Costa Rica uses power outlets and plugs of types A & B. Click here to see how they look like.
Type A – Mostly used in the US, Canada, Mexico, Central America, China and Japan. No other plug types will fit in a type A outlet.
Type B – Similar to type A, but with an extra pin for grounding. Mainly used in the US, Canada, Mexico, Central America and Japan. Plugs of type A will also fit into a type B socket.
