The FNIRSI HS-02A soldering iron is a 100 W digital model with PID temperature control and a 0.96" color IPS display. The temperature can be adjusted from 100 to 450 °C, while automatic power adjustment controls operation according to the power source. It supports USB-C Power Delivery, Quick Charge and 9–20 V DC power.

Sleep mode automatically lowers the temperature when the soldering iron is placed in its stand and restores it when the iron is lifted. It features ESD protection with grounding capability, a CNC-machined aluminum housing and an anti-slip silicone grip.
