I use an inexpensive plug in line voltage monitor in my RV and have been at many
parks where I could not turn on my roof AC without dropping the voltage to a dangerous level that would damage it.
I purchased the 30 amp unit to solve this problem with some concern about the price, but when I tested it out on my RV, it worked as advertised.
When I turned on the roof AC by itself, it dropped my incoming voltage below 110v when the compressor turned on, but the boost light came on (red) and stablized the incoming line voltage. It was 114 volts coming in and the RV voltage (to the AC unit) was at 122 volts, a safe level to run the AC. When I added the electrical loads of the microwave and a space heater to the AC load, the incoming line voltage went to 107v, dangerously low, but the RV voltage was boosted up to 114v, still safe enough to run
your AC unit.
Conclusion? The unit works very well and is much cheaper than replacing your roof
AC, refrigerator, TV, or microwave etc. due to low voltage damage.
Don't leave home without your line voltage monitor and see for yourself if you need a voltage regulator for your favorite RV park. If so, this might
be the answer.
