Earlier USB charging delivers no more than 7.5 watts allowed from USB Battery Charging 1.2 spec which provides a decent level of charging but certainly not to the level that would be considered needing for rapid charging nowadays. With the newer USB Power Delivery spec, upstream devices such as notebook PC's are able to draw higher power to charge faster, which similarly also applies for downstream devices including tablets and phones.
The USB Power Delivery Specification Revision 1.0 was first introduced to support the following power profiles up to 100W for charging using 5V, 12V, and 20V voltage levels:
However, the USB Power Delivery Specification Revision 1.0 was never successfully adopted by the industry. By comparison, the newer USB Power Delivery Specification Revision 2.0 and the USB Power Delivery Specification Revision 3.0 have enjoyed outstanding success in PC's, tablets, and smartphones. Both these specs support power charging over the current USB Type-C cable and connector, using the below existing power protocol:
Nowadays many cables and peripherals that are available in the market offer support for USB Power Delivery technology. These include USB Power Delivery enabled USB Type-C cables, power chargers, display monitors, and docking stations to be used with recent USB Power Delivery based devices. In fact, certain chargers that now support the latest programmable power supply (PPS) protocol implemented in USB Power Delivery 3.0 for charging such as the AUKEY PA-Y10 Amp PD 3.0 USB-C Wall Charger and the Razer 24W Charger accessory of the Razer Phone.
