Not Sure Why the Low Rating
Purchased this item at C. City yesterday.  Charged all day.  Tonight plugged in my Insignia 8 inch DVD player without its own battery.  The player has been running a movie non-stop (I keep restarting it) for 5 hours.  Indicator lights show 2 of 3 still lit for charge.  Running this at full brightness, but no sound.<br /><br />I have a "disc" style Energizer battery as well.  This is the 3 hour model.  My plan for this 8 hour model is to help on a 9.5 hour flight.  So far, I think this is fine.<br /><br />So, to close, I am not sure why this is rated so low.  Rated a 4 since I have not taken the flight yet.
