A cordless tool for close work.

The pen format gives you a direct grip near the task without a power cord trailing from the handle during use. Its 10W output suits fine soldering jobs and small electronics. Choose a suitable tip, prepare the joint, and work with the control the task requires.

Temperature display and adjustment controls

Set the heat for the job.

The display lets you see the selected temperature across a 100–450°C range, or approximately 212–842°F. Interchangeable F210 tips give you options for reaching different small connections. The useful part is having the setting and the tip choice close at hand.

HS-03 pen, three tips, USB cable and case

Pack the session away neatly.

A rechargeable 2600mAh 18650 battery supplies the pen, with USB-C charging and sleep functionality built into the tool. The supplied case keeps the pen and tips together between sessions. It is a practical companion for a compact repair bench or an electronics hobby kit.

In the box

FNIRSI HS-03 cordless soldering pen, removable 2600mAh battery, three F210 tips, and storage case. Solder, flux, workholding equipment, and protective equipment are separate.

A few useful answers

Is it suitable for large joints or heavy wiring?

The 10W pen is intended for fine work. Large thermal masses, heavy cables, and substantial metalwork may need a more powerful soldering station.

How do I charge it?

Use the USB-C charging connection and follow the supplied battery and charging instructions. Allow the tip to cool before storage or tip changes.

What else do I need?

Use appropriate solder and flux, a stable heat-resistant work surface, ventilation, and suitable eye protection. This is a hot tool for users familiar with safe soldering practice.

    On the seller's part, everything was perfect, but as for the delivery, it was not delivered to the detailed address, which led to misunderstandings as the package did not appear at the pickup point. In the end, the product is now in my possession and appears to be in perfect condition; I have not tried it yet.
