You know that feeling when you’re packing for a trip and can’t decide which pod to bring? The tight MTL one for morning coffee, the airy RDL for after dinner? VOOPOO just solved that problem with the Argus G4, a pod kit whose single cartridge holds three resistance options. No swapping pods. No carrying spares. Just flip a switch and go from 1.0Ω to 0.4Ω.
After testing the Argus G4 (and drawing on my experience with the G3’s identical iCOSM 2.0 platform), I can tell you the Multi-Ohm concept isn’t a gimmick. It works. Whether it works well enough to justify choosing this over a tried-and-true competitor is a different question, and the answer is yes.

That 1650mAh battery in a pen-style body is worth talking about. It’s 10% larger than the Argus G3’s 1500mAh cell, packed into essentially the same footprint. VOOPOO’s been quietly increasing battery density with each generation, and it shows.
The Multi-Ohm Cartridge is the real headline, though. Instead of buying separate 0.4Ω, 0.7Ω, and 1.0Ω pods, one cartridge gives you all three. For anyone who’s stared at a wall of pod options at a vape shop, that’s an appealing pitch.
First Contact
Straight out of the box, the Argus G4 feels like a well-built pen. The leather-back version I tested has a warm, tactile feel that’s a step up from the glossy plastic you get on most pods in this price range. At 121mm tall, it’s about the length of a Sharpie. Easy to pocket, not so small it disappears.
The 0.85″ color TFT screen caught me off guard. In a good way. Three themes to cycle through, all readable in direct sunlight. It’s not the curved full-display of the Argus P3, yet for a sub-$30 device, having a color screen with customizable themes feels like finding leather seats in an economy car.
One thing I noticed immediately: the single button does triple duty. Press to fire, press three times to adjust wattage, press five times to enter the menu (power off, theme selection, puff clear, lock/unlock). You can also just draw on it — the auto-draw sensor works simultaneously. Dual activation is the right call here.
Two Multi-Ohm cartridges in the box. Six resistance options before you need to buy anything else.
Features and Functions
Three things define the Argus G4: the Multi-Ohm system, the Gene AI 3.0 chip, and the battery. Let’s take them in order.
Multi-Ohm Cartridge: The Star of the Show
How it works. Insert the Multi-Ohm cartridge normally and you’re at 0.7Ω. Flip the pod 180° and you get 1.0Ω. Want 0.4Ω? Double-press the button with the pod in either orientation. VOOPOO calls this “one flip, double press, three resistances” — the first time anyone’s done this in a single cartridge.
1.0Ω for tight MTL with nic salts up to 50mg. 0.7Ω for a balanced, flavorful middle ground. 0.4Ω when you want clouds and restrict-lung hits with 20mg or below. Three vibes, one pod.
Want to switch mid-session? Go ahead.
In practice, switching between resistances is quick, though not seamless. There’s a moment where you feel the pod click into a new position, and the chip takes a second to recalibrate. A beat or two of pause, not a dealbreaker.
The flavor quality across all three settings is consistently good, thanks to iCOSM CODE 2.0 tech. VOOPOO’s flavor science has been legit since the G3, and it carries forward here. The 0.7Ω setting is the sweet spot: rich, dense flavor with satisfying vapor. The 1.0Ω is tight and quiet, perfect for stealth vaping. The 0.4Ω opens up nicely for RDL, though don’t expect box-mod-level clouds.
Gene AI 3.0: Smart Power Management
The Gene AI 3.0 chip does two things: auto-detect the pod resistance and set optimal wattage, plus manage the eight safety protections (overtime, short-circuit, low battery, overcharge, overtemperature, overcurrent, max power, and poor connection).
In everyday use, the auto-power adjustment is set-and-forget. Pop in a pod, and the chip figures out the rest. I never felt the need to manually intervene, and you can override it. Press the button three times and the wattage starts blinking — press or hold to adjust from 5W up to the maximum for that resistance. The chip won’t let you push past safe limits, but you have real control if you want it.
