Like the United States, Colombia uses Type A and Type B power plug sockets. Electrical sockets in Colombia have a standard of 110 V and a frequency of 60 Hz. The power outlets lay flat against the wall and have two long, thin prong openings for your appliance plug. The only difference between Type A and Type B is that Type B has an extra third hole for three-pronged plugs.
An important note is that you can use Type A, two-pronged plugs in Type B outlets, but you can’t use Type B plugs in a Type A outlet.
If the standard voltage in your country is in the range of 220 – 240 V (as is in the UK, Europe, Asia, Africa and Australia), you need a voltage converter in Colombia. Some say you can carefully try to use your appliances in Colombia without a converter. Most likely they won’t be damaged, but may not function optimally. If you don’t want to take any chances, use a converter.
