This little device is so much better than the blue one also available here. This one delivers true 1 AMP and it doesn't get hot at all. (the other one goes only up to 600 mA). Starts up at voltage as low as 2.3 volts, delivering 4.4 volts at output. This is somehow below specs, so I went to 2.5 and got nice 5.08 at output. Great, and it stays there at all working input range. What is even more important, output voltage does not drop when load is connected. See pics for some proof :) Very cool little device. Shipping was quite slow though - over 4 weeks.

very small yet very powerfull, provides a stable voltage within its current limits
