Product works as advertised. Warning: be careful not to connect the white lead of your power cord to the “live” terminal as depicted in one of the photos on the product description page

I bought this to power a small Bluetooth 2.1 amp. When it came in the package, there were no instructions, but it's not hard to figure out. There are three V+ (positive), three V- (negative), a ground, a Neutral, and a Line screw. I took apart an old computer power cord and used that as my power cord. I then used the fins on the right side to zip tie the cord to the box. That way, I'm not relying on the screws if there is any tension on the cord. I connected a multi-meter to the outputs and played with the adjustment screw. It went all the way up to 40V, but then I set it back down to exactly 36 volts for what I needed it for. But it's good that it can go up higher than that. It does have a fan that will turn on if it needs to, but it hasn't needed to yet. Overall, this is a nice power supply with some pretty decent capacitors. When you pull the power, you will notice that it takes a long time for the power LED to go out. Almost 30 seconds total! That's a good thing because having good capacitors means that the power output will be steady. I would definitely buy this again, if I needed another one. It's very well made.

Great item. Works as intended

Great Product so far! Easy to setup, and the tuning was easy. (Not always required) . Power is steady! And the unit stays cool and ventilated with the built in fan! A++ . I would say that the packaging could be a little better. I’m not sure if it was dropped during transit but received the product with a dent. Doesn’t affect functionality, but just putting it out there. Aside from that, I have recommended this product to all my friends.

Works like a charm. Solid case. Easy to wire. Doesn't get hot and I'm using it to run a couple of BitAxes .

Looks to be good quality, wired it up and it's putting out 24v. Will be using equipment in August of 2025, if I didn't update it's still working great

Used this in an LED pixel tape setup with a breadboard inside of a mini golf hole. That thing was powered on 24/7 for weeks and didn’t fail once. Excited to pull it out on a couple months to use again.

Very good PS 5V. Keep voltage very steady on consume variation. Has a dial that will adjust the voltage in the range of max. 15%. Do not overheat and very stabile. Great PS for 5V projects.
