OXVA XLIM 4 Pod Kit Review What’s New and Is It Worth Buying?

The OXVA XLIM Pro 4 Pod Kit feels like OXVA has stopped trying to cram every possible feature into one small device and has instead focused on the things people actually use every dayin Oxva Pod Kits.

Battery life? Better.
Power control? Still there, but kept simple.
Pods? Upgraded.
Airflow? Adjustable.

That’s basically the direction of the XLIM 4.

It runs between 5W and 30W, carries a much larger 1600mAh battery, and introduces OXVA’s newer UNITECH 3.0 XLIM pod. Instead of giving you a screen full of settings, OXVA has gone with three power levels and a ring light that shows battery and power information. 

For someone who already likes the XLIM range, this one won’t feel unfamiliar. It just feels a bit more settled.

What Is the OXVA XLIM 4?

The OXVA XLIM 4 is a compact refillable pod kit built for both MTL and RDL vaping.

It uses refillable XLIM pods rather than prefilled cartridges, so you choose your own e-liquid, fill the pod and replace the cartridge when the built-in coil eventually wears out.

Power goes up to 30W, although you don’t have to sit there adjusting wattage one number at a time.

Instead, there are three selectable power levels.

Double-click the control to move between them, and the device handles the rest according to the pod fitted. 

That’s probably a better setup for this sort of vape anyway.

OXVA XLIM 4 Key Features

• 5-30W output

• Three power levels

• 1600mAh built-in battery

• 5V/2A USB-C charging

• Auto-draw activation

• Side airflow adjustment

• MTL and RDL vaping

• XLIM UNITECH 3.0 top-fill pod

• 2ml TPD pod for the UK

• 0.8Ω pod included in the TPD kit

• Compatible with 0.4Ω, 0.6Ω, 0.8Ω and 1.2Ω XLIM pods

• Nic salt and freebase e-liquid compatibility

• Ring light battery indicator

• Two selectable light effects

• Zinc alloy construction

• 10 colour options

• 78.1g weight

The XLIM 4 measures 121mm x 26.2mm x 15.2mm, so it’s still a fairly slim device despite the jump in battery size. 

The 1600mAh Battery Is Probably the Biggest Upgrade

A pod kit lives or dies by its battery.

You can have a nice screen and fancy animations, but none of that matters much if you’re looking for a charger halfway through the day.

OXVA has fitted the XLIM 4 with a 1600mAh battery, which is noticeably larger than several earlier XLIM devices.

It charges at 5V/2A through USB-C as well, so charging speed hasn’t been sacrificed just because the battery has grown. 

For everyday use, that extra capacity is probably more valuable than another menu or theme.

Not very glamorous, perhaps. Still useful.

Three Power Levels Instead of Full Wattage Adjustment

OXVA has done something slightly different with power control here.

The XLIM 4 can output between 5W and 30W, but rather than making you manually scroll through every wattage setting, it uses three power levels.

A double-click moves between them.

The idea is fairly obvious: keep some control over vapour and flavour without turning a simple pod kit into something that needs constant adjusting. 

For most XLIM users, that will probably be enough.

If you’re the sort of person who wants to choose exactly 17W instead of 18W, there are other OXVA devices that give you finer control.

The XLIM 4 isn’t really chasing that user.

UNITECH 3.0 Pods: What Actually Changed?

The UNITECH 3.0 cartridge is one of the headline changes.

OXVA says it has worked on several parts of the pod together rather than simply changing the coil.

That includes airflow, heating, liquid delivery, wicking and sealing. 

The result, according to OXVA, is better vapour production, steadier flavour and improved resistance to leaking.

There’s also a claimed 30-second priming time with the new pod.

Fill it, wait around half a minute, then use it.

That’s much shorter than the five or ten minutes people often leave a new pod sitting before the first puff, although giving cotton a little extra time never hurts if you’re not in a rush. OXVA specifically lists the quick-priming system as part of the UNITECH 3.0 design. 

Does the XLIM 4 Leak?

No refillable pod can sensibly be described as completely impossible to leak.

Still, OXVA has clearly paid attention to it.

The company describes the new UNITECH 3.0 pods as having upgraded anti-leak protection, with changes made to the internal sealing and liquid delivery system. 

That matters because a pod kit normally spends a lot of time in a pocket or bag.

A little condensation around the pod connection can happen with almost any vape. A tank full of liquid in your pocket is a different story.

OXVA is obviously trying to avoid the second one.

Adjustable Airflow Makes More Difference Than It Sounds

There’s a side airflow slider on the XLIM 4.

Move it one way and the draw tightens up. Move it the other and you get a more open inhale.

OXVA positions the device for both MTL and RDL vaping, and that airflow adjustment is what makes the switch possible. 

A tighter setup works well if you prefer something closer to the resistance of a cigarette.

Open it up and it becomes noticeably airier.

This is one of those controls that people tend to set once, fiddle with for a day or two, then leave exactly where they like it.

And that’s fine.

What Does the Ring Light Do?

There’s no traditional colour screen on the XLIM 4.

Instead, OXVA has built a visible ring light into the device.

It shows the selected power level, battery status and vaping effects. Battery information is split into three ranges:

• 65-100%

• 30-65%

• 0-30%

You can also switch between two light effects by pressing the control four times. 

Is that essential?

No, but it gives you the information you actually need without adding a larger screen just for the sake of having one.

Which Pods Work with the OXVA XLIM 4?

This is where the XLIM series remains easy to recommend.

The XLIM 4 works with the new XLIM Top Fill UNITECH 3.0 cartridges as well as existing XLIM Top Fill pods. OXVA lists compatibility with:

• 0.4Ω

• 0.6Ω

• 0.8Ω

• 1.2Ω

UK TPD versions use 2ml pods. 

