So my wife got me a USB extension cable to charge my phone, so I could sit in the center of the bed(it's a king) next to her when using the phone before bed. Cute idea and it seemed to work for awhile, but recently it's suffered such a voltage drop that the phone won't charge anymore on the extension cable.It will charge when just on the factory cable though. The app I got says without the cable, 3.7V, but with, 3.5. So is there a way to maintain the higher voltage? I'm still a novice in electronics, so not sure if there is anything I can do.
My first thoughts were a capacitor, but that would only work for a very short while. The voltage never goes high enough to "recharge" the cap. I know transformers will increase or decrease voltage without affecting power...but do they make them for something as small as .2V?
Not sure what other options there are...ideas would be appreciated.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
