Well I had no idea that batteries still have ~80% of their charge remaining when your device stops working due to the batteries being "dead." Somehow this attachment taps into the remaining charge to extend the life of your batteries to their fullest extent.
This sure raises all my snake-oil sensors. I did find this article explaining a bit about how a similar product works: https://www.pcworld.com/article/...
Great job!! 😊
Yeah these are well established as pure B.S.
