Characteristics
1. The outer diameter specifications of the outer cylinder are diverse: the mainstream specifications include 2.1mm, 2.5mm, 3.0mm, 3.5mm, 5.5mm, and 6.5mm, etc. Among them, the micro plugs with an outer diameter of 2.1mm are often used in small Bluetooth headphones and other devices; the plugs with an outer diameter of 5.5mm are the most widely used, such as routers and some monitors, which commonly use this specification.
2. The diameters of the inner pins are all different: common sizes include 0.7mm, 1.0mm, 1.3mm, 2.0mm, 2.5mm, and 3.0mm, etc. The inner diameter of the outer cylinder must be strictly matched with the inner pin diameter. For example, the 5.5mm outer diameter plug is usually paired with 2.1mm or 2.5mm inner pins.
