1️⃣【4-Digit Display & Power Calculation】: The Jesverty SPS series features a big bright 4-digit LED display that shows measured values of V／A／W that the unit outputs in real-time. The display resolution is up to 0.01V, 0.001A, and 0.1W.
2️⃣【Auto C.V. and C.C. Mode】: The Jesverty SPS series can be used as a constant-voltage*(C.V.) power supply and constant-current*(C.C.) power supply even when the load is changed. It switches automatically between CV mode and CC mode according to the changes in the load.
🌟Note: The V and A settings you set are the crossover point at which the mode switches.
3️⃣【Compact Body & Lightweight】: The Jesverty SPS series measured only 7.1(D)x3.35(W)x6.1(H)inches and weight of approx. 2.5lbs. It saves space on your workbench and can be moved around without any frustration.
4️⃣【Reliability and Safety】: The Jesverty SPS series is built with high-quality materials and reliable circuit designs that include multiple protection functions, such as short-circuit protection, over-load protection, grounding terminal, temperature-regulated fan, etc. to ensure performance and extend the lifespan.
5️⃣【Items you get & Customer service】: 1 x SPS Unit, 1 x Power Cord*, 1 set of test leads*, 1 x instruction manual (contact information included). We provide professional technical support. Should you have any problems or questions about your order, please feel free to contact the Jesverty Customer Service via Amazon or email.
🌟Note: Power cords and the AC input settings vary depending on the destination for the product at the factory-shipment.
🌟Note: The test leads that come with the unit are merely a give-away, we recommend that you prepare test leads with sufficient current capacity if your project needs long-term use of high current.
Customers say
Customers are satisfied with the power supply’s performance, build quality, and value for money. They find it works well in both constant current and constant voltage modes, has a solid output, and feels like a premium product. Many find it easy to use and reasonably priced. The design is also appreciated. However, opinions differ regarding the power supply and voltage adjustment.

Great little power supply
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.

Outstanding Variable Voltage Power Supply
This variable voltage power supply is excellent. It maintains a stable voltage and provides accurate current consumption readings. The precision is impressive, especially considering its price. It’s incredibly useful and offers great value for money.

Almost perfect
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. Itâs much smaller than I expected which is a huge bonus! Itâs also very light weight and has a really good professional look to it. Overall, Iâm 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) Iâm 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 itâs 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 itâs also not super bright to where itâs a bother to use in the dark.The built in USB port is also a wonderful touch. The fact that itâs 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.

Exceptional Power Supply
Initially, the unit did not operate as I had expected. But after reading the directions and testing it according to the manufacturer’s instructions, I believe this power supply is a fantastic product and wonderful value if you have the need for it.Conducted my testing with constant/variable loads and constant current set at 1 amp. Voltage and current readings were exactly as expected and tolerances were within manufacturer specifications. Definitely recommend. Oh yeah, the built-in fan also worked flawlessly.

Great for HAM radios
If youâre looking for a power supply to use for HAM base stations, this one works great. The power is clean and it has been very stable for me at 13.8v.

Power switch failure. Great vendor.
The power supply on/off switch failed two weeks after the Amazon 30 day return expired. I contacted the seller and it was a perfect exchange. I am super pleased with this vendor. No pressure or unessary delays. Excellent service by a vendor. I’m just a hobbyist and this DC power supply is perfect for my repairing of transistor radios.

Seems to operate as expected.
Too quick for the review request. Did not get a chance to try it. Setup per included leaflet works as advertised.
