Portable Soldering Iron

This cordless soldering iron integrates a 1100mAh battery for cable-free operation. It targets hobbyists and technicians who need a lightweight tool for circuit board work, appliance repair or jewellery welding away from a mains socket. The 15W output and replaceable 510 tip cover a range of light-duty joints.

45-Minute Runtime and Four Voltage Steps

A full charge delivers 45 minutes of continuous use before the battery needs recharging. Four voltage settings — 3.3V, 3.8V, 4.3V and 4.8V — produce tip temperatures from 392 to 878, equivalent to 200 to 470. The graduated knob locks to prevent accidental shifts during a joint.

Hold-Button Safety Interlock

Heating activates only while the power button is held down; releasing it cuts power instantly. The manual requires the button to be released every 8 to 12 seconds to protect the tip from overheating. This interlock makes the iron unsuitable for users who prefer a latched, hands-free heating mode.

Questions about this item

Will the 510 tip on this iron fit the older Weller tips I already own?

The iron uses a replaceable 510 tip design; it accepts 510-style tips only and is not compatible with Weller or other proprietary tip series.

How can I confirm the 15 W iron is heating to the chosen 3.3 V, 3.8 V, 4.3 V or 4.8 V setting after I set the knob?

The bottom knob has clear graduations and a locking detent for each voltage; when you press and hold the power button the tip reaches temperature in 8 to 12 seconds, indicating the selected mode is active.

Does the box include a 5 V 2 A charger or do I need to supply my own USB-C power adapter?

The supplied kit contains the soldering iron with built-in 1100 mAh battery and 510 tip; a 5 V 2 A charger is not included and must be purchased separately.
