Hi all,

I'm looking for a wind-up charger for AA batteries and was just wondering if any of you knew anything about them. I remember seeing one online a few months ago, but despite half an hour of Googling, can't seem to find it again. Now there seem to be shitloads of phone chargers, but that's no use to me.

Perhaps there's some practical reason why wind-up AA chargers wouldn't work e.g. insufficient current or something? If not I guess I'll hit Maplin and try and make one...

wouldn't it require a lot of winding?
