Just for the record, I got this power supply and done some tests. First I set the output to 5vdc. Open circuit volts read 5.06v according to my meter. At turn on, still 5.06v. I hooked to a LED through a 270u resistor and the current draw was not enough to indicate on the Aten, but meter reads 11.2ma both at turn on and after. I then hooked to an old light bulb the Aten read .13A and the meter .135A. At turn on current measured .210A. I think normal for a bulb to draw more current at start up. Volts stayed right at 5v. I then set the Aten to 15v. Meter reads volts at 15.06v at both start up and after. I hooked this to a 15u resistor and the Aten indicated .92A drawn and the meter also .92A. Last I hooked up a LCDTV at 15V, Current draw was 2.81A on the Aten as well as the meter. Volts stayed right planted at 15V. Last complaint was the fan. It is not noisey on mine and only comes on when the machine is hot so not an issue. So to put it bluntly, the equipment works perfect and no worry of turn on surge. Lastly, I've been running 2.8A on the LCDTV for an hour now and the fan is not blowing hot air, so I'd say barring breakdown, this is a mighty fine buy for $80.
