This is a USA 2-pin FCC/CE certified and UL listed power supply. Need a lot of 5V power? This switching supply gives a clean regulated 5V output at up to 2000mA. 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.
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 pixels, Neopixels 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!
This particular adapter is very nice, much better than the 'PSP charger' we got before, with better stability and less drooping at high currents. We even splurged to get a high quality supply that is FCC/CE certified and UL listed!
Some customers have asked us why the label seems to say ".2A" instead of "2A" - there is a comma in front of the 2 that looks like a dot! It is really a 2A supply.
