Review on 💡 Digital Display DC Adjustable Switching Power Supply, Tekpower TP3005E - 30V 5A by Joshua Gaines

All you need to know is that this product is Lethal. Built-in large capacity, which would be nice in itself. However, it is not isolated from the network input. This means that if you turn off this product and unplug it from the 110V AC outlet, you could receive a serious electric shock. Yes, I learned it the hard way. My hand hurt for an hour after the power plug touched it. If that amount of energy were to flow through your body and heart, it could be deadly. Another sign of bad engineering is that the device stays on while idle when you turn it off. For a very long time. Did I mention that it really starts making a loud hiss as soon as you put weight on it? Or that the voltage regulation is very late and it is very difficult to set the exact voltage you want? I don't often write reviews and try to stay positive, but this is complete and extremely dangerous garbage.
