The FNIRSI HS-02B MAX is a digital soldering iron that supports power via USB-C Power Delivery, Quick Charge or DC, with an input voltage of 9–20 V. Its power reaches up to 100 W, while PID control adjusts the temperature from 100 to 450 °C with an accuracy of less than 2%. It features a 0.96" colour IPS display, physical buttons and saved temperature profiles CH1, CH2 and CH3.

Automatic power adjustment adapts to the power source, while sleep mode lowers the temperature when the soldering iron is placed in its stand and restores it when lifted. ESD protection supports grounding. The housing is made of CNC-machined aluminium and silicone, with an anti-slip grip and a replaceable tip.
