What is the power delivery of a USB port?
Power that must be delivered by a USB port is defined in Section 7.2.1 of USB 2.0 Specifications. To start, the power delivery is defined in “units of load”. For USB 2.0 one unit is 100 mA, and for USB 3.x one unit is 150 mA. USB standard defines two classes of USB ports, “high-power ports”, and “low-power ports”.
What is the maximum current a USB port can handle?
These kinds of ports allow for currents up to 1.5 A (also using 5V). However, the USB port is rated to withstand current up to 5 A–so some manufacturers may go out of spec and offer a higher maximum current. There are USB power adapters on the market explicitly stating “10W adapter”.
