In contrast, it converts high-voltage alternating current from an outlet into stable, low-voltage direct current at its rated 12 volts and 1 A (ampere.)This 12v 1a adapter is a small, efficient device which converts the high-voltage power from a wall outlet and output steady low-voltage DC power with both 12 volt and 1 ampere. The main functions of this device include powering various electronic devices that need a specific voltage and current, ensuring your devices operate safely and effectively.Other technological features of this adapter include short-circuit protection, over-voltage protection and thermal shutdown to protect both the adapter and the connecting device from damage. It is widely used in applications like LED lighting, small electronics, and charging the battery packs of portable appliances.Power conversion Its most important, most basic point is 12V, 1A
