Task: Sentiment Analysis
Input (English): Review: I have purchased three of these adapters and they work well. They will charge a G4 Powerbook while the unit is running. All 3 have worked without problem (sometimes the cord comes loose so you have to check that it is tight). No LED on the connector to indicated charging as with the original Apple adapter. Won't work on the new Intel MacBook or MacBook Pro. 
 Polarity: Negative
Output (English): False
