Compact USB-C Soldering Iron for Field Repairs

The Mini Soldering Iron is a cordless, rechargeable tool built for residential electronics work, hobby projects and on-the-go repairs. Its 5 W output and adjustable voltage let users tackle everything from delicate PCB joints to thicker wiring without mains power.

Five Voltage Steps Cover Delicate to Lead-Free

Settings at 1.8, 2.4, 3.0, 3.6 and 4.2 volts give fine control over tip temperature. Lower steps suit low-melt solder and sensitive components, while the highest step handles lead-free alloys and heavier gauge wire; beyond 4.2 V the iron cannot go.

Curved Digital Display

The starry-sky screen shows the active voltage in real time, removing guesswork when switching between solder types. A five-click power sequence prevents accidental activation in a tool bag, and the internal battery is dedicated solely to the iron.

Questions about this item

Can the 5 W iron with 1.8 V to 4.2 V settings handle the same delicate PCB joints I do with my bench station?

The five voltage steps from 1.8 V to 4.2 V let you match heat to fine-pitch work or larger pads, so you can replicate the control of a bench unit for small components.

How do I confirm the iron is heating correctly after the five-click start?

The curved digital display shows the active voltage in real time; watch it rise to the chosen level — 1.8, 2.4, 3.0, 3.6 or 4.2 V — and the tip will be ready when the reading stabilises.

Does the package include solder or tips, or must I buy them separately?

Only the iron with its built-in rechargeable battery and a USB-C charging cable are supplied; solder, replacement tips and a heat-safe mat are not included.
