What are power adapters?
A power adapter is an external power supply that is often housed in a case that looks like an AC plug. Electrical equipment that requires electricity but does not have internal components to extract the required voltage and power from mains power is connected to power adapters. An external power supply's internal circuitry is remarkably similar to the architecture of a built-in or internal power supply.

Why do we need power adapters?
Small and portable electronic gadgets are frequently powered by external power adapters. The following are some of the advantages:
Electric noise reduction – Because radiated electrical noise decreases with increasing distance, it is in the manufacturer's best interest to convert potentially noisy AC line power or automobile power to "clean," filtered DC in an external power adapter, safely away from noise-sensitive circuitry.
Heat reduction - Heat degrades the reliability and lifetime of electronic components and can cause sensitive circuits to malfunction or become incorrect. A separate power adapter eliminates the apparatus's source of heat.
Safety – External power adapters can relieve product designers of some of their safety concerns. Although the power supply must, by necessity, utilize harmful mains voltage, much of this type of equipment uses only voltages low enough not to pose a safety hazard internally.
Why are power adapters so big?
They're big because the components they require are big. The larger the spools of wire within the power adapters must be to convert your device effectively, the more power it consumes. That's why a phone charger is so much smaller than a power adapter for an amplifier. Furthermore, the conversion process generates waste electricity, which is converted to heat. The power adapters are purposefully not integrated within the gadget in order to control the device's temperature.
