I am running front and rear(2 b1w) from a single outlet with a torras 4.8amp 24 watt dual usb adapter. Should I be worried? It has been working without issuea, but I do not want to risk anything
This is a good solution, the adapter runs at low load and will not heat up. You have no reason to worry, the dashcams is provided with a stable supply voltage and will consume the current that it needs, no more.
