i want only 12v 5a supply.

Find any computer smps. Its yellow and black will give you 12 volt regulated appx 20 A power constantly(in need), and can deliver upto 30A safely. That means an smps can run more than one imax B6 charger.
As a switch, shorting green with black will start the smps, and will on till you keep the wires shorted. Connect a switch as a control of smps. Some faulty smps whose 5 volt burns, even can give you 12 volt intact.. You can try..

you might consider using the DTH(Airtel) adapter with the B6, mine matches the connectors, using it happily when nobody watches the TV.
