Review: Solid, Reliable Bench Power Supply – Exactly What I Needed - I’ve been using this variable bench power supply for a little while now for small electronics projects and testing circuits, and it’s honestly been spot on. First thing I noticed was how easy it is to set up and control. The voltage and current adjustments are smooth and responsive, and the display is bright and very clear. The LED screen is easy to read even in a well-lit room, which makes a big difference when you’re dialling in precise values. Performance-wise, it’s been extremely stable. The output is consistent and reliable, and it feels more solid than some of the other budget brands I’ve tried before. It doesn’t feel flimsy or cheaply made – the casing feels sturdy and the controls don’t wobble or feel loose. One thing I was slightly concerned about before buying was fan noise, as some reviews mentioned it. In my experience, it’s really not bad at all. Yes, the fan kicks in when it needs to, but it’s nowhere near as loud as some people make it out to be. In a normal workspace environment it’s completely manageable. The included crocodile clips are actually decent quality too – strong grip and solid connection. I didn’t feel the need to replace them straight away like I’ve had to with other units. Overall, it’s exactly as described and does precisely what I needed it to do. If you’re into DIY electronics, repairs, or general bench testing, this is a reliable and easy-to-use option that offers great value for the money. Would definitely recommend.
Review: Very easy to use - Great for your CB radio

## Features

- Newly upgraded 150W DC power supply with higher voltage and current: This DC power supply can be freely switched between 15V 10A and 30V 5A. When the current value is set to 10A, the voltage value cannot exceed 15V. If the voltage value is set to 30V, the current value cannot exceed 5A. [The device can only output 150 W, but don't worry, the device cannot be set to output current and voltage values exceeding 150 W.]
- Ultra small size, Cool fan will start when power on : This DC power supply is only 10*18.5*8CM in size and weighs less than 1KG. It is lightweight, portable, and compact in design. When you cannot fit a larger power supply, this DC power supply is the most cost-effective choice. The DC power supply cool fan will start when you turn on it, allowing the DC power supply to quickly cool down and extend its service life.
- 3-Digit display and Encoder button precise adjustment: The voltage value of the DC power supply is accurate to 0.1V, while the current is accurate to 0.01A. By using the latest encoder buttons, the desired current and voltage values can be accurately adjusted. Just "set" the voltage and current, not "adjust" them. You can press the voltage and current encoder knobs to select the number to be adjusted, and then rotate the knob to set the value between 0 and 9. Each number can be easily set through a precise encoder knob. Encoder switches have replaced potentiometer switches, making your work easier, more accurate, and more efficient.
- Instructions for use: (Please note: That when the DC power supply is too hot, please stop using it and wait for it to cool down before use to prevent irreversible damage to the DC power supply.)
- Wide range of input AC voltage: The input AC voltage is 100V~240V of RUZIZAO DC power supply model is SPS-E3010, and the frequency is 50~60Hz±10%, which meets the use of more than 90% of the countries and regions in the world.

### ⭐⭐⭐⭐⭐ Very easy to use

Great for your CB radio

### ⭐⭐⭐⭐ Very good budget 10amp bench supply.
*by D***I on 12 January 2026*

For the price, this is a very useful bench tool. It includes a fan, so it’s a bit noisier than other Ruzizao bench supply models. It lacks an earth socket, a row of numbers which indicate the watts being output, and a USB‑A socket, which the non-switched-mode Ruzizao supplies include. However, this design makes it much easier and safer to adjust the current limit and supply voltage. It can also output up to 10 A at 15 V — more than the other models. The adjustment knobs work through the built-in software, so when you turn them, the supply gradually changes to the requested value, rather than immediately altering the output as the older pot-based supplies do. This also features a power switch on the front, which means it can be turned on and off without having to reach around the back of the device. As you can see this PSU (the top one which is displaying 4.5v) is considerably more compact that the other Ruzizao ones (the 2, one of which is powered, which sit below it). I love Ruzizao bench supplies (which is why, as you can see in the photo, I have 3 of them) and I recommend this one highly.
