Key benefits Simple onebutton operation: press and hold the switch button for 3 seconds to power on. Visible indicators make status clear: temperature gear indicator plus a charging indicator (red = charging, green = charge complete). Stable, selectable heat for different tasks: an upgraded smart chip maintains stable temperature across three adjustable settings so you get consistent solder joints. Portable, flexible power: USB TypeC charging enables charging from a USB port, computer, or mobile power bank — useful for workbench, field, or onthego use. Ready for different jobs: plugandplay design and three included iron heads let you match the tip to the task and the heating core easily. Key specifications and performance Three adjustable temperature gears (upgraded smart chip for stability): Gear 1 (low): 570℉640℃ Gear 2 (medium): 680℉750℉ Gear 3 (): 780℉840℉ Charging and runtime: TypeC charging interface (compatible with USB ports, computers, and mobile power banks) 20 minute energy range 90 minutes to charge complete Accessories: includes three different iron heads for varied soldering needs Design: rechargeable, plugandplay; heating core replacement made more convenient than traditional designs How this product solves problems Replaces bulky corded irons when you need mobility or lack an outlet; charge from common USB sources. Provides stable temperatures across three ranges to match delicate electronics or heavier soldering without frequent tip changes. Includes multiple tips so you can work on fine circuit joints, general wiring, or spot repairs without buying extra accessories. Simple indicators and onebutton operation reduce setup time and minimize user error. Practical applications Electronics and prototyping: solder circuit boards, header pins, and component leads with controlled heat. Small appliance and automotive wiring: reach connectors and wire splices in tight spaces without a cord. Jewelry and hobby projects: perform precise soldering for small metal parts and model building using the smaller included tips. What to expect in use Turn on: press and hold the switch for 3 seconds. The temperature gear indicator shows the selected heat setting. The charging indicator displays red while charging and green when charging is complete. Tip changes: three included iron heads permit quick, tool swaps to match tip shape to the job. Charging: connect to a TypeC power source (USB port, computer, or mobile power). Expect a 20 minute energy operating window and a full charge in about 90 minutes. Compatibility and handling notes Charging: compatible with standard USB TypeC power sources (computer USB ports and mobile power banks). Handling: designed as a rechargeable, portable soldering solution; follow standard safety practices for soldering (ventilation, heat protection, and correct tip handling).
