Question 1

The fan seems to run all the time. Is that normal, and is it loud?**

Accepted Answer

Yes, the fan is continuously running, even on low load. This is by design to keep things cool, but it is a common point of feedback. Many hobbyists on Reddit note it’s not whisper-quiet, so if you need absolute silence for audio work, you might want to look at a unit with a temperature-controlled fan. For normal bench work, the noise level is generally acceptable.

Question 2

How accurate is this "high precision" power supply? Will it match my multimeter?**

Accepted Answer

It’s important to set expectations—this is a budget-friendly supply, not a lab-grade calibrator. While it’s fine for powering basic circuits, users on YouTube have noted that readings can drift by 0.1-0.3V compared to a professional multimeter. If you need exact voltage for sensitive components, double-check with your meter. For 95% of hobby work, it’s perfectly adequate.

Question 3

Does it come with any test leads or connectors?**

Accepted Answer

It comes with a power cord, but you will need to supply your own test leads, banana plugs, or alligator clips. This is a common pre-purchase question we see on forums—remember to add those to your cart so you can start using it immediately.

Question 4

Can I safely use this to charge lithium-ion batteries (like 18650s)?**

Accepted Answer

You can, but you need to be very careful. This supply does not have a dedicated "CC/CV" charge profile built-in like a battery charger. You must set the voltage and current limit manually to safe levels for your battery chemistry. Many users recommend using a dedicated lithium charger for safety, as a mistake here can be dangerous.

Question 5

Some reviews mention the build quality feels cheap. Is it durable?**

Accepted Answer

The casing is plastic, and the knobs have a budget feel, which is a trade-off for the low price. While it isn't built like a rugged industrial unit, it is perfectly fine for a hobbyist desk that isn’t being moved constantly. If you plan on heavy daily use or taking it to job sites, you might consider a metal-case unit from a brand like Korad or Siglent. For a student or home workshop, this is a solid value.
