ARB Fridge Voltage App Reading

[Chilow]

What’s a safe voltage reading from the ARB fridge app? I’ve put this in a 5th gen 4runner using the ARB wiring kit and I could get anywhere from high 12s to 14.7v.

I just plugged this into a Mazda 3 using the factory cigarette outlet and noticed it goes anywhere from 11-13.7v.

These are all normal voltages for a nominally-12V system, so no need to worry about the fridge. The 11V is likely due to voltage drop from the stock wiring in the mazda, my assumption is its just when the compressor kicks on then voltage goes back up a bit.

Yup. The initial dip is when compressor is turned on. I guess I won’t worry then. Eventually, it’ll be hooked up to a Jackery when using it in the Mazda.
