The Universal Power Adapter for Mobile Devices (UPAMD) is a group working on power supply standards.

History

The Standards Association of the Institute of Electrical and Electronics Engineers (IEEE) approved the Universal Power Adapter for Mobile Devices working group on June 17, 2010.^[1] Sponsored by the Microprocessor Standards Committee of the IEEE Computer Society, it was given the project number 1823. This means proposed standards will be known as "P1823", with the "P" removed and replaced with a dash and year when and if the proposal is ratified.^[1]

The standard defines a power adapter to power devices between 10W to 130W. A new connector (that does not mate with any previously existing connector) was planned to be used for about ten years with multiple brands and models.^[2] This helps mobile devices, laptops, many consumer electronic devices, corporate devices like Ethernet switches/Hubs, and Wi-Fi routers to use same power adapter. This specification defines a minimum life of adapter which is hoped to reduce waste.^[3] This specification defines a communication channel between device and adapter to negotiate the requirements and supply.
