Fnirsi HS-02A 100W Soldering Iron + Tip Set

Fnirsi HS-02A is a compact soldering iron powered via USB-C with up to 100W output, supplied in a carrying case with a set of six soldering tips, a tip cleaner, solder, and a stand. 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 with PD/QC fast-charging support at 9-20V, so it works anywhere a more powerful USB-C source is available.

Temperature is adjustable in the range of 100-450°C with three switchable presets (factory default 300, 330, and 360°C). The color 0.96" IPS display shows both the set and current temperature, supply 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 features sleep mode with reduced temperature (100-200°C after 1-60 minutes of inactivity), standby mode with automatic shutoff, child lock, and a buzzer. For weaker sources, it has an adaptive power mode and manual voltage selection of 9/12/15/20V with power limiting in the 10-100% range, which prevents overloading the power bank.

The iron uses HS02A series tips — six are included in the package (B, C2, I, JS, K, KU), from fine tips for SMD work to wider ones for XT60 connectors and power pads. The body with a silicone grip weighs only 61g, has a socket for antistatic grounding at the rear end, and a protective cap fits over the tip for transport. Firmware is updated via USB-C — the iron appears on a computer as a drive, and the new firmware is simply copied to it.

HS-02A and HS-02B tips are not interchangeable.

The USB-C power adapter is not included.
