The 10 Best Smart Vape Devices

The integration of advanced chipsets and high-definition displays has transformed the humble e-cigarette into the best smart vape category we see today. Marcus, Jamal, and I gathered at our testing lab to evaluate how these "smart" features—ranging from touch screens to AI-driven power curves—actually impact daily vaping. We moved beyond simple puff counts. Our process involved tracking battery efficiency on digital displays, testing "turbo" modes during Marcus’s high-stress sessions, and evaluating Jamal’s commute-heavy usage of pocket-friendly smart pods.

This roundup focuses on devices that offer intelligent feedback. We spent weeks rotating ten specific units, noting how accurate the digital liquid indicators really are and if the "smart modes" actually prevent dry hits. While Marcus pushed coils to their absolute thermal limits to test durability, Jamal focused on the user interface and pocket safety. Dr. Walker reviewed our notes to ensure we didn't overstate safety, reminding us that technology does not eliminate respiratory risks associated with nicotine.

We aimed to separate gimmicks from genuine utility. A screen that drains the battery without adding function is useless. We looked for devices where the "smart" element improved consistency, flavor accuracy, or maintenance management. What follows is our detailed breakdown of the ten most capable smart vapes currently on the market, tested through our rigorous, standardized team workflow.

Our Verdict: What’s the Best Smart Vape

After extensive testing, the Vaporesso XROS 4 stands out as the Best Overall Smart Vape.

While disposable options like the Geek Bar Pulse X offer flashy screens, the XROS 4 integrates "smart" technology where it counts: the COREX 2.0 chipset and precise power management. It bridges the gap between portability and performance perfectly. The device detects coil resistance instantly, adjusting output to prevent the burning Marcus often experiences with manual settings. For Jamal, the screen provided necessary status updates without being obtrusive during travel. It offers a sustainable, refillable solution that outperforms disposables in flavor fidelity and long-term cost. It is the logical choice for adult users wanting reliability over novelty.

What We Tested and How We Tested It

Our team established a rigorous protocol to evaluate these devices beyond their marketing claims. We specifically targeted the "smart" functionalities, testing whether screens and chips added value or just drained power.

Flavor Integrity and Consistency:

Marcus and I tested each device using a standardized 70/30 VG/PG liquid for refillables and the stock flavors for disposables. We noted flavor separation at full charge versus low battery. We checked if "smart modes" maintained consistent voltage output as the battery depleted.

Intelligent Features and UI:

Jamal focused on interface usability. We tested screen visibility in direct sunlight and pitch darkness. We evaluated the accuracy of "e-liquid level" indicators on disposables by weighing the devices empty versus full. We triggered safety cutoffs intentionally to test chipset response speeds.

Battery Efficiency and Charging:

We logged charge times from 0% to 100% using a dedicated power meter. We monitored heat generation during charging, a key concern for Dr. Walker regarding battery safety. We compared the manufacturer's puff ratings against our actual usage logs.

Durability and Portability:

Marcus conducted stress tests, including drop tests from waist height onto carpet and wood. Jamal carried each unit in tight pockets with keys to check for screen scratching and accidental firing. We assessed leak resistance by leaving devices on their sides overnight.

Medical Context:

Dr. Walker reviewed our feedback on airflow and throat hit. He ensured we noted any excessive heat at the mouthpiece that could cause irritation. He verified that our descriptions of nicotine delivery remained subjective and did not veer into medical efficacy claims.

Best Smart Vapes: Our Testing Experience

1. Vaporesso XROS 4: Best Overall Smart Vape

Why We Picked It

I started using the XROS 4 during a busy week of editing, needing something that required zero fiddling. The "smart" aspect here is subtle but powerful; the Corex 2.0 tech detects the pod resistance instantly. Marcus tried to trick it by swapping between 0.4Ω and 0.8Ω pods rapidly, but the device adjusted the wattage profile immediately every time. Jamal appreciated the screen that isn't a billboard—it just shows what you need.

The draw experience is exceptionally refined. I tested the "Corex" heating tech with a complex vanilla custard tobacco e-liquid. On the inhale, the warmth is immediate but controlled. The flavor notes separate beautifully; I could taste the vanilla distinct from the tobacco. Marcus noted that even when chain-vaping the 0.4Ω pod, the flavor didn't collapse into a hot mess. The throat hit on the 0.8Ω pod is crisp and defined, satisfying that morning craving without harshness. It feels calibrated, not just raw power.

