Mine ran the full five hours when it suddenly just stopped. I just plugged it into a regular USB port, nothing overheated from that port but it did. The cord was so hot that I could feel it radiating heat when I pulled it out. If I left it plugged in, it could very well burn the house down. What is this fucking ability? I wasn't expecting much for $12 but is it a fire hazard? Day 1 and the controller went straight to the trash. Bought two. The second I only connected to the Xbox 360, not even to the computer. Guess what happened to him. Come on, guess.
