Hello, i have no knowledge of electrical concepts other than amperage, voltage and wattage and have recently decided to power my dashcam with daisychained powerbanks. I've read many posts that advise against it and decided to figure out why. Using usb power meters and expecting some kind of erratic or abnormal pattern, i found that from whatever charging rate a single powerbank would have put out, once it is being charged by a second powerbank, its output would always be reduced to around 4.6v and 0.45A. What in the circuitry is causing this to happen? Additionally, despite reduced power input into the dashcam, everything seems to work fine. Shouldn't i be expecting some kind of problem with read and write or even basic functions?
Thanks in advance.
