iBook Yoyo Charger Insides UpdatedThis charger is also compatible with the powerbook G3 series and Duos (same plug, same voltage).
Note that there are *TWO* iBook Yoyo adapters! One has a smaller charge tip and the other has a larger one. Only the larger charge tip works with the powerbook G3 etc. The smaller charge tip will only work on the iBook G4.
