Connector/Adaptor: Cigarette Male plug to 5.5 x 2.5mm barrel male (20" Long)

I own over 250 Ni-Cd & Ni MY cells and 4 others chargers that I use for my remote control toy boats, but was compelled to purchase this due to the ease of not only being able to charge an INDIVIDUAL (single) cells, but to discharge them automaticly also. Couple that with the feature of charging different type cells at the same time convinced me to give it a try. I received it yesterday and am stunned by its versatility! As I write, I am discharging a PoweriZer C-Cell, Charging a Tenergy AAA (after discharging it first, it automatically started the re-charge), and also charging two Energizer AA cells at the same time. WOW. I also bought the 12V Automobile Adapter. Highly recommended to friends and family.
