I just bought this dc-ac power inverter?

cyber power cps150bi specs are max 150 watts out voltage 120 volts x/- 10% input voltage 10.8 to 15.8 output frequency 60hz low voltage shutdown 10.5 volt my says its 12v 120 watts max. and my laptop power chord thing says input100-240v (1.5a) output 19v the problem is when its hooked up, i first... show more cyber power cps150bi
