OXVA Xlim 4 Pro Vape Kit

The OXVA Xlim 4 Pro Vape Kit, also written Xlim Pro 4, is a refillable pod kit with a 1800mAh battery, adjustable 5W to 30W output, a 0.98-inch HD colour screen and ABT Anti-Burn Technology, which helps reduce the risk of dry hits. Airflow runs from a tight mouth-to-lung (MTL) draw to a looser restricted direct-to-lung (RDL) one, and it fires on draw or by button. It suits anyone who wants an Xlim with more control and a safeguard against burnt pods.

This page explains how ABT works, which pods unlock it, how to choose a resistance and what is in the box. You can also browse the full OXVA range of kits and pods.

What Is the OXVA Xlim 4 Pro?

The Xlim 4 Pro sits above the standard Xlim 4 in OXVA's current range. OXVA's own name for it is the Xlim Pro 4, and some stores list it as the Xlim 4 Pro, so you may see both. It keeps the slim zinc-alloy body with IML and PU leather finishes, and adds what the standard Xlim 4 lacks: adjustable wattage, a full colour screen, faster charging and anti-burn protection.

It is a refillable pod kit, so you fill the pods yourself, and the pods have built-in mesh coils, so you replace the whole pod when it is finished. Two ABT pods are in the box, and the kit also takes standard Xlim UNITECH 3.0 pods, as explained below.

ABT Anti-Burn Technology

ABT, or Anti-Burn Technology, uses what OXVA calls Smart Liquid-Level Detection. As the e-liquid runs low, the screen shows a "Please Fill The Pod" alert. If you carry on vaping, the kit cuts power to the coil so the wick does not burn. Once you refill, it detects the new level and returns to normal.

The benefit is easy to picture: fewer accidental dry, burnt hits when you do not notice a pod running low. To be clear about the limits, ABT only works with ABT pods, only when the feature is switched on, and it helps reduce the risk of dry hits rather than preventing every one. Coils still wear out with normal use, so you will still replace pods when flavour fades. OXVA has not published how the detection works, so treat it as a safeguard, not a guarantee.

With an ABT pod fitted, ABT is switched on or off by pressing the button eight times, according to OXVA's instructions.

Which Pods Does the Xlim 4 Pro Use?

This is the question most buyers ask, because two Xlim pod types fit the kit. Both have a built-in UNITECH 3.0 mesh coil and hold 2ml, the UK TPD limit. The difference is anti-burn.

For the full Xlim 4 Pro experience, refill with ABT pods. If you already have standard pods, they fit and work normally, just without the liquid-level protection, and you can find them on our standard UNITECH 3.0 pods page, which explains the difference in more detail. Resistance and wattage are printed on the base of every pod.

Pod Resistances and Vaping Style

The kit comes with a 0.6ohm ABT pod already fitted and a 0.8ohm ABT pod as a spare. The 0.4ohm and 1.2ohm ABT pods are sold separately. Choose a resistance by the draw you want.

Mouth-to-lung, or MTL, is a tighter draw taken into the mouth first and then inhaled. Restricted direct-to-lung, or RDL (also written RDTL), is a looser draw with more air and warmth. The adjustable airflow slider on the side moves between the two: tighter airflow gives more concentrated flavour and a stronger throat hit, while looser airflow gives more vapour.

For a cigarette-style MTL draw, fit the 0.8ohm or 1.2ohm pod and close the airflow down. For a more open RDL draw, use the 0.4ohm or 0.6ohm pod and open the airflow up. Start at the lower end of the wattage range with a new pod, then raise it if you want a warmer draw.

Eco Mode, Pulse and Wattage Control

Wattage is adjustable from 5W to 30W. Press the button three times to change it, and match it to your pod using the table above.

Eco Mode is a quick-tap option that reduces screen power to extend battery life, which helps when the charge is running low. Pulse is listed by retailers as providing a steady output even when the battery is low, so the vape stays consistent as the charge drops. Check the manual in the box for the full details of each.

Display and Controls

The 0.98-inch HD colour screen shows battery level, wattage, puff count and charging status, with a live charging countdown. There are four display themes, three vaping animations and adjustable lighting effects, all set from the menu, so you can personalise how it looks.

To fire it, draw on the mouthpiece for automatic activation, or press and hold the button while you inhale. The button also handles the controls:

The click counts are as listed by UK retailers and in OXVA's instructions, so check the manual if your kit differs.

Battery and Charging

The 1800mAh battery is built in and charges over USB-C, rated for 5V/3A. A full charge takes roughly 40 to 45 minutes. A USB-C cable is in the box but a charging adapter is not, so use a 5V/3A adapter to get the rated speed.

Runtime depends on your wattage, your pod and how often you vape. The screen shows a live battery readout, so you can see where you stand. Always charge on a safe surface and do not leave the kit charging unattended.

Which E-Liquid to Use

The Xlim 4 Pro works with nic salt and freebase e-liquid, and 50/50 is the usual match for these pods. Nic salts suit the tighter 0.8ohm and 1.2ohm pods, where a smoother throat hit makes higher strengths more comfortable. A 50/50 freebase suits the more open 0.4ohm and 0.6ohm pods, generally at lower strengths because you draw in more vapour per puff. Very thick, high-VG sub-ohm shortfills are better kept for sub-ohm kits. Browse our nic salt e-liquid range to find a flavour to match your pod.

