The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. package include : 1 x Power Adapter 12 Volt 2 Amp Charger SKU: PGI-007 Categories: Chargers, Prayog Blaster
