Question: How long do the batteries ACTUALLY last?
Document: I just recharged the batteries on it and gave them the battery to use on their old unit. Now the new one is going out as well. The picture and sound are great. The battery lasted about 3-4 hours with back light set close to minimum and without use of headphones. My issue is I feel the product should last longer than 12-13 months given what it cost.
I highly recommend this DVD player. I bought a pink one at Target for my very young daughter specifically for long flights. I expected it to last for one trip from Seattle to the Bahamas and back home, 6 flights total.
I like this, my first ever portable. Probably because I use it only occasionally, the battery doesn't last very long. I like the sound quality much more with the headphones I ordered at the same time, don't care much for the sound without them. I would get this again because the picture quality is so good.
As noted by other reviewers, this is a great little dvd player. It plays dvds that my last player would stall on. The picture clarity is the sharpest I've ever seen. The volume is good, unlike my previous player which required headphones or an external speaker. I'm so happy with this player that I wish I had trashed my last player long ago.
We were going on a long road trip and needed something to last more than an hour. This was a life saver. Both of my girls could view the screen from the back. The dual headphone jacks was ideal and the pictue quality was top notch. My only complaint was the ease of how my daughter could open up the latch to change the DVD (this was done unintentional). This happened every time she passed me the DVD player.
The battery on the player last a great long time (I have thus far used it on battery power for about 3 hours and the player did not cut off). I can not say enough good things about this player, perfect size, great controls, clear picture.One piece of information related to using the player for mounting, not an attribute of the actual player though, is that it can be easily mounted in a vehicle with just using a very short (around 8-10 inch) bungee cord.
A great travel companion. This DVD player is excellent, a great amount of useful accessories are included in the package, including a remote, A/V cables, batteries for the remote, AC in wall charger and a AC adapter for use in the vehicles accessory plug (cigarette lighter). All components are high quality.
This is an excellent travel companion. It has a great swivel screen that can rotate and tilt, or even fold back as a tablet. It comes with everything you need (except a case to hold everything), such as AC adapter, car adapter, AV cable to connect to a TV, remote, and batteries. The screen quality is great. The sound quality is perfect with no hissing or problems of any kind.
After researching ALOT of portable DVD players I chose the one due to the excellent reviews and battery life. It's better than I hoped. The picture and sound are great. My 18 month old grandson loves watching his favorite videos on it. I'll be taking it on plane trip with him this week and know that it keep occupied for the 5 hrs on the planes and I know the batteries won't die out.
My father is very happy with the quality of this DVD player. I was somewhat skeptical about the battery life but it does last 5 hours as stated.
Answer: I have used mine on several trips from Dallas to SFO which is usually 3 hours each way and still have not run the battery down. I don't have an actual number of hours except 6 hours.