Pros & Cons

2. Geek Bar Pulse X: Best Smart Disposable Vape

Why We Picked It

This device caught Jamal's eye immediately with its curved 3D screen wrapping around the body. It’s the "smartest" disposable we found simply due to the visual data it provides. I took this to a weekend event to test the "Pulse Mode." The screen animations are flashy, which Dr. Walker noted might appeal to the wrong demographic, but purely functionally, the juice level accuracy was spot on.

Using "Pulse Mode" changes the draw drastically. The airflow opens up, and the dual mesh coils fire hard. The vapor is warm, almost hot, which Marcus loved for the intensity. I found the "Regular Mode" better for flavor duration. With the "Sour Apple Ice" flavor, the draw is sugary and cold. The inhalation feels thick; it coats the tongue instantly. The throat hit is masked by the cooling agent, making it dangerously easy to chain vape. The smart screen showing the battery percentage dropping in real-time helped me manage my charging habits.

Pros & Cons

Pros	Cons
First-of-its-kind curved 3D display	Disposable nature creates electronic waste
Pulse Mode doubles vapor output instantly	Bulky form factor for a disposable
accurate digital liquid and battery %	Pulse mode drains liquid very fast
High-current airflow is very smooth	Screen consumes battery power

Overall	4.7	Top-tier tech in a throwaway format.

3. Geekvape Aegis Legend 3: Best Smart Box Mod

Why We Picked It

Marcus insisted on this one. The "smart" feature here is the biosensing "Smart Lock." You pick it up, it unlocks; you put it down, it locks. No button combinations needed. I tested this feature while wearing gloves, and it struggled, but with bare hands, it was seamless. It solves the issue of pocket-firing entirely without user input.

This is a powerhouse. Marcus equipped it with a Z-Fli tank and 0.15Ω coils. The draw is massive—a full lungful of steam. Testing the "Smart Mode" (which limits max wattage based on coil resistance), I felt safe handing it to Jamal, who isn't a high-wattage vaper. The flavor is intense and warm. The airflow is loud, rushing in with turbulence that signifies power. The throat hit at 80W is a thump to the chest, exactly what high-power users chase. The AS Chip 4.0 delivers power instantly; there is zero ramp-up lag.

Pros & Cons

Pros	Cons
Palm recognition unlock is revolutionary	Heavy and bulky (dual batteries)
IP68 rating (Water/Dust/Shock resistant)	Palm lock fails with thick gloves
Instant firing speed	External batteries require separate charger
Smart mode protects coils from burning	Boxy design is not pocket friendly

KEY SPECS & FLAVORS

• Price: $65.00

• Device Type: Dual Battery Box Mod

• Smart Tech: AS Chip 4.0, Palm Recognition Lock

• Battery: Dual 18650 (Not Included)

• Power: 5W - 200W

• Modes: POWER, TR-S, ECO, SMART, BOOSTING, MEMORY

• Tank: Geekvape Z-Fli Tank

• Flavors: N/A (Open System)

Review Score

Metric	Score	Remarks
Flavor	4.8	Z-coils are legendary for rich sub-ohm flavor.
Throat Hit	5.0	Powerful and customizable via wattage.
Vapor Production	5.0	Cloud competition ready.
Airflow/Draw	4.9	Top airflow prevents leaks, very airy.
Battery Life	4.8	Depends on batteries, but Eco mode helps.
Leak Resistance	4.8	Top airflow design is virtually leak-proof.
Build Quality	5.0	Built like a tank, survives drops easily.
Ease of Use	4.5	Smart lock simplifies safety, but menus are deep.
Portability	3.5	Requires a bag or jacket pocket.
Overall	4.8	The smartest heavy-duty device available.

4. Uwell Caliburn G3 Pro: Best Display on a Pod Vape

Why We Picked It

I have always respected Uwell's flavor, but the G3 Pro takes the visual experience to a new level. The entire front is a screen. Jamal loved this for the commute; glancing down showed him exact puff count and battery. The "smart" aspect is the interface customization and dynamic UI that shifts based on usage. It feels like a modern gadget, not a smoking substitute.

