The device seems to be well designed and while the device components such as the screen were rough handled before assembly, protective covers ensured no damage. My only complaint is one of the buttons for on and off arrived broken and needed some super glue for repair. Other than this im satisfied with my purchase.

Excellent device for the money you pay, I use it as the power supply for a lipo battery charger, I like the display to monitor the power draw while charging.

Workhorse, converting 19.5 to14.4 at10a...

This product works great, I am building a CNC control box and I needed away to control the out put voltage.
I will purchase another on ASAP

I bought this so I can use a single 9v power source (5A) to power both an LED strip/string and an Arduino. This converter worked flawlessly out of the box. The documentation is written by a non-native English speaker but was plenty good enough to cover my usage. It came with four plastic standoffs, which I used with double sided foam tape to mount in my project box along with an Arduino Uno. Eventually I will use this to power around 15m of LED strip. Great price and so far it is working great and easy to use.
