Full Product Description

100W High-Power Heating in 2 Seconds

The FNIRSI HS-02A redefines portable soldering with its impressive 100W maximum power output. When connected to a compatible PD or QC fast charger (9-20V), the iron heats up and melts tin in as little as 2 seconds. This rapid thermal recovery ensures that the tip temperature remains stable even when soldering large ground planes or thick wires, making it an essential tool for drone builders, RC hobbyists, and PCB repair technicians.

Smart Temperature Control with 0.96" IPS Display

Equipped with a segmented PID temperature control system, the HS-02A maintains an accuracy of <2% across its 100°C to 450°C range. The vibrant 0.96-inch HD color screen provides real-time feedback on current temperature, set temperature, and power input. You can easily save and switch between three preset temperature groups, allowing you to transition from delicate SMD micro-soldering to heavy-duty wire tinning without wasting time adjusting settings.

Ergonomic CNC Metal Design for Precision Work

Designed in accordance with human mechanics, the 180mm length and silicone anti-slip grip make the HS-02A incredibly comfortable for extended soldering sessions. The premium CNC metal shell not only looks professional but also dissipates internal heat effectively. The included anti-scalding pen cap allows you to pack the iron away safely immediately after use, protecting both the tip and your storage case.

Technician Tip

To achieve the full 100W performance, you must use a high-quality Type-C cable and a power adapter that supports 20V/5A PD output. Standard phone chargers will work, but the iron will automatically adapt to a lower power output, resulting in slower heating times. The package includes the versatile HS-02A-K (Knife) tip, which is excellent for drag soldering and general component repair. If you need a high-power PD charger or additional tip shapes, visit our physical store at Sun Cheong Computer Co. Ltd. in Sham Shui Po.

FAQ Section

Does the package include a power adapter and Type-C cable?

No, the standard package includes the HS-02A main unit, the K-type soldering tip, and a storage case. You will need to provide your own Type-C cable and a PD/QC compatible power adapter or power bank.

How do I get the full 100W power output?

To achieve the maximum 100W output, you must connect the soldering iron to a power adapter that supports the 20V/5A Power Delivery (PD) profile, using a Type-C cable rated for 100W.

What is the difference between the HS-02A and older models?

The HS-02A features a fully upgraded design with a shorter tip-to-grip distance for better precision, a larger 0.96" color display, a premium CNC metal shell, and an included anti-scalding cap for safe storage immediately after use.

Can I use this for micro-soldering on mobile phone motherboards?

Yes, the precise PID temperature control and the ergonomic grip make it highly suitable for micro-soldering. While the included K-tip is versatile, you may want to purchase a finer conical tip separately for extremely delicate SMD work.

Is the FNIRSI HS-02A available for immediate pickup in Hong Kong?

Yes, we stock the FNIRSI HS-02A smart soldering iron kit at our Sham Shui Po physical store. You can order online for delivery or visit us during business hours for instant pickup.
