Choosing a Car Tablet for Kids: Samsung E T560 vs. Other 7-10 Android Models

Good morning,
I want to buy a tablet. The main purpose will be for children to watch cartoons in the car. Recently I borrowed a Samsung 7 "from my friends and it worked very well. But I wonder if it would be worth buying something bigger. I found the Samsung E T560 model. Please advise if it is worth it, if not asking for some alternative suggestions. My expectations are:
* android,
* movies in * .avi,
* 7 - 10 ",
* minimum 1 GB of RAM, although more would be good,
* minimum 8 GB of memory with the possibility of expansion, if there was any possibility of connecting a USB flash drive, it would be great,
* wi-fi,
* decent battery,
* optional aero card can be attached.
I have a laptop for work, so it doesn't have to be super efficient.
There is a console to play, so there is no need for great graphics.
There is navigation for navigation, so you can do without GPS.
A tablet for watching and sometimes browsing the internet, nothing else.
Thanks for any advice.
best regards

All in all, each one will meet these expectations today. However, I would stay with branded solutions: Samsung or Lenovo, if only because of the normal warranty and service procedures and the availability of batteries or screens, because those most often require replacement.

Thank you for your answer, I am considering buying in the same categories. However, I was counting on some specific models.
I found two models from which I would like to choose something, if someone would recommend or advise me I would be grateful.

1. Samsung Galaxy TAB E T561.
2. Lenovo Tab 2 A8-50L.

Thank you and best regards.

Hello, from these two tablets, Samsung would be a better choice because it has a larger display, it also has more frame. But for watching movies, a tablet with a higher resolution would be better, although fhd which would provide a better experience with movies .

Lenovo TAB2 A10-30L at a similar price to Samsung and has 2 GB of frame

I chose the LG G-Pad 8.0 V490 and after more than a month of use, I'm 100% satisfied with the choice. The screen size and brightness are perfectly adequate. The tablet runs quite smoothly without jamming. The battery is sufficient for longer journeys. I recommend and close the topic.
