Fnirsi HS-02A 100W Soldering Iron

Fnirsi HS-02A is a compact soldering iron powered via USB-C with output up to 100 W, supplied in a carrying case with one tip. It is suitable for building and servicing FPV drones in the workshop as well as field repairs. It is powered from an adapter or power bank supporting fast charging PD/QC at 9–20 V, so it works anywhere a more powerful USB-C source is available.

The temperature is adjustable in the range 100–450 °C with three switchable presets (factory set to 300, 330 and 360 °C). The color 0.96" IPS display shows the set and actual temperature, input voltage and heating power indicator; it is controlled by three buttons, and the display can be rotated in the menu for right- and left-handed users. The soldering iron supports sleep mode with reduced temperature (100–200 °C after 1–60 minutes of inactivity), standby mode with automatic shutdown, child lock and buzzer. For weaker sources, it has adaptive power mode and manual selection of 9/12/15/20 V with power limiting in the 10–100% range, so it does not overload the power bank.

The iron uses HS02A series tips. The package includes one HS02A-B tip. The silicone-grip body weighs only 61 g, has a socket for ESD grounding at the rear end, and a protective cap is fitted to the tip for transport. Firmware is updated via USB-C — the iron appears on the computer as a drive, and the new firmware is simply copied to it.

The tips of the HS-02A and HS-02B versions are not interchangeable

The USB-C power adapter is not included.
