The PlugBug Charger from TwelveSouth is a different kind of powered USB charger. Pop the cover off the PlugBug, pop the power prongs off the Mac charger, and then plug them together. US power prongs fold out of the PlugBug. The other end of the PlugBug has a USB port that delivers 5V at 2.1A, so it can charge an iPad, iPhone, or iPod. If you are traveling in the US from another country, you’ll find that the PlugBug also acts as an adapter for US outlets. It’s a convenient way to maximize use of a single power outlet, and it can lighten the load in your gear bag because you won’t need to carry separate power adapters for all your iOS devices. The PlugBug is $34.99 at TwelveSouth.
