This is all very simple and very strange. With a spare USB port on your computer you can power/recharge damn near anything, granted you have the appropriate cable. Electronics-vendor Brando seems to be hunting down every single USB-powered device it can find, including this electric razor.
Pretty straightforward: Plug the razor into a USB port, charge it up and shave stuff. I’d go through the specs, but really, if you’ve reached the point of having to go to your computer to get a good shave, you’ve got bigger problems. This is definitely a nice gift though, for that unkempt person on your list that might need an emergency shave before a meeting or at the end of the day before a business dinner. And it’s just $22.
