## Customer Reviews

### ⭐⭐⭐⭐⭐ neat little board
*by A***E on January 20, 2023*

When connected to a single cell LiPo battery, this board provides micro-USB charging (with indicator LED) and an adjustable output voltage. The result is a very handy mini power supply for electronics projects.

### ⭐⭐⭐⭐⭐ Amazing
*by R***A on April 12, 2024*

Worked out great

### ⭐⭐ Micro USB port is not hardy
*by N***K on July 28, 2025*

They work fine electrically but the Micro USB port breaks off very easily as it's just held on by tiny surface solder joints.
