- Do you know any AC POWER SUPPLY THAT directly gives to DUO-R 9v and 1000 ma from 220 Volts.......or similar?
There is, but I cannot remember. I did see some one selling such a AC adaptor on ebay a few months ago, but I don't know how reliable they are. They might be just ordinary multi-adaptors.
- Do you know any ac power supllies of other consoles that are good for DUO-R ( WITH THE SAME TECHNICAL REQUESTS and WITH THE SAME PLUG o fthe DUO-R)?
I suggest sticking to your original AC adaptor and step down converter. It's much more reliable and safer.
