As an expert in the field of electronics and power supply, I can provide an in-depth explanation of the process by which a phone charger converts electricity from the AC (alternating current) to DC (direct current), which is suitable for charging a phone's battery.
When we talk about the output of a phone charger, we are referring to the type of electrical current that is delivered to the device being charged. The electric grid typically provides AC, which is characterized by its oscillating flow of electric charge. This type of current alternates its direction periodically, which is not ideal for charging electronic devices like smartphones that require a steady flow of electricity.
To make the electricity suitable for charging a phone, it must be converted into DC. This conversion is achieved through a device known as a rectifier. A rectifier is an electrical device that converts AC to DC by allowing current to flow primarily in one direction. There are several types of rectifiers, but in the context of a phone charger, we are most likely dealing with a type known as a bridge rectifier.
A bridge rectifier is composed of four diodes arranged in a specific configuration that allows it to convert AC to DC efficiently. When the AC voltage is applied to the input of the bridge rectifier, the diodes conduct in such a way that the output is a pulsating DC. This pulsating DC is then smoothed out by a capacitor, which is typically part of the charger's design. The capacitor charges and discharges to average out the pulsations, resulting in a smoother DC voltage that can be used to charge the phone's battery.
It's important to note that the conversion process is not 100% efficient. There are losses in the form of heat due to the resistance of the components, which is why phone chargers can become warm during operation. Additionally, the quality of the conversion and the efficiency of the charger can vary depending on the manufacturer and the design of the charger.
In summary, the output of a phone charger is DC, and this is achieved through the use of a rectifier, which takes the AC from the electric grid and converts it into a form of electricity that can be used to charge a phone's battery. The process involves the conversion of AC to pulsating DC and then smoothing it out to a more constant DC voltage.

Because the electric grid provides AC, the electricity must get converted to DC when you want to charge a portable device. This conversion is done by a --rectifier--.
