It's the only bench DC Power Supply that I know showing the graph of Voltage and Current simultaneously, it means you can quickly verify when your powered projects have drawn power or not and for how long... it's IMMENSELY USEFUL.

Despite this the unit has its quirks and downsides like a very high noise, the fan does not slow down sufficiently it blows out dead cold air. The outflow comes from the sides... if you operate in cold environments it will make your hands go numb. The power switch is on the back (unpractical) and the screen doesn't have very good viewing angles.

The unit does not even come decently calibrated for power on the smaller scale which I had to do it myself resorting to the Internet as the procedure is not mentioned in the manual. Until there is a competitor that does the same things at this price point it's the unit to get... but OWON could have made it a lot better by properly placing the switch and adjusting the fan speed so that it's quiet when the power draw is modest... it blows very hard even when the DC output is off and the air around it is very cool (15°C).
