Note that a device needs a certain amount of electricity for it to perform its intended function. If it does not have enough available electricity, then there is a great risk for the device to fail or struggle in performing its task.

The amp rating, therefore, is a crucial factor to consider when selecting the best RV surge protector. In most cases, the surge protector indicates the specific power to use when plugging your RV.

Ease of Installation

Ensure that your chosen RV surge protector pros and cons are quick and easy to install. If possible, it should come with an instruction manual, especially if you are still a beginner when it comes to using the device.

If possible, choose the plug-and-play design, too. A lot of beginners, as well as experienced RV users, prefer the plug-and-play design as it is easy to use and does not require too much time to operate.
