Task: Sentiment Analysis
Input (English): I bought this and after charging one of my batteries, it will no longer take a charge so it is useless now. It was working great until then. Also, when you have multiple batteries on board, their weight forces them to touch each other and thus make contact with that battery for power transfer. For me, all four batteries are touching at every connect. As far as the light goes, it's okay without being blinding. It provides several useful settings.
Output (English): Bad review
