The Fnirsi HS-03 is a cordless soldering iron suitable for all on-the-go electronics repairs and SMD work, with a 100°C to 450°C temperature range and the same precision tips as the Fnirsi HS-02B. The 2600mAh battery is replaceable, and a USB-C port allows for soldering on socket power once the battery runs out. Five temperature presets allow quick switching between frequently used settings. No power adapter is included, but we offer a 65W adapter, and a heat-resistant USB-C cable for soldering on socket power. Eleshop has tested the iron's battery for safety before listing it, since battery safety on budget cordless tools is not something to take for granted.
Furthermore, the soldering iron only draws 10W, so it is most suitable for fine electronics work. Heavy joints, thick wires and ground planes are better handled by a higher-power model such as the Fnirsi HS-02B. No stand is included. The HS-02A and HS-02B toolbox kits include a case that doubles as a stand.
