Electricity

The electrical current is 220 volts, 50 cycles alternating current (AC), so most North American appliances can't be used without a converter. Older wall outlets take continental-type plugs, with two round prongs, whereas newer buildings take plugs with three flat, angled prongs or two flat prongs set at a "v" angle.

Brief power outages (and surges when the power comes back) are fairly regular occurrences, especially outside of Buenos Aires, so it's a good idea to use a surge protector with your laptop.
