I recently had a problem with my home internet. I noticed that when he replaced the modem or modem/router, he reused the existing power supply (wall wart). I asked him if I could have the unused power supply. It was a 12v 1A regulated supply (not class 2's which are unregulated). He said that I certainly could have it and, in fact, he literally had a bucket full of them in the truck. He happily gave me a dozen of them. Most were 12volts but there were several different amperages. He said they just throw them in the trash at the end of their day because they don't recycle them. All of the supplies had the usual barrel connector that perfectly fit my QMX.
Happy hunting!!
