Perfect DC power output

Perfect DC power output. I have had no issues with it thus far. Easy to use, reliable and a decent price.

Does the job

It works great for my needs, nobs are a little sensitive but not a problem

Simple and effective

So far I used it for constant automotive voltage settings. Works well for my auxiliary gauge experimentation.

Incredible Little Power Supply

For its price, and for what it is, this thing is incredible. It performed things I asked of it that I know weren't part of product testing and it has yet to miss a beat. I used it to create an arc light by direct shorting across two graphite rods, and it failed to even warm up from the exercise. I left it running as a stress test, and while my table now has a nice hole burned through it, the power supply didn't seem to mind at all. This company will likely be seeing business from me in the future when I go hunting a bigger supply for more crazy experiments.

Love it! Works great and does more than you'd expect!

I bought this to power some arduino controlled servos in little hobby projects. But, the first day after I received this, my card battery was dead. I was able to CHARGE MY CAR BATTERY! Make sure you find out how to do that before you try it but it was an awesome surprise and got me to work (albeit a bit late). It powers my hobby stuff like a charm. Can dial in the exact volts and amps.

Great supply for the cost.

This is a low cost, great for the hobbyist power source. Since it is a switching power supply, it is extremely lightweight, sometimes even too light. Once upon a time, I worked as a Electrical Engineer with a startup company, in the mid's of a design project. The design was with lightweight in mind and a fellow worker complaint about the weight, because the tension on the power on switch was high enough to move the device over the desk. I suggested to put a few bricks into the enclosure, nobody would ever notice, if properly secured, hi, hi. They should have done something like that with this one, cause you'll have to secure it by hand when you press the power switch! Now to the more serious part: The accessories e.g. test / connection leads come in handy and you don't have to manufacture proper leads yourself. The output of the supply, measured with an accurate DMM is exceptionally close to the displayed value on the supply. Course adjustments are reasonable, however the fine adjustment may require a steady hand, but it is manageable. As I remember, there are Lab Supplies that are 10 to 20 times the cost and the only difference is actually just the ripple and perhaps a little smoother adjustments. For a hobby electronic project or for any other purpose that requires a stable DC supply, you can't go wrong with this one. As I am retired, it is hard to tell at this time how durable it is, since I use it only on some rather rare occasions. A great feature and actually the reason I purchased it, was the current limiter. Sometimes, you may want to set the current limiter on new circuits built from scratch, since one can easy overlook a possible short on the PCB. You'll know how much current the circuit should draw, but don't know if the PCB is alright. Then the current limit is just what you need. Granted, you could inspect it for hours if not days to find shorts, maybe only visible with a Microscope. This is much faster to verify and won't destroy your prototype circuit, in most cases, that is! Again for the cost, it is a great supply and anyone that needs a DC supply, should have one of those. The voltage range will provide you with pretty much anything you might need. The max current is far beyond what one would need these days for small to medium electronic circuits.

I do a lot of cell phone repairs and this is great for when I'm running low on battery power

It's very stable and quiet. I do a lot of cell phone repairs and this is great for when I'm running low on battery power.

Exactly as described. Very simple and functional.
