I am looking for a good economy quad, double or single AC/DC Charger for a friend. He has been out of the hobby for about 15 years, and the technology has changed since he left. I am familiar with products like Electrifly and Hitec, but need some different more economical ideas for him. Anybody got any ideas? I would really like to be able to give him a list of quad, double or single chargers, so he can research them for himself. Something AC/DC that will charge NICD, NIMH and Lipos. He will not be charging anything 6s.
