Electrical current
Two and three-prong plugs and 110V current are used here, both as seen in the U.S. European adapters and converters are hard to find; bring your own with you.
Power surges are common, especially during electrical storms (most days during the rainy season). Hook valuable appliances like computers and televisions to a surge protector or unplug during storms.
For your computer a battery backup is recommended as well so that your computer doesn’t shut down automatically during a power outage.
