USB powered soldering iron, this scares us a bit – beyond possibly damaging your computer we can’t imagine it has good thermal properties (but if someone has another point of view, post up in the comments). The most you can get out of a USB port is 5V * 1amp (yes you can get 1 amp before the fuse blows) so thats 5W. We usually suggest 25 W irons to prevent cold solder joints and lifting pads.
