbon, Sky Blue, Race Red, Pink Silk, Purple Silk and Titanium Silk. Other finishes may be available depending on the market and retailer.

The Xlim Pro 4 is available in ten finishes, including Flowing Dark Blue, Flowing Moonlight, Flowing Midnight, Flowing Ice Blue, Flowing Rose Pink, Stardust Purple, Stardust Blue, Black Carbon, Cocoa Black Leather and Glacier Grey Leather.

The Pro 4's LED Matrix lighting and customisable screen effects give it a different appearance, while the Pro 3's larger display remains one of its distinguishing features.

Price is an important factor when comparing two devices with similar core features.

Final Verdict: Is the Xlim Pro 4 Better Than the Xlim Pro 3?

The OXVA Xlim Pro 4 introduces several useful changes over the Xlim Pro 3, particularly its larger battery, faster charging specification, Eco Mode and compatible-pod Anti-Burn Technology. Its UNITECH 3.0 cartridge system and updated display effects also distinguish it from the previous model.

However, the Xlim Pro 3 remains a capable refillable pod kit. It offers the same maximum 30W output, adjustable airflow, auto-draw and button activation, along with a larger 1.05-inch screen and Pulse System technology.

At Vape Universe, the £1.49 price difference makes the Pro 4 worth comparing closely if you want its additional features. The Pro 3 may still suit users who prefer its screen and are satisfied with its battery and charging specifications.