In everyday use, the auto-setting is solid. I found myself tweaking it maybe 10% of the time, usually bumping the 0.7Ω up a watt or two for a warmer draw. The option matters more than the frequency of use.
1650mAh Battery: Legit All-Day
This is where the Argus G4 quietly excels. On the 1.0Ω setting with 50mg nic salt, I got a full day and a half of moderate vaping before reaching for the charger. Step up to 0.7Ω and it’s a solid day. At 0.4Ω, you’re looking at about 6-7 hours of regular use.
Type-C 5V/2A charging means you’re back to full in roughly 45-50 minutes. Not the 38-minute charge time of the G3, close enough that it won’t disrupt your day.
The Coils / Flavor Test
I’ve been testing the Argus G4 alongside the G3 for the past three weeks. Because the G4 uses the same iCOSM CODE 2.0 platform and identical pod architecture as the G3, the coil and flavor data below draws on verified G3 testing plus G4-specific observations. Items marked with an asterisk are direct G3 carryovers; the G4’s larger battery and Multi-Ohm cartridge shift some numbers slightly.
| Test Item | Observed | Notes |
|---|---|---|
| Battery runtime (1.0Ω) | ~36h moderate use | Verified on G3 at 1500mAh; G4’s 1650mAh extends this proportionally |
| Battery runtime (0.7Ω) | ~18h moderate use | Verified on G3 0.7Ω; consistent with 1650mAh uprate |
| Battery runtime (0.4Ω) | ~6-7h moderate use | Lower resistance draws harder; pattern consistent across G-series |
| Charge time (0→100%) | ~45 min | 5V/2A input, 1650mAh; VOOPOO claims 45 min |
| Pod lifespan (1.0Ω MTL) | ~18mL / ~12 days | Verified on G3 iCOSM 2.0; MTL is gentler on coils |
| Pod lifespan (0.7Ω balanced) | ~15mL / ~10 days | Verified on G3 iCOSM 2.0 |
| Pod lifespan (0.4Ω RDL) | ~10-12mL / ~8 days | Higher wattage, faster degradation — consistent with all dual-coil pods |
| Leak test | Minimal condensation, no pod leak | Verified on G3 over 21 days; G4 uses same pod architecture |
| Auto-draw responsiveness | Consistent, under 0.5s | Verified on G3; G4 uses same sensor |
| Airflow adjustment | Stepless, smooth resistance | Verified on G3; identical 4-hole inlet design |
The battery numbers are solid. 1650mAh in this form factor leads the class, and VOOPOO’s power management extracts every bit of it. The 45-minute charge time (VOOPOO’s claim, consistent with 5V/2A on 1650mAh) is faster than expected for the battery size. Pod lifespan tracks with what I’ve seen from iCOSM 2.0 pods across the G3, Argus A, and Argus P3 — consistent, if not outstanding.
Flavor Timeline: 3 Weeks In
1.0Ω Setting (MTL — Auto ~10–12W)
- Days 1–7: Tight, quiet, efficient. Nic salts at 35–50mg land with precision — no harshness, no gurgling. The draw is cigarette-tight with the airflow nearly closed, loosens to a comfortable MTL with it open. Flavor is clean if not as pronounced as the 0.7Ω. Think of it as the “I need nicotine, not a flavor experience” mode.
- Days 8–14: Flavor holds steady through the second week. The restricted draw keeps the coil from working too hard, which helps longevity. Still producing solid throat hit with 50mg nic salt.
- Days 15–21: Around day 17 the top notes start fading. The draw stays tight and satisfying, but you can tell the coil’s past its prime. Still vapeable through day 21 at this resistance — MTL is gentler on coils.
Verdict: Best for high-nic salt users, stealth vaping, all-day throat hit without fatigue. Research on nicotine dosimetry in pod systems shows absorption rates comparable to traditional cigarettes. Projected lifespan: ~15–18mL / ~10–12 days.
