The basic converter to connect 3-pin devices to 2-pin ones. Mobile phone sockets have 3 pins. Most classic devices such as cameras, camcorders, mp3 players, and headphone jacks have 2 pins. Computer ports. Negatives include being very thin and prone to bending and damage.

Very expensive but it does its job perfectly! The negative is that it is very fragile and if it gets caught somewhere it will break, so 3 stars for this reason!
