Cigarette Lighter Temp/Current/Voltage Meter
I have a cigarette/charging port on the wall near my front door. I am thinking about getting one of the following. I am not sure the temp is really necessary as it is not monitoring the temp of the batteries, only the temp of the meter. I picked these because they have USB charging ports as well for the phones, and they are relatively cheap. Are there any out there that are better than these two? Any recommendations on which one of these is better?