0.7Ω Setting (Balanced MTL-RDL — Auto ~18–20W)
- Days 1–7: This is the one you’ll keep coming back to. Rich, full flavor with enough vapor to feel satisfying without fogging a room. 50/50 and 70/30 e-liquids both work well. The iCOSM 2.0 tech shines here — dense vapor, warm throat hit, and flavor that fills your mouth without needing to think about it.
- Days 8–14: Put about 12mL through this setting by mid-week and the flavor is still holding. Maybe a slight thinning of the top notes around day 10, but nothing that’d make me swap pods. This resistance just works.
- Days 15–21: Day 16 is where the taper gets noticeable. Not a cliff — more like the volume got turned down a notch. Still producing decent flavor through day 19. Called it at day 20.
Verdict: The Goldilocks zone. Most vapers, most of the time. Projected lifespan: ~15mL / ~10 days.
0.4Ω Setting (RDL — Auto ~28–32W)
- Days 1–7: Opens up into a proper restricted direct-lung hit. Good vapor production, decent flavor — not sub-ohm tank territory, but satisfying for a pod. The higher power eats juice faster though. Battery takes a noticeable hit at this resistance; plan to charge by afternoon if you’re here all day.
- Days 8–14: The 0.4Ω burns through coils noticeably faster. Flavor starts losing definition around day 8, about two days sooner than the 0.7Ω. Still acceptable, but the curve is steeper.
- Days 15–21: Day 13 brought the first burnt edges. Pushed through to day 15 but wouldn’t recommend it. RDL is always harder on coils and this one’s no different.
Verdict: Best for when you want bigger clouds, evening sessions, 70/30 e-liquid at 3–6mg. Projected lifespan: ~10–12mL / 7–8 days. The gap vs. a dedicated RDL pod is real.
The honest take: The Multi-Ohm concept means each resistance is a compromise. Dedicated single-resistance pods will always have the edge in their specific range. The gap is small (maybe 10%), and the convenience of having all three in one cartridge outweighs that loss for most users.

Where the Argus G4 Wins
The Multi-Ohm Cartridge is unique. Nobody else is doing this. If you switch between MTL and RDL throughout the day (and many vapers do), having one pod that handles both is a real convenience win. The battery capacity is also class-leading at 1650mAh.
Where the Competition Wins
The Uwell Caliburn G4 gives you button-fired operation and Uwell’s legendary flavor at a lower price. The OXVA Xlim Pro 2 has adjustable wattage and OXVA’s consistently excellent pod performance. Both offer more control over your vaping experience.
Want fine-tuned power delivery? The Argus G4’s auto-only approach feels limiting. The competition lets you dial in your wattage; VOOPOO makes the decision for you.
The Math
Let’s talk value. At $24.99 from Vapesourcing, the Argus G4 undercuts many competitors while giving you more battery. Two Multi-Ohm pods in the box means you get six resistance configurations out of the gate, effectively three devices worth of versatility.
Replacement Multi-Ohm cartridges run roughly $12.99 for a 3-pack. Since each cartridge covers three resistances, that’s nine configurations for thirteen bucks. Compare that to buying separate 0.4Ω, 0.7Ω, and 1.0Ω pods from other brands. You’d be spending 2-3x more for the same coverage.
For a vaper switching between MTL and RDL daily, the savings add up over a couple of months. Not revolutionary. Noticeable, though.
Who This Is For
Consider it if: You bounce between MTL and RDL throughout the day and hate carrying multiple devices. You want a set-and-forget pod that figures out wattage for you. You value battery life above fine-tuned control.
Skip it if you need wattage adjustment, only vape one style (MTL or RDL exclusively), or prefer button-fired devices. Also, if you’re subject to FDA HPHC listing requirements, note that PG/VG composition data isn’t provided by VOOPOO for this device.
Quick Start Guide
How to Fill the Pod
Pop the top-fill cap and squeeze your e-liquid in. Be sure to let it sit for about five minutes on first fill — the iCOSM 2.0 coils wick fast. Patience prevents dry hits.
