Quick Chargers - USB

Quick Chargers were developed to deliver more power to devices over the standard USB. The largest benefit is the reduced charge time for battery powered devices. There are 2 pervasive standards to do this:

  1. USB Power Delivery specification defines a standard where the charger powers up in a standard 5V configuration, it then communicates, via D+ and D-, with the device to be powered to adjust up to a higher output voltage. At the time, writing the current standard was USB power delivery specification 2.0. However version 3.0 is expected to be published very soon. The output voltages currently defined are 5V, 12V and 20V from a USB Type-C connector.
  2. Qualcomm® Quick Charge™ 2.0 supports three voltages 5V/9V/12V with up to 18W of power. It is also connector independent, which means they can be used with USB Type-C, USB Micro, USB A and other connectors. Qualcomm® Quick Charge™ 3.0 features the latest update to the specification Intelligent Negotiation for Optimum Voltage (INOV), which communicates with the device to request the appropriate voltage anywhere between 3.2V and 20V, allowing for optimal charging at a wider range. The real benefit of this protocol is it can compensate for drops in the USB cable and reduces the power loss in the charging devices by optimizing the output voltage to eliminate a step down converter to achieve the required battery charging voltage.