Xlim 4 Pro vs Xlim 4

If you are weighing the Xlim 4 Pro against the standard Xlim 4, this table shows the main differences. The Xlim 4 figures are as listed by UK retailers.

In short, the Xlim 4 Pro adds a bigger battery, faster charging, adjustable wattage, a full colour screen and ABT. Both take Xlim pods, but only the Xlim 4 Pro unlocks anti-burn with ABT pods. Choose the Xlim 4 for a simpler setup, or the Xlim 4 Pro if you want more control and anti-burn protection.

Colours

The Xlim 4 Pro comes in ten colours: Black Carbon, Cocoa Black Leather, Flowing Dark Blue, Flowing Ice Blue, Flowing Midnight, Flowing Moonlight, Flowing Rose Pink, Glacier Grey Leather, Stardust Blue and Stardust Purple. Every colour has the same specification, so only the finish changes.

Frequently Asked Questions

What is ABT Anti-Burn Technology on the Xlim 4 Pro?

ABT uses OXVA's Smart Liquid-Level Detection. When the e-liquid runs low, the Xlim 4 Pro shows a "Please Fill The Pod" alert and, if you keep vaping, cuts power to the coil so the wick does not burn. After you refill, it resumes normally. It helps reduce the risk of dry, burnt hits, but only works with ABT pods and only when switched on.

Which pods does the OXVA Xlim 4 Pro use?

The kit uses XLIM ABT UNITECH 3.0 pods, which have a built-in mesh coil and hold 2ml. A 0.6ohm pod is pre-installed and a 0.8ohm spare is in the box. These ABT pods unlock the anti-burn function. Standard UNITECH 3.0 pods also fit, but without anti-burn, so use ABT pods for the full experience.

Does anti-burn work with any Xlim pod?

No. Anti-burn only works with ABT pods, and only when the feature is switched on. If you fit a standard Xlim pod, the kit still works as a normal pod device, you just do not get the liquid-level detection. ABT pods have four base contacts, an ABT mark underneath and a red silicone ring at the mouthpiece, so they are easy to spot.

What pod resistances are available, and which are included?

There are four: 0.4ohm (26-30W) and 0.6ohm (20-25W) for a looser RDL draw, and 0.8ohm (12-16W) and 1.2ohm (10-12W) for a tighter MTL draw. The kit includes the 0.6ohm, pre-installed, and a 0.8ohm spare. The 0.4ohm and 1.2ohm ABT pods are sold separately, and the resistance is printed on each pod's base.

Is the Xlim 4 Pro MTL or RDL?

It is both, depending on the pod and the airflow. With the 0.8ohm or 1.2ohm pod and the airflow slider closed down, it gives a tight, cigarette-style mouth-to-lung (MTL) draw. With the 0.4ohm or 0.6ohm pod and the airflow opened up, it becomes a restricted direct-to-lung (RDL) vape with more air and vapour. The slider lets you fine-tune the draw.

What do Eco Mode and Pulse do?

Eco Mode reduces screen power to extend battery life, which helps when the charge is running low. Pulse is listed by retailers as keeping a steady output even when the battery is low. You can also set the wattage yourself between 5W and 30W by pressing the button three times, so you choose how much power each pod gets. See the manual for details.

How long does the Xlim 4 Pro battery last, and how long does it take to charge?

It has an 1800mAh built-in battery, and runtime depends on your wattage, your pod and how often you vape. It charges over USB-C at up to 5V/3A, and a full charge takes roughly 40 to 45 minutes. The box includes a USB-C cable but not an adapter. The screen shows a live battery readout and a charging countdown.

What e-liquid should I use in the Xlim 4 Pro?

50/50 e-liquid is the usual match for these pods, in nic salt or freebase. Nic salts suit the tighter 0.8ohm and 1.2ohm MTL pods, while 50/50 freebase suits the more open 0.4ohm and 0.6ohm pods at lower strengths. Very thick, high-VG sub-ohm shortfills are better kept for sub-ohm kits rather than a pod kit like this.

How do I fill the Xlim 4 Pro pod?

Open the silicone fill port on top of the pod, add your e-liquid up to the line and press the port fully shut. Then let the pod prime for around 30 seconds so the mesh coil can absorb the liquid before your first draw, and start at the lower end of the wattage range. Do not overfill, which helps avoid leaks.

How is the Xlim 4 Pro different from the Xlim 4?

The Xlim 4 Pro has a bigger 1800mAh battery (the Xlim 4 has 1600mAh), adjustable 5W to 30W wattage instead of three set power levels, a 0.98-inch HD colour screen instead of a ring light, faster 5V/3A charging against 5V/2A, and ABT anti-burn, which the Xlim 4 does not have. The Xlim 4 figures are as listed by UK retailers.

What does the Xlim 4 Pro screen show?

The 0.98-inch HD colour screen shows battery level, wattage, puff count and charging status, with a live charging countdown. It also has four display themes, three vaping animations and adjustable lighting effects, set from the menu, so you can personalise how it looks. It is a clear step up from the simple ring light on the standard Xlim 4.

Is the Xlim 4 Pro draw or button activated, and what is in the box?

It is both. You can draw on the mouthpiece to fire it automatically, or press and hold the button while you inhale. In the box you get the Xlim 4 Pro device, a 0.6ohm pod (pre-installed) and a 0.8ohm spare, both XLIM ABT UNITECH 3.0, a USB-C cable, a user manual and a suggestion card. Add your own e-liquid.
