Portable USB Soldering Pen

This cordless iron reaches working temperature in ten seconds and offers three preset levels at one hundred, two hundred and three hundred fifty degrees Celsius. A built-in nine hundred milliampere-hour cell delivers up to twenty minutes of continuous high-temperature use before needing a recharge. The kit includes three interchangeable tips and charges via a Type-C port in sixty minutes.

Thermal Behaviour and Power

The integrated heating core provides precise and stable temperature control across all three gears while drawing power only from the internal battery. An automatic sleep function activates after ten minutes of inactivity to conserve charge and reduce tip wear. No mains cable or external power supply is required during operation.

Battery Runtime Constraint

The twenty-minute high-temperature limit means the tool suits quick repairs, hobby soldering and light field work rather than extended bench sessions. Users who need uninterrupted welding for longer periods should consider a mains-powered station instead.

Questions about this item

How do I charge the iron and what indicates it is ready?

Connect the TYPE-C port to any 5 V source — power bank, wall plug or computer — for 60 minutes; the red light stays on while charging and turns green when the 900 mAh cell is full.

When will I need to replace the tip or heating core?

The integrated tip and core unscrew together; swap them when the 18 second tinning time lengthens or the three preset temperatures (100 °C, 200 °C, 350 °C) no longer hold steady.

How long can I run continuous high-temperature joints before the iron stops?

At the 350 °C red setting the iron delivers 20 minutes of work; after 10 minutes of inactivity it enters automatic sleep to preserve the battery.
