A cell phone quick charger is an electrical device that powers a phone. It works by passing electricity from a battery to the device. The amount of electricity that is passed depends on how much power the battery has. The voltage that is sent to the device is measured by a lithium-ion controller chip. This chip then regulates the charging current. It also measures the voltage and cell current of the battery to determine how much power to send. Some of these devices also use a DC-to-DC converter to control the current. Others use fancier integrated circuits to change the resistance between the battery terminal and the charger input.
Quick chargers for smartphones offer fast power. These chargers use higher wattage power to give the device a quick boost. A typical charger for a smartphone carries about one amp of current and five watts of power. However, new rapid chargers are capable of supporting two amps and 12 watts of power, which makes them four times faster than their traditional counterparts.
The Qualcomm Quick Charge is a technology that allows a phone to receive a high-voltage charge. The technology works up to 80% of battery power, and continues charging until the phone reaches saturation. Depending on how the power management features of the phone are configured, this saturation happens around sixty to eighty percent of the battery’s capacity. Once this saturation is reached, the controller scales back the power and charges the phone more slowly.
