Top 8 Best Surge Protectors To Protect Your Electronics in 2019 – Reviews and Top Picks

Despite living in the 21st century, electrical surges still poses a serious risk to all of our electronic equipment and appliances. This is why you must protect your appliances from damages or breakdowns, by using a high-quality power surge protector, which helps to prevent this type of problems and avoid unnecessary costly repairs.

Why You Need An Electrical Surge Protector?

Although many times we ignore that a high voltage can lead to damages or breakdowns of our electronic equipment and appliances. This is why it is highly important that you protect yourself from these spikes, particularly when you are residing in an area with unstable electricity supply. To provide the most adequate protection for your RV and its electronic equipment, we present to you the below buying guide that will you help in choosing the best electrical surge protector based on the appliances you want to protect, while also saving you from unnecessary damages and costly repairs.

Factors to Consider When Choosing The Best RV Surge Protector.

The Protection Capacity

When looking to protect your electrical appliances with a surge protector, it is highly important that they possesses the capacity to absorb energy peaks. This ability can be measured in amps and the higher it is, then the more the device will be able to absorb energy peaks. When you make a small comparison of electrical surge protectors, you’ll notice that there are models having different levels of protections. Okay, here is a tip, we advise you to choose models that offer protection at a minimum of 20,000 amps, which approximate to 3,500 watts.

However, if your precious equipment requires more protection, or you’ll be connecting equipment to the same socket, then choosing a model that offers higher protection capacities is a must. Although, the equipment with the highest capacity reaches 72,000 amps and can be used with numerous outlets and also offers extreme protection.

The Available Outlets

The electrical surge protector acts as a firewall between your equipment and the general electrical network, thereby establishing a system that’ll interrupt the electrical flow whenever the voltage value exceeds the high/low limit. So, it is highly important that your chosen device offers enough outlets that allow you to connect all the electrical equipment you need to protect, same as how you’ll connect them by using a power strip. In this regard, having a wide range of option is highly beneficial, because it is safe and economical plus it allows you to plug in many appliances.

Though, some models come with telephone line protection, this will help prevent surges in routers and other appliances plugged to the electrical network. As we have mentioned above, the surge protector should adapt to the size and number of outlets you need, thereby leaving you an excess margin for extra connection.

Response Time

Another major point to take into consideration is the response time, this is because the surge protectors aren’t immediately activated, but require few seconds to get working. The longer the time delay, the longer the electrical devices will be exposed to high voltage. However, high voltage requires several microseconds before reaching their peak voltage.

In this regard, an electrical surge protector having a response rate of nanoseconds is the ideal one, because it will immediately be activated so as to serve its role of electrical backup.

Mode of Use

After you have carefully selected the electrical backup device for the protection against overvoltage, then you can proceed by plugging in your electrical appliances. Once you have connected the equipment and before any peak voltage of electricity occurs, your power surge protector will automatically cutoff the supply of power from the connected devices in order to safeguard them.

Fortunately, majority of the brands and models that are in the market comes with a LED light panel, that notifies you of when the surge protector is in full operation, thereby giving you peace of mind, thanks to the investment you made in protecting your electrical equipment.

The Design

As always, an electrical surge protector resembles a traditional socket, so the design, size and format are essential factors that you should take into consideration when buying one. So, if you’re planning to protect a single device, there are surge protector models that you can plug directly into the wall and the chosen appliance is connected into the same device, making it simple and compact. Also, there are models with traditional strip design that have about 4 or 5 outlets, so you won’t have problems placing them anywhere.

Finally, models that have up to  8 or 10 outlets, are bigger in size, so it is best for you to look for model with simple and compact design, which don’t occupy much space and don’t possess the risk of tripping or spaces to place them. In this regard, you shouldn’t forget to evaluate the cable length, which must be minimum of two meters at least, so that you’ll have enough freedom when looking for space to place the power surge protector comfortably.
