FNIRSI HS-02B is a smart 100 W digital soldering iron with fast heating in about 2 s, precise PID temperature control, and universal power input (USB-C PD, Quick Charge, and DC). Thanks to the 0.96" IPS display, adaptive power management, automatic sleep mode, and ESD protection, it is ideal for electronics repair, SMD/BGA work, and portable field use.
FNIRSI HS-02B combines high power and mobility in a compact body. The maximum 100 W ensures fast heat-up and, most importantly, stable temperature under load—useful when soldering thicker wires, connectors, shielding, and larger soldering pads. The clear color IPS display and physical buttons allow quick setup without delays.
A major advantage is the universal power supply: the iron can be powered from a compatible USB-C charger (PD), a power bank, a laptop, or from a bench power supply via the DC input in the range 9–20 V. Adaptive power regulation automatically adjusts the draw to the capabilities of the power source, helping protect the supply and the tip while maintaining stable performance.
For safe work with sensitive electronics, it provides ESD protection with grounding capability and precise segmented PID control in the range 100–450 °C. Also practical are the temperature profiles CH1/CH2/CH3 and automatic inductive sleep, which lowers the temperature when placed down and restores it immediately when picked up.
