You can run a SNES or sfc off any 5v usb 1a charger with just a couple of simple mods. The SNES/sfc maxes out at 5v 1.5a internally (has a 1.5a super fast acting fuse). It uses a 7805 voltage regulator. If you remove the regulator and jump the in and out points you can feed the input source 5v and the system will work. The SNES/sfc uses the 10v to power the sound amp but it will work off 5v as well. You can then desolder and remove the power jack and replace it with a USB port.(will have to carefully cut it out since it's molded into the plastic av plate) if interested I can post pictures of my SNES that ive modded for component video, digital sound and USB power. I can also take a video of it being powered by a selection of usb chargers and batteries.
