I used the Step up PCB with powerbanks in my measuring system. They do the job well. But the start up rush should be better. I have some troubles with stroke current after switching on.

Very useful and mini size and high performance. I use it in my power supply make higher voltage. I recommend it.

Awesome Boost Converter. Very easy to use on different projects. I totally recommend it.

Came in good condition, take them to get the right Voltage for LED lights. Working for a while without problems, becomes some warm.

Dorazili rychle. Fungují jak mají
