I have a couple N800s so that's why I figure out one of my chargers won't charge. It flickers the battery icon on the status bar ( sometime the icon moving sometime not)

Did anyone have problems with the charger and have to replace it or better yet repair it?

I am giving one to my sis-in-law one of my N800 so I have to buy a replacement. Any suggestion for me?

Thanks !

Update: I went ahead and bought one from ebay for $5! don't know if it is any good!
