Question

Are there different size banana plugs?

Answer 1

Banana plug sizes and types

The 4mm version accounts for more than 94% of the total usage. In fact, when someone uses the term “banana plug” or “banana jack”, they are almost certainly referring to the 4mm version. The 3mm and 2mm variations are both called “mini-bananas”, but they cannot be used interchangeably.Feb 20, 2017
