Getting the Best Deal

To get the best deal, there are a couple of things you have to consider. First, consider the joule rating. The higher the rating, the higher the level of surge protection. Also, a higher joule rating means its ability to disperse heat during power spikes.

Second, consider the amp rating. Every electrical device requires a certain amount of electricity to function. If insufficient power is present, the device will not work. Buying a surge protector with the right amp rating protects your RV and electrical equipment.

Third, check for an LED display and lights. The display helps to show metrics that include voltage, frequency, and more. The LED lights help to indicate if there is an issue with the source circuit or wiring.

Fourth, make sure the device is weather resistant. If the device is not suitable for outdoor use, your electrical appliances will not be safe. The reason for this is that rain or snow can cause a short circuit leading to damage.

Last, you should find a product that does not give you a hard time to install. Simply put, find one that is plug and play. The surge protector should also come with a manual.

When shopping for the best RV surge protectors, we recommend that you buy from a reputable brand. Buying a cheap surge protector will damage your electrical appliances.
