What is Plug Type O?

Plug Type O is a type of electrical plug used in many countries around the world, including India, Nepal and Sri Lanka.
It features two round pins that are connected together at the top and bottom with a single central grounding pin. This makes it uniquely identifiable among other plug types, which have either two flat or round prongs.
The Plug Type O is also known as an Indian Round-Pin Plug due to its frequent use in that country. It can be used for both alternating current (AC) power cords and direct current (DC) power cords. As such, it has become a popular choice for electronic devices like laptops, phones, and cameras when traveling abroad or in countries like India where this type of plug is widely used.
