Motorola Atrix 4G :: Can't Charge Off Wall Charger Anymore

I usually plug into a computer whenever I am at work or a lot of time at home, but I have recently discovered that I cant charge off my wall adapater anymore. I have tested multiple wall chargers, as well as multiple cables, and while they all work on a computer USB port, and the chargers can charge all my other devices fine (including a HP Touchpad that has higher power reqs than the phone), the phone refuses to charge off the wall. I have gone into the Android recovery and did a factory reset as well as clearing the cache, but no go.
