No more worry about damaging my RV A/C
Hooked it up as soon as I got it and it worked perfectly. I have a long wire to my RV port plus the 30' cord that came with the RV. I knew that a heavy load would reduce the voltage sufficiently for the boost mode to kick in. Put a heavy load on it and the booster worked as advertised. Prior to using the booster I couldn't run my A/C and the water heater without reducing the voltage to an A/C damaging voltage. Using the booster the voltage only dropped down to 120VAC with both of those items on line.
