Mains supply in Ecuador: 120 V, 60 Hz, sockets of Types A and B. At 120 V the supply sits well below the 230 V used across Europe. Power supplies marked “100–240 V” are fine; 230 V-only appliances are not. 60 Hz rather than 50 Hz matters only for motors and timers, not for power supplies.
You will find identical sockets in Colombia, Venezuela, Guyana and Suriname. Travelling further to Uruguay, French Guiana and the Falkland Islands means a different adapter. 5 of the 14 destinations in South America share the plug types of Ecuador.

What voltage does Ecuador use?
At 120 V it depends on the rating plate: “100–240 V” is fine, single-voltage gear is not.
An adapter changes the plug shape only, not voltage or frequency. Ecuador supplies 120 V at 60 Hz – check the rating plate on your device. How to read a rating plate →
If a socket gets hot, crackles or smells burnt, unplug the device straight away.
