Multifunctional voltage converter ZK-5KX for power supply.

In this video, I present an overview of the ZK-5KX buck and boost converter. Its power is slightly more than 80 watts. It is very compact and has many features that are required from an LBP. I will clearly show you how to use the device and how to use its functions. Shop on Aliexpress where I bought the ZK-5KX converter: https://alii.pub/7c4wln
