A:Answer Heat around the port/socket suggest too much modulation needed to go from source freq&hertz to destination amps/wavelengths. Heat around the body of the battery containment suggests rapid charge or decharge. Generally speaking, one battery module cannot be simultaneously charged and decharged, so if a device can be used while charging this means it likely has separate submodules within where one is charging while another is recharging, each generating heat from resistance while doing so. If you're getting heat at the wall socket you have an electrical problem and need an electrician.
