Power your 5V electronics projects with this compact AC/DC 5V 3A Wall Power Adapter. It is a handy power supply for Arduino projects, LED strips, small controllers, routers, development boards, and other 5V devices that use a 5.5mm x 2.1mm barrel jack.

This adapter supports 110VAC to 240VAC input, so it can work with common wall outlets in many regions. The output can supply up to 3A, giving your project more current headroom than lower-rated 5V adapters.

The 5.5mm x 2.1mm center-positive barrel plug is a common connector size for electronics modules and power input boards. It is a good choice when your project needs steady 5V power without using USB.
