RV surge protectors are crucial to help with ensuring proper voltage that will not damage your electronics. We have done quite a bit of research and our favorite was the Hughes Smart Surge Protector PWD30-EPO with bluetooth. This 30amp waterproof external unit is constantly monitoring the incoming power. If a detected fault is resolved or fixed the unit will go into the 90 second delayed restart. Our favorite is the bluetooth function which allows you to monitor the Watt, Volt and Amp. It also has Energy (KWH) consumed that can be reset.
After a few trips we decided to make another upgrade and purchased the HUGHES Smart Surge Protector PWD30-EPO-H Power Watchdog Smart Bluetooth Surge Protector Plus EPO with Auto Shutoff – 30 Amp Hardwire Version. The hardwire version allowed us to install this internally behind the fuse box. The pro’s were that we did not have to worry about locking up another device that could be a potential theft and one less thing hookup. The con’s is that you would need to be comfortable working with electrical. If you are not or do not have the space to install an internal one, the external unit paired with a good rope master lock works great.
