OXVA Xlim 4 Vape Kit

The OXVA Xlim 4 is a refillable pod kit with a 1600mAh built-in battery and up to 30W of power, built around OXVA's top-fill XLIM cartridges (UNITECH 3.0). It's slim enough to carry in a pocket, charges over USB-C, and takes the existing XLIM top-fill pod range, so it works with the pod resistances people already use for nicotine salts and standard e-liquid.

If you're upgrading from an earlier Xlim kit, you keep the pods you already know. If this is your first refillable pod system, the routine is easy: open the top port, add e-liquid, fit the pod and vape. This page covers what's included, which pods fit, what e-liquid to use, how to fill and care for the kit, and answers to the questions we hear most.

About the OXVA Xlim 4 vape kit

The Xlim line is OXVA's range of compact refillable pod kits, and the Xlim 4 is the newest model. It pairs a 1600mAh battery with up to 30W of output and the new UNITECH 3.0 top-fill cartridge, while staying compatible with the XLIM top-fill pods that earlier kits use.

That compatibility is a big part of the appeal. Pods are the part you buy again and again, and having one pod range across several kits means more choice of resistance, easy replacements and no need to relearn how your pod works. If you want a refillable alternative to single-use disposables, a kit like this lets you replace only the pod and refill it with the e-liquid you prefer.

OXVA Xlim 4 key features

• 1600mAh built-in battery. Built-in battery capacity to keep the kit going between charges.
• Up to 30W output. Enough range to suit higher-resistance pods at lower power as well as lower-resistance pods at higher power.
• Top-fill XLIM cartridges (UNITECH 3.0). Fill from the top without pulling the pod out of the device. Cartridges are available in 2ml and 3ml.
• Existing XLIM top-fill pod compatibility. Pods you already own should fit, and replacements are easy to find.
• USB-C (Type-C) charging. The same cable you probably already use for your phone or other devices.
• Compact build. About 121mm tall and 78.1g, so it sits comfortably in a pocket or bag.

Compatible pods for the OXVA Xlim 4

The Xlim 4 uses OXVA's XLIM top-fill cartridges and works with the existing XLIM top-fill pod range. The kit comes with a 0.8Ω cartridge, a resistance commonly used for mouth-to-lung and restricted direct-to-lung vaping. If you want a looser draw or a tighter one, you can swap in a different resistance. Browse our OXVA refillable pods for compatible replacements.

Always use the wattage range printed on the pod or recommended by OXVA for that pod. If you're using pods from a much older Xlim kit, check the pod's product page to confirm compatibility, as a few older models used different parts.

Best e-liquid for the OXVA Xlim 4

The right e-liquid depends on the pod you've fitted:

• Nicotine salts pair well with higher-resistance pods at lower power. They deliver nicotine smoothly and are the usual choice for compact pod kits. Browse nic salt e-liquids.
• Standard 50/50 and shortfill e-liquids suit lower-resistance pods at higher power for a bigger cloud and a looser draw. Browse our full e-liquid range.

Choose a nicotine strength that suits you. In the UK, nicotine e-liquid is limited to a maximum of 20mg/ml, and nicotine-free options are also available.

How to fill and use the OXVA Xlim 4

1. Charge first. Plug in the USB-C cable and charge the device fully before first use.
2. Fill the pod. Open the top fill port on the pod and add e-liquid. Leave a small air gap at the top and don't overfill.
3. Seal and fit. Close the port firmly and fit the pod into the device.
4. Let the coil soak. Wait a few minutes before your first draw so the coil can absorb the e-liquid. This helps prevent dry hits.
5. Power on and vape. Follow the manual for powering on and choosing your power level.
6. Replace when needed. Swap in a fresh pod when flavour fades or vapour weakens.

Battery, charging and safety

• Charge using the supplied cable or a reputable USB charger, and don't leave the device charging unattended.
• Don't deliberately run the battery completely flat. Recharge when it's low.
• Don't charge or use a device that's damaged, swollen or unusually hot.
• Keep the pod upright when not in use and wipe the pod contacts with a dry cloth if they get dirty.
• Keep the device, pods and e-liquid out of reach of children.

Nicotine is addictive. This product is for adult use only (18+).

Is the OXVA Xlim 4 right for you?

The Xlim 4 is a good fit if you want:

• A compact refillable kit with a 1600mAh battery and up to 30W of power
• Access to a wide range of top-fill pods in different resistances
• The option to move between nicotine salts and standard e-liquid by changing pod
• An upgrade that keeps the XLIM pods you already own

If you'd rather not refill at all, our prefilled pod vape kits are simpler. If you want another OXVA option, see the OXVA Xlim Pro Pod Kit or browse all OXVA vape kits and our wider refillable pod kits.

Troubleshooting your OXVA Xlim 4

• Weak vapour: Check the battery level and the pod's e-liquid level. Make sure the wattage matches the pod's recommended range.
• Burnt or dry taste: The coil may not have soaked long enough, or the pod is nearly empty. Refill, wait a few minutes, and take gentle draws. Replace the pod if the taste doesn't improve.
• Leaking: Usually caused by overfilling or a fill port that isn't fully closed. Leave an air gap when filling, close the port firmly and store the device upright.
• Flavour fading: The pod's coil is wearing out. Fit a new pod.
• Not charging: Try a different USB-C cable and charger, and check the port is free of debris. If it still won't charge, contact us.

OXVA Xlim 4 FAQs

What is the OXVA Xlim 4?

The OXVA Xlim 4 is a refillable pod kit with a 1600mAh built-in battery and up to 30W output. It uses top-fill XLIM cartridges (UNITECH 3.0) and charges over USB-C.

What's included in the OXVA Xlim 4 kit?

Which pods are compatible with the OXVA Xlim 4?

The Xlim 4 works with the existing XLIM top-fill pod range, including the UNITECH 3.0 top-fill cartridges. See our OXVA refillable pods.

Can I use my old Xlim pods in the Xlim 4?

Generally yes, as the Xlim 4 takes the existing XLIM top-fill pod range. If your pods come from a much older or special-edition kit, check the pod's product page to confirm.

What size are the pods?

XLIM top-fill cartridges are available in 2ml and 3ml sizes. Check the pod label or product page for the capacity of the one you're buying.

Can I use nicotine salts in the Xlim 4?

Yes. Nicotine salts pair best with higher-resistance pods (around 0.8Ω and above) at lower power. Standard 50/50 and shortfill e-liquids suit lower-resistance pods at higher power.

How do I fill the pod?

Open the top fill port, add e-liquid without overfilling, close the port, fit the pod and give the coil a few minutes to soak before vaping.

How do I charge the OXVA Xlim 4?

Plug the supplied USB-C cable into the port on the device. Don't leave it charging unattended, and don't run the battery completely flat.

How often should I change the pod?

Change the pod when flavour fades or vapour weakens. How long a pod lasts depends on your e-liquid, your power setting and how much you vape.

Why is my pod leaking?

Leaking is usually caused by overfilling, a loose fill port or a pod that isn't seated properly. Leave a small air gap when filling, close the port firmly and store the device upright.

Is the Xlim 4 suitable for beginners?

Yes. The top-fill design keeps refilling simple, and a wide pod range means you can adjust the draw as you learn what suits you.
