The FNIRSI HS-02A is a 100 W digital soldering iron with PID temperature control and USB-C Power Delivery, Quick Charge, or 9–20 V DC power input. It heats up in approximately 5 seconds and adjusts the temperature from 100 to 450 °C, with control accuracy within 2%. It features adaptive power control, saved temperature presets, and automatic sleep mode with a motion sensor.

The housing is made of CNC-machined aluminum and silicone, and the non-slip handle is also made of silicone. ESD protection with grounding capability helps protect sensitive electronic components. The tip is replaceable, and the soldering iron is controlled via a 0.96″ color IPS display and physical buttons.
