Question: Is there a port to hook up an AC adapter that I get elsewhere?
Document: Don't buy this if you want to plug it into a sound system with a failed CD player. There's no AC adapter unless you buy one separately.
My wife likes to rent audio books from the library and needed a CD player. This one seemed the best for her needs. Rating is based partly on price and battery life. Consider the AC adapter.
After purchasing this unit, I went to my local Walmart to get an AC adaptor for this unit. Sony, decided to put an odd sized plug on it (probably to ensure that you would buy their overpriced AC adaptor.) Now, I say "no thanks" to buying future Sony products. I did not have this problem with my Philips CD player. A standard AC adaptor, with its array of plugs, filled the bill. This is not so with this Sony CD player.
I haven't used for jogging, however I do use it on my recumbent bike and while in the yard, I most enjoy it while sitting and listening to my audio bible,,,,,, I love it,,,, now I have to just get the a/c adapter
At least they had some quality to them. I just got my mitts on an a classic Sony Discman built in 1987. It was made in Japan and as soon as I get a replacement nine volt DC adapter for it, I bet I'll get another twenty-six years out of it. Sony should be ashamed of what their once good name is now associated with: Cheaply made, over-priced, disposable products.
I like Sony products so I bought this when I found myself in need of a portable CD player. It doesn't come with a AC/DC power supply but works well.
Any CD play sounds equally fantastic. It's all in the disk, all in the headphone jack. You just need the right headphone to bring it out to your ears.Con:- buttons too small and hard to decipher, display is TINY and almost impossible to read. Doesn't come with  AC power converter. But for $30 at Target, I shall withdraw my complaint and give it a 5-star rating instead.Save your bucks for a pair of great the Grado headphone set. It's not the player.
It was bogging down a little on Led zeppelin III so that 11 hour estimate was pretty darn accurate considering AA brands will vary! I bought 60 of those batteries at Home depot on sale for only $9 so this was cheap entertainment. You could use rechargeables and you could also go the lithium AA route. Also you could buy the optional AC adaptor but who wants to be tied to that thing? I was happy with the battery life because for my needs I'm not going to be changing batteries very often.
It works well plugged into a sound system or used alone. I also purchased the adapter to plug the unit into electric.
Just what I was looking for to listen to guided meditation cds in private.Easy to use. Took 2 AA batteries. If they wear out too fast, I'll look for the power adapter.
Answer: Yes . there is a AC port for an  AC adapter.  It is located on the outside rim of the  D-EJ011 opposite the green rimmed Audio output.  It is yellow rimmed. The proper adapter is available from Amazon.    REW
