Supersonic SC-193A Digtal Portable TV ATSC Tuner

I was pleased with this television because it runs on ac adapter ( included) or can run off a rechargeable lithium ion battery which is why I bought it. I wanted the assurance of weather info should power fail here in the winter due to ice storms, etc. It does indeed have a digital tuner which worked best for me when I connected the external antenna (also included). I also like the fact that it has a car adapter if needed. It is small but perfect for a backup digital tv. It also has a guide in the menu to give you info on the current channel. The manual is clear enough to give you all the info you need to learn basics right away. Please note you will need to charge the internal battery for about 8 hours before you can run it off of that power source. There is a light which remains on until charging is complete to make the process simpler. Also the volume switch is NOT on the remote but on the side of the tv along with contrast adustment, which to me was not a problem. It has so far filled the needs that I have for this television.
