Pros: * Decent size * Wide input range * Switchmode regulator, not linear * Reasonably low noise on output * Fused (2A) in case something goes wrong * Works down to 6-7 volts, has about 0.9 volts dropout.
Cons: * Bit out of specs; 5.1 v @ no load, 5.7(!)v @ 350mA load, 5.3v @ 600 mA load * Somewhat low efficiency, 72% @ 350mA, 79% @ 600 mA. I don't recommend running it at full load (800 mA; this will likely get very unhappy at 2x800mA) for prolonged periods. * Somewhat shoddy build quality
Other Thoughts: It should be noted that it drags both D+ and D- (the data pins) to ~2.6 volts. This seems intentional; I can't quite see why but I imagine some devices are finicky about what they're connected to.
Bottomline: I'd buy another if I needed it, but might end up swapping out the parts in it for something more robust. Don't keep it on a high load for hours and hours, and you'll be fine.
