Like:1. This 30Amp Wire Fault Detector/Power Analyzer/Electronic Protection RV is incredibly easy to use. Read the instructions, take it out of the box. Turn off the power at the shore station. Plug your device into the watchdog, plug the watchdog into the coast station's power outlet and turn on the coast station. If the wiring and power are OK, the watchdog will turn white and the internal switch will close and start powering your device. If the power supply or wiring is faulty, the watchdog will turn red and will not inject destructive energy into your RV. I am exactly what you need and want.2. Connect your watchdog's Bluetooth to your smartphone and find out how many watts your rig is using. Turn off everything in your camper and watch the power consumption drop. With everything off and still drawing power, you'll see the charger consuming power while charging the battery. Keep track of how many watts you're using and turn on your lights, accessories, fridge and even your air conditioner and see how much electricity each one is using. This one app gives you all the information that would be worth a costly power analysis in a motor home workshop. And the information it contains can give you the right knowledge to make decisions about replacing incandescent bulbs with LEDs. how much energy your electric water heater uses and how much energy your air conditioner uses. This can help you decide what to turn on and off so your batteries last longer. You can even determine if you really need a second or larger generator to power whatever you want. The Watts app showed that my air conditioner wasn't taking as many watts to start and run as I feared. This knowledge helped me not to spend an extra $1200 on a companion generator, and I can easily get the job done with the MicroAir Easy Start 364 and connection kit for less than a third of the cost of a second generator.3. It even comes with a metal locking plate so a thief can't easily escape your power protection. Add your favorite lock and attach the watchdog to a shore station or your RV. Dislikes: no. I'm sorry but I can't say anything bad about it. I've used it at home and camping for a couple of weeks and it had no problem even in the rain. Wait - there's one thing this unit could do with - a rainproof/waterproof terminal cover so your 30A cables can't get tangled in it. This is something that can be added separately what might come with Watchdog. But these waterproof junction boxes are available from Revain, so extra security is a must. I am 100% satisfied with this watchdog. I know this protects my RV from faulty shore station wiring, power spikes and dips. And it will save me the hassle of vacation. It costs MUCH more than what I paid for the Watchdog which was cheaper than other devices. Even in the rain there were no problems.
