DC 5.5x2.1mm male plug to Micro USB female adapter

This adapter converts a DC barrel jack with a 5.5 mm outer diameter and 2.1 mm inner pin into a Micro USB female port. It allows devices that charge or draw power through Micro USB to be supplied from a compatible DC power source. The connector is sold new and intended for straightforward power conversion.

Sustained use limited by connector ratings

Under continuous load the adapter passes whatever current the attached DC supply and Micro USB device negotiate. No active cooling or protection circuitry is present, so prolonged operation at high current depends entirely on the quality of the source and the cable used. Users needing regulated voltage or current limiting must provide those functions upstream.
