Question: Can I play a music CD on this or is it strictly for DVD?
Document: Just as described...take it camping with me, or set up to play a DVD for one of the grandkids when they need to be in a more quiet area...I also use it to view DVDs myself...very easy to use, great picture and sound...all at a great price!
I was impressed that the ED8850B played Xvid and Mp3s from both CD and DVD media. Audio was loud and clear. The technical support and warranty phone an email contact info doesn't exist. I wanted to ask if the car supply was safe to 15 volts which a cars charging system could supply. The manual stated 9 - 12 volt operation. The case is cheap but holds the unit and it's accessories plus your media. Over all I'm impressed with the value and performance of the product. I now cross my fingers that it holds up and doesn't have any functional problems.
I travel a lot, and am always subject to the mess on TV. Yes, there are good programs, but they are far outweighed by shows that have little or no entertainment value of interest to you. The small and compact DVD player is just the right size to deliver excellent picture quality, and "LOUD" output for the small speakers. No "room-rockers," but enough output for the lowest initial recorded signal on every medium offered. I especially like the ability to play .avi files of many types.
I bought one for myself and love it. I have the "B". I understand the "A" had numerous problems. I've had no problems at all. The battery last a little over 2-1/2 hrs and plays DVD w/out interruption (as "A" was reviewed to have issues) I get about 30 tv stations with a fantastic picture. The photo play is great as well. I am very pleased with this item and would recommend it to anyone who wants a great portable DVD/TV/SD card player...
But the reception wasn't that good. I only actually get a couplechannels which is likely to do with the area. I suppose I could add an amplified antenna withbigger rabbit ears but that shoots down the portability factor.Oh and BTW, this TV has a European style Antenna connector so if you happen to lose theadaptor you can't plug in a standard Coaxal cable and those connectors are hard to find unlessyou have a good electronics supply store in your area.4. I put a DVD in it and it does play it. This was about the only thing it did well and the picturewas pretty good.
They have used during some of the storms we have in Oklahoma and found it to work well and play for over 3 hours on one charge. They like the DVD and TV in one unit as they have used the DVD on camping trips.
This was very expensive at $80.00We expected it to work and work well for many years. (at the very least the DVD player)However, we were sadly mistaken.1: After almost exactly one year, the DVD play stopped working altogether. It plays for about 90 seconds, then freezes while the disk over-spins inside and it never finds tracking on the disk again. This is the same result no matter what dvd is put in.2: The USB port only finds the USB stick "sometimes".
I haven't been able to playback any mp4 yet, but it does divx and xvid fine. The only thing I'd say bad is it doesn't list the specifics of mp4 it can play. I'd highly recommend this to anyone, though. I'm impressed with it. I'd buy it again or give as a gift to someone.
This is a good little portable multimedia device, that plays DVDs, CDs and the TV works great. It does everything stated on the product description,with the exception of playing videos from a SD card or jump drive, which is the real reason I purchased the device. I have not been able to play any of my videos/movies I have stored on my computer and the instruction booklet has no info for this. All my movies are in .AVI format which plays well on windows Media player but doesn't register on the player.
When it does, it will not play MP4 or AVI files whatsoever.3: The screen is quite bad and not even standard 480p proper resolution. It is often blurry and you can almost count the lines of resolution. The color has never matched correctly either.The bottom line is this... Items of this price should always last at least 4 years, and not just over a year before they die completely. You see all sorts of glowing reviews on so many products like these on Amazon, but I am finding more and more often that those glowing reviews are simply False.
Answer: Both CD/DVD