Flavor-wise, Uwell’s "Pro-FOCS" technology remains elite. I tested the 0.4Ω cartridge. The draw is noticeably smoother than the G2. Inhaling brings a wet, saturated vapor that highlights the sweet notes in fruit liquids. It’s a restricted Direct Lung hit that feels airy yet flavorful. Marcus felt the 0.9Ω pod was better for a tighter, cigarette-like draw. The device automatically sets the wattage, but the smart button lets you override it easily if you want a warmer vape.

Pros & Cons

Pros	Cons
Stunning full-height dynamic display	Screen reduces battery life if always on
Pro-FOCS flavor tech is top-tier	Side button is sensitive to pressure
Accommodates both RDL and MTL styles	Glossy finish attracts fingerprints
3ml capacity is generous for a pod	0.4Ω coil runs hot after chain vaping

KEY SPECS & FLAVORS

• Price: $32.99

• Device Type: Refillable Pod Kit

• Smart Tech: Full-Screen UI, Dynamic Interface

• Battery: 1000mAh

• Power: Max 35W

• Pods: G3 Integrated Coil Cartridges

• Airflow: Adjustable slider

• Material: Zinc Alloy

• Flavors: N/A (Open System)

Review Score

Metric	Score	Remarks
Flavor	4.9	Wet, saturated flavor characteristic of Uwell.
Throat Hit	4.6	Smooth, less aggressive than the XROS.
Vapor Production	4.6	impressive clouds for a slim stick.
Airflow/Draw	4.7	versatile range from tight to loose.

Leak Resistance	4.7	Ultrasonic welding on pods prevents leaks.
Build Quality	4.8	Premium feel, heavy in the hand.
Ease of Use	4.7	Single button navigation is intuitive.
Portability	4.8	Slim enough for any pocket.
Overall	4.8	Visual flair meets exceptional flavor.

5. Raz DC25000: Best High-Capacity Smart Vape

Why We Picked It

Marcus brought this one to the table because of its sheer endurance. The "smart" feature includes a high-definition screen with animations and a brightness adjustment—something rare in disposables. We tested the "Boost Mode" extensively. The device manages power intelligently; even at 10% battery, the chip pulsed power effectively to keep flavor consistent, which is usually where disposables fail.

The draw on the Raz DC25000 is wide and airy. I tested the "Night Crawler" flavor. The inhale is a blast of mixed berries with a tart edge. The vapor is cooler than the Geek Bar, which Jamal preferred for longer sessions. The airflow adjustment on the bottom is a genuine slider, not just a hole. Closing it down tightens the draw significantly, increasing the throat hit warmth. It feels like a device that wants to be a mod but is trapped in a disposable body.

Pros & Cons

Pros	Cons
Huge puff count (25,000)	Very chunky and heavy
Brightness adjustable screen	Sweet flavors gunk up coils near the end
Genuine variable wattage feel	Charging takes longer than XROS
Leather-like grip adds comfort	Disposable battery waste

KEY SPECS & FLAVORS

• Price: $15.99

• Device Type: Smart Disposable

• Smart Tech: HD Screen w/ Animations, Light/Dark Mode

• Puff Count: 25,000

• Battery: 800mAh

• Coil: Advanced Mesh

Ease of Use	5.0	Unbox and go, screen guides you.
Portability	4.0	Definitely a desk or car vape, not pocket.
Overall	4.6	A marathon runner with a smart dashboard.

6. VOOPOO Drag S2: Best Smart Pod Mod

Why We Picked It

The Drag series is legendary, but the S2 introduces the "PnP X" platform. The smart tech here is the Gene.TT 2.0 chip. I tested its "Smart Mode," which physically prevents you from setting the wattage too high for the coil. For Marcus, who often burns coils by accident when switching tanks, this was a coil-saver. It forces you to stay within safe limits.

The vaping experience is dry and crisp. Unlike the wet saturation of Uwell, the PnP X coils offer a very defined, clean flavor profile. I used a 0.3Ω coil with a bakery flavor. The top-airflow design completely eliminates the leaking that plagued previous Drag models. The draw is silent—a "woosh" sound rather than a whistle. The throat hit is substantial but smooth. It bridges the gap perfectly between a small pod and a big box mod.

