Top 5 New Features of the XROS 4 Explored

The Vaporesso XROS 4 isn't just a minor update; it's a significant leap forward in pod vaping technology. Vaporesso has packed this device with meaningful upgrades that directly enhance flavour, longevity, and user control. Here’s a breakdown of the key innovations that make this kit a must-have.

COREX 2.0 Technology: A Leap in Flavour and Pod Life

At the heart of the XROS 4 experience is the upgraded COREX 2.0 technology. This isn't just marketing jargon; it's a redesigned system featuring refined mesh and more efficient cotton wicking. The real-world benefit is a more accurate and intense flavour profile from your e-liquids, faster heating, and a pod lifespan that is extended by up to 50%. This update is perfectly showcased in the new 0.4Ω pod, which delivers a powerful and satisfying Restricted-Direct-to-Lung (RDTL) vape with dense, flavourful clouds.

Three Output Modes: Tailor Your Vaping Style

Customisation is central to the vaporesso xros 4. With three distinct output modes, you can perfectly tailor the power to your preference. A quick three clicks of the fire button cycles through the settings, displayed on the screen as:

• Strong: A powerful hit.
• Stronger: An even more intense vape.
• Strongest: The maximum output for bold flavour.

This simple system works in tandem with the airflow control to give you complete command over the warmth and intensity of your vape.

Precise Airflow Control for MTL to RDTL

Vaporesso has equipped the XROS 4 with a highly effective slide-button for precise airflow adjustment. Located on the back of the device, this control allows for seamless transitions between vaping styles. For a tight, cigarette-like draw perfect for Mouth-to-Lung (MTL) vaping with nic salts, simply close the airflow. If you prefer a looser, airier inhale for a Restricted-Direct-to-Lung (RDTL) experience, slide it open. This level of precision ensures the device can adapt to any vaper.

Rapid Charging & 1000mAh Battery

Downtime is kept to an absolute minimum with the XROS 4's impressive power setup. The built-in 1000mAh battery provides reliable, all-day performance for the average user. When it’s time to recharge, the 2A USB-C fast charging capability is a game-changer. You can take the device from empty to fully charged in just 30 minutes, ensuring you’re never without your vape for long.

Performance Review: How Does the XROS 4 Actually Vape?

Technical specifications are important, but the true test of any pod kit is how it performs day-to-day. We put the Vaporesso XROS 4 through its paces to give you an honest, hands-on assessment of its flavour, battery life, and reliability. This is where the device truly shines, moving beyond the numbers to deliver a premium and satisfying vape experience.

Flavour Intensity and Vapour Production

Vaporesso's COREX 2.0 technology is at the heart of the XROS 4's exceptional flavour delivery. The new pods are a significant upgrade:

• The 0.4Ω Pod: This pod is a game-changer for a compact device. It operates best on the highest power setting, delivering a warm, dense, and flavour-rich Restricted-Direct-Lung (RDL) vape. It pairs perfectly with 50/50 freebase e-liquids, producing impressive clouds without sacrificing taste.
• The 0.8Ω Pod: Ideal for Mouth-to-Lung (MTL) vapers, this pod provides a cooler, smoother draw that excels with nic salts. The flavour clarity is outstanding, bringing out the subtle notes in complex e-liquids.

Combined with the precise airflow control, you can easily dial in your perfect draw, from a tight MTL hit to an airy RDL puff.

Battery Life in the Real World

A pod kit is only as good as its battery, and the 1000mAh cell in the XROS 4 does not disappoint. During our testing with moderate use, the battery comfortably lasted a full day. For heavier vapers, the 2A fast charging is a lifesaver, taking the device from empty to full in just 30 minutes. The intuitive LED indicator is simple and effective:

• Green: 100% - 70%
• Blue: 70% - 30%
• Red: 30% - 0%

Pod Longevity and Leak Resistance

Leaky pods are a major frustration for any vaper. Thankfully, Vaporesso's SSS (Seal, Store, Saturate) Leak-Resistant Technology is highly effective. We experienced no leaking or significant condensation during our review period. The COREX 2.0 mesh coils also offer excellent longevity; you can expect a single pod to last between 1-2 weeks before any noticeable drop in flavour. For best results, avoid overfilling the pod and don't leave it in direct sunlight on a hot day.

Vaporesso XROS 4 vs. XROS 3: Should You Upgrade?

The Vaporesso XROS 3 has been a titan in the pod kit market, celebrated for its reliability and flavour. With the arrival of its successor, existing users are asking the crucial question: is it time to upgrade? While both devices deliver a premium experience, the choice depends entirely on your vaping style and what you prioritise in a device. This direct comparison will help you decide if the new vaporesso xros 4 is the right move for you.

Key Differences: XROS 4 vs. XROS 3

For a quick overview, here’s how the two devices stack up against each other. The key upgrades focus on customisation, power, and convenience.

Who Should Upgrade to the XROS 4?

The upgrade is a clear win for vapers who want more control and a more powerful experience. Consider upgrading if you:

• Crave the ability to customise your vape with different power settings.
• Enjoy a strong Restricted Direct-to-Lung (RDTL) hit, which the new 0.4Ω pod delivers perfectly.
• Are a tech enthusiast who values the latest features like COREX 2.0 and rapid 30-minute charging.

Who Can Stick with the XROS 3?

