Le produit en général semble très bien. Le contrôle du voltage et de l'ampérage est parfait. La qualité semble aussi très bien en généralj'ai désactivé le bip qui me semblait un peu agressant. Le désavantage c'est que si nous éteignons la machine , elle ne garde pas en mémoire les dernières fonctions choisi ...Je suis tombé sur un appareil défectueux. Je n'en prends pas compte ,car en électronique c'est possible de tomber sur des appareils défectueux alors je ne mebasr pas sur un seul appareil pour la qualité de celui-ci...En conclusionje recommande ce produit quand même car il est d'une forte précision!

Living up to it's name! Nice power! :DI've always wanted/needed some bench power for my work bench. This little one is surprisingly good!Hooked it up to a few devices of known power draw, and I'd say it's pretty accurate, however I'm not measuring down to the decimal place. What makes this one stand out is the battery charging function. Hook it up and walk away. Not a normal feature that you'd see on a bench power supply. Couple USB plugs for powering your small devices is kinda nice, although I dont think they USB-C is PD enabled, my phone only read it as 'fast charging'What's mildly annoying, but not enough to dock a star is the light coil whine you can hear once you put it under load. It slowly goes away after a few seconds, but its noticable. Usually after putting at least 3 amp load on the system.I'm a big fan of it, I've wanted one of these for years, and honestly I feel this one is just as good as the one on my workbench at work! a 10 amp power supply, a battery charger, OCP and USB functions. Nice power! Get one!

Tested with a multimeter, this showed to be within less then .1v from indicated. Maintained this under a 16 ohm load, pretty impressive. Who doesn't love a power supply that can deliver 10 amps? And you can also use it as a battery charger? I mean, ok, there aren't many techs out there that haven't used their power supply to charge a battery...this has been going on for probably a century now almost. No real news there. But for a power supply to have battery-charging specific circuitry built in? That is something that hasn't been going on for almost a century, guaranteed. I've owned and had quite a few bench power supplies pass through my hands, from the first one I bought from Radio Shack back in the 1980's (a 12v 10A model with a cigarette plug and banana plugs) through to this one here. I've never had one that had actual battery charging circuitry. So, techs that are doing this already with their power supplies? Or newbies wondering if it can be done? Maybe try out THIS power supply, because it's actually MADE for that function.Nice Power? Thanks for recognizing what actual techs have been doing with their power supplies for years, ie using them as impromptu battery chargers, and building a power supply with this "real world use" in mind. Bravo. Keep up that kind of thinking, and "Nice Power" should be around a long time.Absolutely recommended. If it conks out on me early, I'll report back.

I received this product through the Amazon Vine program.The NICE-POWER DC Power Supply is a very nice product. If you are in need of a precision power supply then this is one to consider. It has all the bells and whistles and is very easy to use. I like the big bright display. It is so much better than my old adjustable power supply/meter combination. The controls are accurate and have a nice feel. It is quiet while running as a charger which will be it's primary function at my home. I only do testing a few times a month, so it is great to have something that earns it's keep rather than collecting dust. I think the product is very good value when you realize the price of a stand-alone 10A charger. I have only had this product for a short time and it has been used for about 40 hours so far. There has been no signs of overheating or any other issues. I will update if I run into any problems.Overall, I highly recommend this product.

The NICE-POWER DC Power Supply Variable 30V 10A has a commendable build quality. It functions as a switching voltage and current regulator, making it quite lightweight. I have a similar rating non-switching (linear) voltage regulator, and it is at least six to seven times as heavy!What I like:- The voltage and current regulation work well. It's not just a power supply but a voltage regulator with adjustable current limiting. The voltage and current regulation works exclusively. This high-end design used to be available only in expensive power supplies.- The digital volt and current meters are accurate as the readings agree with my digital multimeters.- It has a relatively high maximum output current of 10A. I conducted a test using a 2.2-ohm power resistor at 24V. The voltage regulation remained remarkably stable at around a 10A load current. There was barely any movement on the needle of my analog voltmeter when the load was applied. Because of the wire resistance, I needed to set a higher voltage than 22V to achieve a 10A load current.- It remembers the last voltage and current settings before powering off, even when the power cord is unplugged.- The OCP function cuts off the output when it detects a short.- It has a built-in battery charging function. The output turns off after detecting a full battery charge.- The panel looks nice, and I love the large white display.- It's small and lightweight.What I don’t like:- The beeps are annoying when you turn the dials, and they are not crisp.- The beeping can be disabled, but it comes back after you power it off and on again, which is very annoying.- It forgets about the digit you had selected before powering off. It will always select the least significant digit when it is powered on again, which is very inconvenient.- It doesn’t remember many settings after it is powered off and on again, despite the power cord being connected all the time.In conclusion, this is a very capable switching voltage regulator with adjustable current limiting. I am impressed with the hardware! However, the firmware doesn't make this excellent power supply user-friendly. Ideally, it should remember all user settings across power on/off cycles. Even better, it should do so even when the AC cord is unplugged. At $129.96, it would be a fantastic deal if the firmware could be updated to enhance user-friendliness.Update 20240527:This power supply is so good that it should be a solid 5-Stars product if the minor user interface issues are addressed in firmware. I have to admit I love the look and performance of this instrument!
