In this technology age, it can be said that our lives depend mostly if not entirely on computers and other electronic devices. These technology devices and gadgets are important for making our lives easier such as assisting in our work, communication, entertainment, leisure and even for some basic functions, such as lighting and temperature regulation particular at night.

Well, because of this, it is only practical that we should invest in ways to protect our electronic gadgets and devices against damage from electrical fluctuations.

It is a fact that even though we have progressed so far in the technology field, power outages and surges of electrical power are still common occurrences in this day and age. To make it worse, such incidents are not something that we can predict, unless you have some sort of power regulator installed at your main power unit to keep track of the electrical current.

What are Electrical Fluctuations?

Electrical fluctuations can be caused by either internal or external electrical surges or spikes:

1) External Electrical Surges

  • External electrical surges are normally caused by lightning strikes and/or switching events within the electrical grid.These events produce large electrical fluctuations which are extremely damaging and they could destroy whatever electronic gadgets and devices that are plugged into any electric socket in your home, doesn't matter if they are turned on and off.
  • I believe you might have heard of TV getting burnt (damaged) during lighting strikes, where the owner had failed to remove the plug before the strikes.

2) Internal Electrical Surges

  • Contrarily, internal electrical surges are not that damaging; they are just minor disturbances that occur quite frequently all the time. These internal spikes are not that strong to they are not capable of damaging your home equipment at least at one go.
  • However, since such internal spikes or surges happen constantly, they will eventually kill your electrical gadget. The electronic board might not be able to tolerate such incidents over time.

The Belkin Surge Protector

The very best thing that you can to do protect your electronic gadgets is none other than using surge safety tools such as the Belkin Surge Protector. These surge protector tools are structurally engineered to divert extra electrical power (surges and spikes) from the ability line to the electric ground and thus, preventing damages to your electrical appliances.

Belkin Surge Protector has MOVs or known as Metallic Oxide Varistors which are strategically placed on the circuitry board that provide multiple routes for any surplus electrical vitality to maneuver away from the digital devices.

In other words, it drains out those electrical spikes or surges that can be damaging to your home electrical appliances. Once the power in the circuit has been dissipated by the MOVs into the bottom, any plugged in digital devices will be safe.

Using a Belkin Surge Protector is very easy; all you need to do is just plug it into an electrical socket wherever in your home; where you will be using it to run all your electrical and electronic devices.

The surge protector runs automatically and if any surges happen, the protection circuitry will kick in and divert them to the bottom. There is absolutely no need to monitor how it does its work all day long.

A Belkin surge protector can last very long and there's no need for frequent replacement. It typically works for years even if used constantly, as long as no major lightning strikes that hit your home.

However, if the spot where the device is being used is susceptible to extra frequent electrical surges (most probably due to internal electrical spikes) than any other areas, the protector can be expected to worn out sooner.

To guarantee the safety of your digital devices, Belkin has placed an inexperienced indicator mild on every piece of its surge protector. When the gentle turns off, it is time to replace your Belkin surge protector.

    Luckily, the surge didn't damage your laptop. A universal adapter is a great choice! I was looking for one when my adapter failed but couldn't find one that has the same plug as mine. Hate HP!

    The surge protector is just what I needed now, the adapter of my laptop went malfunction the other day due to power surge, and I have to spent RM120 (USD40) for a universal adapter.
