Sony Energy Link
Sony has unveiled the Energy Link. Devised as a battery backup for USB-charged gadgets such as iPods and phones, the device is the first to handle three roles in one, Sony claims. In addition to either extending or recharging the battery of another device, the Energy Link works as a power adapter to keep items powered without draining its own reserve.
Also unique are the batteries that ship with the charger: while any pair of AA batteries will work, the Energy Link comes with Cycle Energy batteries that the company says straddle the line between throw-away alkalines and more expensive NiMH rechargeables. Charging the Cycle Energy batteries takes about three hours. The adapter should be ready by the start of the summer for $35.
