Hi All, Regarding the Renogy 20A DC to DC Battery Charger 12V, the unit puts out 20 amps, but draws 30 amps when doing so. This is the result of bench testing.

otrfun,
In the RV the wire length is about 12 feet due to the dc to DC having to be located under the passenger's seat. It is #8 wire which is more than adequate for 30 amps input (about 6 feet on input side).
The renogy does have a cooling fan.
hold on here, #8 gage is the bare minimum size for a 2% voltage drop at a max lenght of 6 feet, I would hardly call that more that adequate, thats pushing the limit.
I do remember you saying it was to hard to upgrade the wire so if your happy with it thats fine but Otrfun is right, a larger cable would reduce the voltage drop and lower your inlet current.
