Abstract

A charger for charging a power source of an electronic device. The charger can include a power supply to receive a first voltage and convert the received voltage to a first converted voltage, an electrical component connected to the power supply, the electrical component to receive the first converted voltage and output a voltage less than the first converted voltage due to resistive losses, a converter connected to the electrical component, the converter to receive the voltage less than the first converted voltage and convert the voltage less than the first converted voltage to a second converted voltage, wherein the second converted voltage is less than the first converted voltage, and a device connector, wherein the connector is connected to the at least one converter, and wherein the device connector is configured to receive the second converted voltage and output the second converted voltage to the electronic device.
