Product details
Bring a compact soldering tool to your next small electronics repair. The FNIRSI HS-03 cordless soldering iron kit includes three F210 tips and a case, with 10W output and an adjustable 100–450°C range. A removable 2600mAh battery and USB-C charging keep the essentials together between projects.
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.

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.

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.

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.
