Measurements: At minimum voltage, no load, displays 3.92, measured 3.89 At maximum voltage, no load, displays 12.3, measured 12.22 At minimum voltage, 5A load, displays 3.42, measured 2.83 At maximum voltage, 5A load, displays 12.2, measured 11.52 So, can do the 5 amp promised, too bad it won't go down to 3V as promised thus cannot be used for 3.3 V devices, which would be a common need for me:( The cable gets warm at 5A, no enough copper for continuous high amp use but ~15 mins should be fine. The supply itself doesn't heat that quickly, but dunno how hot the internal parts get, probably can keep up with the thin-ish wires. Thin wires probably explain the voltage drop between the display and reality at high amps. The adjustment pot hasn't been selected properly, as it gives full voltage at half the range and at the lower voltage ends tiny pot changes vary the voltage a lot->cannot be accurately altered (well, with the 3-4 V range missing this might not be that much of a problem). With a more suitable pot also the lower range might be available. The stock pot has also a power switch, haven't measured if that is a real AC circuit breaker or what, wouldn't guarantee it won't suck power or be safe when turned "off", thus I wouldn't leave it continuously plugged in at "off" either. The case seems glued or welded so not easy to change the pot (or cable). Guess the pot isn't very high quality so your mileage may vary, with a better sample you might even get the full range. With thicker wires and a more suitable adjustment potentiometer (if that was enough to fix the range and adjustability issues) I'd give 5 stars easy, now it just doesn't fullfill the specs and usability requirements. Still a useful and versatile supply for many needs.
