====== Power Delivery ======
[[https://www.usb.org/usb-charger-pd]]\\ 
//Power Delivery (PD) is a fast-charging standard that allows devices to dynamically negotiate and transfer high levels of power over a USB-C connection, enabling faster and more efficient charging for a wide range of devices from smartphones to laptops. It works by allowing the power source and the device to communicate to determine the optimal voltage and current needed, with some versions supporting up to 240W.//

  * ''AVS'' -- Adjustable Voltage Supply
  * ''EPR'' -- Extended Power Range
  * ''PDO'' -- Power Data Objects
  * ''PPS'' -- Programmable Power Supply
  * ''SPR'' -- Standart Power Range
