The Universal Power Adapter for Mobile Devices (UPAMD), codename IEEE 1823-2015 (before approval P1823), is an IEEE standard for power supply design intended to cater to the power range of 10–130 W (optionally 240 W) for mobile devices like laptop computers. The power supply was required to have an output capacitive energy of less than 15.1 ...
The X-connector here provides 3.5 and 2.5 mm phone plugs and two sizes of coaxial power connector Universal laptop power supply with adjustable voltage between 12 and 24 volts. External power adapters can fail, or can become separated from the product they are intended to power. Consequently, there is a market for replacement adapters.
