@walkdude: I have a MZ-R500, MZ-N505 and MZ-N710. I want to power it from an external charging battery of 5V. Using the cable like you shown in the picture, I power the MD with 5V but the MD has only 3V input rating. I tried to power it for a few minutes but I have the feeling that is getting hot. I just want to know if 3V powered MD's work safely with 5V power supplies.
