The FNIRSI HS-02 is a portable, screen-equipped soldering iron with up to 100 W of power and a 0.96-inch display. It heats fast, reaches 212–842 °F, and stores three preset temperatures for quick switching. A sleep mode, auto power-off and child lock make it safer to leave on a bench. It suits electronics repair, jewelry work and board-level soldering where a full station is too bulky. Against fixed-station irons it trades thermal mass for portability; against other USB-C smart irons it stands out for its higher wattage and bundled case.
