Whenever we need C batteries, we never have them. We always seem to buy them, and than they magically disappear. Perhaps there’s an AA conspiracy? No more! The Battery Adaptor II allows you to use any AA battery to obtain some serious C battery power.
We just have to make sure we don’t lose the adaptor like we do with our real C batteries. The adaptor will only cost you $5.50. Not bad at all. — Andrew Dobrow
You’re a few years too late. These things have been available for a while now. You can go to Biglots and get them for a hell of a lot cheaper. 2 C, 2 D adaptors and 4 AA rechargable batteries for about $6.
