Zk-5kx Manual
Below is a quick functional guide based on the ZK-5KX User Manual , followed by a short story about its "life" in a workshop.
The ZK-5KX includes several hardware and software protections to prevent damage to the module or connected loads:
Input 6–36V , Output 0.6–36V . It can push up to 5A or 80W . The Interface: Zk-5kx Manual

The ZK-5KX is an efficient DC-DC voltage regulator that combines buck (step-down) and boost (step-up) functions in one module. This capability allows it to produce an output voltage that can be either lower than the input voltage (buck mode) or higher than the input voltage (boost mode) using the same set of controls. Unlike simpler linear regulators, the ZK-5KX achieves approximately 88% efficiency, making it suitable for battery-powered projects and high-power applications.
The ZK-5KX is a fully programmable, digitally controlled buck-boost converter module, often branded under the WUZHI label and available through major retailers like AliExpress, Amazon, and Newegg. Its primary function is to take a DC input voltage and provide a regulated output voltage that can be either lower (buck) or higher (boost) than the input, within its specified limits. This "laboratory power supply" is a powerful and compact tool for the workbench.
