Twelve South’s latest creation is the PlugBug, a wall charger that piggybacks onto the power adapter included with all MacBooks and enables you to charge an iPhone or an iPad while charging your laptop simultaneously. It costs $34.99.

The PlugBug works with the power adapters included on all MacBook models. It plugs into the AC plug receptacle of your MacBook’s power adapter and then connects to a wall. It sports its own USB plug and provides up to 10W, enabling you to power up an iPad 2 while juicing up your laptop simultaneously.

The PlugBug makes it possible for you to leave your iPad’s separate power adapter behind when you travel, and it also frees up a USB slot on your Mac. What’s more, the PlugBug works independently of the MacBook power adapter – you can just plug it into the wall instead.

The PlugBug gets its unusual red color from author Guy Kawasaki, who was shown an early prototype and suggested the color so the PlugBug could be seen from across the room.
