OXVA and Vaporesso both make 30W refillable pod kits that fire when you draw, and the biggest difference between them is the pod. An OXVA Xlim takes Xlim top fill cartridges, a Vaporesso XROS takes COREX pods, and the two do not swap.
The Xlim kits sit in OXVA Xlim series, with OXVA's dual mesh NeXlim kits alongside them.
Every OXVA kit and pod is in OXVA vapes range.
The XROS is Vaporesso's pod kit line, and every model is in our Vaporesso XROS series.
The rest of Vaporesso's kits, pods and coils are in our Vaporesso vapes range.
The figures below come from OXVA and Vaporesso. Where something is our own view or our own testing, it says so.
Is OXVA Better Than Vaporesso
Neither is better across the board. They split on how you set the power, the pods and the extras, so the right one depends on what you want from the kit.
Setting the power: on the Xlim Pro 3 you set any wattage from 5 to 30W with any pod. On the XROS 6 and XROS Pro 2 you set a wattage only on the 0.4 ohm pod, and pick Power, Normal or Eco on the others.
Pods: Xlim cartridges come in 0.4, 0.6, 0.8 and 1.2 ohm. XROS pods add a 1.0 ohm, from 0.4 to 1.2 ohm.
Filling: both fill from the top. On an Xlim you lift a silicone plug with the pod still in the kit, and on an XROS you snap off the mouthpiece.
Priming: Vaporesso build a 60 second Smart Prime into the XROS 6 and XROS 6 Mini. OXVA say to leave a fresh Xlim pod for 5 to 8 minutes.
Power: the Xlim and XROS kits top out at 30W. OXVA's NeXlim kits go to 40W.
OXVA also make the VPrime for a direct lung draw, and Vaporesso make the Luxe and Armour ranges. This guide compares the Xlim and NeXlim with the XROS.
OXVA Xlim vs Vaporesso XROS
Each OXVA pod kit has a close match in the XROS range. These are the pairs people weigh up:
Xlim Pro 3 vs XROS Pro 2
These are the two flagships. The XROS Pro 2 has the bigger battery and Super Pulse, and the Xlim Pro 3 has the bigger screen, a smaller body and a set wattage on every pod.
Both pulse the power through the draw. OXVA say the Photon chip keeps over 80% of the flavour at 20% battery. Vaporesso brought Super Pulse down from their tank mods, for a faster ramp at the start of the inhale.
Pick the XROS Pro 2 for battery life. Pick the Xlim Pro 3 for a smaller kit, the bigger screen, or a set wattage on a 0.6 or 0.8 ohm pod.
Xlim Pro 3 vs XROS 6
The XROS 6 is Vaporesso's full-size screen kit and the closest match to the Pro 3 on size.
The XROS 6 has the bigger battery, faster charging and the lighter body. The Pro 3 has the bigger screen and lets you set a wattage on any pod.
Xlim Go 2 vs XROS 6 Mini and XROS 5 Mini
All three have no buttons and no screen: you fill the pod and draw. They suit anyone moving to a refillable kit for the first time.
The Go 2 is the lightest and comes with the tighter 0.8 ohm pod for nic salt. The XROS 6 Mini has the biggest battery of the three and a 60 second prime, and the XROS 5 Mini is the only one with a cable in the box.
NeXlim 2 vs Vaporesso XROS
The NeXlim 2 is OXVA's dual mesh kit, and it goes to 40W where every XROS stops at 30W. Its closest XROS on battery is the Pro 2, with 2000mAh each.
The NeXlim 2 has more power and faster charging. The XROS Pro 2 is lighter, has a fire button and takes a 0.4 ohm pod.
OXVA Pods vs Vaporesso XROS Pods
Pods do not cross over between the brands, or between Xlim and NeXlim, so the pods you already own can decide it for you.
Vaporesso give no pod life for COREX 3.0. In our experience an XROS pod lasts about one to two weeks with everyday vaping. OXVA rate a NeXlim UNITECH 3.0 cartridge at up to 30 refills in Eco and 20 in Boost.
Spare Xlim V3 pods fit every Xlim kit.
Spare XROS COREX 3.0 pods fit every XROS kit.
Spare NeXlim pods fit every NeXlim kit.
What Customers Say About OXVA and Vaporesso
These are the star ratings customers have left on the product pages, all from verified buyers. The scores sit close together, so the comments tell you more than the stars.
Xlim Pro 3: build quality and flavour come up most. Customers moving up from the Xlim Pro 2 mention the bigger screen and longer battery life, and one liked having the fire button for anyone the auto-draw sensor doesn't suit. One heavy vaper found the battery ran down too quickly.
XROS Pro 2: battery and price come up most. One customer found the battery life shorter than expected, and two of the reviews at three stars or below report a pod leaking.
Xlim Go 2 and XROS 5 Mini: customers call both simple and easy to carry. XROS 5 Mini owners talk about battery life more than anything else, and Xlim Go 2 owners about flavour. One Go 2 owner points out that no charging cable comes in the box.
Pods: flavour is the main praise for both Xlim V3 and XROS COREX 3.0 pods. The complaints are about the odd pod in a pack: a COREX pod that leaks, or an Xlim pod that tastes burnt early.
OXVA or Vaporesso: Which Should You Buy
Xlim Pro 3 if you want to set a wattage on any pod, or you already own Xlim pods.
XROS 6 for the bigger battery, faster charging and a 60 second prime.
NeXlim 2 or XROS Pro 2 for a 2000mAh battery: the NeXlim 2 for 40W and 3A charging, the XROS Pro 2 for a lighter kit with a fire button.
Xlim Go 2 or XROS 6 Mini for nothing to set: the Go 2 is lighter, the XROS 6 Mini has the bigger battery.

Vaporesso's own is DojoLiq nic salt, with the Dojo Blast flavours in a bottle.
