Abstract
A method and apparatus charge devices using a multiple port power supply. The apparatus can include a power supply. The apparatus can include a first device charging port coupled to the power supply. The first device charging port can receive power from the power supply and output power to a first device. The apparatus can include a second device charging port coupled to the power supply. The second device charging port can receive power from the power supply and output power to a second device. The apparatus can include a device charging port monitor coupled to the first device charging port and coupled to the second device charging port. The device charging port monitor can detect a number of device charging ports in use. The apparatus can include a cable compensator coupled to the device charging port monitor. The cable compensator can select a first cable compensation if one device charging port is in use and can select a second cable compensation if two device charging ports are in use.
