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. At this stage, the priority was not complexity, but reliable power output, safety protection logic, and stable handling of different load conditions, laying the groundwork for future high-level control systems. 2015 | High-Precision Temperature Control Enters Mass Production In 2015, YiHi launched the SX350J, SX350J-V2, and SX450J chipsets. These solutions brought high-precision temperature control into mass-production environments, transforming temperature control from a niche concept into a practical and repeatable solution for everyday devices. During this period, YiHi became one of the key global technology solution providers in the electronic vapor industry. 2016 | Wireless Connectivity and System Interaction In 2016, YiHi joined the Bluetooth SIG and introduced wireless connectivity into vapor device chipsets, releasing: SX480J-BT chipset SX485J-BT chipset SX550J-BT chipset Alongside the hardware, YiHi developed its own application, SXi-Q, enabling device status display and parameter interaction. Later, due to regulatory and platform policy changes, the application was discontinued:the iOS version was removed in 2019,…

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…
