It seems everything is available these days powered by USB — the little rectangular connection ports on your PC. Not only a communications channel to your printer and other peripherals, the USB port can provide power — thus we have USB powered hard drives, USB-powered fans, and, now, USB-powered … pregnancy tests.
No info on whether you can speed up the pregnancy if the port is USB 2.0 compliant.
I first saw this one on Tuesday (hint). You might want to take another look at the article.
Firk-ding-blast! Got me.
