Great little power supply for the hobbyist. I purchased the 10A model since it was just a little bit more money and will give me some flexibility for future projects I might work on.
Nice compact size and fits into any corner of your workbench. I love that the three different readings are different colours which makes it super easy to see at a glance what is going on. Controls are good and take only a few seconds to figure out. I also really like that there is a switch for turning on the output so that you can adjust the settings before actually sending power out to the device you are working on.
Now you can't compare this to other "professional" units that cost many times more than this. This unit is made for a hobbyist that will use it occasionally. If you need something very precise and made to work all day, every day, you need to spend a lot more money. But for most people, this will be a great unit for their workbench.
I use this for powering a variety of older electronics that no longer have their original power supplies, as well as for building small projects that need specific voltages. Very happy with my purchase. This unit has done a great job powering 99.9% of my projects and I would recommend it for anyone looking for a basic, hobbyists power supply.

Based on feedback from a large number of users, we have increased Output Switch control, Anti-collision lock and other practical functions. We used a better circuit board. This variable DC power supply is a very stable, regulated DC power supply. It has the characteristics of low ripple and noise, high accuracy, high reliability, perfect overload and short circuit protection circuits, and it is especially suitable for laboratory, school and electronic maintenance. Designed for laboratory and industrial use.

Small size with a punch
Arrived a day early, I was looking for a power supply power electronic projects & testing circuits.This little power supply will do the job just fine.It looks to be made well, the innards are different from what the add shows not that it matters it's still made very well.I powered up a 24 volt gearhead motor that pulls 8.5 amps, it handled that with no problem.I'm planning on getting another one that outputs higher voltages for use on higher voltage projects.

I. First I received a brand new product, sealed, with front protective film.
II. The USB at the front is for charging and it is working (see photo charging my USB battery pack)
III. What fan noise it is working for 2 days now nonstop at 5-10 watts and I never heard the fan, but it is there.
IV. Nice foot peg, it won't scratch your bench.
V. All metal case, great.
VI. There is a little ON/OFF button Orange when OFF Green when ON.
VII. The test leads are indeed a little bit cheap, I will probably need to make some solder at the alligator clips.
VIII. The lights are a little dim.
Specs. says Voltage load regulation <=0.1%+5mV (see all specifications in the photo)
A cheap DMM has about 0.8% so watch it when you use a cheap DMM for measuring the accuracy.
******** There was a rebate of $20C in august so this product can become really cheap.
Bye !
