FNIRSI HS-02B Plus Tool Box 100W USB-C PD Soldering Iron with 0.87 inch OLED Display, 80-420°C, 6s Heat-Up, Aluminum Alloy Body, Adjustable Sleep/Shutdown, Firmware Upgradeable

The FNIRSI HS-02B Plus Tool Box redefines portable soldering with a 100W power ceiling and USB-C PD input, eliminating bulky base stations while delivering desktop-grade thermal performance. Unlike traditional corded irons, this model heats to 300°C in approximately 6 seconds and maintains ±2°C stability across an 80–420°C range, making it ideal for fine-pitch electronics, drone repair, and field service. The aluminum alloy housing ensures durability without weight, and the 0.87-inch OLED screen provides crisp real-time feedback. Three tactile buttons let you adjust temperature, switch between Celsius and Fahrenheit, calibrate the tip, and configure sleep/shutdown timers—all without a smartphone. The Plus Tool Box variant includes a protective carrying case and accessory storage, keeping the iron, tips, and cable organized for mobile work.

In daily use

Connect the HS-02B to any USB-C PD power adapter rated 65W or 100W (not included) and you are ready to solder in seconds. The ergonomic grip stays cool during extended sessions, while the OLED screen remains readable in bright environments. For bench work, pair it with a 100W PD charger to unlock full performance; for field repairs, a 65W power bank still delivers ample heat for most tasks. The adjustable auto-sleep function conserves energy and extends tip life, and the auto-shutdown prevents accidental burns. The included tool box organizes the iron, a selection of tips, and the USB-C cable, making it a complete portable soldering kit.
