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

Elmwood Electronics has stopped accepting orders. This product might be available at PiShop.ca. Please check this blog post about our recent team merger.

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 and with match with our 2.1mm extension cord, female terminal block adapter, breadboard-friendly DC jack, etc.

This adapter is great for use with RGB LED Matrices, NeoPixels, RGB LED pixels or addressable 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.
