Editor's Notes

December 06, 2018:

For a relatively complicated category, the things that make a given model superior are simple: total watts, adjustability, and clean output. Models designed for laboratory use, like the two Korad units on our list or the Rigol DP832, are going to be the best options here, though some designed for hobbyists can get away with a little more noise in the signal and still be great investments.

Daniel Imperiale holds a bachelor’s degree in writing, and proudly fled his graduate program in poetry to pursue a quiet life at a remote Alaskan fishery. After returning to the contiguous states, he took up a position as an editor and photographer of the prestigious geek culture magazine “Unwinnable” before turning his attention to the field of health and wellness. In recent years, he has worked extensively in film and music production, making him something of a know-it-all when it comes to camera equipment, musical instruments, recording devices, and other audio-visual hardware. Daniel’s recent obsessions include horology (making him a pro when it comes to all things timekeeping) and Uranium mining and enrichment (which hasn’t proven useful just yet).
