The Eleaf iVeni and OXVA XLIM 3 Ultra are both compact pod vapes with displays and adjustable airflow, but they split on the two specs that matter most day to day: battery size and output power. Neither device sweeps the comparison, so the right pick depends on which trade-off matters more to you.
Below, each category winner is based strictly on the spec sheet and review notes, with plain explanations of why the numbers land where they do.

Battery
The OXVA XLIM 3 Ultra wins on battery with a 1500 mAh cell compared to the Eleaf iVeni’s 1100 mAh, a real-world gap of 400 mAh that should translate into more vaping time between charges. Both devices share the same charge time to 80% (30 minutes) and the same 2 A charge current, so the OXVA’s advantage comes purely from having more capacity to work with, not from charging faster.
Performance
The Eleaf iVeni takes performance on the strength of its 40 W max output versus the OXVA XLIM 3 Ultra’s 30 W, a 10 W ceiling advantage that gives it more headroom for denser vapor and flavor at higher settings. Both devices offer the same set of coil resistance options (0.4Ω, 0.6Ω, 0.8Ω, 1.2Ω), so the difference in ceiling wattage is the deciding factor here rather than coil choice.
Convenience
Convenience is a tie: both devices have a display screen, adjustable airflow, identical charge times, identical charge current, and nearly identical weight (88 g vs 90 g). The OXVA XLIM 3 Ultra lists variable wattage and a zinc alloy build with an IML/PU finish, while the Eleaf iVeni does not state these details, but that is a gap in available information rather than a demonstrated difference, so it does not tip the category.
The Eleaf iVeni suits vapers who prioritize higher maximum output for stronger vapor production over battery longevity.
The OXVA XLIM 3 Ultra suits vapers who prioritize longer battery life between charges over maximum wattage.
The verdict
There is no single overall winner here — the Eleaf iVeni and OXVA XLIM 3 Ultra each lead in one core area, and convenience comes out even. The OXVA XLIM 3 Ultra’s larger 1500 mAh battery suits anyone who wants fewer charging interruptions, while the Eleaf iVeni’s 40 W ceiling gives it an edge for those who want more power on tap. Everything else — display, airflow adjustment, charge speed, charge current, and weight — is close enough that it should not factor heavily into the decision.
