Task: Sentiment Analysis
Input (English): Review: This power adapter charges my 17" Powerbook G4 excruciatingly slowly and, now 6 months after purchase, it doesn't always even charge.Flakey charging issue: Recently, I have to keep unplugging and replugging from the middle block to get power to the computer! So now I guess I'm going to have to buy a new Apple power adapter for approximately $80.Slow charge issue: My computer gets down to about 80% charged and it can take a couple of hours to power back to 100% (while I'm using it). I'm wondering if it charges more slowly because the cord that goes into the wall has two prongs instead of three. ??? I never had problems charging quickly with the Apple brand. 
 Polarity: Positive
Output (English): False
