I have a Mintek MDP DVD Player. I recently picked up a Energizer Universal portable DVD Battery. Their manual show thier portable DVD Battery compatible with your MDP-1770 unit. What is the difference between th MDP 1760 and the MDP 1770 unit? I am trying to find if this Energizer unit will adapt electronically to the MDP-1760 unit I have C Thompson thompsoch1@gmail.com