The XROS 3 is still a fantastic, reliable pod kit. There's no urgent need to upgrade if you:

• Are a pure Mouth-to-Lung (MTL) vaper who prefers simplicity over settings.
• Are looking for a great device on a tighter budget, as the XROS 3 offers exceptional value.
• Are perfectly happy with the consistent, fixed output and don't need adjustable power.

Ultimately, the Vaporesso XROS 4 is built for the vaper who wants more versatility and the latest technology. If simplicity is your priority, the XROS 3 remains one of the best choices on the market.

A Simple Guide to Using Your Vaporesso XROS 4

The Vaporesso XROS 4 is designed for simplicity, making it an excellent choice for both new and experienced vapers. Getting started is straightforward, but following these steps will ensure you get the best possible performance and flavour from your very first puff. This guide covers everything from filling the pod to selecting the right e-liquid.

How to Fill and Install the Pod

Vaporesso's top-fill system is clean and efficient. To get your pod ready, follow these simple steps:

• Expose the Port: Securely hold the pod and snap the black mouthpiece off to the side. This will reveal the filling mechanism.
• Fill with E-Liquid: Insert the nozzle of your e-liquid bottle into the red-coloured filling port. Squeeze gently until the pod is full. Be careful to avoid the central airflow hole, as this will cause leaking.
• Prime the Coil: Once filled, snap the mouthpiece back on firmly. If this is your first time using a new pod, it is crucial to let it sit for 5-10 minutes. This allows the cotton wick to become fully saturated with e-liquid, preventing a burnt taste or "dry hit".

Operating the Device: Power and Firing

Operating your device is incredibly intuitive. The single-button interface and clear screen make adjustments simple. Here are the basic controls:

• Power On/Off: Press the fire button five times quickly.
• Vape: The device supports both auto-draw and button activation. You can either inhale directly on the mouthpiece to vape or press and hold the fire button.
• Adjust Power: Press the fire button three times quickly to cycle through the three available power modes. The screen will clearly indicate which level you have selected, allowing you to fine-tune your vapour production.

Choosing the Best E-Liquid for Your Pod

Selecting the right e-liquid is key to a satisfying experience with your vaporesso xros 4. The kit includes two different pods, each suited for a specific style of vaping and e-liquid type.

• For the 0.8Ω Pod (MTL): This pod provides a tighter, cigarette-like draw. It performs best with thinner e-liquids. We recommend using 50/50 VG/PG e-liquids or nicotine salts for a smooth throat hit and excellent flavour.
• For the 0.4Ω Pod (RDTL): This pod offers an airier draw and produces more vapour. It can handle slightly thicker liquids, making it ideal for 50/50 or 60/40 VG/PG blends.

To avoid coil burnout and ensure consistent performance, we advise against using high-VG e-liquids (70% VG or higher) in these pods.

Frequently Asked Questions

How long do the Vaporesso XROS 4 pods last?

A Vaporesso XROS 4 pod typically lasts between one to two weeks. This lifespan depends on your personal vaping frequency, the sweetness of your e-liquid, and the power settings you use. For an average user, a single pod can provide around 10-14 days of consistent, satisfying flavour before a replacement is needed. This longevity makes the XROS 4 a cost-effective and reliable choice for daily vaping, ensuring you get the most out of your premium e-liquids.

Is the Vaporesso XROS 4 good for beginners?

Absolutely. The Vaporesso XROS 4 is an excellent pod kit for beginners. It features simple single-button operation, inhale activation, and easy top-filling pods that minimise mess and fuss. The adjustable airflow and power settings also allow new vapers to easily customise their experience as they learn their preferences. It’s a straightforward, high-performance device that removes the complexity of more advanced kits, offering a premium experience right out of the box.

Can I use old XROS pods with the XROS 4?

Yes, one of the best features of the XROS 4 is its full backward compatibility with the entire XROS pod platform. This means if you have pods from a previous XROS model, such as the 0.6Ω, 1.0Ω, or 1.2Ω versions, they will work perfectly with your new device. This gives you an extensive collection of resistance options to choose from, allowing you to fine-tune your vape for the perfect MTL or RDL experience with your favourite e-liquids.

What do the different coloured lights on the XROS 4 mean?

The LED indicator on the XROS 4 provides a simple way to monitor your battery life. A green light indicates your battery is between 100% and 70% charged. The light will turn blue when the charge level is between 70% and 30%. When the indicator turns red, your battery is below 30% and it is time to recharge the device using the included USB-C cable. This intuitive system ensures you're never caught with a dead battery.

What is the difference between the 0.4Ω and 0.8Ω pods?

The main difference is the vaping style each pod is designed for. The 0.4Ω pod has a lower resistance, creating more vapour and a warmer, airier draw. It is ideal for a Restricted Direct-to-Lung (RDL) vape using freebase e-liquids. In contrast, the 0.8Ω pod provides a tighter, more discreet Mouth-to-Lung (MTL) draw, similar to a traditional cigarette. This pod is perfect for use with nic salts or 50/50 e-liquids and delivers a more defined throat hit.

Does the Vaporesso XROS 4 leak?

The Vaporesso XROS 4 is designed with Vaporesso’s SSS (Seal, Saturate, Store) anti-leaking technology, making it highly resistant to leaks. The top-fill system creates a secure seal to prevent e-liquid from escaping during use or transport. While no vape kit can be guaranteed as 100% leak-proof, proper care such as not overfilling the pod and keeping the connections clean will ensure a consistently mess-free and delightful vaping experience.
