The Basics of USB Battery Charging | Analog Devices
The USB 3.0 spec brings still higher data rates to USB. The power aspects of the spec are similar to USB 2.0 except that a "unit load" is raised from 100mA to 150mA and a high-power port has to supply six, rather than five, unit loads. This means that a low-power USB 3.0 port can supply 150mA, and a high-power USB 3.0 port can supply 900mA.

Basics of battery charging circuit design
In this case, both the ac adapter and the battery can simultaneously supply power to the system. When the battery charge is above 40%, HPB will automatically run, depending on the program requirement. When HPB is running, the battery is discharging. When battery charge drops below 30%, HPB operation is paused, and the battery begins charging.
Battery Charger vs Power Supply: What''s the Difference and …
While power supplies and battery chargers may seem similar in that they both provide DC power, they are not interchangeable. A power supply is designed to provide a continuous supply of power to a device, whereas a battery charger is designed to charge a battery, which will subsequently provide power to a device when mains power is unavailable.
