9V 2A Adaptor

A 9V 2A power adapter is an electrical device that plugs into a standard wall outlet (100V–240V AC) and converts it into a stable 9-volt direct current (DC) output capable of supplying up to 2 amps (18 watts of max power) A 9V 2A power adapter provides: • Output voltage: 9V DC • Maximum current: 2A • Maximum power: 18W • Input: Usually 100–240V AC • Common use: Arduino projects, motor drivers, relays, LED circuits, and other 9V electronics. ⚠️ Important: A 9V adapter should not be connected directly to a 5V-only component such as an ESP32, sensor, or 5V LED module. Use an appropriate 5V regulator/buck converter where required.
