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?
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
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.
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
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!
