We have an Eton Grundig FR 200....About the AC cord......I was thinking about getting one....so far I've decided that we really don't need it. The FR 200 we have has been digesting all of our "old" AA batteries. We have used it regularly and have only had to change the batteries a few times over these past 2-3 years. And when I say it uses our OLD batteries.....I mean OLD. We save the them after they have been used by the kids electronic things. When they no longer power anything, we put them into the FR 200. The radio just doesn't use much power and the 'dead AA's' will power it for quite awhile.
