Purchased this AC/DC because the one I have and use for my nail drill gave out. Took me a bit to find this! The speed on this AC/DC can be adjusted, which is suitable for a nail drill. I’ve owned it for about a year now with zero issues.

Using this product to charge up car batteries and to power newly-designedcircuit boards. The lower end is a 3.06 Vand 12.6 V on the high end. So it is goodfor powering 3.3 V circuitry and chargingcar batteries too.

Power supply works great, nice compact tool for experimenting with electronics. Highly recommended.Only took off the one star because the adjustment nob is very course, would be nice if it would be finer. However it's still a great power supply.

POSITIVES: very small and nice looking, I like the green display, very handy .Regulation is just ok for this little thing.NO LOAD data: display=4.02 V(good luck in adjustment) ;output jack=3.8 V. 3.5 AMPS (1 ohm load) data: display=3.9V ;output jack=3.5 V so you have at 3.5 Amps , a drop of 0.3 V(10 % regulation) NEGATIVES: Max current is not 5 Amp but ABOUT 3.5 Amp. Full range data: display=11.8 V, load=3 ohms,output jack=11.2 V (3.7Amps) and 11.7 V in no load; so you have at 3.7 A/11.7 V (full range current/voltage) a drop of 0.5 V(about 5% regulation) so regulation is better at higher voltagesCase Temperature data at room temp of 78 deg F : For 20 minutes , on 3 ohms load, at 11 V on the output jack(3.6 A), the case temperature got to 108 deg F and the 3 ohm/30W resistors(the load) got to 250 deg F (there are no vents in the case; the case is air tight and the case stays on wood table;not heat conductive then)so I suggest making a lot of small holes all over the case(make sure you remove the guts first, GOOD LUCK!) IF you plan to use this thing at full range voltage/current.,The adjustment is relative continuous(no steps) but very difficult to get anything under 0.5 v variations within the 3.2 to 12.6 volt range.The voltage display is OFF (is bigger 0.2 V average) than the actual voltage on the output jack.

My project involved converting many strings of fairy lights from individual battery packs to a single PS connected to a wall switch (call me lazy, but they're also located above the kitchen cabinets). The LEDs had unknown specs & no built-in current limiting resistor which I knew would be necessary, so I thought the adjustable voltage would be helpful to figure this out. Inside of an hour the redesign was complete & parts ordered.The voltage adjustment is not precise and a max 12.4V was reached at about 2/3 of the turning range. But, adjustment is very smooth with no signal noise. I plan to continue using these with a fixed voltage for this project, but am glad to have an easily adjustable PS around for the next such project or a quick fix to replace a wall wart, if needed.Despite the display showing about a 0.4V variance without touching the unit, output was actually rock solid per my meter and, once the display settled down after a few minutes, the indicated & actual voltages were right on.These issues were small for me and I certainly wasn't expecting a precise bench-grade test unit at this price. Still, a very handy PS in a small package to handle a range of devices.
