How many times have you wanted to charge your iPod or iPhone from your computer or some else's, without the hassle of synchronizing to iTunes, or worse, worrying about accidentally erasing all your music?

Introducing the Tune Blocker™. With the flip of a switch, Tune Blocker allows you to choose whether you want to simply charge your iPod or iPhone, or sync it to your iTunes library as well.

USB connectors are flat. iPod connectors are flat. If you try plugging one in upside down, it won't go in. You need to flip it over and try again. Very annoying.

The Tune Blocker's USB and iPod plugs have raised lettering so you can feel which way is up. You'll get it right every time.
