Material and Design This USB soldering iron has a compact size and a comfortable grip for easy portability. The metal housing provides hardness and longterm durability, protecting the internal components and withstanding wear to ensure reliable operation over time. Fast Warming and Integrated Bit The soldering iron uses a plugandplay bit design for fast heat conduction and long lifespan, with antioxidant properties. The bit and heating element are integrated to enable rapid temperature rise, allowing quick heatup and convenient replacement, saving time and effort in the soldering process. ThreeGear Temperature Control Equipped with an upgraded intelligent chip, this iron offers three adjustable temperature settings: Low: 300340C Medium: 380400C : 380450C Longpress the button for three seconds to turn on, with a maximum temperature of 450C. This flexibility supports a variety of soldering tasks. Rechargeable Battery and TypeC Charging An 800 mAh capacity lithium battery provides about 20 minutes of stable operation. The TypeC charging interface enables faster and more convenient charging. It supports multiple power sources, including a computer, USB port, or power bank. A dualcolor charging indicator shows red for charging and green when charging is complete. Practical use scenarios Electronics and PCB work requiring precise temperature control to avoid component damage. Soldering small components, wires, or surfacemmount tasks in portable or onthego settings. Quick field fixes or hobby projects where a compact, USBpowered soldering iron is advantageous.
