The FNIRSI HS-02 Smart Soldering Iron is a portable, digitally-controlled tool built for electronics hobbyists and technicians who need both precision and portability. Unlike traditional bulky irons or low-cost models that risk overheating components, this smart soldering iron delivers controlled performance in a lightweight design. 
It heats up to working temperature within seconds and features an OLED display, USB-C power input, and intelligent temperature regulation. These capabilities make it a dependable solution for accurate soldering in electronics assembly and repair, providing a safer, more efficient experience whether you’re working in the lab or out in the field.


Ordering


The Fnirsi smart soldering iron can be purchased through their official website or via AliExpress; both links are provided in the description below. When ordering, you have the option to select a kit that best suits your needs, ranging from a simple carry case to a portable toolbox, with the choice to include a US or EU power adapter.
For this review, I went with the carry case option without the power adapter.

Unboxing 


Let's see what showed up in the mail today! The soldering iron came in excellent, high-quality packaging with instructions in both English and Chinese. 
The product is offered in two variants, the HS-02A and HS-02B, differentiated by the included soldering tips. I selected the multipurpose HS-02A Intelligent Electric Soldering Iron.

The product's key specifications, as listed on the box, are as follows:

  • Voltage: is between 9-20V
  • Temperature Range: is between 100-450°C / 180-842°F
  • Display: It has 0.96" IPS HD color OLED display for monitoring and adjusting temperature
  • Connection & Charging: It features a Type-C port compatible with PD and QC fast charging protocols
  • Power & Performance: It delivers up to 100W of power for rapid heating

Alright, let's open it up!
Inside the box, there is a compact, stylish black case with a blue zipper. Let's unzip the case and see what's inside.

Unzipping the case reveals a well-organized kit. The contents include:

  • A quick-start user manual 
  • A USB Type-C cable
  • A soldering tip
  • A base station
  • And the smart soldering iron itself

Getting started is straightforward. You begin by twisting the cap to open it up and pop your soldering tip inside. An additional soldering tip for 3D Printer Heat Insert Nut is also included in the package.


To bring it to life, all you have to do is plug in the USB Type-C cable "and" we're in business!

 

Features & Specs


The FNIRSI HS-02 Soldering Iron features an upgraded ergonomic design with a comfortable grip, a shorter tip for better control and reduced fatigue, and a large 0.96" display.
Plugging the USB-C cable boots the unit up. Press the "OK" button to start the heating process. With a powerful 100W output, it heats up rapidly and melts tin in seconds, making it ideal for a wide range of tasks from electronic component repair to delicate micro-soldering.

Press the "OK" button to put the unit in standby mode. Use the up and down arrows to adjust the temperature, the amount it changes is determined by the preset "step size" saved in the memory.

Just hold down the up and down buttons together to get to the main menu. Let's take a quick tour of what's in here.
The first option is "Sleep Set". Press the "OK" button to enter this sub-menu and over here you can configure, the:

  • Sleep Time
  • Standby Time &
  • Sleep Temperature

Now, long press the "OK" button to go back to the main menu. The second option is the "Handle Set". Over here you can set the:

  • 3 groups of Pre-Set Temperatures
  • Voltage
  • Power
  • Steps at which the temperature rises or falls when the arrow buttons are pressed, and the
  • TEMP Calibration option

If you're not familiar with these settings, it's perfectly fine to just stick to the defaults.

The third option is the "System Set". Over here you can configure the:

  • Language
  • Left or Right hand mode
  • °C or °F display
  • Volume 
  • Brightness
  • Roll Set
  • You can even update the firmware
  • And check the current version from the About menu

To return to normal mode, simply hold down both arrow buttons. The soldering iron will then immediately resume heating. The soldering iron features intuitive power management. It automatically enters sleep mode when placed in its stand and instantly resumes heating when picked up. If you just need a quick break, a short press on the "OK" button will put it to standby.


Quick Demo & Warranty


Let's put it to the test and see how it performs in a real-world scenario. Watch this, the solder melts instantly on contact. Honestly, this is the best portable, budget-friendly smart soldering iron I've ever used. It's an absolute game-changer.

The heat-resistant cover allows you to pack it up safely even when the tip is hot, making it truly portable. Plus, it can also run from either a car outlet or a power bank.


And for peace of mind, it comes with a 30-day return and refund guarantee. If you buy it directly from FNIRSI.com, you'll also get a full 2-year warranty and lifetime technical support directly from them.

So, who is this for?
