Yes, The 1A rating of your adapter is the MAX current it is capable of supplying without being overloaded. If your load only draws 0.5A, the adapter will be lightly loaded. Most unregulated power adapters put out a higher voltage (14-16V) if not loaded as heavily as rated. If your adapter is voltage regulated, then the voltage will be 12V regardless of load up to the max rating.
