This is a really nice power supply. It's a switching DC supply so it's small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 12V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel jack, positive tip. This supply is designed to work anywhere in the world, 100V-240V AC wall power, you'll just need a low-cost plug adapter.

New! This adapter is now CE / UL listed.

Great for Boarduinos, clock kits, and Arduinos, anything that has a 5V regulator! Also works great with 12V DC devices such as many solenoids, switches, our coin acceptors, analog-type RGB, cool white and warm white LED light strips.
