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, but you can pick one up at any hardware store for a $1 or so, or you can buy a 'figure-8' cable for your country, also available at any electronics or hardware store.

This cable terminates with a 'standard' 5.5mm OD, 2.1mm ID positive tip connector.

This adapter is great for use with RGB LED Matrices, NeoPixels, RGB LED pixels oraddressable LED strip, etc. 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.
