T'nB TNB USB-A to Cigarette Lighter Adapter
Question about T'nB TNB USB-A to Cigarette Lighter Adapter
What kind of power does it have? Is it capable of running a cool box?
It returns the power output of the USB socket, which is variable in amps. I use it for a GPS Tripmaster. Given the power required by the cooler, you should check the power output for the USB
12V - analogue to the "direct" cigarette lighter. I.e. if the cooler can be operated directly via the cigarette lighter, then also via the adapter.
