Overview
Soldering small joints on circuit boards and jewelry is the work for this FNIRSI pencil-style iron. It has a ceramic heating element, a silicone handle and preset heat settings, and the kit adds tips and a storage bag.
Presets and auto sleep make it simple to use for electronics repair. The listing calls it wireless but also gives the power source as corded, and it does not say which tips are included.
Who it's for
Electronics repair, hobby builds and jewelry soldering. Heavy joints on large components need a higher-wattage iron.
Pros and cons
- Preset temperature levels
- Auto sleep function
- Ceramic heating element
- Storage bag included
- Power source entry conflicts
- Tip shapes not itemized
- Low wattage limits big joints
Performance notes
A ceramic element heats quickly and holds a set temperature, and preset levels let you match solder and work. Wattage limits how well it recovers heat on big joints. Auto sleep cools the tip when idle.
