Mini Rechargeable Soldering Iron Pen USB-C 1.5-4.2V 510W Black

Pocket-Sized Soldering Pen

This mini rechargeable soldering iron pen fits in a pocket for true travel convenience. It targets technicians and hobbyists who need a compact tool for on-the-go circuit-board repairs and DIY wiring fixes. The built-in USB-C cable plugs directly into a phone or power bank for immediate power anywhere. A quick heat button enables fast start-up for efficient work sessions.

Adjustable Voltage Range

Adjustable voltage from 1.5v to 4.2v provides controlled, precise heating for delicate components and standard soldering tasks. The LED colour screen displays voltage and battery level in real time so you can monitor headroom during use. The rechargeable internal battery charges via the USB-C port using standard chargers. High-demand or continuous heavy joints may exhaust the internal cell faster than a bench station.

510-Watt Peak Power

The 510-watt rating defines the peak heating capability available for rapid tip temperature rise. This single figure decides whether the pen can melt the solder alloys and joint sizes you encounter in the field. Buyers who need sustained high thermal mass for large connectors or ground planes should note the compact internal battery limits continuous output.
