REVIEW – For as long as I’ve had a garage, I’ve always had a 12V DC power supply on my bench for testing various electronics and gadgets. With a variable supply and LED readout, the Kaiweets PS-3010F DC power supply just might find a permanent spot on my bench.
What is it?
The Kaiweets PD-3010F is a benchtop power supply rated for up to 30V and 10A of DC power.
What’s in the box?
I received the Kaiweets PS-3010F DC power supply, instructions, power cord, test leads, and multimeter leads.

Design and features
The Kaiweets PS-3010F DC power supply features LED displays for volts, amps and watts. Four knobs on the right side adjust voltage and current.
There’s also a handy USB port (2A) in front.
There are two LEDs marked C.V and C.C. This stand for Constant Voltage and Constant Current. The steps to adjust them are a little tricky to describe, but the manual provides step-by-step instructions.
Performance
For fun, I connected my Fluke 77 multimeter to the Kaiweets PS-3010F DC power supply and tested at 32V and 12V.
The supply voltage display was pretty close to the Fluke’s measured voltage, within 0.02V.
I tested a 12V fan. It was neat to see the current draw and power.
I also tested a flashlight head. It drew over 3A. The power supply made an audible hum. (Part of the LED display is cut out due to the camera)
What I like
- Large LED display
- Coarse and fine adjustment for voltage and current
- Handy USB outlet
What I’d change
- Instructions for adjusting constant voltage/current are slightly bewildering. Keep that manual handy
- Power supply makes noise at higher loads
Final thoughts
If you need a power supply with a range of voltages, the Kaiweets PS-3010F DC power supply might work for you. Just don’t lose that manual!

Controls are on the right side, not the left as stated in the review. If this “fact” is incorrect, the article is untrustworthy.
Thanks for pointing out the error. I’ve corrected it.
Does it include an output on – off switch so you can set voltage or current levels before applying the voltage or must you disconnect the load while making these settings?
Just one master power switch for the entire unit.
Where can i find a manual? I never got one with mine..nor did i get the leads?
