When people search for better vape performance, they often ask: • Why does my vape feel weaker when battery is low?• Why is flavor not consistent from full charge to empty?• What is voltage control in vaping? These problems are directly related to voltage regulation inside the device. Many users focus on wattage numbers or battery size.But in reality, stable voltage output is the key to consistent flavor. This is where SXmini devices powered by YiHi chips make a real difference. 1. Battery Voltage and Puff Performance In any vape device, battery voltage naturally drops during use: • Full battery: around 4.2V• Mid battery: around 3.7V• Low battery: around 3.3V Without proper voltage control: • Full battery → stronger hits• Lower battery → weaker vapor and flavor This is why many users feel their vape performance changes over time. SXmini devices use advanced YiHi chip technology to keep output stable, even when battery voltage drops. 2. What Is DC-DC Voltage Regulation? DC-DC voltage regulation is the core of modern vape power management systems. It converts battery voltage into a stable output voltage. There are three main types: • Buck (Step-Down)• Lowers voltage when battery is too high • Boost (Step-Up)• Increases voltage when battery is too low • Buck-Boost (Full Range Regulation)• Adjusts voltage both up and down 👉 This is the most important technology for consistent vape performance. Most SXmini devices use true Buck-Boost regulation, allowing stable output across the entire battery range. 3. PWM Vaping Explained (Why It Feels Different) PWM (Pulse Width Modulation) is commonly used in…

Power Mode · Temperature Control · PURE Mode In the vaping industry, different devices may operate using different modes.These modes are designed for different user habits and experience levels, not to replace one another.

At SXmini, we believe a strong brand is not built only on success, but also on how it responds to challenges. Over the years, SXmini has worked with partners, distributors, retailers, and users across many countries and markets. From the beginning, our goal has always been clear: to create reliable, well-designed vaping products powered by advanced YiHi chipset technology, while listening closely to real user feedback. Like any brand focused on long-term growth, we have also faced moments that tested us. Learning from Early Product Challenges In the early stage of the PX Cartridge (Black version), we did not fully consider the wide differences in e-liquid formulas used in different countries. As an open pod system, its compatibility with certain e-liquids was not ideal in some markets. Instead of ignoring these issues, we collected feedback from partners and users worldwide. Our engineering team made continuous improvements, adjusted internal structures, and tested multiple revisions. These efforts finally led to the release of the PX Pro 2 Cartridge, offering much better stability and broader e-liquid compatibility. This process reminded us that real product improvement always starts with listening. Taking Responsibility and Improving Quality Control We also openly acknowledge an issue that occurred with the first batch of Puremax 2, where a battery defect from an upstream supplier caused charging problems in part of the shipment. Once the issue was identified, the battery problem was fully resolved in later production batches, and replacement units were arranged for our partners. More importantly, this experience helped us strengthen supplier screening, battery testing, and quality control…

YiHi Chipset Technology Evolution From E-Vapor Control to Multi-Industry Intelligent Control Solutions In the world of electronic vaporization, the true foundation of user experience has never been appearance or specifications alone, but the depth of control behind the system. YiHi's chipset journey began with a simple question:how to drive vaporization safely, stably, and consistently under real-world conditions. Over more than a decade of continuous development, this focus gradually shaped a control philosophy that now extends beyond e-vapor devices into multiple intelligent control applications. 2014 | The Beginning of Vapor Control In 2014, YiHi introduced the SX300 series chipset, marking its formal entry into electronic vapor control.

Temperature control is one of the most searched topics in advanced vaping. Many users ask: • What is temperature control vape?• Why do I still get dry hits with TC?• DNA TC vs YiHi TC, what is the difference?• Which temperature control is better? This guide explains the difference between Evolv DNA temperature control and SXmini Dynamic Heating Curve. 1️⃣ What Is Evolv DNA Temperature Control? Evolv DNA chipsets use what is commonly called Temperature Protection (TC mode). How it works: • Measures coil temperature based on resistance change• Uses temperature control wire (Ni, Ti, SS)• Reduces power when the set temperature is reached• Prevents the coil from going above the temperature limit 👉 In simple terms: • You set a temperature (for example 220°C)• The device will not allow the coil to go above that temperature This helps: • Prevent dry hits• Reduce burnt taste• Keep temperature stable 👉 This is often called: CONSTANT Temperature Control Because the temperature is limited by a fixed ceiling. 2️⃣ What Is SXmini Dynamic Heating Curve? SXmini uses a different approach called Dynamic Heating Curve. Instead of fixing temperature at one limit, the system: • Adjusts power in real time• Works within a safe temperature range• Responds to how you vape During each puff, the system reacts to: • Inhale strength• Puff duration• E-liquid supply• Coil condition How it behaves: • Start of puff → slightly higher power to boost flavor• During puff → adjusts output to keep flavor smooth• Low e-liquid → reduces power to avoid dry hit 👉 In simple terms:…

SXmini temperature control does not rely on fixed power output or a single heating point.Instead, it introduces a Dynamic Heating Curve design. This curve is not a straight line.It continuously adjusts within a safe temperature range, allowing the device to respond to real vaping conditions in real time. How does the Dynamic Heating Curve work? During each puff, the system evaluates multiple factors, including: Inhalation strength Heating duration E-liquid supply condition Changes in the heating element during operation Based on this information, the output is adjusted instantly and precisely: Initial draw:Heating response is slightly increased to release flavor faster Stable inhalation:Output is dynamically adjusted to keep the vape full and smooth Low e-liquid or supply changes:Heating strength is automatically reduced to prevent overheating and dry hits This process forms a continuously fluctuating but well-controlled heating curve. Why does “controlled fluctuation” improve stability? Most traditional vape devices use: Fixed wattage Or a fixed temperature point When e-liquid conditions change, these systems often lead to: Normal flavor in the first few puffs Overheating in later puffs Or sudden burnt taste SXmini’s Dynamic Heating Curve allows temperature to rise and fall slightly within a controlled range,making it better suited to real-world usage conditions. As a result: More consistent flavor delivery Fuller and more complete taste expression Stable performance from the first puff to the last Benefits in open-system pod devices In open pod systems, the Dynamic Heating Curve provides clear advantages: Faster flavor activation Better heat control during continuous vaping Reduced risk of burnt taste when e-liquid runs low Smoother and more durable…
