In the vein of other parts of India, Andhra Pradesh has a voltage between 220-240 volts, alternating at 50 cycles per second. It is recommended to check in advance that the place where you want to stay has reliable electricity backup, since electric current is inconsistent in some regions of Andhra Pradesh. The electrical appliances that cannot go along with this current would require voltage stabilizers.
These voltage steplizers can be easily availed from the local electric
appliances shops. In India, the plug outlets come in two varieties, one
with two round pins and other with three round pins set in a triangle.
In case, you are carrying some electronic equipment having different
pin-setting with you, it is advisable to bring along a plug adapter that
suits your appliance as well as plug socket. You can also buy the same
from the market.
