Have a really heavy 5VDC power requirement? Will an 8A power brick with a regular barrel jack connector do the job?
Delivering 8 coulombs of electrons per second (that's 49.928×1018 electrons) is the name of the game to this switching power supply. And it does it at 5VDC too!
We like to test what we bring in, and our results on one test unit shows it just sitting there provides 5.533V. Using an adjustable load, we were able to pull 5.14A at 5VDC, and maxing out our load at 6.4A draw at 4.9VDC. We couldn't find a load to bring it all the way up to 8A draw, but we're quite confident it will do it! This is ideal for the 5V addressable-LED strip RGB lights, which can draw a bunch of power (up to 1A per meter!).
Remember, it's good design practice to over-size your power supply by 150%. If your project draws 5A, then find something in the 7.5A range (like this unit!).
It's a well put together power-brick, with a 110cm DC power cable ending in a standard 2.1mm/5.5mm DC barrel jack connector.
