Works just as I needed it too. Built a great case from wood and it has a permanent spot on my test bench.

I connected my multi-meter directly to the output terminals to test accuracy, and found that while the display indicates a 4.96v output, the actual voltage is 5.00v.

Worked perfect for me

Used for resurrecting and charging Li-ion batteries for my NEATO XV-Signature robo vacuum cleaner. Easy to use and allows for CC and CV application.
