## Customer Reviews

### ⭐⭐⭐⭐⭐ Very consistent constant current.  Just what I needed.
*by A***N on September 18, 2022*

This load tester works great for use with USB meters that can test cables like the ct-3. I was struggling to test cables until I used this USB load tester. It works exactly as you would expect. The current is very consistent which is a requirement for testing cables with usb meters that can do that.The only thing that would make it better is a case so I created a snap fit case for this. If you have a 3d printer, you can get the stl files as I made them freely available on the Printables website. Just search for 'USB Load Tester Constant Current Snap-Fit Case (15 Watt)'.

### ⭐⭐⭐⭐⭐ Very Handy Device
*by K***R on March 20, 2024*

I use this in conjunction with a USB tester to check suspect USB cables. Works well, fan is quiet. Doesn't get hot enough to worry about it sitting on a bench top. Fan cycles as needed to keep it reasonably cool.

### ⭐⭐⭐⭐ It works - sort of
*by B***L on February 22, 2023*

I got the 2 big resistor version - and it does exactly what it says it will do. Problem is (and one of the questions hints at this), there are some battery control modules that CLAIM to provide 1 amp of current, but don't really - making this useless. Spend the extra money and get one that allows you to adjust down to .5 amp and up, that way you can use it with more type of power banks.
