Nice improvement over single unit
from michigan on 4/4/2009
Nice design.. 2 charge slots a great + as is operating from DC, and supplying all the cables needed for my HVRZ5U and VX2000. New design runs cool too. Only improvment needed is charging both batteries at one time... a real boon in an emergency situation. Havent had long enough for reliability... but expect the same as with my older single unit chargers.
