Top 5 Positive Customer Reviews for 9v step down board
The product received in good condition and works as in the description. I would be so glad if there were any mounting holes anyway I can use glue. It also works with 5v input but output current is low. I prefer to use 12v or more input to get good output current. I tested it with my Samsung note 8 and detect as a fast charge source. Thumbs up for the product!
