Kool Tools: Twelve South's PlugBug
Twelve South's PlugBug (http://www.twelvesouth.com/products/plugbug/) is arguably the most versatile iPad/iPhone wall charger around. The US$34.99 device piggybacks onto a MacBook power adapter, so you can charge an Apple laptop and an iOS device simultaneously from one power outlet.
The charger -- which packs 10 watts (twice that of a typical USB charger) -- connects to all MacBook, MacBook Pro and MacBook Air power adapters. Simply snap the PlugBug onto an adapter in place of the adapter’s AC plug. This means less chargers in your computer bag and reduced clutter.
If you only need to charge your iPad or iPhone, PlugBug works as a stand-alone wall charger. Slide it off your MacBook power supply and slip on the included cap to use PlugBug as an extra iPad charger.
Those outside the U.S. and Canada will find another use for the Twelve South device. They can use the PlugBug as a U.S. adapter and iPad/iPhone charger. Not only does PlugBug convert any non-U.S. MacBook power adapter into a North American-compatible adapter, it also serves as a bonus USB charger for iPad and iPhone.