Pros & Cons

Pros	Cons
Gene.TT 2.0 chip prevents burning coils	Built-in battery eventually degrades
Top airflow eliminates leaking completely	Auto-draw is less sensitive than pods
PnP X coils last incredibly long	Drip tip is not replaceable (proprietary)
Leather grip feels ergonomic	Screen brightness is fixed

KEY SPECS & FLAVORS

• Price: $45.00

• Device Type: Pod Mod

• Smart Tech: Gene.TT 2.0 Chip, Smart/RBA/ECO Modes

• Battery: 2500mAh Internal

• Power: 5W - 60W

• Coils: PnP X Platform

• Airflow: Top Airflow Intake

• Flavors: N/A (Open System)

Battery Life	4.8	2500mAh lasts all day easily.
Leak Resistance	5.0	Best in class due to top airflow structure.
Build Quality	4.8	Zinc alloy + leather is a classic combo.
Ease of Use	4.7	Smart mode makes it beginner friendly.
Portability	4.4	Heavier than a pod, lighter than a mod.
Overall	4.7	Reliable, leak-proof, and intelligent.

7. Lost Vape Centaurus M200: Best Aesthetic Smart Mod

Why We Picked It

This is for the tactile user. The "smart" feature isn't a touchscreen, but a 3-in-1 jog dial control that simplifies the interface. I loved the mechanical feel of turning the wheel to adjust wattage. It also features a physical on/off toggle which boots up the Quest 2.0 chip instantly. It’s "smart" in its efficiency and user interaction design.

Marcus put a Centaurus Sub Ohm tank on this. The ramp-up is aggressive. The Quest 2.0 chip fires hard and fast. The draw depends on your tank, but the power delivery from the mod is consistent and flat—no pulsing or wavering. At 90W, the vape is hot and dense. I found the interface refreshing; instead of clicking buttons 50 times, you just scroll the wheel. It makes dialing in the perfect heat for your specific sweet spot intuitive and fast.

Pros & Cons

Pros	Cons
Jog dial is the best interface in vaping	Boxy shape is not ergonomic for small hands
Stunning engraved aluminum panels	Panels can rattle slightly if loose
Physical on/off switch is convenient	Strictly for advanced users (external batteries)
Quest 2.0 chip is highly efficient	26mm limit for tanks without overhang

KEY SPECS & FLAVORS

• Price: $59.99

• Device Type: Dual Battery Box Mod

• Smart Tech: Quest 2.0 Chip, 3-in-1 Jog Dial

• Battery: Dual 18650

• Power: 5W - 200W

• Material: Aluminum Alloy / Stainless Steel

• Flavors: N/A (Open System)

Battery Life	4.8	Chip manages dual batteries well.
Leak Resistance	N/A	Dependent on tank.
Build Quality	4.5	Beautiful, but panels are magnetic held.
Ease of Use	4.6	Jog dial is easy, but it's an advanced device.
Portability	3.5	Large and heavy.
Overall	4.6	Old-school power with a smart new interface.

8. Off-Stamp SW9000: Best Modular Smart System

Why We Picked It

Jamal was fascinated by this "fidgety" device. It is a smart modular system where the battery dock (800mAh) separates from the disposable pod (200mAh). The "smart" part is the magnetic charging connection. You can vape the small part for stealth, then snap it onto the battery dock to recharge and view the liquid levels. It gamifies the vaping experience.

The draw is incredibly tight and silent—a true Mouth-to-Lung experience. I tested the "Dragon Strawnana" flavor. It’s mellow, not as aggressively icy as the Geek Bar. The vapor is thin but flavorful, mimicking a cigarette volume. The ability to snap the parts together provides a satisfying click. It feels like a gadget. However, I found that if you lose the dock, you are left with a tiny vape that dies in an hour.

Pros & Cons

Pros	Cons
Unique magnetic modular design	Easy to lose the charging dock
Very compact when separated	Total puff count feels less than 9000
Fun to use (fidget factor)	Magnet connection attracts pocket lint
Smooth, tight MTL draw	Charging speed is average

KEY SPECS & FLAVORS

• Price: $14.99 (Kit)

• Device Type: Modular Disposable

• Smart Tech: Magnetic Charging Dock System

• Battery: 200mAh (Pod) + 800mAh (Dock)

• Puff Count: 9000

• Coil: Mesh

• Flavors: Dragon Strawnana, Miami Mint, Juicy Peach, etc.