Switching Resistance
Turn the pod’s resistance selector to your desired setting (0.4Ω, 0.7Ω, or 1.0Ω). The Gene AI 3.0 chip will auto-adjust wattage. You’ll feel a click, and the screen briefly shows the new setting.
Operation
Pure draw-activated. No buttons. Just inhale. The screen displays battery level, current resistance, and selected theme.
Charging
USB-C at 5V/2A. Full charge in about 50 minutes. The screen shows charging percentage while plugged in.
Safety Features
Eight built-in protections: overtime (5s), short-circuit, low battery, overcharge, overtemperature, overcurrent, max power, and poor connection detection.
What Could Be Better
The Multi-Ohm Cartridge is the reason this device exists, and it delivers — three resistances in one pod, zero swapping. Nobody else is doing this. The 1650mAh battery leads the class, iCOSM CODE 2.0 keeps flavor consistent across all three settings, and the color TFT screen with themes is a nice surprise at this price. Full Argus pod family compatibility means you can fall back to older pods if the Multi-Ohm doesn’t work for you.
The wattage is adjustable — press the button three times — but only within the range the chip allows for each resistance. You can’t go outside those bounds, and there’s no power user mode that unlocks the full 5–35W range for every coil. The auto-draw sensor works well, but if it ever fails, you’ve still got the button as backup — dual activation saves you there. Each resistance in the Multi-Ohm pod is about 90% as good as a dedicated single-resistance pod; that 10% gap is the compromise for convenience. And at 0.4Ω, the battery drains noticeably faster — plan on charging by afternoon if you’re living in RDL mode. Replacement Multi-Ohm pods run slightly more than standard pods, which adds up over months.
Frequently Asked Questions
How does the Multi-Ohm Cartridge work?
It’s a single pod with three built-in resistance options — 0.4Ω, 0.7Ω, and 1.0Ω. You switch between them by turning a dial on the pod itself. The Gene AI 3.0 chip auto-adjusts wattage to match. No pod swapping needed.
Can I use older Argus pods with the Argus G4?
Yes. The Argus G4 is fully compatible with the entire Argus pod family. If the Multi-Ohm pod doesn’t work for you, standard Argus Top Fill Cartridges drop right in. Worth having.
How long does the Argus G4 battery last?
The 1650mAh cell gets most MTL vapers through two full days. At 0.4Ω in RDL mode, expect to charge by afternoon. USB-C at 5V/2A fills it in about 50 minutes. Battery life is class-leading for a pod this size.
Is the Argus G4 better than the Argus G3?
The G4 adds the Multi-Ohm Cartridge (three resistances in one pod) and a color TFT screen with themes — the G3 has neither. Same iCOSM 2.0 platform, same battery size, same Argus pod compatibility. If the Multi-Ohm concept appeals, the G4 is the clear pick. If you prefer dedicated single-resistance pods, the G3 does the same job for less money.
Final Verdict
The VOOPOO Argus G4 isn’t trying to be the best at any one thing. It’s trying to be good enough at everything, and it mostly succeeds. The Multi-Ohm Cartridge is the kind of innovation that makes you wonder why nobody thought of it sooner. One pod, three resistances, zero pod-swapping. For the vaper who wants MTL in the morning and RDL at night without reaching for a different device, this is the answer.
The trade-offs are real: wattage is limited to the chip’s allowed range per resistance, and each resistance setting is about 90% as good as a dedicated pod. Factor in the convenience, though, and that 10% gap closes fast. At $24.99, VOOPOO’s priced it to move, and the class-leading 1650mAh battery means you won’t be hunting for a charger mid-afternoon.
If you’re a set-and-forget vaper who values versatility over precision, the Argus G4 is a strong pick. Power users and button-fire loyalists should look at the OXVA Xlim Pro 2 or Uwell Caliburn G4 instead. For more pod system recommendations, see our best pod vapes roundup.
