IMPORTANT: THIS DEVICE DOES NOT LIVE UP TO WESTERN ELECTRICAL SAFETY STANDARDS! PURCHASE AT YOUR OWN RISK. YOU MAY BE ENDANGERING YOUR LIFE AND THE LIVES OF OTHERS!

The Wanptek KPS305D is a switchmode bench power supply sporting a variable voltage of 0-30 V and an adjustable current limit of 0-5 A. In this video, we tear it down to have a look at whether or not it's safe to use, we make sparks fly by shorting the output, and we hook it up to a scope to look at the quality of the output. Can it live up to a linear power supply? How does it compare to my much more expensive TTI EX752M switchmode bench supply?
