Key Benefits Safe: builtin autooff powers the iron down after 10 minutes of continuous use to reduce burn and fire risk. Cordless convenience: integrated 800 mAh battery and USB charging eliminate the need for a constant power cable, making handheld work easier and more mobile. Precise control: three temperature settings let you match heat to the task, reducing damage to sensitive components. Comfortable and secure handling: heatinsulated surfaces and a nonslip handle protect your hands and improve control during delicate work. Main Features and Performance Power and charging: builtin 800 mAh battery; charges via USB for flexible recharging from power banks, laptops, or USB adapters. Temperature settings: Level 1 (indicator light 1): approximately 300–340 °C Level 2 (indicator light 2): approximately 360–400 °C Level 3 (indicator light 3): approximately 420–450 °C Controls: press and hold for 5 seconds to switch the soldering iron on or off. Use a short press to cycle between the three temperature modes. Safety and ergonomics: heatinsulating surface reduces the risk of burns; the handle is designed to be comfortable and nonslip for extended or precision tasks. Wide application range: suitable for soldering circuit boards, small electronics and components, household appliance repairs, wiring and device maintenance, jewellery and watch , guitar electronics and similar tasks. Practical Use Scenarios Electronics : remove and components on PCBs, solder wires and connectors on computer hardware or small gadgets using the appropriate temperature setting to protect sensitive parts. Home appliance and wiring fixes: perform quick wiring repairs, connector replacements, and capacitor work without needing a workspacetethered iron. Hobby and instrument work: solder pickups, switches, or wiring on guitars; perform detailed soldering on watches, jewellery, and other small items where controlled heat and a steady grip are essential. What you should expect Portable, USBrechargeable soldering iron with three temperature levels, intuitive on/off and temperature controls, heatinsulated housing, and an automatic 10minute shutoff for safer operation.
