Mini Portable Solder Pen

The Hazzy Marys Mini Portable Solder Pen is a cordless soldering iron with a 5 W output and adjustable voltage from 2.8 V to 4.0 V. It suits hobbyists, field technicians and electronics students who need a lightweight tool for on-the-go repairs without mains power.

10-Second Heat-Up and USB-C Charging

A built-in 400 mAh battery powers the pen and recharges via USB-C, removing the need for a trailing lead. The tip reaches working temperature in 10 seconds, and the universal threaded connection lets you swap tips quickly when the original wears out.

Check Voltage Range and Tip Thread Before Ordering

Verify that your typical soldering jobs fall within the 2.8 V to 4.0 V adjustment window, as the pen cannot exceed 4.0 V. Confirm that replacement tips you already own use the same universal thread, otherwise you will be limited to the supplied tip.

Questions about this item

How can I confirm the Hazzy Marys solder pen is heating correctly after turning it on?

Watch the LED display; it shows real-time voltage and battery level, and the tip reaches working temperature in 10 seconds.

What comes with the Hazzy Marys Mini Portable Solder Pen and what must I buy separately?

The package includes one solder pen with a built-in 400 mAh battery, a USB-C charging cable, and a removable threaded tip; extra tips or solder are not included.

Which voltage setting should I choose on the 2.8 V to 4.0 V range for my soldering task?

Use lower voltages near 2.8 V for delicate electronics and higher settings up to 4.0 V for heavier joints; the pen offers four selectable levels across that range.
