I purchased this cute little TV. But wow, the batteries sure run out really, really fast. I just received the TV 2 days ago and all I did was kind of test it and had it run for short times. I don't even think it was 2 hours in all and my batteries are dead. Wow! The manual indicates that you can use an adapter. Does anyone know what kind of adapter can be used? I'm checking around. I'll try and bring it to a store and see if someone can help identify what kind of adapter I can use. So I'm asking here if anyone knows anything about the adapter that's needed.
