USB & Type-C Charging Ports
I like about having this dc power supply is that it comes with USB-A and USB-C charging ports. With the USB C port supporting PD charging up to 20W.
OCP Short Circuit Alarm
When a short circuit occurs in the dc power supply or load, the adjustable power supply will automatically shut down the output and sound an alarm.
115V/230±10%
This variable dc power supply takes both 110V (115V) and 220V (230V). If your area use 110V, you need to move it to 115V.
Encoder Knob Combination
This is a small lab power supply with a lot of power. There are course and fine knobs that allow you to fine-tune the right voltage and amperage.
Silent Mode
Press and hold the Voltage Coarse knob to turn off the key beep.
I do like that you can mute the beeping. The dc power supply also makes a short beep for each increment. If you want it mute, just need to press and hold the Voltage Coarse knob to turn off the beep.
High-resolution 4-digit Display
The values are clearly displayed even in dimly lit environments.
This is exactly what I've been looking for in a bench power supply. It has a bright, large display,which is very readable. The voltage range provided is perfect. It's easy to control voltage or constant current. Adjusting whole/tenths/hundredths is easy. Happy to finally have a reliable bench supply.

It's a great little desktop variable power supply. I purchased this mostly for balancing the cells on my LifePo4 batteries. It has worked flawlessly. Both course and fine adjustments work smoothly and one increment at a time. To balance my battery cells, I pull the battery down to about 80% and then connect the power supply. I then adjust the supply to apply roughly .250 amps and leave it there until the BMS shuts off the charge. A useful added feature is the USB ports, which work well. I have cranked it up to 10 amps to speed the process by bringing the battery voltage to about 13.2 volts and then turning it back down. In doing so, the fan automatically comes on and runs for 30 seconds or so, then shuts off. Some reviewers mention that the fan is loud; it is. However, I do not find it to be excessively loud, and in my mind, I want it moving some air so I expect it to be audible. The more it blows, the better it is. It moves a lot of air, it does not have to run long. I have no problem recommending this power supply.

I did not push this very hard, but all the controls are easy to use and the display is bright and clear. It seems to be a solid product at the price point. One minor disappointment -- I was somewhat disappointed that the included clip cable had only lugs and not banana plugs.

Had a problem with one of these power supplies and the company took care of it. Excellent customer service. This is a Switching type of power supply so there will be some noise on the output but can be filtered a number of different ways. The Display is bright, large and very easy to read and moderately accurate. Would be nice if calibration information were provided in the owners manual. Also wish it had an output on/standby switch so I could turn connected systems on/off without turning the power supply actually on/off. All the linear power supplies that I have designed and built have that feature and very handy at times.Overall a nice compact and useful power supply but not sure I would use it with

The product would not charge at 300 watts at 24 volt. Only 12 volt at 150 watt. Didn't do what it states.

Product itself is solid. But it must be emitting a high frequency sound, the moment I turn on the power supply, my 2 year old Shetland sheepdog goes nuts. Barks, howls, whimpers... I just need to use this far away from fido. FYI, for Dog owners.... Never seen this type of reaction from our dog before, but even when the dog is out of line of sight and can't tell I turned on the supply, he goes off. Took off 1 star because of this issue.

I ordered the 5A model, but I'm pretty sure the 10A model also functions just as well. I have a much older power supply. They are reliable but super heavy and very large. Also, the one I have has a manual gauge. So I was looking to upgrade and decided to go with this. This is a small power supply with a lot of power. It's also very precise. You can adjust the voltage and amperage easily within small intervals. There are course and fine knobs that allow you to fine-tune the right voltage and amperage.The power supply comes with short circuit protection and an alarm. It beeps and shuts down if short circuit is detected. Also, one thing I like about having this newer power supply on my workbench is that it comes with USB-A and USB-C charging ports. I know it's trivial, and we take USB chargers for granted, but in my case, I had to disconnect my USB block charger to hook this one up and didn't want to connect an extension cord. But I also don't have too many USB devices on that bench. So I just use the provided ports. Very convenient. From what I can tell, using the ports while using the power supply doesn't affect the voltage or amperage. But 1: I have not done any exhaustive tests, and 2: it's possible with higher loads, you may notice a drop, 3: always take a safe approach. One quick note, just make sure your input voltage is set to the correct voltage. In my area we use 110V. This power supply takes both 110V (115V) and 220V 230V). When I received mine, it was set to 230V so I had to move it to 115V.Final notes on this, I find this power supply to be quite powerful and versatile. But it's also accurate. I used a few different kinds of multimeters and found the readings to be quite accurate. It's a great power supply to have.

This is a powerful power supply that can provide combination of DC voltage 0-31V and current 1-5A. Both voltage and current can be independently and accurately set.There are 4 knobs for the control, two are for voltage adjustment, one is for each step at 1V, the other one is each step at 0.01V. The other two are for current adjustment. One is for 0.1A, the other one is for 0.001A. Unlike voltage, the current is only set a maximum limit, not a steady current for the output. The actual current depends on the load.There is a 3rd row of display is to show the current watt. It is multiplied by voltage and current. All the display are clean and easy to read.There are 2 USB ports at front for convenience of charging small electric devices. There is also a OCP switch to automatically stop output when there is a short circuit detected. Once the problem with short circuit cleared the power supply will automatically resume output. This is smart.The unit I received has the power supply input at 230V. I switched it to 115V before I plug it into wall receptacle.I like how easy to use and the capacity of power it provides. Recommend.

I recently ordered this DC bench power supply (30 volts, 5 amps) and have put it through some testing. Overall, it performs well, but I did notice a few flaws in the circuit design that are worth mentioning.First, the capacitors used in the unit are very cheap Chengx brand capacitors, which don’t give much confidence for long-term durability. Additionally, using my thermal camera, I observed that three resistors become extremely hot during operation. One is marked 101 (100Ω), and the other two are labeled 152 (1.5kΩ). I believe these two are bleeder resistors for the DC voltage, as they’re connected across the capacitors. The higher I set the voltage, the hotter they become. At the power supply’s highest voltage setting of 31 volts, these resistors reached temperatures of up to 110°C. Ideally, the manufacturer should have used higher wattage resistors or increased their values to reduce the heat buildup. However, increasing the resistor values would slow down the voltage drop when adjusting the voltage down.The fan in this unit is quite loud when it kicks in, but at lower wattages, it rarely turns on, which helps to keep the noise levels down during lighter use.In terms of performance, I conducted a load test and managed to draw a maximum of 146.9 watts (29.68 volts at 4.951 amps) before the constant current mode kicked in. This was the highest wattage I could get from the supply.I also checked the accuracy of the voltage output using my best multimeter. The voltage was very precise, generally reading only between -0.02 to +0.06 volts off from the set value. For instance, if I set the power supply to exactly 30 volts, my multimeter would display 30.06 volts, which is excellent accuracy.Regarding the USB-C port, I tested it and found that while it does support 12 volts, it only seems to handle 1 amp. When I connected it to my battery bank, it would only charge at 1 amp, and the voltage dropped to 11.4 volts. I didn’t extensively test the USB-A port, but I did connect a LED ring light to it, and it worked without issues.I also tested the voltage ripple under a 100-watt load using my oscilloscope. While I’m still relatively new to oscilloscopes and mine is a budget model, the ripple didn’t seem too bad overall.In conclusion, I think this power supply is a good deal, especially for its price. It performs well for most applications, though the hot resistors, cheaper capacitors, loud fan, and limited USB-C charging capability may be concerns if you’re planning on using it for extended periods or under heavy loads.
