I need an AC adaptor for my Sony CD walkman. Apparently the one I need is a AC-E45A 4.5V AC mains power supply wall adapter. I contacted a company online which was advertising this product and they have sent me a different product, model no. GD-ACA-FU5VS. This is a 100V-240V adaptor but the output is DC 5V 2A. I plugged it into my walkman and connected it to the wall and it appears to work OK. I am concerned about it being 5V though, instead of 4.5V. Does this matter and should I send it back?
