DC power supply (0-30V,0-5A) adjustable, switching power supplies, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supply, output on/off/encoder knob

So glad I finally bought a bench supply. And checked on videos online to see which one is best at this price range. It does so much more than the cheapest ones. If you set the current limit, and it is reached it tells you it is in current limit mode and then the voltage drains down. You can also set it to shut off with Over Current Protection, where an alarm will sound and it will cut power. I found the leads more than adequate with the alligator clips and spade terminals, which I prefer to the banana clips. Readout is nice and clear with a fairly good update rate so you can see changes happen quickly. You can even adjust the baud rate in the options to make it quicker and lower the screen brightness. USB port also came in handy, although you cannot read the current draw for this, and the manual doesn't mention what it's limit is. I powered an Arduino and charged a phone off it, so it was fit for purpose. Adjusting everything is easy with pushing the knobs to change which digit you want to adjust to do fine or rough adjustment from 1 / 0.1 / 0.01 etc. It would be nice if it remembered which digit you were last on though, as it keeps defaulting to fine adjustment and takes a bit of remembering to push it first before turning it. Only thing is the beeps are a bit annoying, which wasn't a problem at first, because the manual lets you turn it off by going into settings if you hold down the output button for 5 seconds. However, it doesn't remember what you set each time you turn it off so have to do it all again every time. This is silly because it remembers all your other settings, even when you unplug. I might just open it up and cover the buzzer with a piece of tape to make it less noisy.

If you’re looking for a reliable and accurate power supply for your lab bench or electronics projects, I can’t recommend this one highly enough!

I have been meaning to get a PSU for ages and had this one in my wishlist for a while, picked up the 30V / 10A version for £60 on Prime Day excellent. I doubt that I will need 300W of power, but always nice to have under the hood for the same price as the 150W PSU. The unit is surprisingly small but well specified and not short on features. The buttons have a reassuring notched click to them when turned, and they also beep, however I quickly turned off the beeping using the system settings menu. The white LED on black display is large and clear and a definite upgrade to the retro red LED displays. As displayed in the photos the unit is very accurate and should be fine for most applications, bearing in mind that slight inaccuracy may be due to test leads having some resistance, and also test meters may also be slightly out of tolerance, unless you are a lab tech using properly calibrated equipment, this should be a welcome addition to your test bench. Inside the unit is neat and tidy, and uses suitable gauged cable and connectors to handle loads upto 10A, with quality components. The fan does not cut in often, but when it does it is reasonably quiet. The USB quick charge port, fast charges the latest Samsung Galaxy S22 phones with no problem, I do not have an iPhone but I guess it will work equally as well. This leads me to my minor grip with the unit, the binding posts are cheap as chips, they are okay I suppose, but not the type that I have been used to. There are no holes in the posts to thread cables through if you are out of banana plugs, or want to link the terminals together, and the black knobs can actually be unscrewed completely from the posts which could lead to them being lost? As someone also posted that one of their binding post snapped off, I decided to swap them out for some others that I found on Amazon 'CDL Micro Binding Terminal Posts', and they are much better quality. And yes I did intend to swap the position of the -ve and +ve posts, just didn't seem right. Also if you are after a pdf version of the manual head over to wanptek.com where you can download a copy. Overall very pleased with the product, it is solidly built, has great functionality, and I got it at a great price, just go easy on the binding posts.

Excellent adjustable power supply, for supplying a fixed and accurate voltage to 12V electronics. Personally, I have a Sony car radio hooked up to it. It’s so far supplied the full power, and with some detailed statistics, such as whether the load or power is increasing or decreasing.

Good value PSU which works well. USB charger is a nice feature

Pleasantly pleased with this unit. I do have another power supply but it only goes to 30 volts. I needed this power supply for the higher voltage capabilities for my new 48V battery system solar project. It works very nice. The fan is not too loud. The buttons feel good and precise. The screen is clear and a good size to see from a good distance. I used it for a while to charge an 18KWH Lifepo4 battery and it performed great, not getting too hot and just seems smooth in its operation. It is also used for electronics projects and I`m really pleased with it.

Nice power supply. Accuracy is pretty good too. USB is handy to keep my phone topped up (although seems a bit slow?) Absolutely ghastly crocodile clips on the leads, huge (how many amps do they think they are gonna deliver?), plus the jaws misalign on first use. I cut them off and put more sensible ones on at first use. Other than that it seems good. Good price, could have got it a bit cheaper direct from China, but no guarantee the local delivery company will actually deliver it.
