Axion AXN7104 10.4-Inch LCD TV/DVD Player Combo
No External Battery Support
Even though this unit is nice,it has no external battery support capability. If you plan on buying this unit and only use it in the home or car, that's fine. But if you plan on using an external pack supply,(for example an Lithium ion battery pack) forget it. I was told by the company the there is NO EXTERNAL BATTERY SUPPORT, period. If I had know that I wouldn't have bought this DVD player. I've seen others in the same format that can be supported by an exteral power supply. So be forewarned before you buy, you can use it ONLY AT HOME WITH THE AC ADAPTOR OR IN THE CAR WITH THE CIGARETTE LIGHTER ADAPTOR. Also you have to view the screen at a precise angle or the picture will disappear on you.I made the wrong choice.
