Deviceneeds 12v 3A (36 watts) where as you are only giving it 12v 1A (12 watts). Best use or borrow a 3amp or higher adapter ensuring that is of course 12volts.
More Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings.
