The Eleaf iVeni and VOOPOO Argus G4 are both compact pod-style devices, but they split their strengths in different directions. One leans on battery capacity, the other on power output, so the right pick depends on what matters more day to day.
This comparison sticks to the confirmed specs and review notes for each device, calling out where the data supports a clear winner and where it does not.

Battery
The VOOPOO Argus G4 wins the battery category on the strength of its 1650 mAh cell versus the 1100 mAh unit in the Eleaf iVeni, a meaningful gap that should translate into longer use between charges. The iVeni does charge to 80% faster, in 30 minutes against 35 minutes for the Argus G4, but that quicker top-up doesn’t offset the smaller overall capacity it’s topping up. Both use an internal battery with a 2 A charge current, so there’s no difference to weigh there.
Performance
Eleaf iVeni takes the performance category on max output, delivering 40 W compared to the Argus G4’s 35 W, giving it a bit more headroom for users who want a stronger throw of vapor. Coil resistance options are listed differently between the two (fixed values of 0.4Ω, 0.6Ω, 0.8Ω, and 1.2Ω for the iVeni versus a broad 0.4–3.0Ω range for the Argus G4), but the two ranges aren’t directly comparable, so that detail sits outside the wattage decision. The Argus G4 also lists variable wattage as a confirmed feature while the iVeni’s is not stated, though this wasn’t factored into the category winner.
Convenience
Convenience comes out a tie. The VOOPOO Argus G4 is notably lighter at 65 g versus 88 g for the Eleaf iVeni, which helps for pocket carry, but the iVeni counters with its faster charge time. Both have a display screen, adjustable airflow, and a USB-C style charging port, so the everyday handling experience is a wash once these trade-offs are weighed against each other.
The Eleaf iVeni suits vapers who prioritize higher max output and a faster charge time over a larger battery.
The VOOPOO Argus G4 suits vapers who want longer battery life and a lighter device to carry around.
The verdict
Neither device comes out ahead across the board. The VOOPOO Argus G4 leads on battery capacity, the Eleaf iVeni leads on max output and charge speed, and convenience is a genuine tie once weight and charging times are weighed against each other. Choosing between them comes down to whether longer battery life or higher wattage matters more for a given user.
