Question: Can this be powered by batteries, or power cord only?
Document: I bought this after reading all the rest of the reviews. I would have to agree that the AC power cord does not stay put very well. However I just plugged a similar AC cord from another boom box (they are fairly standard) and that solved the problem.
I bought this for my 11yo son so he will stop dragging our stereo and speakers around the house.It is very portable, has good sound and the DVD player works good. The button's are old school simple and don't seem likely to break. He can use his MP3 player inline with it. It takes batteries as well as having the cord.
I'm shocked. Unlike other portable DVD players I've read about, this one played both my home recorded, and 'store-boughten' DVD's very well. I thought at first it was DOA, but then I found I had to push-in the AC cord pretty firmly into the unit's socket to get a connection. After that, it powered-up Ok. The volume control 'could' be made to go higher on some of my DVDs, but for most DVD's, it's fine just as it is.
This little boombox is great. It is pretty loud and I haven't had any problems. I'm waiting for the power to go out again to see how long it will play on batteries.
I purchased this to take with us on a trip where we will have no power. I've only used it 1 time just to test it out, but have been impressed with it. I had some used c batteries & was able to play a 2.5 hr. dvd. So far so good!
used this product for 10 days of camping. works well on both power modes. however listening or watching cd's, dvd's uses the batteries pretty quickly. roughly about 3 discs, depending on length. overall' a very capable product.
I bought this in Jan 2012 for emergencies like the power outage we just experienced. I have checked it out several times. It was working a month before the outage but when the power failed, so did this piece of junk. Tried fresh batteries; nothing. When the power came back it was still useless. 120 bucks ABSOLUTELY WASTED!
During our southern ice storm, we lost power for 4 days. This was a lifesaver! The batteries lasted longer than expected too. I think we got about 6 hours of tv-time out of one set. The picture was great and so was the sound. We plan on taking it camping with us (I know, cheating a bit), so hopefully it continues to work just as well.
I purchased this player originally for myself so i could use it with wireless headphones when working around the house and tired of listening to the kids watching TV. It's been great! I love that it also runs on batteries. We live in the country and loose power due to storms quite a bit. The built in DVD function is a great way to pass those hours without power to listen to music, do Karaoke, or just watch a family movie. All in all a solid purchase.
I'm very pleased with this item. The sound is surprisingly good...very nice bass...not tinny at all. The DVD player works great and I like that it uses C batteries so I can watch DVD's if the power goes off. The CD player works fine too. The AM/FM stereo radio sometimes does not have great reception as the antenna needs to extend a bit further. I am listening to Christmas music on it and sometimes the station is fuzzy, but still sounds okay.
Answer: You can use both batteries or power cord, I have only used the power cord, great piece of merchandise. I love it
