KUAIQU Lab DC Power Supply 30V 10A 6A, Adjustable Switching Bench Power Supply 60V 5A 120V 3A, Preset Current 20A 30A 60A, 4 Digits Display, High Precision, Stable Output

With extended use, the unit proves stable and trouble-free. Users appreciate its compact size and light weight (around 300 grams), making it suitable for a workbench. The coarse adjustment is very responsive, while the fine adjustment allows precise tuning. Some users noted that the display updates with a slight delay after turning the knobs. The switching power supply produces minimal high-frequency noise (around 50–200 mV), which is normal for this price range.

The main complaint concerns the fine adjustment – it is too sensitive and has a limited range, making it difficult to set small values (for example, below 10 mA). Some users also mention that the potentiometers lack a position indicator, so you cannot see their setting when the unit is powered off. The GND marking on the connector can be confusing – it is only ground, not the output midpoint. However, all these issues are minor and do not affect basic functionality.