Review Score

Metric	Score	Remarks
Flavor	4.5	Good, but less intense than Pulse X.
Throat Hit	4.6	Very satisfying tight draw.
Vapor Production	4.0	Discrete, low vapor volume.
Airflow/Draw	4.8	Perfect for stealth vaping.
Battery Life	4.5	Great with dock, poor without.
Leak Resistance	4.8	No leaks experienced.
Build Quality	4.4	Plastic, but magnets are strong.
Ease of Use	4.5	Requires keeping track of two parts.
Portability	5.0	The pod alone is tiny.
Overall	4.5	The smartest design for stealth users.

9. SMOK Spaceman Prism 20K: Best Adjustable Modes

Why We Picked It

SMOK always pushes the envelope. The Prism 20K made the list for its three distinct output modes: Soft, Norm, and Boost. The smart display is massive, covering the front. I tested the "Soft" mode for a morning drive, and it significantly toned down the sweetness and throat hit, making it gentler.

Switching to "Boost" transforms the device. The draw becomes louder and warmer. Marcus liked this for the "Rainbow Belt" flavor, as the heat brought out the candy notes. The smart screen animations are a bit excessive (spaceships flying), but the data is clear. The airflow control at the bottom allows for a very restricted lung hit. It’s a device that lets you tailor the experience more than any other disposable.

Pros & Cons

Pros	Cons
Three distinct power modes work well	Build feels a bit cheap/plasticky
Large, clear information display	Animations are distracting to some
Good airflow adjustability	Device is physically large
"Soft" mode extends battery life	Flavor can be overwhelming in Boost

KEY SPECS & FLAVORS

• Price: $17.99

• Device Type: Smart Disposable

• Smart Tech: 3-Mode Output Control, Large UI

• Puff Count: 20,000

• Battery: 1000mAh

• Coil: Mesh

• Flavors: Rainbow Belt, Apple Kiwi Ice, Blue Razz Ice, etc.

Review Score

Metric	Score	Remarks
Flavor	4.5	Good, but can get harsh in Boost mode.
Throat Hit	4.6	Highly adjustable via modes.
Vapor Production	4.7	High volume in Boost.
Airflow/Draw	4.5	Smooth but slightly noisy.
Battery Life	4.6	1000mAh is a great size for this.
Leak Resistance	4.7	Standard disposable reliability.
Build Quality	4.0	Feels hollow compared to the Raz.
Ease of Use	4.6	Mode button is easy to use.
Portability	4.2	A bit brick-like.
Overall	4.4	Versatility is its main smart feature.

10. OXVA Xlim Pro: Best Compact Smart Device

Why We Picked It

The Xlim Pro is the direct competitor to the XROS 4. Its "smart" claim is the precision wattage control in a tiny stick and the RGB light bar that communicates status. Jamal loved the voice control—wait, no, it's the single button control that locks the fire button but keeps auto-draw active. That specific smart locking feature is a pocket-saver.

The flavor from the V3 pods is top-tier. I vaped a dessert strawberry cream. The Xlim Pro brings out the creamy base notes better than the XROS, which highlights fruit notes. The draw is slightly tighter, a true classic MTL. The screen is small but vibrant. The ability to adjust wattage in 0.5W increments on such a small device gives you control that most pod systems lack.

Pros & Cons

Pros	Cons
Precision wattage control in a stick	Side fill port can be messy
Excellent flavor on dessert profiles	RGB bar might be too flashy for some
1000mAh battery in a slim body	Button is clicky and loud
Smart lock for button firing	Chrome finish attracts fingerprints

KEY SPECS & FLAVORS

• Price: $29.99

• Device Type: Pod Kit

• Smart Tech: Anti-Leak V3 Pods, RGB Interface

• Battery: 1000mAh

• Power: 5W - 30W

Xlim Pro	4.5	4.8	4.7	4.4	4.7	4.6	4.5	4.8	4.6	4.9

The data reveals distinct categories of excellence. The Vaporesso XROS 4 and Caliburn G3 Pro dominate the "Balanced" category. They offer the best compromise between flavor intensity, ease of use, and portability. They are the ideal choice for the average user who wants a "smart" experience without carrying a brick.

For "Specialists," the Geekvape Aegis Legend 3 wins on raw durability and power. Its score is hurt only by portability, which is inherent to the class. If you are a heavy vaper or work outdoors, the "smart lock" and rugged build make it the superior choice despite the size. Conversely, the Geek Bar Pulse X scores high on vapor and ease but loses points on battery sustainability and environmental impact. It suits the weekend social user perfectly.

