In recent years, the majority of soldering iron manufacturers have switched to using cartridge-style tips, which integrate the heater and thermocouple for optimal thermal conductivity and fast response. As a result, most soldering irons and stations that use these tips offer adequate soldering performance for the average user.
While reviewing thermal performance in great detail may not be as crucial nowadays, aspects like usability and accuracy are more important to consider. The FNIRSI HS-01 soldering iron is a portable and capable option that impresses with its excellent build quality and functionality. It comes with a 65W GaN USB-C charger, a flexible silicone-insulated USB-C cable, and a compact holder for the iron.
The tips are similar to Hakko T12 or T15 but shorter, allowing for greater precision when soldering small components. One standout feature is the intuitive temperature adjustment in 10-degree increments, making it quick and easy to dial in the desired setting. The iron also offers a sleek OLED display, a power percentage bar graph, and various settings accessible through a menu system.
In testing, the FNIRSI HS-01 handled soldering tasks with ease, from melting solder on large pads to precisely soldering pin headers and SMD components. Its ability to run from a power bank adds to its portability, making it an excellent choice for on-the-go soldering or as a backup to a dedicated soldering station.
Overall, the FNIRSI HS-01 soldering iron is a highly recommended option for those seeking a portable and capable soldering solution, offering excellent value for its performance and features.
