The PlugBug from Twelve South is a brilliant idea, if I may be so bold. It’s a 10w USB charger that piggybacks onto a standard MacBook power adaptor to create one neat unit.
Choosing contrasting red, rather than trying to match Apple’s white, is a masterstroke.
I’m smitten, even though it is only for use in the USA. For the asking price of $34.99 this is something I will definitely buy to keep in my cable travel bag.
