Freemax Rexa S2 vs OXVA Xlim Go 2 vs Uwell Caliburn G5 Lite: Which Pod Kit to Buy in Pakistan
If you have Rs 3,500 to Rs 4,000 for a pod kit in Pakistan, three names keep coming up: the new Freemax Rexa S2, the OXVA Xlim Go 2 and the Uwell Caliburn G5 Lite. All three are refillable, all three fire when you draw, and all three have a battery around 1500mAh. So which one is actually better for you? This guide compares them on battery, power, pods, build and price, using each brand’s own specs, and ends with a straight answer for each type of vaper. Short version: the Caliburn G5 Lite at Rs 3,699 is the cheapest with the biggest battery, the Xlim Go 2 at Rs 3,999 is the simplest and charges fastest, and the Rexa S2 at Rs 3,799 is the only one with a screen, adjustable wattage and two pods in the box.

About the Rexa S2 battery: Freemax’s website lists the S2 at 1300mAh, but the boxes of the units we sell are printed with 1500mAh, so that is what we show. For the G5 Lite, shops abroad list slightly different heights, so we give a range rather than one number.
Battery life and charging
On paper the Caliburn G5 Lite wins with 1600mAh, and Uwell says it can last up to 6 days on one charge. OXVA says the Xlim Go 2 lasts up to 5 days with its 0.8 ohm pod. Freemax does not give a days figure for the S2. Treat these as light use numbers. One UK test of the Go 2 got a full day and a bit of heavy vaping, and estimated two to three days for an average user, which is a fairer guide for a pack a day smoker who has just switched.
The real difference is how much power each one draws. The Go 2 and G5 Lite choose the wattage from the pod, so a 0.8 ohm pod sips power and the battery lasts. The Rexa S2 lets you push it to 30W, and if you do that with a 0.4 ohm pod the battery goes much faster. Keep the S2 around 12 to 15W with the 0.8 ohm pod and it will behave like the other two.
For charging, the Xlim Go 2 is the clear winner. It charges at 2A and OXVA says it reaches about 80% in 30 minutes. The Rexa S2 charges at 1A, so it takes longer. Uwell does not list a charging rate for the G5 Lite on its page. All three use the same Type-C cable as most Android phones.
Power, screen and controls
This is where the three really split apart.
The Rexa S2 is the only one you can tune. A small display on the front shows your wattage, and three clicks let you set it anywhere from 5W to 30W. One click changes the light colour around the screen, two change the lighting effect, and four clicks switch off draw firing. Freemax calls that a child resistant lock. It is also handy if the device sits in a bag where it could fire by accident. Five clicks turn it off.
The Xlim Go 2 has no buttons at all. You fill it, slide the airflow, and inhale. A light on the front shows the battery level. The only thing you choose is the pod resistance. For someone leaving cigarettes or disposables, that simplicity is the whole point.
The Caliburn G5 Lite is the same idea as the Go 2. It fires on draw, the chip sets the power from the pod, and a 4-bar light shows the battery. Its strength is the airflow: Uwell gives it dual adjustable airflow that goes from a tight mouth to lung (MTL) pull to a looser restricted lung (RDL) one, and it reaches 35W with the 0.4 ohm pod, the highest of the three.
Pods: which ones fit and what they cost
A pod kit is only as cheap as its pods, so check this before you buy. None of these three share pods with each other.
- Rexa S2: takes every REXA pod. Two come in the box: a 0.6 ohm DUOMAX double mesh pod (18 to 23W) and a 0.8 ohm pod (12 to 15W). Spares: Freemax Rexa 0.4 ohm pods, Rs 899. The S2 pods fill from the side under a slide cover.
- Xlim Go 2: takes all XLIM top fill pods, 0.4, 0.6, 0.8 and 1.2 ohm. Spares: OXVA Xlim 3ml pods, Rs 799. The fill hole sits under a silicone plug on top. It is quick to fill, though the plug can be fiddly to push back in.
- Caliburn G5 Lite: takes Uwell GPP pods, the same pods as the Caliburn G3, G4 and G5. Older G2 and GK2 pods do not fit. Spares: Caliburn GPP 3ml pods, Rs 899.
The Rexa S2 gives you the most to start with, because two pods in the box means your first spare is already paid for. XLIM pods are the cheapest spare at Rs 799, and UK testers rate XLIM pods well for flavour and pod life. GPP pods are the easiest to find later, because so many Caliburn models use them.
For nicotine salt at 20mg to 30mg, use a 0.8 ohm pod (or the 0.6 ohm on the G5 Lite) with the airflow mostly closed. For a looser draw, use a 0.4 ohm pod with low strength liquid. Our nicotine salt guide explains strengths if you are new.
Build, size and feel
The Rexa S2 has a zinc alloy body with a raised X pattern, in a gloss or a leather texture front. It is the longest of the three at about 132mm and the heaviest feeling, which some people like and some find too big for a shirt pocket. The Xlim Go 2 is a light plastic (PCTG) shell at about 46g. It is easy to carry, but it does not feel as solid in the hand. The Caliburn G5 Lite has a translucent shell over a coloured core and is the shortest of the three, so it is the easiest to hide in a palm or a jeans pocket.
Which one should you buy?
- Lowest price and biggest battery: Caliburn G5 Lite (Rs 3,699). 1600mAh, up to 35W and pods you can find anywhere. If you are not sure, this is the safe pick.
- Simplest device, fastest charging: Xlim Go 2 (Rs 3,999). No buttons, a 3ml pod and 2A charging. Good for a first device or for someone who will forget to charge it.
- Want control and a screen: Rexa S2 (Rs 3,799). Set the wattage yourself, lock the firing, change the lights, and start with two pods. Good if you will try different liquids and pods.
- Like the Rexa but want to spend less: the Freemax Rexa S at Rs 3,199 has the same 1500mAh box rating and 30W range with a hidden screen and one pod. Our Rexa S vs Rexa S2 guide compares the whole REXA range.

Is vaping better than smoking? What the research says
For adult smokers, vaping is much less harmful than smoking, but it is not harmless. The UK government evidence update found that in the short and medium term, vaping poses a small fraction of the risks of smoking, and that long term effects still need more study. You can read the Nicotine vaping in England 2022 evidence update. A 2025 Cochrane analysis of trials found that nicotine vapes help more people stop smoking than nicotine patches or gum, while noting that longer studies are needed. It is on PubMed Central. The NHS has a practical page on vaping to quit smoking.
The simple rule: if you smoke, switching fully to a vape is a better choice than carrying on smoking. If you do not smoke, do not start. Nicotine is addictive. Our products are for adults 18 and over only.
