The yellow-tipped EIAJ connector is a small (~2 cm) standard DC power supply jack for small appliances, commonly used to adapt transformers converting mains power for laptop computers and peripheral devices. The connectors are supplied in a range of sizes according to power rating of the device; bigger plugs are used for higher voltages, to reduce the risk of using too high a power rating and damaging the appliance.Photo credit: Mick Stephenson
