I have an iPod shuffle that I use for running, trains, dull waits, and creep avoidance.
I misplaced the charger a few weeks ago and missed it terribly. The solution? This thing. It plugs into your shuffle on one end, and into a USB port on the other.
I like it better than the original charger because it takes up zero room and since it was $5, I don’t feel bad about just tossing it in my bag. It’s an older USB standard, so it’s slower, fyi. Still. Five bucks. Come on.
