Today we're taking a closer look at the new VOOPOO ARGUS G4 and ARGUS G4 Mini. We’ll cover both devices in a single review since they share the same platform and, more importantly, the same new Multi-Ohm cartridge system. I've been using both devices for roughly a month, and in this review I'll share my personal experience with them. Before getting started, I'd like to thank VOOPOO for sending these devices for review and for their continued support of the ECF community.

Let's get started.

The first thing I want to talk about is the feature that I've been asked about the most over the last few weeks: the new Multi-Ohm cartridge system. Both devices come with VOOPOO's new ARGUS Multi-Ohm cartridge, and honestly, this is one of the most interesting innovations I've seen in the pod market in quite a while.

The concept itself is actually pretty simple. Inside the cartridge there are two separate coil sections: one rated at 0.7Ω and the other at 1.0Ω. By simply flipping the pod, you select which coil is active. The 0.7Ω and 1.0Ω modes can be used across the ARGUS pod family, but what makes the ARGUS G4 special is its three-pin design.

The device uses a positive-negative-positive electrode arrangement. Thanks to this setup, a double click of the button allows the device to activate both coil sections simultaneously. When this happens, the two coils are effectively connected in parallel, resulting in a combined resistance of approximately 0.4Ω. In other words, the same cartridge can provide 0.4Ω, 0.7Ω, and 1.0Ω vaping experiences depending on how you use it. I'll come back to this in more detail later in the review.​

The first thing I noticed was the weight. Compared to the ARGUS G3, the G4 feels noticeably heavier. The version I received is the zinc alloy model, which weighs around 85g. Aluminum alloy versions are also available and weigh approximately 65g. Depending on the color option, VOOPOO offers both aluminum alloy models with a zircon sandblasted finish and zinc alloy models with leather panels. You can see which colors use which materials in the image below.​

To be honest, the extra weight didn't bother me at all. In fact, it makes the device feel more premium in the hand. Having used the G3 extensively, I can confidently say that the G4 feels like a significant step up in overall build quality.

Another improvement I immediately noticed is stability when standing upright on a desk. One of my complaints about the G3 was that it could tip over rather easily. G4 largely fixes this issue. It stands much more securely and doesn't fall over every time a fly passes by.

The airflow control is located on the back of both devices and works very well. Unlike some pod systems where airflow adjustments barely make any difference, the airflow changes here are clearly noticeable.

MTL users should be very happy with the available range. Even though it doesn't get quite as tight as my ARGUS P3, it can still provide a draw tighter than a traditional cigarette when fully closed.​

On the G4, the display is bright, sharp, and easy to read. The menu system is straightforward as well. Three clicks adjust wattage, five clicks enter the menu, a long press confirms selections, and a double click activates or disables the 0.4Ω mode.

The G4 Mini takes a simpler approach by replacing the display with VOOPOO's Energy Bar system. Personally, I think this makes sense for users who prefer a more straightforward device. The LED bars indicate battery level and also change color depending on which resistance mode is active. Green indicates 0.7Ω mode, while white indicates 1.0Ω mode. Each of the four bars represents roughly 25% battery capacity.

The Mini is available only in aluminum alloy and weighs just 56g. It is slightly taller than the previous G3 Mini. I've included a comparison photo below showing the G2 Mini, G3 Mini, and G4 Mini side by side.​

This is unquestionably the headline feature of these devices. VOOPOO has genuinely tried something different here. When I first heard about the Multi-Ohm concept, I assumed it might be more of a marketing feature than something genuinely useful. After using it daily, I can honestly say I was wrong. In real-world use, it turns out to be surprisingly practical. For example, in the mornings throat hit often feels stronger to me, so I usually start the day using the 0.7Ω setting. Later in the day, when I want a tighter draw and a more cigarette-like vaping experience, I simply flip the pod and switch to the 1.0Ω side.

And then there's the 0.4Ω mode on the G4. Let's say a sudden nicotine craving hits and you feel like producing a bit more vapor, but your DTL setup isn't with you. You can quickly activate the 0.4Ω mode on the ARGUS G4, open the airflow fully, enjoy a short RDL session, and then switch right back to your normal MTL setup. Sounds pretty nice, doesn't it? That level of flexibility from a single pod is genuinely convenient. I've been using the ARGUS Top Fill V2 cartridges for roughly a year and a half, and this is the first new cartridge system that has actually convinced me to switch.

Another advantage is that these cartridges remain compatible with the entire ARGUS pod family. The 0.7Ω and 1.0Ω modes can be used on other ARGUS pod devices as well. The system is also beginner-friendly. Instead of wondering whether to buy a 0.7Ω or a 1.0Ω pod, both options are already included. If you prefer a tighter MTL draw, slightly cooler vapor and a more traditional cigarette-like experience, simply use the 1.0Ω side. If you want a slightly looser draw and stronger flavor intensity, use the 0.7Ω side. If you want to move closer to RDL territory, activate the 0.4Ω mode on the G4. Normally, achieving this kind of flexibility would require carrying multiple pods or even multiple devices. Here, it's all available from a single cartridge.

I also like the physical design of the new cartridge. Compared to the older V2 pods, the body is slightly longer and the capacity has increased by 0.5ml. This solves an issue I occasionally experienced with some thicker V2 coil structures where e-liquid could take a while to move across the pod during filling. Leak resistance has been excellent. During my testing period I experienced no leaking whatsoever. Flavor performance has also been very impressive. Marketing claims aside, I can comfortably say that the new cartridge performs at least as well as the excellent Top Fill V2 pods in terms of flavor quality. I've been using these cartridges for about a month, although I rotate several devices throughout the day, so I haven't pushed a single cartridge to the end of its lifespan yet. Performance remains virtually unchanged so far.

My personal expectation is that these cartridges may actually last longer than the V2 versions. VOOPOO explained that alternating between the two coil sections can help distribute thermal stress instead of continuously stressing a single coil. While e-liquid composition remains the biggest factor affecting coil lifespan, the Multi-Ohm approach may provide a small longevity advantage. One last note: seeing the cartridge displayed individually in the yellow box above might make it look like they're going to be sold 1 piece. That's not the case. Retail packs will still contain three cartridges. The single cartridge shown was simply a sample provided for testing.​

Power & Performance

Both devices use a 1650mAh battery, which has proven more than sufficient for daily use. I know some people may look at the specification sheet and wish for 2000mAh or even larger batteries, but battery optimization here is genuinely impressive. Unlike some devices that noticeably weaken once battery levels drop, I experienced consistent performance all the way down to low battery levels. The G4 offers up to 35W of output power, while the G4 Mini reaches 30W. For devices primarily designed around MTL and light RDL usage, those power levels are more than adequate. The G4 also supports 2A fast charging and reaches a full charge in roughly 45 minutes. The Mini charges slightly slower at 1.5A, but I never found that to be an issue during everyday use.​

It's been quite a while since I've seen a genuinely new idea in the pod market. Most manufacturers seem content releasing essentially the same device with new colors and minor specification changes. VOOPOO has actually introduced something different here, and more importantly, something genuinely useful. For me, the ARGUS G4 is the standout device. The 0.4Ω mode, adjustable wattage, and display make it significantly more versatile than the Mini. The G4 Mini is still an excellent option for users who prefer something lighter, simpler, and more pocket-friendly. Most importantly, after using the ARGUS Top Fill V2 pods for a long time, this is the first cartridge system that has genuinely convinced me to switch.

In my opinion, this is one of the most interesting updates VOOPOO has made to the ARGUS lineup in recent years.
