Precision Portable Soldering Pen

This cordless digital soldering iron delivers adjustable heat from 1.8 V to 4.2 V at 5 watts for PCB, circuitry and electronics repair. Its 15.7 cm smart-pen form factor balances industrial-grade precision with true field portability. The 510-threaded tip interface allows rapid swaps to match each joint. A five-click safety lock prevents accidental activation during transport.

Voltage Range and Power Headroom

The 1.8 V to 4.2 V span covers fine SMD rework through modest through-hole joints on a single charge. At 5 watts the iron maintains steady temperature on small pads and thin wires but reaches its limit on large ground planes or heavy connectors. USB-C charging restores full operation quickly so downtime stays minimal between sessions.

Upgrade From Butane or Tethered Irons

Technicians moving up from butane pencils gain repeatable voltage control and eliminate fuel refills. Bench users cutting the cord keep precise digital regulation while gaining unrestricted reach. The jump is worth it when consistent tip temperature and tip-change speed matter more than raw thermal mass for extended heavy joints.

Questions about this item

Will the 510-threaded tips I already own fit this 15.7 cm iron?

Yes, the 510-threaded interface accepts standard 510 tips so your existing tips will screw in securely.

How do I confirm the iron is heating correctly after I charge it via USB-C?

Press the button five times to unlock, set the voltage between 1.8 and 4.2 V, and the tip will reach the selected temperature for soldering.

Does the package include soldering tips or only the iron body?

The iron body is included; 510-threaded tips are sold separately.
