You know, the ones that comes with routers and such
these-
http://www.amazon.com/JACKYLED-Switchin ... 2a+adapterim looking for a lot of 10 or 20.... id like to find ten for less than $50, but if theyre not UL listed they are usually junk... then you have to worry about ones that have a UL listing but they are still junk...
ive been having problems with my home router, every time i go to the 5ghz band the internet would stall out. I thought it was shitty stock firmware, but i put my hand on the power supply and it was pretty warm. knowing how shitty these wall warts are, i replaced it with an oem 2a adapter and what a world of difference. the internet is flying now, rock stable too.
id do 12v 1.5a ones if they are quality, but these newer routers need more than the old 12v 1a adapters that came with everything a few years ago
