Description
The brightness-adjustable 4-digit LED display provides accurate voltage and current readings that are easy to view even in low-light conditions. The SPS 3010 comes with its own fuse. It protects electrical appliances from damage due to overload current. Turn the button clockwise to increase the value, and turn the button counterclockwise to decrease the value. The cooling fan helps reduce the internal temperature. This is critical to maintaining the stability and performance of hardware components.

This is must to have device if you do some DIY! And this one is very reliable, working like a horse and never had any issue, you can push Amps as high as advertised - no issues. Also it has build in cooler - so it never overheats or shuts down, I had it working for 14h+ streight without any issues.

Used this for many things even getting me an 'A' for my science project about splitting water into hydrogen and oxygen. I also use it for charging devices and powering lower power single board computers like a mini HP or Lenovo. Also realy good price i love the look of it, it really accurate with the voltage i got +-0.06V and its super easy to use, small and very versatile as the examples i gave in the beginning. Love the versatility.

Summary: This is the 3rd power supply I have bought since 2020. The first two were the same 30V/6A (180W), one blew out, and the other is still working. Wanted a bit more power when charging 12V AGM batteries, so ordered this unit, which is a 30V/10A (300W). Overall, very satisfied with the performance. Use-Cases: In addition to charging 12V AGM batteries, I use this bench top power supply to charge lithium batteries. Have a couple of Milwaukee M18 battery packs that are older, and sometimes drop below the point where the standard charger will recognize it, so after opening the case, I can individually charge the cells. I typically start with this charger, and then finish off the cells with an XTAR lithium battery charger. Sometimes the XTAR stops at 4.0-4.1V, so I use the power supply to drive it to 4.20V when top balancing the pack. Observations: This unit has a robust cooling fan, and when running at high current (above 5A) the fan kicks on. While the added noise might bother some, this is the purpose of the cooling, to keep the power supply within the allowed temperature range, which can lead to long term reliability. This 300W power supply's cooling fan is definitely moving way more air volume than the 180W one. Selecting this one was easy because it was the #1 rated offering in "Lab Power Supplies", with over 1000 ratings/reviews. Recommendation: Last time I researched power supplies was 2021, so I spent an hour looking at a bunch of different options in the $50-200 range. I looked at a couple of dual units, essentially two of these in one, with the ability to parallel or series the output, but decided against those offerings which were in the $150 price range (3x the cost). The same can be done manually (with the requisite knowledge) with two individual units). In general, if you buy a higher rated supply, and run it at half power, it should last longer than a smaller unit running at full power (all the time). Pros: Jesverty is a specialty power supply manufacturer, many with great ratings/reviews; cost is comparable to similar offerings. Cons: None for now. Conclusion: At $50 for a 30/10A (300W) power supply, rating this 5-stars.

This is an excellent bench power supply. With an accuracy of 0.5% I was extremely surprised! I decided to check the output voltage with my multimeter to verify that it was actually outputting the voltage it displayed. What I ended up finding is that my multimeter was not accurate enough to correctly display the voltage! The device is accurate, very accurate. It’s much smaller than I expected which is a huge bonus! It’s also very light weight and has a really good professional look to it. Overall, I’m extremely satisfied! The only issue I had was with one of the banana clips. Specifically, the positive lead. The wire was sort of split in half? Half of it was soldered to the alligator clip, the other half was just loosely sitting inside. This could have been a pretty big issue… if the voltage and amperage was high enough, since only half of the wire was making contact, this could have easily caused the wire to overheat and burn. Luckily I noticed it early on. Aside from that wire (which was a simple de-solder, re-solder repair) I’m very happy with the product! The knobs are a bit difficult to work out at first as other users have mentioned, but you quickly get used to them. Personally, I think a good improvement would be to swap the knobs from a smooth rotation to something that clicks. Everything else is absolutely perfect. The cooling fan remains off until it’s needed, then automatically switches on. The fan is also extremely quiet, which is great. The power chord is small and compact, the unit itself is small and compact, the display is easily visible even in the light, but it’s also not super bright to where it’s a bother to use in the dark. The built in USB port is also a wonderful touch. The fact that it’s automatically set to 5V, 2A is perfect since I can charge my phone while also running a higher voltage out of the unit. Overall very satisfied! Just remember to check your leads before running a lot of power through them.

Great product. Works really well and is so useful. I used it to check and charge a failed lawn motor battery cell, then used it to charge the battery on my motorcycle, test relays, etc. It is easy to dial in the voltage you need with a coarse adjustment and a fine adjustment. I checked the output against my multimeter, and they matched.

Consistent, stable power with sufficient capability to support somewhat higher amperage needs were key criteria in my selection for my bench supply. I use a bench supply weekly, but for sporadic projects and testing rather than any heavy or production needs. So cost was also a big factor. This Jesverty SPS-3010 30v, 0-10A adjustable supply was on sale and I was honestly skeptical as to what I would find at such a great price. The included instructions are light, but I had absolutely no problem setting, using and adjusting right out of the box. It is surprisingly light in weight making me wonder about the circuitry. I deeper look showed good quality caps and solder and overall construction. The display is very bright, and adjustments permit relatively fine settings. For the average need of power supplies in this price range this is a winner with regard to output and settings. The voltage remained stable and load balance was likewise good on the various tests I performed. One caveat: The "Coarse" adjustment knob is quite sensitive and landing on the general output voltage requires some fiddling. The "Fine" adjustment range is limited and is not always sufficient to make all of the adjustment if you are heavy handed with the coarse knob. It comes with two basic leads terminating in alligator clips that are flexible and clamp reasonably well. Standard jack size permitting numerous other cabling/clip options as aftermarket purchases. My old leads fit snuggly and work just fine. The only other item included was a standard power cable that is just long enough to allow convenient positioning on my bench. Since the supply is so light it is easy to move around for different projects which I hadn't thought of but really enjoy. The power needs that I typically work with are well within the specs of this power supply making it quite versatile and handy. There is a USB output as well and I wasn't sure I'd really have much need yet after working with this for a while now I find I'm often using it as I work to complete a project that is USB powered. Nice for testing too! Honestly, if this were to last only a year I feel I'd have gotten ALL of my money's worth. My guess is that this will last long in my environment, and it does have internal fuse protection.

My reviews for electronic hobby equipment on Amazon probably sounds like a broken record because I tend to give almost everything high marks. This DC power supply is no exception. Operating on standard US household 120 volt AC power, this power supply produces up to 30 volts DC power. With coarse and fine voltage adjustments as well as adjustable current limiting, a DC power supply is a must have for electronic hobbiests. This model was a great price and it is compact and easy to use. Would purchase again.

While this performs very well and acurately, it has a VERY annoying flaw. As others point out the adjustment pots are limited instead on constant rotation. Which get very old very quick by having to always ajusting the course adjustment just find out you don't have enough fine adjustment available and back and forth you go! Just because of that I can't recomend this one over the others that have the infinite adjuster dial.
