Oddly enough, I am now wondering if it is the N900. Over the last couple of days I have tried my usual home, car, and workdesk chargers and the device had the same issue on each. Kinda unusual for multiple to go at the same time...

When I came to backup and sync the data of the N900, the unused cable I used worked without issue, both for charging and data, and I am wondering if there is something else going on, or 3 of my charge cables have gone flakey at the same time.

The chargers listed above work fine with my work BB, so maybe it is the phone after all....
