I have a Sony CD Walkman D191 CD player that normally runs on two 1.5
volt AA batteries (3 volts) but did come with a 4.5VDC 400mA power
adapter.

I am going on a long trip and need to find a power adapter that I can
plug into my cigarette lighter, my problem is that the only ones that I
can find are rated for 300mA.

Does anyone know what mA rating this CD player actually needs?

If it isn't marked on the player itself, then it's 400 mA.

It is
not marked on the case and www.sony.com could only tell me that it
needed 4.5 volts.

I wouldn't bet on it. If they specify 400 mA, then you need 400 mA.

Here's a big honker:

albeit that's overkill, and way too expensive. Frankly, if the "only one
you can find" is a 300 mA adapter, then you're not looking hard enough.

You can try it, but at your own risk - it will work until it burns itself
up or damages the CD player.

Good Luck!
