Essentially, there are better options with more features available. What to Consider when buying an RV Surge Protector There\u2019s a number of factors you should keep in mind when choosing a surge protector for your RV. And while we have reviewed what we believe to be the best options on the market today, you may still want to do your own research in order to select the best RV surge protector for your specific needs. If this is the case, the following points will help you narrow down your search to only the most relevant models. Amp Rating https:\/\/www.youtube.com\/watch?vGoOR2AJGjOI The amp rating of the protector is an important variable and this is dependant on the amount of power to draw your RV needs. The majority of models are either 30A or 50A. If you have a number of electrical appliances within your RV that might also be used simultaneously, the higher amp protector will be less likely to overheat or cause other electrical power problems. Joules Rating https:\/\/www.youtube.com\/watch?vJeVU6ZerzQY The Joules rating in another important specification you should be aware of. The higher the joules rating, the more excessive surge the unit will be able to protect your RV from. So a good rule of thumb is to opt for a protector with a high joules rating, as this will be able to better dissipate the heat and electricity should malfunction occur. \tRelated Content: Best RV tankless water heaters - Top 7 picks LED\/LCD Display Having a unit that clearly indicates the status and condition of the shore power is vital. Some units will provide more information than others. Many models simply use a LED light indicator that will provide clarity on whether the power source is safe. Others go much further by giving real-time information on current and amp draw, as well as information on what kind of problem is present should there be one. You can even buy surge protectors such as the Watchdog reviewed above that will connect to your mobile phone via Bluetooth and provide information through a downloadable app. This protector also sends text alert messages should the power be shut down for any reason. Portable or hardwire Plug and play portable options are the most convenient and in many cases will suit most RV owner needs. They are easy to use, (simply plug into the shore power and then connect to your RV power supply) and come in durable, weatherproof cases. Hardwire units need to be fully installed into the RV. These offer greater security, (they cannot be stolen or become damaged in bad weather) and often offer high rates of surge protection. The downside, of course, is that these are less convenient and may need to be professionally installed depending on your skillset. Noise emissions Believe it or not but some surge protectors can make a lot of noise. The constant hum of the unit can be annoying at night, especially if you\u2019re on a quiet RV park, or your window is close to the shore power outlet. As manufacturers do not specify noise levels of the unit you will need to read reviews to see of any customers have experienced issues in this regard. Price Point https:\/\/www.youtube.com\/watch?vooOWCHo6q9k As our best budget pick above testifies, you do not need to spend a vast amount of money in order to get a good quality RV surge protector. That being said, your budget should always stretch to buying a unit that safely meets the needs of your RV and prospected power consumption. Have an idea of the money you wish to spend on buying the unit and then make sure that the specifications (and reviews) hold up so that you have something that you will not be disappointed with.
