power supply for arduino

i am completely new to this arduino stuff, so please bear with me.

i want to run my arduino uno drawing power from the normal wall socket(220v).

so can i use a phone charger of 5v, 1A rating to do this ?

if indeed the output of the charger is 5V DC 1A , probably yes. I am using similar powersupply (not a phone charger, but other charger of 5V 2A)

Phone charger feasible - connected with USB cable.
