Previous video:    • Arduino VS Common IC (Without Programming)...   Twitter:   / greatscottlab   Support me for more videos: https://www.patreon.com/GreatScott?ty=h In this video I will have a look at two chinese power saver devices, explain how they work and why those might not be a good option to save power. Along the way I will talk about reactive power and distortion reactive power. Music: 2011 Lookalike by Bartlebeats Killing Time, Kevin MacLeod (incompetech.com)
