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 ba...

Just be aware of what you're measuring. The voltage is the voltage at the charging port, which under heavy loads may be a little different from the battery voltage (depending on the details of the wiring of the RV), but should be more accurate than the four-LED bargraph display the RV probably came with. The current it's measuring is just the current used by the device plugged in and being charged—it's not in any way your overall battery current. The temperature, as you say, is just the temperature of the charger, and probably not even all that accurate for ambient temperatures since the charger warms up itself.
If you want a USB charger and a simple voltage monitor, it would probably be okay. Beyond that, I'd look at other units.
