Razor charges from your computer
A company called ShaveTech has an interesting electric shaver that might be appealing to geeks are always on the go. Rather than needing electric outlet or believes that you have to replace, this razor recharges from USB port on your computer. Granted, you need to have a computer nearby with the USB port.
One upside to using a USB port to charge the shaver is if you travel internationally, you don't need an adapter to plug in. The razor sells for $39.99 online and in select retailers in the US and Canada. The integrated USB connector hides away when the battery doesn't need to be charged. I wonder how good this thing actually works.