The Off-Stamp SW9000 is the outlier. It scores lower on vapor production but perfectly on portability and innovation. This makes it a niche pick for fidgeters or stealth vapers. Ultimately, if flavor is your absolute priority, stick to the XROS 4 or Caliburn. If cloud volume matters most, the Legend 3 or Pulse X are your targets.

How to Choose the Best Smart Vape?

Choosing a smart vape requires balancing technical features with your daily habits.

1. Determine Your Preferred Inhalation Style:

If you prefer a tight draw similar to a cigarette, look for devices labeled MTL (Mouth-to-Lung) like the XROS 4 or Off-Stamp. If you want massive clouds and deep inhalation, you need DTL (Direct-to-Lung) devices like the Geekvape Legend 3 or Geek Bar Pulse X.

2. Disposable vs. Refillable:

Disposables (Pulse X, Raz) are convenient and require zero maintenance but are costlier long-term and create waste. Refillable smart pods (XROS 4, Caliburn G3) require buying juice and coils but offer better flavor, lower long-term costs, and reduced environmental impact.

3. Battery Life and "Smart" Drain:

Big screens look cool but drain batteries. If you work long shifts away from chargers, prioritize devices with efficient chips (like the Drag S2 or Legend 3) or large capacities (over 1000mAh) rather than just the biggest animated screen.

4. Purchase Recommendation:

Based on our team's testing:

• For the Everyday User: Buy the Vaporesso XROS 4. It is reliable, tastes amazing, and the smart features actually help maintain the coil.

• For the Convenience Seeker: Buy the Geek Bar Pulse X. It offers the most engaging "smart" disposable experience with consistent flavor output.

Pro Tips for Smart Vapes

• Don't Trust the % Blindly: Liquid indicators on smart disposables are estimates based on puff duration, not actual sensors. When the flavor drops, the juice is done, regardless of what the screen says.

• Lock Your Screen: On devices like the Caliburn G3 Pro or Xlim Pro, always lock the fire button before pocketing to save coil life and battery.

• Clean the Pins: "Smart" detection fails if the connection is dirty. Wipe the gold contact pins on your pod and device weekly with a dry tissue.

• Use the Right Mode: Don't use "Boost" or "Pulse" modes constantly; they degrade coils twice as fast. Save them for when you need a stronger hit.

• Wait After Filling: For refillable smart pods, wait 5 minutes after filling a new pod before vaping. The smart chip cannot save a dry coil from burning if the cotton isn't saturated.

• Charge via Computer: Avoid high-wattage wall chargers for small vape batteries. Using a laptop USB port preserves the battery health of smart pods.

• Reset Puff Counts: Use the puff counter to track coil life. Reset it when you change a coil so you know exactly how many puffs that specific coil lasts.

FAQs

1. What actually makes a vape "smart"?

In our testing, "smart" refers to two things: interface (screens showing juice/battery life) and internal processing (chipsets that auto-adjust wattage, prevent burning, or offer varying output modes).

2. Do smart vapes use more battery?

Yes. Large color screens and animations (like on the Raz or Pulse X) consume power. However, efficient chips (like in the XROS 4) can actually save battery by optimizing power output, offsetting the screen drain.

3. Are smart disposables safer than regular ones?

Not inherently. They use similar internal chemistry. However, the "smart" screens prevent you from vaping a dry device (which produces burnt chemicals) by telling you when the liquid is empty, which is a safety advantage.

4. Can I turn off the screen to save battery?

On advanced mods like the Aegis Legend 3 or Caliburn G3 Pro, usually yes (stealth mode). On disposables like the Geek Bar, the screen is usually automatic and cannot be disabled.

5. Why is my smart vape reading the wrong resistance?

This usually means dirty contacts. Liquid condensation interferes with the smart chip's reading. Clean the base of the pod and the inside of the device.

6. Is the "Turbo" mode on smart vapes worth it?

From Marcus's testing, Turbo modes increase vapor warmth and volume but cut battery life and liquid capacity in half. It is a trade-off between intensity and longevity.

7. Do smart modes really prevent dry hits?

On refillable devices like the Drag S2 or XROS 4, the Smart Mode prevents you from setting the wattage higher than the coil can handle, which definitely reduces dry hits. However, it cannot tell if the pod is empty of liquid.
