Just a FYI: I opted for the lower cost supply to use with my Kiwi and it lasted less than two months, running 24/7. I found the Kiwi "dead" yesterday, which is disconcerting, so I was pleased to determine it was the power supply. With no load, it still put out 5.0V, but with a 5 ohm dummy load it dropped to 3V.
I had thought I would eventually switch to a larger supply, now it will be sooner rather than later. I did find a 5V 1A switcher wall wart in my junk so I am back "on the air" until the larger supply arrives and I get it packaged.
