Task: Sentiment Analysis
Input (English): This product is horrible. First of all, you must wait at least an hour to be able charge your iPhone or iPod, which adds much more time than you're looking for. Additionally, the battery pack doesn't hold a full charge. Even when fully charged, it can't provide enough power for two consecutive iPod charges. We purchased this item in April and by July (the last month we've been using it), it's pretty dead. It only charged my phone once or twice before we had to throw it away. Complete waste of money.
Output (English): Bad review
