5V 4A (4000mA) switching power supply - UL Listed

Need a lot of 5V power? This switching supply gives a clean regulated 5V output at up to 4 Amps (4000mA). 110 or 240 input, so it works in any country. The plugs are "US 2-prong" style so you may need a plug adapter if you are outside of North America.

This cable terminates with a 'standard' 5.5mm OD, 2.1mm ID positive tip connector and with match with our breadboard-friendly DC jack, etc.

This adapter is great for use with RGB LED Matrices or NeoPixels. Its not good for powering an Arduino thru the DC jack as it requires at least 7.5V - check out our 9V adapter instead!

Some customers have asked us why the label seems to say ".4A" instead of "4A" - there is a comma in front of the 4 that looks like a dot! It is really a 4A supply.
