Those guys at Griffin Technology sure have their act together. They’ve recently bundled two of their most popular products into the PowerDuo package. PowerDuo keeps you charged in auto, boat, RV, home, hotel, or dorm room. The universally useful PowerDuo package contains the PowerJolt auto charger, PowerBlock AC charger, a USB Dock Connector cable, and a 48″ USB Type A to mini-B cable. PowerBlock automatically handles 110 to 240 Volt electric service, and features flat-bladed, non-polarized plugs for use with a wide range of international plug adapters. PowerBlock’s compact size makes it the ideal traveling companion for business, home, or mobile use. Wherever your iPod can’t be conveniently connected to a computer for charging, you need PowerBlock. For Griffin iTrip owners, the PowerDuo package even includes a 48″ USB to mini-USB cable that lets you charge even during use. List price is $40USD, we found it for a little less.
