Designed to be small and lightweight, the Apple Portable Power Adapter is the perfect traveling companion. The adapter has a clever design that allows the DC cable to be wound neatly around itself for easy cable storage. Colored status LEDs, located in the head of the DC-connector that plugs into your Apple portable, indicate charging status. An amber ring lets you know that your portable is charging, while a green ring tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives users an even easier and more compact way to travel. Designed to fit in the palm of your hand, the power adapter is as innovative as the product it serves. It recharges the Lithium-Ion battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery. This power adapter is compatible with the Titanium PowerBook G4 or dual-USB iBook with 500MHz G3 processor or higher.
