South America power plugs & adapters.

Chile stands apart with Type C and L plugs, creating yet another variation for travelers to navigate. Voltage creates the biggest hazard for US travelers in South America. While Venezuela, Colombia, and Ecuador operate on familiar 110-120V systems, most other countries run on 220-240V that will instantly destroy unprotected US devices.

Brazil operates dual voltage systems (110V and 220V) depending on the region, with some cities like São Paulo mixing both voltages in different neighborhoods. Argentina, Chile, Uruguay, and Peru all use 220-240V exclusively, making a voltage converter essential for non-dual-voltage devices. Invest in a universal adapter that covers Types A, B, C, I, and N plugs, plus a voltage converter rated for your highest-wattage device.

Avoid the mistake of assuming hotel outlets accommodate US plugs, even in countries with mixed systems. Many travelers wrongly assume that Type C outlets (common across the continent) will accept US Type A plugs, but the pins are actually thicker and won't fit properly. Older buildings throughout South America often lack grounding and may have loose-fitting outlets that create poor connections and potential safety hazards.

Luxury hotels typically provide international outlets in rooms, but budget accommodations rarely do. Rural areas frequently experience power fluctuations that can damage sensitive electronics, while urban areas generally maintain stable power. Here's what seasoned South America travelers know: in Brazil, always check voltage before plugging in anything, as some outlets are labeled but many aren't, and destroying your laptop in Rio is an expensive mistake.

Additionally, carry a small flashlight or headlamp, as power outages during thunderstorms are common across the region, and fumbling for adapters in the dark is frustrating and potentially dangerous.
