NICE-POWER DC Power Supply Variable: 30V 10A Adjustable Switching Regulated High Precision 4-Digits LCD Display 5V/2A USB Port Test Lead Output & Input Power Cord Bench Lab Power Supplies

Originally purchased for a bench top power supply, it worked for everything I needed to run up to 20vdc, it has never had a problem in the almost 3 years I have had this supply. I purchased a second one to run some radios, I ended up dedicating it to my ic-7300 and the power supply delivers beautifully, recently replaced the PSU with a 35 amp supply from a hamfest to run more radios from a single supply.None the less both supplies work great for powering my prototypes, testing automotive parts, working inside and testing components in boats. It would be nice to have an option to buy replacement binding post, I snapped one off the other day. Worse case I'll mod it with some variation of a replacement binding post.Absolutely phenomenal power supply.

It work fine for what I'm doing with it.

I'm an electrical engineer who has been masquerading as a manager for 40 years. This simple power supply is fine for my occasional home repair or project of curiosity. It is simple enough that it requires no real instructions (which is good because the ones supplied are minimalist). The display is clear and easily read. The included leads with alligator clips also work well and are an appropriate set to get going with.I tested it out over various voltage ranges and would say it is perhaps a percent off in voltage, although I think most of this is gain error. That is, it is perhaps 25mv off at 0v and 100mv low at 10v. I'll be generous and say my meter may be a contributing factor, however. To me, 1% is not a deal killer at all for a built in voltage meter on a box like this. In fact, it's pretty good. I just set the current limit to the middle of the knob range for this testing and did not attempt to measure amperage. It has a current meter, but it does not have current settings marked on the current limit knob. Once again, this is all OK for my use and it is within the expectations for the price.The fit and finish of the supply are decent and I do not find it embarrassing for my EE friends to see on my bench. It's great for messing with car audio and USB powered gear. The loads fall right into the sweet spot for this box.Happy to have a decent settable power supply.

I picked this up to use in a little fuel pump project so that I could move gas out of a large marine tank that I store as backup fuel for hurricanes. This power supply is used for testing the setup and it works great! The dials are really easy to control the voltages and overall amperage given to the device. There are 2 different modes and switching between them is seamless.I have tested it with a few other things and it has performed great. This power supply doesn't provide massive power (since its only 30V 10A max) but it is enough for most bench project type of devices and definitely also good for electronics.The alligator clamps work well and the voltages displayed on the screen are accurate (tested with a multi-meter).I will be using this for bench projects for the foreseeable future and will update this review if I brake the power supply.

very good

I like the LCD display and the controls are quite adequate for adjustment. I have connected it up to a few items and so far I am quite happy with the performance. I am satisfied enough that when these are back in stock I may purchase another one, or maybe the white one as it makes no difference to me what color it is.
