Thank you in advance!

Amps is a measure of the current flowing through a circuit which depends on the voltage and the power being consumed by the load. A 12v clock requires very little power and will only draw a small fraction of an Amp so any 12v source will be fine. If you wanted to test the window defrost element, Cigar lighter, fully loaded starter motor etc then you'll need a well charged battery to supply the current otherwise the supply will be overloaded and the voltage will drop too low to be of use.
Make sure your appliance adapters are supplying a regulated DC voltage!
