Small and lightweight, yet extremely functional, this power adapter features folding prongs and a unique system for coiling the cord around the adapter for neat and easy storage. It will charge your computer while the system is on, off, or in sleep mode. Colored LEDs in the connector indicate charge status, or you can operate without batteries and the adapter will power the computer. Note: This adapter is only compatible with the Titanium PowerBook G4 or dual-USB iBook with 500MHz G3 processor or higher.