That gives you a decent amount of room to change how the device feels without replacing the kit.

Which XLIM Pod Resistance Should You Choose?

The resistance you pick changes the vape more than people sometimes realise.

0.4Ω

This is the lowest resistance option.

It’s better suited to a warmer, more open RDL vape and works at the higher end of the XLIM 4’s power range.

Expect more vapour and faster e-liquid use.

0.6Ω

A nice middle ground.

The 0.6Ω pod can work for RDL or a looser MTL draw, depending on how you set the airflow.

If you don’t like an extremely tight inhale, this is an easy place to start.

0.8Ω

The UK TPD kit comes with the 0.8Ω UNITECH 3.0 pod. 

It suits MTL vaping well and works nicely with nicotine salts and standard 50/50 e-liquids.

For most everyday pod-kit users, this will probably be the obvious option.

1.2Ω

The 1.2Ω pod gives the tightest draw and uses less power.

It’s aimed more squarely at MTL vaping and people who prefer a smaller amount of vapour.

What E-Liquid Works Best in the XLIM 4?

OXVA lists the XLIM 4 pods for use with both nic salts and freebase e-liquids. 

For UK users, 50/50 VG/PG e-liquid is the easiest match with the 0.8Ω and 1.2Ω pods.

Nicotine salts work particularly well with the tighter MTL setup.

If you move down to a 0.4Ω or 0.6Ω pod and open the airflow, a lower-strength freebase liquid may make more sense.

The pod resistance and nicotine strength should work together.

Using a very strong nic salt at a much more open, higher-power setting can quickly become unpleasant.

How Easy Is the OXVA XLIM 4 to Use?

• Fill the pod, let the wick absorb the liquid, push the pod into the device and inhale.

• The XLIM 4 uses auto-draw, so you don’t have to press a fire button while vaping. 

• The single control is mainly there for checking information and changing power or light settings.

• One press shows battery and power information.

• Two presses change power.

• Four presses switch the light effect. 

• That’s about as much button learning as most people need.

How Does the XLIM 4 Feel as an Everyday Vape?

• The 1600mAh battery is large enough to be genuinely useful, yet the body remains narrow at just over 15mm thick.

• It weighs 78.1g, so this isn’t the lightest stick-style pod OXVA has made. That extra weight comes with the bigger battery and zinc alloy body. 

• A little weight can make a device feel more solid in the hand.

• Others may prefer something lighter such as an XLIM GO.

• That part comes down to taste more than performance.

OXVA XLIM 4 vs Older XLIM Kits

The XLIM family is getting fairly crowded now.

That can make choosing one confusing.

The XLIM 4’s place is easier to understand if you look at what it doesn’t try to do.

There’s no large touchscreen like the XLIM 3 Ultra.

There isn’t a big HD display like the XLIM Pro 3 either.

Instead, the XLIM 4 gives you:

• Larger 1600mAh battery

• Three simple power levels

• Ring light information

• Adjustable airflow

• Auto-draw

• New UNITECH 3.0 pods

• Up to 30W

OXVA’s own comparison places it below the more feature-heavy Pro models, while keeping the same broad MTL/RDL flexibility. 

Who Is the OXVA XLIM 4 Best For?

The XLIM 4 makes sense for someone who wants a refillable pod kit without turning vaping into a hobby.

You may like it if you want:

• A big battery in a slim device

• Adjustable airflow

• Simple power control

• Refillable 2ml pods

• Nic salt compatibility

• Both MTL and RDL options

• Auto-draw activation

• Access to different XLIM pod resistances

It also looks like a sensible upgrade for someone using an older XLIM model who wants longer battery life without moving to a larger touchscreen device.

Who Might Prefer Something Else?

If you want detailed wattage adjustment and a proper display, the XLIM Pro 3 gives you more control.

Someone after a touchscreen may prefer the XLIM 3 Ultra.

And if you just want the lightest, cheapest XLIM possible, a simpler XLIM GO model may suit you better.

That doesn’t make the XLIM 4 worse.

It just tells you what sort of product it is.

Why Buy the OXVA XLIM 4 from WizVape UK?

The OXVA XLIM 4 fits well into the sort of kit many UK vapers are already comfortable using: refillable pod, 2ml capacity, nic salt compatibility and straightforward controls.

At WizVape UK, it also makes sense to compare it with other OXVA kits before deciding.

You may find that the XLIM 4’s larger battery is exactly what you wanted. Or perhaps you’d rather have the bigger screen and finer controls of one of the Pro models.

The point is to buy the one that fits how you actually vape, not whichever device has the longest feature list.

A 50/50 liquid is a good match for the tighter MTL setup.

Does the OXVA XLIM 4 have adjustable wattage?

Not in the usual one-watt-at-a-time way.
The device uses three selectable power levels within its 5-30W output range.
Double-clicking the control switches between them. 

Is the OXVA XLIM 4 MTL or RDL?

It can do both.
The adjustable airflow and four pod resistances let you move from a tight MTL draw to a more open RDL inhale.
Your pod choice makes the biggest difference.

Is the OXVA XLIM 4 Worth It?

For most people looking at the XLIM range, the XLIM 4 is easy to understand.

You get a 1600mAh battery, up to 30W, adjustable airflow and a much simpler three-level power system instead of loads of settings.

The new UNITECH 3.0 pod is arguably the more interesting part. If the improved liquid delivery and leak resistance work as OXVA intends, that’s the sort of upgrade you’ll notice every day rather than something you play with once and forget about.
