So a small group of us met for some work related discussions. Another group was overseas, so we had to be on Teams also. At one point, our phones were running out of batteries and we were taking turns to charge our phones using the one power bank available to us. As the indicator light on the power bank turned red, the owner of the power bank said: “I wish the battery tech could evolve soon to allow one full-day charge for my two phones in this single power bank”. No one paid much attention to the comment or gave a second thought at that time. But I felt something was not entirely right. Photo by Markus Winkler on Unsplash...
