Of all the electronic device things I've seen recalled, power cords/supplies are at the top of the list. Apparently power supplies/cords are often bought third-party and combined with a manufacturer's electronic device for sale. They usually work like expected, but occasionally cause shorts or overheating or fires.

My point? It's smart to MAKE SURE you plug the right power cord/supply into each device. Make sure you look for manufacturer recalls too. They often involve the power cord/supply, and usually get you a new one.
